Rotary Latch

Cars typically use two-stage latch, as it provides safety to “false” latching, meaning that it prevents the event of accidentally opening or not completely closing a door.

The double rotor provides more tolerance to misalignment and can withstand greater loading than the single rotor.

Handle

Functional Requirements:

• Allow the opening of the door

• Flushed with the surface for aero efficiency

Non-functional requirements:

• Aesthetically pleasing

• Easy to access and use

• Easy to manufacture

• Good durability

Constraints:

• Dimensions already defined

Concept Design:

1. Handle Design

2. Handle Cover

Spring Mechanism:

Functional Requirements:

• Allow for easy access to and operation of the interior handle / latch

• Should not touch seats or other components of the car

• Should not interfere with opening/closing of door

• Lightweight: should not be too heavy for hinges to handle

Non-functional requirements:

• Aesthetically pleasing

• Easy to manufacture

• Should not cause injury if bumped against (want rounded edges, soft material)

There’s a surprising amount of youtube video of people diy-ing their own door panels

Materials

• PVC foamboard and ABS plastic sheets seem to be the most common materials

List of benefits of PVC foamboard

1. is completely waterproof.

2. is easily cut, shaped, drilled, and sanded with regular wood working tools, and there are no splinters.

3. is easily stapled, accepts contact adhesive with no problems, can be heat formed, sewed, and glued together.

4. will never warp, rot, or absorb liquids.

5. is completely smooth, and tough enough to allow you to install and remove your panels numerous times with no problems.

6. is lightweight (1/2 the weight of solid PVC and 2/3 the weight of ABS)

7. is less expensive than solid PVC and ABS. One $30 sheet of PVC foamboard should do your door panels and kick panels, which also makes it less expensive than waterproof panel board and about the same price as good quality luan plywood.
