Wire Harness Sheet Fusion Layout Around Branch Wires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wire harnesses, it is challenging to fuse an additional sheet to a functional exterior member without interfering with the wire-like transmission members, often resulting in incomplete or difficult fusion processes.
Innovation Solution
A wiring member design that includes a main wire with multiple wire-like transmission members, a branch wire, a fixing sheet, and a cover sheet, where the fusion position of the fixing sheet and the cover sheet is strategically located on the lateral side of the main wire, away from the branch wire, allowing for easier fusion without catching the wire-like transmission members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cover sheet is fused to the fixing sheet at a position overlapping the wire-like transmission members, then the fusion process is simplified, but the wire-like transmission members are caught by the fusion jig and fusion is hardly performed
Solution Approach 1:
The patent divides the fusion process into two distinct stages: first fixing the wire-like transmission members to the fixing sheet, then fusing the cover sheet at a position away from the wires. This segmentation allows each operation to be performed optimally without interference, resolving the contradiction between manufacturing simplicity and fusion reliability.
Solution Approach 2:
The wire-like transmission members are fixed to the fixing sheet before the cover sheet fusion process. This preliminary action ensures that the wires are securely in place and do not interfere with the subsequent fusion operation, enabling complete and reliable fusion of the cover sheet.
2Ease of manufacture
If the fusion position is located away from the branch wire, then the fusion process can be performed smoothly without catching the wires, but the structural integration is reduced
Solution Approach 1:
The patent applies different quality requirements to different regions: the fusion position is located away from the branch wire to ensure smooth fusion process, while the cover sheet still overlaps with the branch wire in other areas to maintain structural integration and protection. This local differentiation resolves the contradiction between manufacturing ease and structural stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables favorable fusion of the additional sheet to the sheet with fixed wire-like transmission members, preventing interference and ensuring a smooth fusion process, thus enhancing the operational efficiency of the wire harness.
Implementation Method 1
a fusion position where the fixing sheet and the cover sheet are fused is provided on at least a lateral side of the main wire in a longitudinal direction

AI summary
A wiring member includes: a main wire including a plurality of wire-like transmission members; a branch wire in which some of the wire-like transmission members are branched from the main wire; a fixing sheet having one main surface to which the main wire is fixed; and a cover sheet, at least a part of which is provided in a position overlapped with the branch wire in another main surface of the fixing sheet, wherein a fusion position where the fixing sheet and the cover sheet are fused is provided on at least a lateral side of the main wire in a longitudinal direction, and is provided in a position away from the branch wire.
