Company information
A Challenge to Transform "Impossible" into "Possible" in Design Quality One day, we received a development project for a new wearable device that pursued unprecedented thinness and lightness. The client's request was, "It must be completely waterproof while not compromising on design at all." The project initially ran aground due to this conflicting challenge. The thickness of the casing was just a few millimeters. With conventional waterproofing technology, it was not only difficult to protect the internal precision instruments but also to maintain design integrity. While many engineers threw in the towel, declaring it "impossible," the challenge at Kamigami Corporation began. Our team first thoroughly utilized 3D data as part of our DX promotion, repeatedly conducting simulations in a virtual space. This was a crucial process to eliminate rework and improve development productivity. Drawing on the experience and insights that our representative, Suzuki, had cultivated over many years in developing some of the world's thinnest waterproof designs for smartphones, we meticulously analyzed every possible water intrusion route, leaving no 0.1 millimeter gap unchecked. We pursued the highest design quality and devised a new waterproof structure that overturned conventional wisdom.
