One of the numerous products that Optima have designed for a major security client is a 2-Way activation key fob that is compatible with the class leading i-on and Menvier product ranges.
Optima developed the device from concept sketch level through a number of digital and physical prototypes to fully realised, tool ready, CAD data. The final product efficiently used space to house a complex component set within an attractive and robust clamshell assembly. One critical area of the design was the touch and feel of the plastic button deformation, providing a positive contact and feedback from the four internal tactile switches. In order to achieve the desired effect we undertook analysis to assist with material selection and wall thickness, utilising the inherent properties of the material to reduce component count.
The PD6662:2010 compliant keyfob was designed to optimise radio range and extend battery life via an easily replaceable button cell, ensuring the device surpassed performance expectations of a radio control device of this type. It was also formulated for robustness, usability and ease of assembly whilst been aesthetically appropriate for use with the clients, high specification, domestic and commercial security systems.
