System-Wide Approach

Design, analysis, testing, and manufacturing must work together. They all need to align for a clear path forward. This is a system-wide approach, viewing engineering tasks from many angles.

I have experience in all these areas. I can check product development and address current product issues from every angle.

Filling a Need

Every engineering task begins with a need. This could be a new product, a redesign, or transitioning an existing product. It might involve going from concept to prototype. Then, it can shift from prototype to short run. Finally, it could move from short run to full production. Changes might involve different materials or new ways to make things. For example, you could switch from machined parts to molded ones. Sometimes, new tasks arise due to field failures.

A simple flow might look like this: Marketing spots a need. Then, marketing and engineering discuss a path forward. A rough design forms. Next, trade studies start, followed by design analysis, including classical methods and FEA. This leads to prototype building and testing.

Simplicity is Best

Throughout the process, the designer should aim for simplicity. It’s important to ensure that no one discipline overshadows the others. External factors may complicate the initial need. Every area of expertise should play a role in the final design. This leads to a balanced solution. Ultimately, the design must undergo a review that maintains impartiality and rigor.

Design, analysis, testing, and manufacturing should work together as one unit, not as separate parts.
