I wonder if a combined handle is possible: when you pull, the signal is sent _and_ mechanical 3-second delay starts. If the power is present, small solenoid blocks mechanical mechanism and door opens regularly. If it's dead, in 3 seconds door os overriden.
Or even easier: pull normally for electric release, pull real hard for override.

- rsynnott 1y agoThis feels like overthinking it a bit. Just _have a proper door handle like every car had had for about a century_.
- adastra22 1y agoMechanical time delay? How do you expect that to work?
- theamk 1y agoI can think of at least two methods right off top of my head: - centrifugal governor, as used in old-school rotary phone dials (this could be too fragile though) - an air cylinder with a small hole, as used in mechanical typewriters and vehicle shocks. I am sure a real MechE can can come up with even more methods.
- adastra22 1y agoBoth of these (and any other contraption I can think of) are not the kind of thing you want to include in a safety feature, which needs to be operable after the car has been in a crash, flipped over, door crushed, etc.
