Weijia is specialised in work lights, which is a very competitive market. The challenge for Weijia is to develop its own products, offering specific values of use and character. Our collaboration is based on creativity upstream, without a restrictive briefing. From the creative step, the concepts are analysed and developed. We participate fully in the technical development always linked in parallel to the control of the shape evolution. The game is to always maintain the balance between the original concept, the technical constraints, the cost and the final image. As an example, this new led torch.
