June Holiday Third Meeting

Today, we meet again to make the prototype with metal. This will be the real prototype for our projects day. After last meeting, we were more careful this time and more experienced. As such, we made the prototype with ease. We also started on the powerpoint slides.

June Holiday Second Meeting

Today, we did the prototype using plastic materials. It's just a mock up to familiarize ourselves. We meet with some problems like sawing and drilling holes. However, we got help from our neighbour who showed the correct and safe way to saw and drill holes. We finished making the plastic prototype and we bought materials for the next meeting.

June Holiday

Before the holidays, we meet with the expert mentor who gave us the suggestion above. We had decided to add one more pole below that creates two joints. This will ensure more safety as we do not have to lean our bodies over the window anymore.

Today, we meet at Tiet Gan's house to discuss and do the 3D sketches for our prototype. The pictures are all above. We also bought materials for the following meeting, which we would do the prototype.

Mentor meeting

Yesterday we met up with our mentor, she suggested that we should start on the building on the actual prototype so that we can start finding potential flaws earlier. She also suggested that we MUST have numbers to convince people that our project is workable. E.g. average weight of clothes pole, energy saved, etc.

We will calculate the figures as soon as possible

More pictures

This is our finished mockup prototype. It is still in its early stages and we are going to make a real prototype in the near future

The objective of this mockup is to show the concept of our prototype so that we can visualise it. also it gives us a chance to spot potential flaws in it.

A potential flaw would be the wear pivot, thus we have decided to upgrade into a high quality and heavy duty pivot. also the shock absorbing stopper is somewhat too soft and the poles cause it to droop down. We decided to change the material to hard rubber compound.

Our mentor also suggested that we should add a rubber lining at the tip of the housing to prevent cutting of the poles.

Building of a mockup for testing

We started building a mockup to test the principles of our invention.

Materials used:
Metal L shaped braces
Wooden Plank
PVC tubes
PVC glue
Screws

Total cost: $15

Idea concept

Final meeting

Today, our group meet up to finalise our project and also rehearse our slides. We thought of possible methods to improve our project too. We also consult our mentor to make any last minute changes.
