5.2 Design Process:
Iterations:
For Prototype design:
Originally, we wanted to use the metal brackets given to support our slide shafts, but they proved too difficult to integrate into the part. Furthermore, other mount designs did not adjust correctly.
Many iterations of linkage were made to adjust the range.
This is one of the cam profiles that we tested to see its effects on the appearance of the jump.
The first design of the top mechanism was basic and added unnecessary weight.
We cut down the top mechanism to only use 2 linear rods at opposite corners to support the movement. This change allowed us to remove a majority of the material from the top box.
For the demo day, we constructed a mounting system to hold the mechanism out of carboard. This allowed us to fully preview our intended range of motion, while the more permanent solution was being designed in CAD.
Future Required Materials
Most of the parts needed for the “aesthetics” part (conveyor belt/background/interactive pieces) can be designed via a 3D printer; additionally, any future motor-related parts to this aesthetic part can be provided by the RMB bins. This being said, a better/stronger motor may need to be purchased to run our main mechanism.
