The design


The main focus of the design was to give the users different heating options and locations. The product looks at having 3 central devices; a heated blanket, a heated gel pad and slippers.


This heats all the core areas that users mostly commonly feel more susceptible to cold. The internal tray can be replaced to allow users to customise their unit to fit many different devices of their choosing. The simple screen interface allows the users to set the controls to their own preferences. However there is a function that turns the unit on to Automatic mode. This detects any changes in the room temperature, and will adjust accordingly. The system will begin to self heat and will give an audio and visual signal to inform users that there is a temperature drop and action is required. The controls have been designed to be easily understood by the intended users, to give them the confidence in using the product

Working Prototpyes ​

Below is an example of the working prototype I gave to users to test. The circuit boards looked at finding the most efficient shape of the coil. From the findings it showed that a tightly wound coil was the most effective at conducting heat. 

This test proves that an induction heating system for small residual heat retention devices, will work well for short heating cycles and produce the necessary heat required. Shows that a cycle of heating ( at 7 Amps x 240V = 1680 Watts ) for less than 5 minutes per 20 min re-heat cycle, is substantially less than a space heater running for the same period.
