As the handgun is best suited for firing projectiles with just the pull of the trigger, so is the paintball marker casing, which mimics the generic layout of the handgun; a hand-grip-friendly handle, a trigger located near the expected placement of the index(trigger-pulling) finger, and a single barrel that will contain ammunition and propulsion for that ammunition. This generic layout is intuitive to new users and very common to users with prior firearm/water gun experience. However, certain modifications are made to account for the fact that this is a paintball marker and requires different ammunition and sources of propulsion. The most apparent modifications are the diameter of barrel and chamber to accommodate the paintballs, and the method in which the ammunition is contained and fed, the hopper and feed elbow.</p> <br> |

| − | + | <p>From this information, the two halves of the casing continue this product’s theme of simple and straightforward components. In order to appeal to the masses and gain the reputation of a “standard” paintball gun, the 98 Custom’s main most apparent feature, the casing, mimicked many features of the standard handgun. However, after taking into account the necessity to scale this design to accommodate the function of firing paintball and remain an affordable marker, an aluminum alloy was used to make the casing rather than steel. A casing composed of this material would be cheaper yet still have enough durability and strength to manage the other components; steel could be used but the casing would be too difficult to handle, and if plastic was used it would be cheaper but sacrifice durability over the lifetime of the component. Apart from the physical properties of the casing, the visual aspects, specifically the shape of a firearm, is a constant reminder that the paintball marker can still cause injury and should not be misused; thus, the choosing the shape of a handgun will be a signal to the user and others that this is not a toy.</p> | |
<h5> Manufacturing Methods</h5> | <h5> Manufacturing Methods</h5> | ||
| + | With consideration to the apparent theme of simple and straightforward, constructing the casing out of almost identical halves and of a fairly affordable material would not cause any drastic sacrifices to the performance of the marker, and would provide ease of assembly/disassembly for the user. In order to support several components on the inside and outside, as well as to allow openings in various spots, the manufacturing method would need to abide these requirements in order to successfully create the casing. While machining and forging could be used, the much simpler method of die casting was used for each casing side. Die casting could easily and economically accommodate an aluminum alloy casing that would need to be relatively flat, simply curved, and require holes and openings in several spots. This method would produce dimensionally consistent component at an economical cost if they are mass produced.</p> | ||

Purpose
Gate 3 will provide a more detailed analysis of the Tippmann 98 Custom Paintball Marker by examining the product’s components more thoroughly and discussing their significance in relation to the product’s overall function and interaction between other components.
Coordination Review
Cause for Corrective Action
After Gate 2 was completed, Group 28 planned for Gate 3 by planning out what tasks needed to completed with the time that we had. The weeks preceding the deadline for Gate 3 had many time conflicts for group members, due to exams and time scheduled for studying. Thus, most of the group members opted to delay progress on Gate 3 material until after they had time to devote to it. The group decided to work on the weekend directly following exams; this decision was followed through with and a great majority of pre-wiki was completed. Though the group decided to allot their time towards studying for exams and such, most of the work for Gate 3 was accomplished for at the rescheduled time. Group 28 still had problems with working on the Gate in an orderly, efficient manner but still managed to devote an equal amount of time later on.
Nearing the deadline of Gate 3, the group has yet to discuss work on Gate 4 which will need to be addressed before the Fall break. If a plan for Gate 4 is not discussed prior to the break, there will only be less than a week to have to work on the Gate.

Product Analysis
Measuring Component Complexity
Component complexity is not normal unit that can be measured through normal means, so a scale measuring certain key features of each component will produce values that will provide a sense of the level of complexity.
A 0 – 3 point scale will be used for each feature:
- 0 – The component has none of this feature
- 1 – The component has very little of this feature
- 2 – The component has a moderate amount of this feature
- 3 – The component has a lot of this feature
And the Key Features being considered are:
- Material Composition Diversity: which takes into account how many different distinct materials (metals, polymers, wood, etc.) the component is composed of.
- Manufacturing Process: which takes into account how difficult or complex the process to make the component was.
- Energy Interaction: which takes notice of how often and to what magnitude the component interacts with forces and transfers of energy (gravity, changes in kinetic, potential, internal energy, non-atmospheric pressures, etc.)
- Geometry: which considers how abstract or uncommon the geometry of the component is. An ergonomic viewpoint may be considered, since complexity is related to how well the component geometry might suit the user.
