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.
