Title: Hideki Toyoyama: Vehicle Lighting and Exterior Component Innovations.

Introduction

Hideki Toyoyama is an inventor based in Kiyosu, Japan, whose patent work focuses on vehicle exterior and light-emitting components. He is associated with Toyoda Gosei and is credited with 2 patents.

Latest Patents

Toyoyama’s latest patents address practical design considerations in vehicle components.

“Vehicle Exterior Component” describes a housing with an outer lens and an internal light-emitting substrate. A vent hole in the housing’s bottom is surrounded by a protruding boss, which is closed by a lid that allows gas to pass while restricting liquid. This arrangement supports ventilation while helping limit liquid entry.

“Vehicle Light-Emitting Component” concerns an outer lens made from two integrally formed molded parts with different light-transmitting properties. The patent specifies how the thickness of the second part near its boundary with the first part is reduced, including a radial end thickness of no more than 0.8 mm in one configuration.

Career Highlights

Toyoyama’s listed patent portfolio centers on vehicle lighting and exterior-component design. His work addresses both environmental protection around a light-emitting assembly and the construction of lenses with differing optical properties.

Collaborations

Toyoyama is associated with Toyoda Gosei. Yuto Arai is identified as a coworker.

Conclusion

Hideki Toyoyama’s patents reflect a focus on functional vehicle components, combining ventilation and liquid restriction with carefully designed light-transmitting lens structures.
