Prototyping

We used PVC pipes and connectors available in the lab to build a rough prototype simulating the structure and layout of our drying rack design.

 

Sketch of our prototype

Version 1:

• have a hinge at once side of the rack so that we can insert our clothes onto the rod without taking the poles out
• cons: putting a hinge will mean that one end of the poles will not be air tight and secured, so air can escape, which reduces efficiency
• using polycarbonate tubes to hang the clothes
• cons: polycarbonate does not conduct heat well

Version 2:

• instead of an hinge, we decided to follow the traditional bamboo pole hanging method so that our rods are easily removable and re-attachable
• use aluminum tubes instead of polycarbonate tubes so that heat is conducted faster from the heating element to the air
• the ends of the rods will be sealed using a rubber cap to create an air tight environment

Informal Presentation 1

• presented our clothes drying rack idea to prof
• suggestions and questions raised by prof

Purchasing materials

• purchased aluminum tubes, pc tubes (for frame) , centrifugal fan
