Title: Kiyoshi Negishi: Innovator in Clothing Simulation and Shock-Absorbing Structures.
Introduction
Kiyoshi Negishi is a notable inventor based in Ohtsu, Japan. He has made significant contributions to the fields of clothing simulation and structural engineering. With a total of 3 patents, his work showcases innovative solutions that address practical challenges in design and construction.
Latest Patents
Negishi's latest patents include a clothing simulation apparatus, a clothing simulation program, and a clothing simulation method. The clothing simulation apparatus is designed to precisely determine clothing pressure for bringing clothing into tight contact with the human body. This apparatus features a fitting part that divides a paper pattern model into multiple elements, imparting dynamic characteristics shown by a fabric model to each element. It deforms the paper pattern model by solving the motion equation of each element using a finite element method, allowing for virtual fitting of clothing to a human body model. Additionally, the fitting part sets a temporary model to cover a predetermined section of the human body model, ensuring accurate contact between the paper pattern model and the human body.
Another significant invention is the bridge of shock-absorbing construction. This bridge includes horizontal members arranged in series, vertical members supporting the horizontal members, and connectors for connecting adjacent horizontal members or for connecting horizontal and vertical members. Shock absorbers made from a material with an elastic modulus in flexure over 200 kgf/cm are strategically placed on the connectors or at points of contact between the horizontal members.
