Latest Patents
Kanayama's latest patents include a "Rigidity Control System for Variable Rigidity Structure." This invention introduces a system that incorporates variable rigidity elements, such as braces, to adjust the rigidity of a structure dynamically. By varying the rigidity, the system aims to attenuate vibrations caused by external forces like earthquakes and wind. The control mechanism mimics the tension and relaxation of muscles in a living body, allowing for a self-balancing function. The invention outlines four vibrational conditions of a frame, enabling continuous responses to be detected by sensors. This ensures that the structure remains rigid during deformation increases and resilient during decreases, effectively avoiding resonance with seismic motions.
Another significant patent is the "Method of Controlling Building Against Earthquake." This method involves real-time analysis of earthquake data collected from sensors placed within the building and surrounding areas. By varying the connecting conditions based on earthquake response forecasts, the method adjusts the building's rigidity or applies counter forces to control oscillation according to the specific characteristics of each earthquake.
