Universal Power Windows and Doors

With the superiority of the Bowden Power Windows it is surprising that there is no universal power windows. Instead a Double Bowden is introduced.

Proton Wira uses the Bowden Power Windows for both front and rear windows. Unfortunately, the rear power windows is different from the front one. Which means that a new power windows regulator need to be designed for the rear windows, instead of designing the rear door to accommodate the front power windows.

It increases cost with little advantage to show for it. The increase in cost may be small, but it all adds up. Sandy Munro would be unhappy for any lost opportunity to reduce costs. Surprisingly, I haven't seen any teardown of a power windows system in Munro Live.

Subsequent generations of Proton Power Windows uses the more complex and troublesome Double Bowden. It has two smaller pillars increasing costs with little to show for it. The total size of the window support is still the same. It also assumes that the centre of gravity of the glass is exactly at the centre, which is never the case. It means that there is an imbalance in the forces to the support pads.

I shall support the Proton Wira Front Right and Left as universal power windows. We should design the doors to fit these universal parts, rather than having to redesign both the doors and the power windows.

Better still, I shall investigate using as much of the components to provide power doors for all doors including the bonnet/frunk, wheel and ventilation covers.
