Gate 1 - Project Planning

Project Management

This section will explain how we expect to dissect our Punisher Dart Gun. It will also discuss what we will need to dissect it along, including tools, documentation devices and a work schedule. We will also describe the group members and their capabilities and weaknesses.

Work Proposal

Equipment

• Screw Drivers:

We expect that we will need multiple sized Philips Head Screw Drivers to dissect our product. We expect to find smaller screws on the internal components than on the outside holding the plastic covering together.

• Pry-Bar:

We will have a small pry-bar handy in case we come across any components that are snapped in place and cannot be easily pulled apart by hand.

• Needle-Nose Pliers:

We expect to small part inside of our product which will need to be disassembled.

• Camera:

We will have a camera handy at all steps of the dissection process so that we can document what we do as we do it. We will take stills of the product step-by-step from beginning to end. We will also take videos throughout as we dissect the Punisher to better show how different components were installed.

• Laptop:

We will record on the computer what we did in each step of the dissection process.

• Safety Glasses:

We will be wearing safety glasses at all times to insure our safety.

Procedure

1. We will begin by removing the breach (ammo box) by unsnapping it from the rest of the Punisher.

2. We will then unscrew all of the screws holding the outer shell together.

3. We will then remove the internal components as it becomes possible.

4. We will also dissect the ammo belt and ammo box.

• We are unsure of what exactly we will have to do as we have not yet seen how the inside of the Punisher is constructed and assembled.

Management Proposal

Our plan is to meet in an open lounge in Griener every Sunday evening to assess what needs to be done during the week. The Project manager will take everything discussed at the meeting and come up with the week’s full planner. If further meeting is needed then he will set up a further meeting point on Monday or Wednesday following the lecture; all of the member of the team are free at this time. The dissection will take place in the 621` Furnas hall and the times will be later determined by the project manager and distributed by the communication liaison. Group conflicts will be solved by the communications liaison, if he is involved or cannot solve the issue then it will be brought to the project manager.

Product Archeology

Development Profile:

The product was first developed and sold in 2010. The total public and private debt was $50.2 trillion at the end of the first quarter of 2010, or 3.5 times GDP in the United States. In 2010 the economy was hit with a significant economic downturn making extra spending cash for toys uncommon. The product was designed for Western Culture, mostly the United States and Europe, and was created so that children can simulate the excitement of guns in a safe, harmless manor. The gun is designed with bright colors and obscure shapes so that it does not resemble, or encourage the use of real guns.

2010 Components of US debt, retrieved July 3, 2010

Usage profile:

The Buzz Bee Punisher Dart Blaster is intended for the entertainment of children ages five and up. Being able to fire 30 darts in 20 seconds, this motorized Nerf gun allows the buyer to get a realistic feel of a powerful yet long range gun. The Buzz Bee Punisher Dart Blaster is made so that anyone can use this product for entertainment in the home or outdoors.

Energy profile:

Chemical, electrical, and mechanical energy is used in the dart gun system. All energy that comes into the system comes from the 6 D batteries in the form of chemical energy. These batteries convert chemical energy into electrical energy, and the motor converts electrical energy into mechanical energy.

Complexity profile:

There are multiple motors, springs, gears, levers and electronics which make up the Buzz bee blaster. Breaking down each system, there are multiple motors which spin the barrels, feed the belt and load the spring of the Nerf gun. The electronics within this model like the battery pack, switches and electronic motors, will provide the necessary power to create motion in other motors. The springs which are powered by a motor, load the darts by compression and shoot the darts by expansion. Without gears in this system which change the speed of the motors and rotates the barrel, the firing process would not take place. The leaver or trigger combined with the use of electronics enables this Nerf gun to fire 30 bullets in 20 seconds.

Material profile:

When observed from the outside polyurethane foam material, and hard plastic can be seen. The darts are composed of the composite foam material, and the frame is made from the hard plastic. Inside the product there is likely metal screws, electrical wires, and the DC motor components. Each of these components can be broken down into smaller metal and plastic pieces.

User interaction profile:

Weighting 6.9 pounds the Punisher Dart Blaster is not the easiest to handle for younger children. Other than its weight the Punisher only requires a simple push of a button and then 30 bullets are fired in 20 seconds making this model easy to use. The only maintenance that is required would be to change the 6D batteries that power this gun. Minor breaks in its hard plastic can be fixed using duck tape while major damages like a breakage in the barrel may result in purchasing a new gun.

Product Alternative Profile:

The Punisher is just one of the many “toy” guns in society. Thus, there are many other products that are very similar to it and many have advantages and disadvantages when comparing it to the Punisher. Three examples of these toys include Air Soft guns, Paintball guns, and other Nerf guns.

Air Soft Guns:

   Advantages 
   - Shoot ammo fast and have a large range 
   - While still a toy, looks and feels like a real gun 
   - Can hold a large amount of ammo and reload times are fairly quick 
   Disadvantages 
   - Need a large area to actually use in, as gun has long range 
   - Pellets fired can actually break or damage property, so not safe for indoor use 
   - Pellets can potentially hurt other people, especially in areas of bare skin 
   - Guns are typically fairly expensive, and new ammo is also constantly needed 

Paintball Guns:

   Advantages 
   - Guns shoot ammo extremely fast 
   - Can be used in a competitive setting 
   - Feels like a real gun and can shoot extremely accurately. 
   Disadvantages 
   - Ammo/guns/equipment are all expensive 
   - Can be potentially very dangerous, if precautions not taken 
   - Needs to be used outside and in a designated area. 

Nerf Guns

   Advantages 
   - Safe to use indoors 
   - Safe for kids to use and play with (ages 6+) 
   - Guns range in price but most are not as expensive as other product alternatives 
   - Ammo can continuously be reused 
   Disadvantages 
   - Guns do not shoot as fast or as far as other products 
   - Does not give the feel of a real gun 
   - Not as effective outside as the power will not efficiently overcome any outside elements (wind, precipitation, etc...)
