Hinges
Front door and back door space will limit amount of hinges and size as well:
Functional Requirements:
Must be able to support the weight of the door with minimal play
Must allow door to swing open up to 90° from the closed position
Non-Functional Requirements:
Designed for weight optimization
Ease of assembly
Low cost
High strength density (needs to take up less space)
Constraint Requirements:
Safety regulations
Follows rules of comp

Material Concepting
Hinges
Need strong materials, lightweight preferred
Steel (AISI 4140 or some other carbon steel)
Stainless Steel (304 or something similar)
Aluminum (6000/7000 series)
Manufacturing Concepting
Hinges
Custom made due to volume constraints
Similar design to ones used in real cars
Made using milling or sheet metal bending
Assembly Concepting
Hinges
Need 4 main components
Inner/outer hinge
Pin
Bushings (2 per pin)
Lock ring/retaining clip
Proof-of-Concept Testing
What sort of testing should we be doing to ensure our chosen materials/manufacturing processes/assembly methods will work on the end-product?
Could include ordering samples, testing fastening/joining methods, testing assembly procedures.
