Gate 1

Work Proposal


Before any dissection occurs the device should be unplugged and should remain this way throughout disassembly and assembly.

  1. The lever and blade component of the can opener is easily detachable (without the use of any tools) for the purpose of consumer cleaning. This component should then be removed first.
  2. Next, the plastic covering needs to be removed in order to access the inner components of the can opener.
  3. If any electrical wiring is detachable from the motor, it should then be detached and the motor should be removed. If not, the motor should be removed from the system along with the electrical wiring.
  4. The gear system and any remaining workings should then be separated and removed.

All components of the can opener should be separated appropriately into bags or containers, labeled, and organized and each significant step of disassembly should be recorded.


Assorted mechanical screw drivers and wrenches should be the only tools needed for the disassembly. The assembly should mirror the disassembly and therefore only need the same tools.


The disassembly should not be too challenging, but it will be tedious and therefore might take a couple hours. The reassembly will take significantly longer than the disassembly due to the inherent nature of creating versus destroying. There may be some small intricate parts in the inner workings of the device as well as condensed components which make it difficult to reach the necessary parts. Therefore, this might present some challenges and delay the disassembly process. There should not be any complex circuitry so electrical aspects should not be a challenge.

In this group, we all have a basic understanding of dissecting a simple device by using logic, prior knowledge of engineering concepts such as gear workings. We all also are capable of using the simple tools that will be necessary to dissect this device. The biggest shortcoming we may encounter is organization and communication. In order to sufficiently dissect the device our group must be cautious in disassembling the device, make sure to record all progress and difficulties, and organize each dissected component appropriately. We also need to make sure to do any research necessary to better understand the systems such as the gears and motor that is implemented in the can opener.
