Initial concepts explored a variety of materials and finishes, mechanisms and stack-up geometry. Ultimately the concepts that utilized thin sheet-metal over an injection molded body that could be UV printed upon, trumped the other material stack-up constructions. Read below to see how the design influenced the Mechanical engineering.

FlashCard engineering was highly dependent on balancing the intended look and feel of a thin, sleek product, with the manufacturing realities based on material limitations. To make sure we produced a design that was manufacturable we worked early on with the plastics vendor to establish minimum wall thicknesses that would allow us to push the design as thin as possible. Efficient back and forth provided a design that had the look and feel we required with full sign on of the manufacturer.

Efficient back and forth provided a design that had the look and feel we required with full sign on of the manufacturer. Another challenge in the flash card design is the attachment of sheet metal to plastic, while fairly common practice the flashcard is challenging as there is very limited contact area due to coring. As such we worked closely with adhesive vendors to determine a solution that would be both easy to apply while still providing sufficient strength.
