Title: Innovations of Keiichiro Mizuno: Advancements in Elastic Wheel Design
Introduction
Keiichiro Mizuno, a prolific inventor based in Tokyo, Japan, has made significant contributions to the field of engineering with a remarkable portfolio of 20 patents. His innovations focus primarily on enhancing performance and comfort in mechanical designs, particularly in the automotive sector.
Latest Patents
Among his latest inventions is the innovative elastic wheel, designed to revolutionize riding comfort and performance. This elastic wheel features a disk that includes a base rim and a rim for supporting a tire, with an annular elastic rubber body positioned between them. A unique gap is formed that enables the elastic rubber body to possess a variable spring constant. This design allows for effective vibration absorption under light loads while maintaining structural integrity under heavier conditions. The result is superior vibration-proof and soundproof performance without compromising durability and safety. Notably, the design effectively suppresses high-frequency noise, specifically at 100 Hz or higher, contributing to an enhanced overall riding experience.
Another variation of the elastic wheel improves upon this design by incorporating guides and wall portions to house the rubber elastic bodies. This configuration allows for additional vibration absorption through shearing deformations, further enhancing comfort and performance against small input loads and addressing high-frequency sound suppression effectively.
