This dissection is mainly focusing on technical engineering drafting; ball bearing is selected as the object to draw. We were first asked to disassemble the elements of the ball bearing and made measurements of each part ( inner/outer race, retainers, balls, shield). Then, I created three principle views of the ball bearing.
This dissection developed my ability to take key measurements with a caliper and use them to create technical engineering drawings, which are crucial skills for a product design engineer.

Modified screwdriver. A fail-safe safety knob was added such that when the red key is inserted into one of the 26 grooves on the ring gear, the gears are prevented from spinning and the on/off power switch is unable to be turned on.
The primary task of this dissection is to model the gear train inside the can-opener. The second part of the dissection is to modify the gearbox with a given real-life problem. The problem is quoted as below.
“Consumers have complained that the original, low-cost design jams too easily and thus cannot open some cans. Fix this problem by increasing the torque output of the gear train by 25% to 50%. The new design should be able to (roughly) fit within the same space and connect to the input and output at roughly the same locations."
This dissection honed my skills to make modifications based on existing designs in order to meet the specifications of a product.
