Introduction

The goal of this first gate is to develop a sound and coherent plan for the rest of the project. We must learn all we can about the drill and our group. By examining the drill and our group we can plan for any as many complications as possible and save ourselves time and energy in the long run. If we prepare and asses the drill and the group and develop a plan to move forward, we will be able to more effectively and thoroughly complete the rest of the project.

Section 2: Project Management

This section is for to propose a plan for two different aspects of the project. The first part will show the plan that is in place for the dissection and reassembly of the drill. The part following this defines our generic group responsibilities. It also has a concrete time line for each gate of the project, as well as what each member must do for each gate. While we hope everything goes to plan, problems may arise and the final portion of this section has the plan for any conflicts or difficulties that may arise in our group.

Part A: Work Proposal

While the basic structure and function of a basic drill is, we will gain a more complete understanding of the function of this specific drill by dissecting. Before the dissection is attempted, our group must develop a plan that will setup a procedure for the dissection and our group interactions. This plan must also attempt to anticipate any obstacles in the dissection and in our group so we can prepared for them as much as possible.

Necessary Tools

  • Phillips Head Screwdriver
  • Flat Head Screwdrivers
  • Skinny Simple Wrench
  • Allen Keys
  • Torque Drivers
  • Basic Set of Pliers

Dissection Process

One of the ways to reduce complications during the tool dissection is to ensure that the dissection is clean and uninterrupted. By examining the product and identifying the tools necessary to completely disassemble and then reassemble the product, we can help make sure that this is the case. Our first step is to remove the plastic casing of the drill. This is held together by screws, which can be removed with a Phillips head screwdriver. Casing like this is usually clipped together before it is screwed together. Because there may be clips like this, it would be smart to have a variety of flat head screwdrivers. These can be used for prying, or in case there are flat head screws inside the unit where we cannot see. After removing the case, we must release the chuck. The chuck must be removed with a single, open ended, skinny, simple wrench , so we will need a variety of wrenches to ensure that we have the right size. This is all our group was able to determine from the examination of the exterior of the unit. While we cannot be sure what the inside looks like we can make some educated guesses. There will be electronic components in the unit and from experience our group knows that these usually need to be removed with a set of Allen keys or torque drivers. It would also be smart to have a set of basic pliers in case we need to hold, handle or remove small parts. The reassembly of this unit does not need additional tooling. By examining the exterior of the drill and applying our personal experience, our group was able to develop a near complete list of tools that will allow us to dissect our drill with minimal problems.

Dissection Time Table

With this list of tools, our examination of the exterior of the unit, and our knowledge of what the inside of tools like this look like, our group felt comfortable that the dissection of our drill will take a half an hour to an hour, barring any unforeseen complications. What we can see does not seem to be too complicated to take apart, and we do not believe the inside of the drill will reveal anything that is beyond our abilities. However, if the inside of the drill is especially complicated it may take us up to two or three hours.

Perceived Challenges

While planning ahead may reduce the challenges we will encounter during our dissection, complications will undoubtedly arise. By identifying as many as we can now, our group will hopefully entirely avoid them or reduce their impact on our project. One of the main problems we foresee is the delicate and small nature of the parts that we will be working with. These parts can be easily broken or lost, so our group will need to use extreme care when handling and removing these parts. Another challenge will be the removal of the chuck. While we know that it won’t come off with our hands, we still need to determine what size wrench to use. Our group is also worried that it will be delicate and if too much force is applied, the chuck or its folder may be damaged or broken while removing it. The final area of concern for our group is the cord. While dismantling this unit, the cord has to remain intact. If it gets stepped on and pulled or accidentally cut, it will become dangerous to plug the cord in and the unit is no longer in the condition required by the project.

