Meeting the CEO + Engineer

15/6/17

Had discussion with former CEO of the Sino-Singapore Tianjin Eco-city, Mr Goh Chye Boon

26/6/17

Met up with an engineer who agreed to help us in the instruction of our prototype

He had a different idea from us:

He wanted to crush the can vertically: No need for counterbalance + gravity works with the crushing force

He explained that the construction process was too dangerous for us to help with

We visited him every day after school to check on the construction and discuss the design with him

3D Model for consideration + more sketches

20/4/17

Created 3D model of the foot of the invention, a manual trapdoor and leg stands, with hooks to hang plastic bags




Sketches that have more detail of the mechanism (still a bit messy)

Online Meeting

15/4/17

Held an online meeting to discuss the prototype

- Narrowed scope to just cans instead of general trash (too general = compromising effectiveness?)
- First sketches of prototype:

Horizontal crushing mechanism operated by lever suggested in Prelims
Consider:
Trapdoor to manually pull out after can is crushed?
Material: 3-D Printed?

Preliminary Rounds: Feedback

5/4/17

Is the problem a lack of trash compactors, or is it an attitude issue

- Perhaps make the prototype more efficient to use

- Public education? (on packaging of product)

- Survey, more data gathering

- Check for more existing products: Home trash compactors

First Prototype Mechanism (cont'd)

24/3/17

I made a gif of the mechanism :D

First prototype: Mechanism

Basic Industries International 77703 Multi Crush Aluminum Can Crusher

The mechanism is simple and effective, so it could easily be used in the prototype.