- Component Mobility/Movability: which considers if the product moves unnaturally or is prone to being displaced for its normal position. This feature will also consider removability and the ability for the component to freely move on its own or if the user wishes it be moved.
- Component Interaction: which considers the interaction between sub-systems and other components. Obviously, the more interactions a component has the more varying factors and function are associated with it.
When all these features have being given a rating from the afore-mentioned scale, a weighted average will be taken to determine how complex the component is. Simply put, a smaller number will have less complexity (simplicity) and a larger number will be more complex (abstract).
The formula is determined by giving key features more contribution towards complexity than others:
Complexity(C) = 0.10(MCD) + 0.10(MP) + 0.25(EI) + 0.20(G) + 0.15(CMM) + 0.20(CI)
Each term is simply written as the first letter of each feature (Manufacturing Process = MP)
the highest obtainable score is 3 while the lowest is 0
Before analyzing all of these component, a general remark about the environment in which they function/ operate will be made: Every component discussed below operates in relatively same environment, which is any climate/weather or terrain a paintball match would be set in: ranging from snowy to dry and hot or rocky to grassy terrain. Even the components which are housed inside the paintball casing are susceptible to these environments, as the casing is not a well-sealed apparatus.
Hopper
Component Function
The hopper’s sole purpose is to feed paintballs into the paintball marker. This is achieved with the aid of gravity, which will cause paintballs to go downwards towards an opening at the bottom of the hopper, then through the feed elbow, and finally into the marker chamber. For this hopper in particular, the action of feeding the paintballs is not quite accurate, since gravity does all of the work and the hopper is mainly a containment unit; there are no additional forces which would force the paintballs down more efficiently or more quickly.
In order to fill the hopper with paintballs, the user has to simply pour the paintballs into the opening which is covered by fitted plastic lid that acts about a hinge.
Component Form
The hopper is in the shape of a “bean” and is composed of rigid, black plastic looks with the exception of the clear plastic lid.
Other notable dimensions/properties are:
- Symmetrical down its longest side (where it separates into halves)
- Two circular openings at the bottom (13/16 inches Diameter) and at the side facing towards the user (2.25 inches Diameter)
- Six screw wholes for the relevant screws to fasten the two identical halves together
- Average thickness of 3/32 inches
- Semi-matt surface finish on the outside and glossy, smooth finish on the inside
- Right halve weight – 2.36 oz; Left halve weight – 2.18 oz; Lid weight – 0.46 oz
- Average height of 3.5 inches (not including the bottom opening), Length of 8.5 inches, and Width of 3.5 inches
- ”MADE IN CHINA” mark on the outside in small print, the company logo on both sides, and several drafts on insides of halves
- Holds approximately 200 paintballs
- The bottom opening diameter is identical to the top opening of the Feed Elbow’s top diameter
From these observations, some information can be inferred about the consideration that went to the design of the hopper. The hopper is in general a lightweight, rigid plastic shell meant to simply hold one object. Also, the aesthetics of the hopper are not particularly amazing or impressive. With this in mind, the designers and engineers at 32 degrees (the manufacturer of this particular hopper) decided to build a universal, economical hopper that can be considered an industry standard for all paintball markers. With a price of approximately 4 US Dollars, the production of this hopper was meant to be simple, basic and straightforward to its purpose (feed paintballs); the unimpressive yet efficient design of this component is a reflection of that.
Manufacturing Methods
In order to produce a basic hopper at a very affordable price, the most economical choice was to create the hopper out of plastic, a very inexpensive material compared to metal or wood. And to form the plastic, the most economical method would be Injection Molding, which is economical for mass production. Also, the overall shape of the hopper is relatively simple, with no abrupt changes in curvature or finely detailed aesthetics, so the initial mold for the hopper would be cheaper to produce than one requiring a costlier mold for complex geometry. With only two halves that are almost identical and a flat and simple lid, the molds needed would not have to be extremely intricate nor require any additional R&D. Thus, the overall the design of this hopper is suited well to economic advantages of Injection Molding and was thusly designed around that concept.
Component Complexity
The component complexity can be considered accordingly :
- Material Composition Diversity: A rating of 1, since only a simple plastic of black or clear is used, and simple stainless steel screws are used.