Individual Member Experience

Each of the group member has valuable individual experience that will aid in the completion of this project. All of the members of our group have a had some kind of shop experience and understand the how to handle and properly use tools. While this may seem basic, it is important that each group member can participate and aid in the dissection so the group can achieve the most complete understanding of our drill possible. Matt Barker has worked on and maintained RC cars, engines and go karts, so he has extensive experience in handling parts and tools both large and small. He has also produced a technical manual for the design of a rocket. This will greatly in aid the reverse engineering of the drill and our technical descriptions in our gateways. He has also worked with 3-D design and programming for UBSEDS. Arthur Higby has worked in construction and has spent time producing and reading designs. He will be able to help the group interpret any designs found for our drill or any products. If it becomes necessary to produce a basic design, Arthur will be critical in ensuring that our group will accomplish this successfully. Over the summer Christopher Landschoot worked as intern at G. W. Lisk, working with and designing solenoids. This experience with designing small pieces, especially small electronic pieces, will help the group when we look at the inside of the drill during the dissection. Michael Mason has spent three years working at eTech Surplus, an industrial surplus company based out of Rochester, New York. He has the ability to identify the name and purpose of a multitude of components because of his years as a product analyst at eTech. Our variety of backgrounds and personal experience will help in all further gates of this project.

Obstacles

While we all have our own talents and experience, there will be several personal obstacles to overcome. As engineers our training so far has been mostly in mathematics and we have not been presented with many real engineering problems. Because of this our tendency is to just try to brute force our way through a problem thinking there will be an obvious solution if we just write enough down. We need to learn to think as engineers and identify the problem, and outline what we need to do to find a solution in a clear and concise way before we even begin any actual work. In the same vein, I think we are all a little scattered and are lacking organization skills. This can be a problem especially during the dissection, where a lack of organization can lead to certain failure. As a group we need to make sure we stay organized and follow our outlines, otherwise we may forget a portions of the assignment or present them in an illogical way. One of major shortcomings is that this is these are the first technical documents that most of our group has written. In order to succeed we must apply the skills learned in class to know that we are properly executing these technical documents.

Part B: Management Proposal

It is important that our group has a clear definition of our responsibilities in the group. This way if there is a problem within the group, it can be more quickly resolved because each group member should already know what their responsibilities.

Group Member’s Role and Group Contact Information

Member Email Group Role
Michael Mason mdmason2@buffalo.edu Project Leader – Final Wiki Editor
Matt Barker mabarker@buffalo.edu Project Time Line - Technical Lead - Group Contact
Chris Landschoot crlandsc@buffalo.edu Product Historian and Analyst
Dave Nowak davidnow@buffalo.edu Project Engineer
Arthur Higby arthurhi@buffalo.edu Design Coordinator

Table 2.B.1 : This table shows what each group members role is within the group

As seen in table 2.B.1, each member has their own responsibility within the group. Michael Mason so far has taken on the role of group leader and editor. He has shown an ability to organize and focus the group, as well as assign tasks, we feel comfortable with him as the role of group leader. Mike was also the one who wrote and edited the Product Proposal and showed an ability to coherently and cohesively organize the group’s ideas in writing. Because of this he was chosen to be the Wiki uploader and editor. Matt Barker’s personal experience makes him an ideal candidate to be our technical lead. He has spent times working on technical manuals, already done computer design and programming for actual projects and has the most experience working with intricate machinery. This makes Matt ideal to guide our group technically (this sentence sucks come back to it). Throughout our time as a group, Matt has kept the group aware of our timeline and of any upcoming assignments so we have chosen him to be in charge of the project time line. Arthur Higby has spent time both making and following designs during his time working in construction. We have chosen him to be the lead on any design sections of the project because of his previous experience interpreting them. Chris Landschoot spent time before our group met researching the history of our product. His familiarity with the drill’s history makes it an easy decision to name him our Product Historian and Analyst. He will be the lead on any sections of the gates dealing with the drill’s past and its place in the current marketplace. Dave Nowak is our Project Engineer. While he does not have any specific responsibilities delineated, our group believe it is important to have a flex member. Dave will be responsible for unforeseen roles and aiding group members in finishing their section if it is more than one person worth of work. Our group will be sure that he is doing his share and that he has a responsibility for each gate, but as of now his role is somewhat ambiguous.

