This project was started as part of the 2018 3D project for 30.001: Structures and Materials and 30.002: Circuits and Electronics
Goal: To design, build, and analyze a gadget/device/product for an application related to one or two of the EPD tracks using concepts obtained in 30.001 and 30.002. Students were encouraged to use discrete electronic components, MOSFETs, Op-amps, R, L, C, diodes, sensors, and logic chips, e.g. counters, shift registers. Students are discouraged from using embedded systems, e.g. Arduino or rely too heavily on coding.
Project timeframe: Term 4 week 5 to term 4 week 12
The tables currently available in the market are not suited to fit different user requirements simultaneously, such as the need for a standing desk for the more health-conscious or simply the need to adjust desk height to suit one’s needs. Currently, one has to use an entirely different table for a different purpose and it is inconvenient and costly for the user.
Currently in the market, it is ergonomic tables and desktop attachments are costly, hence a problem that we can tackle is the high cost of ergonomic tables. Our product, Alleviator, which could clamp most table leg sizes, makes any table ergonomic and can be used to elevate the tables to the appropriate height and angle of inclination.
The concept of our product hinges on the automation of the product’s folding and unfolding, which thereafter determines the height of the table. The automation is done through the implementation of a switch system. We chose carbon fiber, a material strong enough to maintain its rigidity under stress.
Laser cut file attached above is the file we used to make the clamp.
MOSFET used: NCE30H15
15V power source attached to MOSFET, 9V battery attached to motor.
Here we explain what the files in our repository do.
| File | Description | Comments |
|---|---|---|
| 3D_laser_print.dwg | Laser cutting file used for printing of clamp and drill guide for carbon fibre square tubes | AutoCAD is used to create file. The circular parts of the file are the clamp, rectangular parts are the drill guide. Parts are to be placed together using nuts and bolts. |
