Roof Propping Mechanism Design Sprint

Sprint Goals:

  • Design a simple roof propping mechanism that is capable of holding the roof panel at different angles during the competition

  • The roof must be capable of propping between 0 degrees - 90 degrees from the horizontal

  • The system must be self standing. That is, the prop must be setup and be capable of holding the roof up

  • The propping mechanism must stay within the aerobody at all times of the race (i.e. any prop rods, pins, telescoping poles need to find a home in the aerobody where they will be found)

Process:

  • Concept Sketches → Design → Manufacturing

Key Details:

The roof panel is tilted along the left side of the body. The tilting does not have a rotational limit and will rotate until geometry begins clashing. Please refer to the open roof in the position below. The roof is open at 90 degrees, but this is the most extreme case. Most times the roof is propped it will be below 90.

The most important aspects of this design are packaging with the pre-existing geometry, allotting space for any loose geometry to be added (if your design requires a rod of some sort, it needs a place to be mounted during driving), and ease of use.

The simpler the design the better (without giving up functionality).

Note that you will need to make your own development assembly in CAD once you’re ready to tackle on some CAD.