Project Time Line and Individual Role

After establishing our broad individual roles within the group it becomes to take a look at each project gate and see how these roles will apply to them. In order to have a thorough plan in place, we must also schedule and decide meeting topics.

Group and Meeting Plan for Gate 2 – Product Dissection

Gate 2 Meeting Timeline

Date Meeting Time Meeting Place Meeting Purpose
10-8-2013 5-6:30 PM Jarvis 338 Plan and Begin Product Dissection
10-9-2013 5-7:00 PM Jarvis 338 Finish Product Dissection (If Necessary), Develop Outline, Assign
10-15-2013 5-6:30 PM Jarvis 338 Review Rough Draft
10-16-2013 5-7:00 PM Jarvis 338 Review Rough Draft
10-22-2013 5-6:30 PM Jarvis 338 Finalize Wiki

Table 2.B.I.A – This table shows the meeting schedule, including date, time and location, and meeting purpose for Gate 2 of the project.

As the table shows, after Gate 1 is turned in, we have two weeks to complete Gate 2. Our group will begin right away by meeting on the 8th to plan and begin our product dissection. As stated in section 2.A of this document, our group believes that this should only take an hour to dissect the drill, which means that if all goes according to plan we should finish this in one meeting. If it does not, we have another meeting scheduled on the 9th that we can finish the dissection. The meeting on the 9th will also be when we construct the gate outline for the written portion of the assignment. Over the next week each member will work on a rough draft of their assigned portion. We will reconvene on the 15th to examine the rough drafts of each member, comparing them to our outline and the original assignment to make sure that they are complete. We will finish this during the meeting on the 16th and also assign any final revisions during this meeting. Our group will meet one more time on the 22nd to make sure we are happy with our final product before submitting the assignment on the 23rd.

Each group member will have their own share of responsibilities for the gate. Matt, as our technical lead, will be in charge of the dissection. While all group members will participate, Matt’s technical experience will be our guide in our dissection and we will follow his lead and direction. He will also be in charge of writing the "Ease of Disassemebly" section, since he was the lead during the dissection. Mike will be in charge of the outline development, editing and wiki submission for this gate. As Project Leader, he will also make sure each group member is assigned a portion of the assignment and that they are completing. He designed the current project timeline and group assignment, so he will evaluate their effectiveness and recommend adjustments for the “Cause for Corrective Action Section”. Since there is not much going on with the history of the drill in this portion of the Project, Chris will be in charge of documenting the dissection process. This will involves taken pictures and notes during the dissection process and then typing and organizing the notes and pictures for the gate submission. Arthur’s familiarity with design will make him perfect for the “Document the connection of the subsystem” Portion of the gate. Dave will assist Arthur in this in his role as a floater, but more importantly he will look at the recommended actions of the gate, namely revising Gate 1 and begin looking ahead at Gate 3.

Table 2.B.II.A – This table shows the meeting schedule, including date, time and location, and meeting purpose for Gate 3 of the project.

Gate 3 is the Product Analysis portion of the project. This gate involves a thorough examination of the individual components. As the table 2.B.II.A shows, our first meeting for this gate will be the day we turn our Gate 2 in and the meeting will start with us reflecting on our Gate 2 and discussing any changes that need to be made. After this discussion we will develop an outline for Gate 3. The next meet will be the following week on October 29th. In this meeting we will begin the component documentation. This will probably take longer than the two hours meeting so we will continue it the following day. Before we complete this meeting we will make sure each personal knows their personal responsibilities for the written portion of the assignment, which is to be completed for our meetings the following week. The following week on the 5th and 6th our group will go over the rough drafts and discuss any changes to be made. The paper will be finalized on the 12th and placed on the wiki. During the meeting on the twelfth we will discuss our Gate 2 grade and discuss any changes that need to be done to our procedure.

