Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harnesses face challenges in efficiently mounting conductors, limiting members, and outer members onto holding members, leading to increased worker workload and reduced assembly efficiency.
Innovation Solution
A wire harness design featuring a flexible conductor, a flexible limiting member, and a holding member with distinct trenches and locking walls that facilitate easier mounting by separating the conductor and limiting member paths and allowing for independent insertion and locking of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a wire harness includes a conductor, a limiting member, and an outer member that are mounted together on a holding member, then the structure is more compact and integrated, but the mounting process becomes more complex and time-consuming
Solution Approach 1:
The holding member is divided into multiple independent trenches: a first trench for routing the conductor and a second trench for holding the limiting member. The partition wall separates these trenches, allowing each component to be mounted independently in sequence rather than as a single complex assembly, thus improving mounting efficiency while maintaining integrated structure
Solution Approach 2:
The partition wall is pre-formed as part of the holding member structure, creating predetermined separate spaces for different components. This preliminary segmentation allows workers to mount the conductor and limiting member in a straightforward sequential process without needing to complex positioning or alignment steps during assembly
2Productivity
If the holding member has separate trenches for conductor and limiting member, then the mounting process becomes simpler and faster, but the holding member structure becomes more complex
Solution Approach 1:
The partition wall, locking walls, and side walls are integrated into a single holding member component. The partition wall not only separates the trenches but also works together with the locking walls to secure the outer member, combining multiple functions into one structure that simplifies the overall assembly process while providing the needed complexity for secure mounting
3Reliability
If the locking walls project higher than the side walls and partition wall, then the outer member is securely locked in place, but the holding member height increases
Solution Approach 1:
The locking walls are designed to project to a higher position than the side walls and partition wall only at the specific locations where locking is needed. This localized height increase provides secure locking of the outer member without unnecessarily increasing the overall height of the holding member across its entire structure, maintaining compact dimensions while ensuring reliable locking

AI summary
A wire harness (WH) includes a flexible conductor (1) connecting a vehicle body (101) with a movable body (103) mounted on a vehicle (100) and sliding relative to the vehicle body (101), a flexible limiting member (2) extending along the conductor (1) to limit the path of the conductor (1), a flexible outer member (3) in which the conductor (1) and the limiting member (2) are inserted, and a holding member (5) having a first trench (51) for routing the conductor (1) and a second trench (52) adjacent to the first trench (51) and holding an end of the limiting member (2). The holding member (5) has a partition wall (53) separating the first trench (51) from the second trench (52), locking walls (54) facing each other and locking an end of the outer member (3), and side walls (55) defining the first trench (51). The locking walls (54) project higher than the side walls (55), and the partition wall (53) projects higher than the locking walls (54) in a height direction (H) of the side walls (54).
