Latest Patents

Doi’s listed patents address practical challenges in wire-harness installation and vehicle assembly.

- **Wire protective member.** This invention covers a wire with a protective member made from a first base with an adhesive layer, a second base, and spacers between the bases. The adhesive layer bonds directly to the wire, helping avoid clearance between the wire and its protective covering. The design can save space and simplify installation by combining the protective components into one member, reducing both assembly effort and the number of parts.

- **Clamp for use in wire harness.** This clamp includes a plate with a harness-mounting part and two stems connected by a spanning part. Vane supports and vanes extend from the stems, with vehicle-body locking parts at the vane tips. When the harness is pulled in the withdrawal direction, the spanning part twists toward the cavity, helping release the locking parts from the vehicle-body opening.

Career Highlights

Doi’s listed inventions focus on components used in wire-harness systems. The protective member is designed to make wire covering more compact and straightforward to install, while the clamp provides a mechanism for fastening and releasing a harness at a vehicle body.