This Gate will require different applications of our group roles. Similarly to Gate 2, Mike will again discuss the “Cause for Corrective Action” assignment because of his role as group leader and timeline designer. He will also be in charge of the outline and role assignment for the paper. As our Product Analyst Chris Landschoot will be take the of the documentation of the components of the drill, but all group members will be at the meetings while this is taking place, so they will assist. He will also be doing the “Component Function” portion of the writing. Our technical lead, Matt Barker, will take care of the “Engineering Analysis” portion of the assignment because of his experience. Since Arthur is the design expert of the group, he will work on the “Component Form” of the writing assignment. Dave Nowak will continue his role of looking forward at the next gate and think of some the design changes we would make, but will also assist in the writing of this gate by taking care of the “Manufacturing Methods” section.

Table 2.B.III.A – This table shows the meeting schedule, including date, time and location, and meeting purpose for Gate 4 of the project.

For the fourth gate we must reassemble the unit and begin to apply our engineering knowledge and discuss how the drill operates and how we would improve it. Our first meeting will begin with our usual discussion of how we thought we did on the previous gate. We will conclude the meeting by looking at the Gate 4 deliverables and developing an outline for the gate. This meeting is one the 13th of November. The following Monday we will begin the reassembly of the unit which is require by the gate. This will be completed on the 20th and will be followed by the assignment of personal responsibilities for the written deliverables. We will work on these over the following week. We will only have one day to review the rough draft (the 26th) because that week is Fall Break. The group will make any changes necessary and have a quick meeting on December 1st to finalize the Wiki for submission. We will also make sure we have discussed our Grade on Gate 3 of the project and make any adjustments necessary to this.

Gate 4 involves the reassembly of our drill and the development of a technical manual of instructions on how to complete this. Since Matt Barker has experience doing this, he will be the lead on this and work on the deliverable portion of the reassembly. The whole group will assist in the actual reassembly. Mike Mason will continue his work on the “Cause for Corrective Action” because of his role as group leader. He will also work on the “Mechanism” portion of the paper Since we must identify at least 3 design revisions, the rest of the group will each be assigned one of these. Dave will also continue to work on his revision to the previous gates.

Table 2.B.IV.A – This table shows the meeting schedule, including date, time and location, and meeting purpose for Gate 5 of the project.

The final deliverables for the project involve a technical report and an oral presentation. With only a week and a half between the submission of Gate 4 and the submission of the final gate, we must work quickly to finish it completely. Our first meeting will be the 3rd of December and our group will create an outline for the final technical report as well as begin working on our oral report. We will continue working on these two items the next day. After this meeting we will assign out any additional work that needs to be done. On the tenth of December we will meet again and finalize the oral presentation and review the rough draft of the technical report. We will practice the oral presentation during the meeting the following day and finalize our technical report, so we are able to submit/present everything on the thirteenth.

This technical report and oral presentation will involve all of the group roles. Each person will be expected to pull their weight as well as help other group members improve the areas they have worked on. While we will probably divide up the report and presentation among the group, it makes the most sense for our group to work together to ensure they are as complete as possible.

Plan for Group Conflicts

In order for the project to be completed in the quickest and most complete manner, our group must work as a cohesive unit. This will not happen if the group is divided by arguments. The best way to prevent arguments within the group is for each member of the group to understand exactly what their responsibilities are within the group. In the previous section the group has developed a clear list of responsibilities for each group on a very specific time line. We have also allocated meeting time to discuss our previous gates. This will allow us to air out any grievance the group had with the way the previous gate was completed. However, sometimes the worst can occur and arguments can become emotional or a group member is consistently not pulling their weight. These can become a real detriment to the group. If this becomes the case the group will go to the instructors during their office hours with the timeline and list of responsibilities we have created. Using these we will discuss what the best solution is for the issue our group is having.

