The discussion revolves around designing a portable pill crusher using a pneumatic cylinder, emphasizing the need for sufficient force to crush hard-shelled pills effectively. Users suggest that a combination of steady compressive force and rotational movement may be necessary, as simple compression alone has proven ineffective. The participant plans to utilize a compact pneumatic cylinder and a rotating base to achieve the desired results, while also considering the importance of time efficiency in the crushing process. Questions about the feasibility of pneumatic systems, portability, and the management of pill movement during operation are raised, highlighting the complexity of the design. Ultimately, the focus is on engineering a solution that balances force, speed, and practicality for crushing multiple pills at once.
