Design for Manufacture and Assembly (DFMA)

• INCLUDE AN 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.

Assembly

Assembly of the competitor's product is not the consumer's responsibility and occurs prior to the retail stages in the supply chain. The product requires tools and fasteners only where the piston chamber attaches to the base, and nearly all of the remaining interfaces are threaded. While minimizing toolage, this raises many challenges with orientation and radial symmetry where the assembly process could be made clearer. The variety of O-rings, springs, and cylinder diameters is another weakness that has room for improvement.

Due to the assembly process being deliberately separated from the consumer, ease of assembly is not a high priority and leaves room for redesign towards simplicity.

Design for Environment (DFE)

Design for Environment (DFE) can help bring focus to specific areas when improving a design. By analyzing the entire life cycle, the areas of the largest impact can be determined and minimized.

Production

Using the sporting and athletic goods manufacturing sector of EIO-LCA, we were able to estimate the environmental impact of producing the bike pump. The bike pump costs $50 today, which is about $39.04 in 2002. Power generation and supply has the largest contribution to the 613 mtCO2e per 1 million dollars spent in the sporting and athletic goods manufacturing category. Therefore we can estimate that for every bike pump produced 0.0239 mtCO2e is released into the environment, resulting in a minor $0.72 tax per pump.

Use

If the consumer purchases a bike pump, we can assume that they own at least one bike. Therefore we used the EIO-LCA Motorcycle, bicycle, and parts manufacturing sector to study the environmental impact of use of the pump. We estimated that today the average bike costs $300 which equates to about $234.27 in 2002. Our analysis approximated a small $3.82 tax per bike.