Product Archaeology: Preparation and Initial Assessment

Development Profile

This product does not have a specific date that it was developed as is it part of the D10 series, and there have been various updates to the drills as the series has progressed. But the most current version of this drill was produced within the past calendar year. The economic concerns of the time coincide with the current economic concerns of today. The pricing versus capabilities for the tool is based on the recession, as $44.00 isn’t a ridiculous price to pay for a professional style drill. And of course energy consumption is a large concern as well, but there’s not too much that a drill can do to change its energy intake while still maintaining its power. The largest environmental impact Hitachi could make with this drill is the fact that it is corded, so it will only draw power when it is in use. As far as its geographic market, this drill was intended for North American use, as the plug at the end of the cord works specifically in North American outlets. However, Hitachi is a Japanese company that sells a multitude of products to a myriad of countries, and there are probably many different types of similar drills that can be sold across the globe. Overall, Hitachi intended this drill to impact its consumers by providing a professional-style drill at a reasonable price.

Usage Profile

Hitachi intended professionals to use this drill as it has some extra features that you generally wouldn't see on a household drill. For example, it has the option to purchase a side handle so one could provide extra force when boring holes. Also on sites such as Amazon, there is an option to buy a pack of five drills. This is another clear indicator that it is intended for professional use, as an average homeowner wouldn’t need five of these drills. The D10VH is relatively diverse in the jobs it can perform considering the price. It ranges in speeds from 0 to 2500 rpm, which can accomplish tasks such as boring at higher speeds, and drilling at lower speeds. When purchasing this drill, a set of boring drill bits are also included. This is Hitachi again designating the D10VH’s capabilities. Separate from its drilling benefits, there is a convenient speed dial on the trigger as well, allowing the user to choose any speed within its range. Another accessibility advantage the drill features is a lock on the handle that will allow the user to keep the drill on without worrying about holding the trigger. And the D10VH drill only weighs 3.1 lb, which is a lightweight benefit over its cordless competition. All of these features are capabilities that professionals would look for in a drill. And because of professional needs, Hitachi was intending this drill to be capable of a diverse set of tasks while still maintaining an aspect of maneuverability, convenience, and ease of use.

Energy Profile

The Hitachi D10VH 6 amp 3/8-Inch Corded Drill is driven directly by electrical energy. It requires power from a standard single phase 120V 60 Hz AC outlet. The power is supplied through an 8ft cord and only interrupted before the motor by a trigger switch. The 6 Amp input is enough to power the drill to 2500 RPM unloaded. Corded drills are always rated in Amps versus cordless drills in Volts. The transfer of this current is very simple. The 120V is gained from the AC outlet, and is transferred to the motor of the drill when the trigger, acting as a switch is pressed. The motor transfers the torque created by the motor to the drill chuck through a clutch and thus spinning the drill bit. The clutch is necessary for the variable speed function of the drill. A corded drill is able to operate at the same power at all times when connected to a power source, which is why a corded drill is rated in Amps instead of Volts. In this system, the drill converts electrical energy to mechanical energy. Some energy is lost as heat energy, mostly from friction under load, reducing the efficiency of the drill. There are also fractional losses in the motor and other components of the drill. The corded drill has a significant advantage over the cordless drill in that its life of operation is limited only to the motor, where a cordless drill relies on the battery. A cordless drill will also become less powerful as the battery dies.


