Engineering

Parallel path design of electronic, mechanical and packaging components led to the rapid development of the first functional models for limited preview at the Consumer Electronics Show in February. Based on our collective efforts, 10 working units were fabricated and delivered in time for the show. The resulting early prototypes gave KidSmart precisely what they needed for marketing purposes and also enabled early safety / compliance testing of the design including testing at UL in their “smoke box.” Bill of materials and CAD files were distributed to qualified production vendors for competitive quoting. All the while, the development team kept pressing forward with the production design. Critical electronics tasks included final testing and selection of key smoke sensing components as well as the maturation of firmware and software. Mechanical engineering focused on problem solving around key interface elements including resolution of battery chamber, test buttons and indicators, as well as fine tuning the internal features for maximum air flow to the smoke sensor, and output of high quality voice recording. Usability sequences, product color and graphics were finalized.
