Wiring Member Structure for Dissimilar Cover Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness technologies face challenges in attaching a cover made of a material different from the electrical wire's insulating covering to a sheet material, where the covering is directly fixed.
Innovation Solution
A wiring member design that includes a wire-like transmission member with a covering, a sheet material with a first fixing part for direct attachment to the covering, and a second fixing part specifically suited for attaching a cover made of a different material from the opposite side, allowing for effective direct fixation of the cover to the sheet material using an anchor effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover made of a material different from the electrical wire's insulating covering is attached to a sheet material where the covering is directly fixed, then the structural integrity and material compatibility are improved, but the complexity of the fixation structure increases
Solution Approach 1:
The sheet material is divided into two distinct fixing parts: a first fixing part for directly fixing the electrical wire covering, and a second fixing part for directly fixing the cover. This segmentation allows each fixing part to be optimized for its specific function and material compatibility, resolving the contradiction between structural integrity and fixation complexity.
Solution Approach 2:
Different regions of the sheet material are assigned different fixing properties: the first fixing part has properties suitable for bonding to the electrical wire covering material, while the second fixing part has properties optimized for bonding to the cover material. This local differentiation enables reliable fixation of dissimilar materials without requiring a complex overall structure.
2Ease of manufacture
If a second fixing part optimized for cover fixation is added to the sheet material, then the ease of attaching the cover is improved, but the manufacturing complexity of the sheet material increases
Solution Approach 1:
The sheet material is segmented into two fixing parts with distinct functions. The second fixing part is specifically designed and optimized for cover fixation, making cover attachment straightforward and easy to manufacture. This segmentation allows the sheet material to be manufactured with predetermined fixing zones, simplifying the overall attachment process despite the increased structural differentiation.
3Ease of operation
If direct fixation methods are used for both the covering and the cover, then the assembly process is simplified, but the adaptability to different materials is reduced
Solution Approach 1:
The sheet material incorporates a first fixing part with properties optimized for direct fixation to the electrical wire covering material, and a second fixing part with properties optimized for direct fixation to the cover material. This local quality differentiation enables direct fixation methods to be used for both components while maintaining high adaptability to different materials, as each fixing part is tailored to its specific material interface.
Solution Approach 2:
The sheet material serves multiple fixing functions through its two distinct fixing parts: it can directly fix both the electrical wire covering and the cover using appropriate fixation methods for each material type. This multi-functionality allows the single sheet material to adapt to different materials while maintaining assembly simplicity.

AI summary
A wiring member includes: a wire-like transmission member including a transmission wire body and a covering for covering the transmission wire body; a sheet material to which the wire-like transmission member is fixed; and a cover formed of a material different from a material of the covering, covering the wire-like transmission member from a side opposite to the sheet material, and fixed to the sheet material, wherein the sheet material includes a first fixing part to which the covering is directly fixed and a second fixing part which is directly fixed to the cover more easily than the first fixing part and to which the cover is directly fixed.