User Interaction Profile

The corded drill is very universal in design. This makes it very easy to use, regardless of past experience with any one specific drill. The Hitachi D10VH is no exception. It has a standard drill body with a pistol grip and trigger design. It has a comfortable form fit palm grip that is not specifically shaped for any one size hand. At 3.1 lbs, the drill is relatively lightweight and easy to handle. It has a keyless chuck that is easy enough to open close for someone who may have weaker hands. Another user-friendly perk of this drill is the locking trigger so a person does not need to hold down the trigger to continue drilling. It is a conveniently placed switch that is easy to engage/ disengage on demand. It also has ample torque for the size and price making it very useful for high speed applications. The variable speed dial makes it user-friendly for different people. The motor casing is a slight problem with this drill. The drill is short in overall length and the motor housing, relatively long, and large as well. It would get in the way in many tight areas where the drill might need to reach into a gap. This drill, like other corded drills, has the advantage of being low-maintenance for a power tool. The only inspection required is to inspect the drill bit to be sure it is not dull as that can create increased strain and wear on the motor as well as checking that all screws on the drills casing are fully tightened. As a precaution, the drill should be stored in a dry place and contact of the motor with any oil or water should be protected against In comparison, a cordless drill has the additional servicing of the battery, which needs charging and eventual replacement. “All quality power tools will eventually require servicing or replacement of parts because of wear from normal use”, states the owner’s manual. Regular maintenance drill rotating assembly is not necessary and not recommended.

=Complexity Profile

In this product there are many different components. There are some very important parts that do more for the functionality of the drill verse some that aren’t as important but you still need to allow the drill to run properly. Without taking the drill apart we were able to come up with 13 key components that are in the drill that allow it to run as designed. The first is the chuck (1) of the drill which holds the bits that the customer wishes to use with the drill. The second is a shaft (2) that is attached to the chuck with some sort of bearing (3) around it to allow it to spin freely against the housing. This shaft will have to have some type of gear (4) attached to it that will be attached to another gear (5) that comes off of the 120 V motor (6) that will be the main component that will make the bit in the end spin. Besides for the chuck, all of this will be in the outside housing (7) of the drill. Coming out of the housing will be a power cord (8) that will provide electricity for the motor to spin from a plug (9) that will be inserted into a wall outlet. Now there are four parts on the outside of the house that let the user control how the drill works as needed. One is the main switch (10) that tells the motor when to spin along with a lock button (11) that will lock the motor on when the user wants it to keep spinning without having to hold down the trigger. Then there is a revers/forward switch (12) with tells the drill what way the user wants it to spin along with a spinning knob (13) located on the trigger to tell the drill the intensity that the user wants the drill to spin with.

Each of these components has a particular attribute that it brings to the full set up of the drill. Each one is complex for the individual component but compared to the whole drill it is just one task that makes the whole thing work.

When combining these individual components it creates a relatively large amount of interactions between one another. With this many interactions it becomes more complex of a system. If one of these interactions doesn’t work correctly all of their interactions mat not work as they were designed and then the drill will not work properly.

Material Profile

There aren’t many visible materials in this product because a lot of the components that make it work are located on the inside of the housing of this product. Therefore for the visible components there is mostly hard plastic. There is also some type of rubber located along the back of the drill housing probably for some comfort of the user while using the drill. There is some visible metal at the end of the chuck where the bits are held. This is metal because this part is spinning with high speeds against some high forces acting in the opposite direction. So if this was not metal it may where out very quickly and not be able to hold a bit like it should any longer. There are also some screws holding the housing together and the heads of these screws are visible. These screws are made of metal also.

Besides these visible materials there are many non-visible materials. These materials are what make up a lot of the main components that make the product work like it is designed to. Our guess is that most of these materials are made of some type of metal because if it was made of plastic or some other material it may break or wear away quicker and then the drill will not work or the owner will have to replace the part that is no longer working like it should. The type of metal though is unclear due to the fact that there are many different types of metals out there. We also do not know what the producer of the product was looking for in the material they choose while they were designing the components.


Alternative Profile

The electric drill has had many improvements throughout the ages. Although the drill is usually the first choice for many people, there are many alternatives that can be used. From the very first drill being used by the Mayans to a drill being used on a different planet. Some alternatives consist of the eggbeater drill, push drill, bow drill, hammer drill, drill press, and the cordless electric drill, just to name a few. However, just within the electric drill category, there are many alternatives. The electric drill can be made from many different manufactures and can come in many different shapes and sizes.

