Our brief from client Carter Parratt was to carry out the industrial design engineering and product development for a new range of durable, lateral and suspension files that fitted into the company's various existing racking systems and office storage products, each wallet should be stylish, easy to use, tougher and longer lasting than other products on the market and have the facility to be locked together as a continuous concertina, but also be able to be easily separated for individual file removal.
To allow for the manufacture of a variety of colour variations (to denote particular subject fields), our patented design features injection moulded frames to which sheet polypropylene pockets are welded. The frames then accept a series of snap on index covers and joining clips.
We developed the features required on the frames using a variety of modelling and prototyping techniques, so that we could get as close as possible to the performance of the real finished product. Part of this process was to allow us to research the specification of the engineering plastic materials that would be used to achieve pocket and frame strength, stiffness and welding characteristics, to the required standard.
During the course of the new product design and development, we created all the engineering and production drawings for the UK manufacture of injection moulded components and also identified a Surrey based company capable of assembling and welding the wallets in mass production.
