With a total of six patents to his name, Hanakawa's innovations focus on enhancing vehicle safety and structural integrity.

Latest Patents

One of Hanakawa's latest patents is a body frame structure for a vehicle and the method for manufacturing it. This invention involves forming a pair of left and right front frames with brittle sections on their proximal portions. These sections are designed with a smaller cross-sectional area than other parts of the frame. The brittle sections undergo a hardening treatment, such as quenching, to ensure they do not buckle during the early phase of a collision, thereby inducing a larger initial load. Eventually, the brittle sections will buckle due to their lower ductility, allowing the front frames to bend and effectively absorb collision energy.

Another significant patent is for a formed member made of steel sheet and the method for producing it. This method involves preparing a steel sheet material with a tensile strength of 500 MPa or less, which contains a nitriding element. The formed member is created through plastic forming, followed by a nitriding treatment to achieve a high hardness level while maintaining plastic formability. This innovation ensures that the formed member has sufficient strength after treatment.
