Title: Riki Otsuka: Innovator in Tank Manufacturing Technology

Introduction

Riki Otsuka is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of tank manufacturing, particularly through his innovative designs and methods. With a total of 2 patents, Otsuka's work focuses on enhancing the structural integrity and fatigue strength of tanks.

Latest Patents

Otsuka's latest patents include a tank and a manufacturing method thereof. The first patent describes a tank that achieves both burst strength and fatigue strength through a unique structure. This tank comprises a liner and a fiber-reinforced plastic (FRP) layer, which includes a hoop layer and a helical layer formed by winding fibers around the outer periphery of the liner. The innermost helical layer is designed as a smooth helical layer to prevent unevenness from transferring to the adjacent hoop layer. This innovation enhances the fatigue strength of the fibers themselves.

The second patent further elaborates on the tank's design, emphasizing the importance of the fiber bundles used in the helical layer. By reducing the sectional area of the innermost helical bundle, Otsuka effectively decreases the stepped portions that can negatively impact the outer hoop layer. This design improvement leads to increased fatigue strength in the adjacent outer layer, showcasing Otsuka's commitment to advancing tank technology.