All of these alternatives have their advantages and disadvantages. The eggbeater drill used different gearing ratios for fast and slow drilling. The fast ratio was used to drill holes and the slow ratio was used for torque. The advantages of using this type of drill is that it can be used with anything from a sewing needle size screw, to anything with a 3/8th of an inch chuck. Lastly, the eggbeater drill will never have a dead battery, like a cordless electric drill. The disadvantages of this drill is that it is very outdated. Also, the drill can make a person very tired. The drill depends upon a person’s strength and stamina. If there are many holes to be drill, a person can become tired very quickly (Dematto, Amanda, “Ultimate Garage: The 7 Most Extreme Man Caves”, Popular Mechanics, Web, 10/6/13).

A hammer drill also has many advantages and disadvantages when compared to an electric drill. A hammer drill is used for masonry and concrete work. The hammer drill allows a person to put much more force onto the drill, due to there being a handle on the drill. The hammer drill also delivers much more torque, allowing for easier drilling. However, the hammer drill does come with some disadvantages. One disadvantage is that it is much heavier than a standard electric drill. The hammer drill is also much larger, not allowing it to be used in small places (Braeuner, Shellie, “The History of the Hammer Drill, eHow, Web, 10/5/13).

All of these product alternatives have differences. A hammer drill, drill press, cordless drill, and use electricity in one form or another. While the eggbeater drill, push drill, and bow drill where all made before the invention of electricity. The eggbeater drill, bow drill, and push drill were all originally made of wood while the hammer drill, drill press, and cordless drill all have a form of metal and plastic in them. The different product alternatives all differ in size, weight, what they are best used for, how they are used, and what material they are used on. For example, the hammer drill is mostly used with masonry and concrete while a push drill is mainly used on wood. An example of how these drills are used differently is that a drill press is a standing machine. There is a lever on the side of the drill press that will move a drill bit up and down on a stand, allowing a person to drill holes through an object. A push is also used to drill holes, but in a much different way. The push drill is used either horizontally or vertically, and the drill must be pushed in order for the drill bit to move. Each push on the drill will cause the drill bit to move (“Drilling Holes with a Push Drill”, List of Tools, Web, 10/6/13). Today, these products can also differ by if they are still currently being used. The eggbeater drill, bow drill, and push drill have all but almost disappeared from being used today. The most common alternatives to an electric drill today are the hammer drill, drill press, and the cordless drill. Lastly, there is a cost difference between each product. An eggbeater in today’s market can cost as low as $4.00. While a drill press can push thousands of dollars. The push drill and bow drill can range in prices from $15 and up. The hammer rill and cordless drill can range from $50 and up. All of the prices of each product depend upon the quality, make, model, accessories, and warranty.

The use of an alternative product ranges from what it is being used for. A hammer drill will be used with masonry or concrete work. A push drill can be used in tight spaces that an electric drill cannot fit into. A drill pressed is used in most shops for accurate machining. The eggbeater drill and bow drill are not used to this date. They were both outdated when electric drills come about. When the work of several workers can be done with one worker with an electric drill rather than an eggbeater drill or bow drill, they become outdated.

Each product was influenced by global, social, environmental, and economic (GSEE) influences. If an area was unpleased by the GSEE factors, they would turn to an alternative product. An electric drill could have harmful byproducts to the environment, making people want a different product. Alternatives such as the push drill, and eggbeater drill have no harmful byproducts that would harm the environment. If the electric drill was not strong enough, and could not drill through all the materials needed by a certain company, they would choose an alternative. The company could choose the hammer drill or drill press because they both deliver more torque and power. A global factor of the electric is the amount of power needed to run the drill and what type of plug is on the cord. The plug may work in one part of the world, and not another. That part of the world would render the drill useless and go to an alternative product.