- Manufacturing Process: A rating of 1, since Injection Molding of this degree is straightforward and relatively easily
- Energy Interaction: A rating of 2, since the component is completely reliant of gravity, as is the nature of a gravity-fed hopper
- Geometry: A rating of 2, since the design is simple in terms of production but abnormal compared to simple geometric figures (cylinders, rectangles, circles, etc.)
- Component Mobility/Movability: A rating of 2, since the component has a lid which will be repeatedly opened and shut, and the hopper is separate from the main body of the marker (actually a third party product), which actually makes this component completely removable if desired.
- Component Interaction: A rating of 1, since the only interaction is the Elbow Feed, which only consists of paintballs being fed through.
Applying the formula: Complexity = 0.10(1) + 0.10(1) + 0.25(2) + 0.20(2) + 0.15(2) + 0.20(1) = 1.6
Feed Elbow
Component Function
The Feed Elbow’s name is very revealing of its function, as it is an elbow joint which allows the feeding of paintballs. The bottom hopper is affixed to the top of the elbow joint, and the bottom/side is mounted on the side of the Custom Receiver (Right) via an impermanent hinge. The feed elbow is the intermediary step from the hopper to marker chamber, and simply directs the paintballs from the hopper to the chamber. The feed elbow is also restrained to the casing by the front sight which prevents the component from rotating about the hinge and away from the casing.
Component Form
The Elbow Feed is made of black plastic and has a few metal components that serve the only purpose of mounting it to the casing.
Other notable dimensions/properties are:
- An average thickness of 1/8 inch
- Weight of 1.79 oz
- Elbow bend of 40 degress
- Top opening diameter of 1 inch (not including thickness)/Side opening diameter of ¾ inch (not including thickness)
- Average Width of 1.75 inches, Total Height of 3 inches, and Height from top to bottom of side opening of 2.125 inches
- Draft marks and parting lines
- Semi-matt surface finish with no aesthetics
- Symmetrical down its front face with side opening facing forward
- The general geometry changes from an open cylinder at the top opening, into a elbow joint a third of the way down, and then an opening which fits the geometry of the side of the marker casing
From these observations, the Elbow feed is another straightforward component that only has the features necessary to perform its function. The simple, black and semi-matt plastic is a cheap and basic material that is very common, and serves the purpose of being cheap, economical, and consistent with the rest of the outside components of the marker. Though the people who designed this component were not from the same manufacturers as this component, the theme is still the same, simple and economic parts that perform their function without unnecessary actions.
Manufacturing Methods
Very similar to the Hopper, the Elbow Feed has been constructed with Injection Molding in mind, since the specifications needed to conform to the side of the casing and allow the transfer of paintballs does not have to be perfect, there can be some more for error. Injection molding will also have no impact on the performance of marker, but so would any other method of manufacturing, too; thus, there would be no reason to design an Elbow Feed with an intricate design and composed of extremely high quality material which might require a more complex manufacturing process.
Component Complexity
The component complexity can be considered accordingly :
- Material Composition Diversity: A rating of 2, since additional metal components are necessary to mount it to the casing. The primarily plastic component is reliant upon these metal fixtures
- Manufacturing Process:A rating of 1, since Injection Molding is a relatively simple process, and this mold would consist of only a single part
- Energy Interaction: A rating of 1, The component will only experience the weight of the Hopper and the impact of very light paintballs, which will have no effect (deformation or wearing) on the to the plastic its constructed of.
- Geometry:A rating of 2, since the geometry changes several times, yet is not too extreme or abstract.
- Component Mobility/Movability: A rating or 3, since the component has to rely on a hinge and be secured by the front sight. This component is also completely removable and can be considered optional by the user.
- Component Interaction: A rating of 2, since the component must interact directly with the Hopper and the chamber, but only contributes passively by allowing the paintballs to get from point a to b.
Applying the formula: Complexity = 0.10(2) + 0.10(1) + 0.25(1) + 0.20(2) + 0.15(3) + 0.20(2) = 1.8
Marker Casing (Custom Receiver Left & Right)
Component Function
Marker Casing’s primary function is to house the internal components, such as the valve and bolt sub-system, and act a device that can combine with external fixtures, such as the grips, barrel, tank adaptor, hopper, and elbow feed. Along with being the central fixture of the paintball marker, the casing is the primary means which allows the user to properly interact with the marker and the other components; when the other components are properly supported/constrained, the functions of those other components will perform as they should, since they were designed to operate with the casing.
