Assembly Diagrams

  • Include pictures of the assembly with all components labeled

Mechanical Function

  • Document how the system functions mechanically

Design for Manufacturing and Assembly (DFMA)

  • Highlight findings and opportunities for improvement, indentifying where our competitor has followed guidelines and made good choices.
  • In particular, are there opportunities to improve manufacturability and make a competing product cheaper? Identify where material and process choices are appropriate or inappropriate for expected production volume.

Failure Modes and Effects Analysis (FMEA)

  • Highlight findings and opportunities for improvement, indentifying where our competitor has followed guidelines and made good choices.
  • In particular, are there important failure modes that should be considered in a redesign or a new design? Focus on use phase, rather than manufacturing.

Design for Environment (DFE)

  • Highlight findings and opportunities for improvement, indentifying where our competitor has followed guidelines and made good choices.
  • In particular, if Congress were to pass a tax on CO2, would this have a significant impact on the cost of production or use of the product?

Mechanical Analysis

  • Include mechanical analysis to support quantitative understanding of the product's most critical mechanical aspects. Indluce a free body diagram, and be sure to define all symbols and explain all equations used.

Team Member Roles

  • Identify team member roles during this phase and summarize your process. Submit individual peer evaluations to Prof.
