Product Stakeholders
This is where we will identify major stakeholders (post-production) and list major product needs for each stakeholder.
Product Use Study
This is where we will document in detail how the product is used, step by step, and summarize findings from our user studies with photo documentation.
Product Mechanical Function
We will include some pretty diagrams and information about the mechanical function of our part.
Assembly
This is where we will have information/photo about the major assembly.
An exploded view of the floor bike pump will be inseted here... with all components labeled.
Sub-Assembly
We may need to include detailed sub-assembly photos and information here.
This is where we will insert exploded views of each internal sub-assembly with labeled components and a brief summary of each sub-assembly function.
Bill of Materials
The following is a bill of materials from the bike pump dissection. The parts can be sorted based on part number, quantity, weight or material by clicking on the appropriate tab at the top of the table.
Design for Manufacture and Assembly (DFMA)
- Introduction as to what DFMA is***
Manufacturing
The competitor product we analyzed displayed numerous positive manufacturing features that would minimize cost and complexity. The overall design is surprisingly simple, a result of combining features into single parts where possible, using only a few different materials, and minimizing the overall part count. (INSERT COMPONENT WITH BIGGEST ROOM FOR IMPROVEMENT AND WHY).
Below are some of the DFM Guidelines and the observations we made of how our competitor designed their product with those guidelines in mind and some areas we believe they could improve.
Positive DFM Features
Minimize Part Count
- Few fasteners, mostly everything screws together
- Many multifunctional components leading to less parts overall
Standardize Design Features
- The only screws in the system are all identical
Keep Designs Simple
- Piston shows a clever design to allow air into the pump on upstroke while eliminating lost air on downstroke, while still remaining very simple
Multifunctional Parts
- Many parts serve a specific purpose while also screwing into the next assembling acting as both a functional piece and connector
Ease of Fabrication
- Mostly composed of some type of plastic and steel.
Avoid Tight Tolerances
- Uses flexible rubber o-rings to allow for larger tolerances while remaining airtight
Suggested DFM Improvements
Standardize Components
- Since there are few fasteners, most parts are custom-made for this product
Keep Designs Simple
- Pressure gauge is very complex, needs fine adjustment and much protection
Ease of Fabrication
- The plastic parts are for the most part unique and would each need their own mold
Minimize Secondary & Finishing Operations
- Since parts are multifunctional, most would require at least would need a secondary threading operation
Assembly
The competitor product also exhibities many decisions that help simplify the assembly, including sub-assemblies, mistake-proof orientations, and low part count. However, there were some drawbacks we noticed, such as (INSERT DRAWBACKS). We found the biggest area for improvement was (INSERT AREA WITH BIGGEST ROOM FOR IMPROVEMENT AND WHY).
