Title: **Innovator Shuhei Tsunoda: A Leader in Engine Start Technology**

Introduction

Shuhei Tsunoda, a talented inventor based in Tokyo, Japan, has made significant contributions to the field of engine start technology. With a remarkable portfolio comprising 12 patents, Tsunoda is recognized for his innovative solutions that enhance the reliability and efficiency of small engine starters.

Latest Patents

Among Tsunoda's most notable inventions are his latest patents, which include the design of a starter for small engines. This innovative starter captures energy within a horsepower spring to ensure a reliable engine start. The design features a stopper that engages with the cam plate's depressed area and is strategically positioned near the cam plate, which is integrally formed with a pulley fixed to the engine crank shaft. This mechanism allows the stopper to transition between two positions: the engaging position, where it connects with the depressed area, and the avoidance position, which prevents interference with the rim of the cam plate. A unique urging mechanism supports the stopper's movement, ensuring optimal functionality while accounting for rotation load.

Another significant invention is Tsunoda's recoil starter. This system consists of a case housing a support shaft and a rotatable rope reel that is wound with a recoil rope. A recoil spring, in conjunction with a power-storing spring, enhances the starter's effectiveness by energizing the rope reel. The innovative ratchet mechanism includes a ratchet shaft on the rope reel, and a ratchet member that effectively engages with the cam's engaging portions. This intricate design showcases Tsunoda's ability to integrate complex mechanical systems into practical applications.
