The situation

Lite Launcher’s product ranges included launchers that fire dummy objects for dogs and gundog scurries at numerous game and country fairs. The firing mechanism on the early models was released by a motor- driven catch moving along a groove. This proved to be somewhat unreliable and inefficient. 

The challenge

NSF Controls was approached to develop a more dependable, user friendly and cost effective method of operating the firing pin.

The solution

Using a solenoid as an alternative means of actuation involved several application-specific issues being identified and addressed. In particular, the solenoid had to be able to withstand the significant recoil forces without mechanical failure.

Development and tests were carried out using a size 3E rotary solenoid operating on a spring-loaded plunger. Additional features incorporated included a release lever and return spring support, which also provided a resilient mounting within the assembly    

The results and future

The challenge was met to improve the launcher's reliability whilst remaining within budgetary targets for a market viable product.

Lite Launcher products were exclusively marketed by a UK stockist, Sporting Saint Ltd, who later acquired the company. 

"I gave NSF clear goals for my project and they communicated well throughout the process. Technical support was excellent, with samples provided quickly. The design improvements enabled us to market the product to a much wider audience and build on its success."

- Mr Paul Davies, Managing Director, Lite Launcher