Component Form
The most distinguishing trait about the casing is the similarity to a standard issue handgun. As the handgun is best suited for firing projectiles with just the pull of the trigger, so is the paintball marker casing, which mimics the generic layout of the handgun; a hand-grip-friendly handle, a trigger located near the expected placement of the index(trigger-pulling) finger, and a single barrel that will contain ammunition and propulsion for that ammunition. This generic layout is intuitive to new users and very common to users with prior firearm/water gun experience. However, certain modifications are made to account for the fact that this is a paintball marker and requires different ammunition and sources of propulsion. The most apparent modifications are the diameter of barrel and chamber to accommodate the paintballs, and the method in which the ammunition is contained and fed, the hopper and feed elbow.
Other notable features are:
- The casing is composed some type of aluminum alloy
- Height of the casing(excluding the front and back handle) – 2 inches/(including the handles) – 5.75 inches
- Length(excluding back handle) – 10.75 inches/(including back handle) – 11.25 inches
- Total Weight of casing – 23.51 oz / Left – 11.81 oz / Right – 11.70 oz Black painted, matte surface finish on the outsides, and no notable surface finish on the inside besides post-casting polishing to provide a smoother surface.
Notable differences between the right and left sides are:
| Custom Receiver Left | Custom Receiver Right |
|---|---|

From this information, the two halves of the casing continue this product’s theme of simple and straightforward components. In order to appeal to the masses and gain the reputation of a “standard” paintball gun, the 98 Custom’s main most apparent feature, the casing, mimicked many features of the standard handgun. However, after taking into account the necessity to scale this design to accommodate the function of firing paintball and remain an affordable marker, an aluminum alloy was used to make the casing rather than steel. A casing composed of this material would be cheaper yet still have enough durability and strength to manage the other components; steel could be used but the casing would be too difficult to handle, and if plastic was used it would be cheaper but sacrifice durability over the lifetime of the component. Apart from the physical properties of the casing, the visual aspects, specifically the shape of a firearm, is a constant reminder that the paintball marker can still cause injury and should not be misused; thus, the choosing the shape of a handgun will be a signal to the user and others that this is not a toy.
Manufacturing Methods
With consideration to the apparent theme of simple and straightforward, constructing the casing out of almost identical halves and of a fairly affordable material would not cause any drastic sacrifices to the performance of the marker, and would provide ease of assembly/disassembly for the user. In order to support several components on the inside and outside, as well as to allow openings in various spots, the manufacturing method would need to abide these requirements in order to successfully create the casing. While machining and forging could be used, the much simpler method of die casting was used for each casing side. Die casting could easily and economically accommodate an aluminum alloy casing that would need to be relatively flat, simply curved, and require holes and openings in several spots. This method would produce dimensionally consistent component at an economical cost if they are mass produced.</p>
Component Complexity
The component complexity can be considered accordingly :
- Material Composition Diversity: A rating of 0, since the casing halves are composed of a single material, which means there is no composition diversity.
- Manufacturing Process: A rating of 2, since the product required two separate molds for each casing halve, and then after the die casting, probably some post-processing to allows screws and bolts to fasten the two sides.
- Energy Interaction: At rating of 1, since the component when assembled with all other components, will not withstand any forces that may cause harm to it. When fastened together, the casing can be considered a solid, durable metal housing.
- Geometry: A rating of 3, since the profile of the casing halves is very exact and has every component fit within or on the casing. There is no definitive name of the geometric shape might be.
- Component Mobility/Movability: a rating of 0, since the component will not move or be displaced when fastened, with exclusion of the user moving the entire product.
- Component Interaction: A rating of 3, the component interacts with almost every component in the product, and many of the other products are completely reliant on the casing in order their function to be carried out.
Applying the formula: Complexity = 0.10(0) + 0.10(2) + 0.25(1) + 0.20(3) + 0.15(0) + 0.20(3) = 1.65
Rear Bolt & Rear Bolt Plug
Component Function
The Rear Bolt and the Rear Bolt Plug coincide with each and rely on each other to perform their overall function: which provides the firing force to actuate the valve and release the pressurized gas. While this is the overall function of both these components combined, the Rear Bolt and Plug have several other functions they are responsible separate from each other.
