Segmented Wire Route Restrictor for Variable-Diameter Harnesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route restricting members for electric wires require multiple components and are complex to manufacture, limiting their applicability to wires of specific diameters and increasing costs.
Innovation Solution
A route restricting member composed of a sheet-shaped first and second sheet member, each with alternating peak and valley portions, wound around the wire, with a fitting extension portion allowing the second member to attach to the first, reducing components and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a route restricting member is designed to cover more than half of the exterior member's outer periphery, then the electric wire routing path is restricted, but the member cannot be directly attached to the electric wire and requires additional exterior members
Solution Approach 1:
The route restricting member is divided into a first sheet member and a second sheet member that can be separately attached to the electric wire. The first sheet member is wrapped around the electric wire first, then the second sheet member is wrapped around and fitted to the first sheet member, creating a segmented attachment system that directly secures to the wire without requiring additional exterior members.
Solution Approach 2:
The second sheet member is designed to be fitted over the first sheet member, creating a nested structure where the second sheet member encompasses the first sheet member. This nested configuration allows both sheet members to work together as an integrated route restricting system while maintaining direct attachment to the electric wire.
2Reliability
If the route restricting member is attached using an exterior member like a corrugated tube, then the routing path is restricted, but the manufacturing process becomes more complicated and manufacturing cost increases
Solution Approach 1:
The first sheet member and second sheet member are combined into a single integrated route restricting member system. Both sheet members are designed to be directly attached to the electric wire without requiring separate exterior members, merging the attachment function into one unified structure that simplifies the manufacturing process and reduces assembly steps.
3Device complexity
If the route restricting member is designed for a preset electric wire diameter, then the structure is simplified, but it can be attached only to wires of that specific diameter
Solution Approach 1:
The sheet members are designed with flexible, deformable characteristics that allow them to adapt to different electric wire diameters. The sheet members can be elastically deformed during the wrapping and fitting process to accommodate various wire sizes, providing a dynamic adaptation capability that maintains structural simplicity while increasing versatility across different wire diameters.

AI summary
A route restricting member restricts a path along which an electric wire is routed. The route restricting member includes a sheet-shaped first sheet member including a first peak portion and a first valley portion that extend in an axial direction of the electric wire and are alternately connected on an outer surface in a direction intersecting the axial direction, and a sheet-shaped second sheet member including a second peak portion and a second valley portion that extend in the axial direction and are alternately connected on an outer surface in the intersecting direction. The second sheet member includes a fitting extension portion extending toward the first sheet member in the axial direction and fitted to the outer surface of the first sheet member.
