This electric sharpener works with electricity directly plugged in. It seemed fairly simple at the beginning. I was not expecting that many pieces and screws. I could not open the battery, I guess they are glued together.
Process
Step 1:
- Separate all the pieces that do not need unscrewing.
- You have the pencil sharpener, the trash box and the wall charger.
Step 2:
- After separating all the pieces I took out the first 4 screws.
- The plastic parts where set aside and kept working on disarming the main engine.
Step 3:
- Remove the entire engine and pencil sharpener mechanical parts from its plastic container.
- At this point the sharpener still worked when plugged in.
Step 4:
- Remove the next 4 screws and separate the engine from its main structure.
- Inside their where 3 gears that moved consequently from the mains engine gear.
Step 5:
- Then I proceeded to remove the engine.
Step 6:
- Once the engine was removed, I separated all the gears, screws and plastic parts attached to it.
- Then I removed the pencil sharpener from the main cabin.
Step 7:
- Finally I got to the main engine. Took it apart until I could not anymore.
- It seemed fairly simple, coil and two magnets inside that made the main axis rotate when plugged in.
Step 8:
- Once completely separated it was time to put it back together, which I did and it was a lot of fun too.
Nice investigation, Sebastian! You might be the only student able to reassemble his/her teardown object. Please add to your post to fulfill the assignment, here are the things missing:
-Identify the materials used for each component
-Identify the manufacturing techniques/equipment used to make it
-Make a list of the tools and techniques you used to take it apart
-Select two design elements that interest you and describe why you think the designer made it that way
some dumb English stuff: Watch spelling on “their where” in step 4. Also when you write “engine” it is really a “motor.”
