Task: Door Hinges and Latches on a 3D Printed Vehicle
Description: We need to have ingress/egress points in the vehicle, but doors are some of the more complicated portions of a car. We need your help with a solution that handles the structural, functional and fitment elements required of any vehicle door.
Challenges to overcome:
1. Doors may have to house equipment and systems for controls, latching mechanisms (if latch is on the door side) and windows.
2. If conventional latching mechanisms are used, we need to understand how they can be securely mounted to 3D printed material so that they withstand high forces from impact, attempted theft and the impact of the occupants.
3. Door hinges, and latches are required to pass FMVSS 206, which states that each door must use a two-stage latch, and be able to resist the loads specified: 2500/1000lb longitudinally, 2000/1000lb transversely. Each door hinge should conform to SAE J934.
4. Doors and panels should be able to be adjusted for fit or the process should provide an extremely reliable accuracy of positioning to ensure proper aesthetic surface alignment.
Please provide your approaches to create the best system for ingress/egress on a 3D printed vehicle. We don’t need all the models and assets created; we simply need your best ideas. Please include the following:
o A general description of the system mechanism and approach
o A short description of hurdles addressed
o Links to any supporting info
o Links or leads to any specialized materials or equipment that are core to the solution
o Any diagrams that could assist in the understanding of the process solution
