8.2. Identify any potential hazards in the proposed design, e.g., changes that may occur during the useful lifetime
Faulty electrical connections due to mechanical vibration could cause fires or overheating.
Sensors become less sensitive over time and can lead to overheating.
Material other than PET or contaminated PET is added to the shredder causing the shredder or extruder tip to clog or damage the material properties of the filament.
9.2. Provide solutions to eliminate hazards identified in Assignment 8.2, e.g., changes that may occur during the useful lifetime
Add reinforcement of electrical connections that will be under the most stress.
Ensure that sensors are properly calibrated before each use and can be easily replaced after their useful life is reached.
Add warning labels to make sure the user only adds cleaned PET to the shredder and prompt the user via mobile application to confirm the source material.
