Problem Statement
Design and create a fixture to assist in the assembly of a fan-based product accessory. Bottom section needs to be constrained and elevated for ease of assembly, however fit should not be too tight to prevent damage to parts.
Process/Challenges
Process/Challenges
Began in Solidworks with model of the fan casing, created first prototype by offsetting the bottom surface to create a contour of the shape
First prototype was too tight a fit and over constrained the part, tolerances on the manufactured casing were low enough to cause significant fit differences
Created an adjustable contoured version, suffered similar issues
Moved to a more minimal design, supported the casing at the locations where pressure would be applied to the screws to minimize flipping tendency
After a feedback, added additional planes to better prevent a tendency to rotate
Finalized the design and created the fixture

Fan assembly fixture was used to assemble 50+ accessories for distribution to customers. The fixture reportedly made assembly quicker and easier.
