Week 12 - Prototype Design & Construction (Gas Ignition)

The final proof of concept prototype that we require should demonstrate the ability for a gas stream to safely ignite from a nearby open flame through the use of a single mechanical control point. Once established we must the show how a circular array of flames can be ignited one by one and extinguished one by one. This proof of concept confirms that this is possible and can be implemented as part of the products interface.

 

Initial Sketch of the proof of concept model.

A quick demonstration of the trial and error that it took to achieve consistent flame ignition.

The final distance where gas ignition occurred quickly and consistently.

A side view ot the inital prototype utilising the pivoting wedge system.

I initially trialled the wedge ignition system however a lot of further divelopment is required to get this working effectively and for this proof of concept all that is required is that we show the controlled release of gas and it's ignition.

A modfied version of the pivoting wedge that demonstrates a controlled ignition and extinguishing of the flames. (See video and photos below for workings)

Top view of the proof of concept prototype.

Brief demonstration of the controlled ignition and extinguishing of the flames. (Note: The final product would use an electronic ignition system to ignite the first flame.)

The following is a series of shots that show the sequential ignition of the gas streams.

This proof of concept show how it is possible to control the ignition of multiple flames from a single control point. This can now be confidently implemented in the design.
