In this week, the team was working on the project. the part of modelling out the system was emphasised. There were few thing that we need to be aware of such:
- The exact mechanism and prototype
- What would happen to the device when there is a black out.
What our idea was is the have a series of boxes lining into two rolls rotate into a rectangular round. Selected box will be stop at curtain position and move down to the user.
The primary design of the device is consisted of a few boxes that would be connected to a track. The problem of the design that we discussed were :
-The transition of the boxes involves up and down, sideward. What would be the force to move the box?
- If use the track, the box will not be able to transform from one trek to another with this position.
- What is going to hold the box onto the track?
At this stage we needed to do some more research of how would the mechanic for the device would work to satisfy the purpose of the use.
In the discussion we mention about the mechanic system in the vending machine and claw crane. This could be and alternative way to translate the box from one position to another.
I found this video on youtube that work similar to the vending machine, super-fast mini load.

Another video of the same idea. this video show the 'arm' that move to a curtain position and grab the box then bring it down for the user.

The problem of this design, it is not really a space restricted as the whole system would requite a big frame for the arm to be able to move a grab a box at particular position. It will requite a lot of space for installation of the system.
