Element G: Computational modeling and concept assembly (M6)
Phase 3 of the design process for our Rube Goldberg subassemblies focuses on taking the most promising concept from Phase 2 and iterating upon it, prototyping it, and running simulations to determine it's effectiveness.
More specifically for Element G, this means modeling concept 2.3.2 in a CAD software. I elected to use Siemens NX for this process. The resulting A revision models can be seen directly below as engineering drawings, as well as their bill of materials with links to purchase stock components.
Final concept iteration:
I have elected to proceed with a modified version of concept 2.3.2, integrating classmate feedback on previous designs. My input of falling arm will trigger a pressure sensor, activating an electric motor. This motor turns a small gear, which meshes with a large gear, which is linked via a coupling rod to a freely rotating disc. This coupling rod rotates in a circle, at a fixed angle. This rotation moves the right stair, lifting a ball one step at a time. When the ball reaches the top, it falls onto a lever, the opposite side of which pushes up a tab connected to a suspended hammer. When the tab is dislodged, the hammer falls, which is my output function.
