Sheeted Harness Single-Side Wire Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheeted harnesses are costly and overly rigid, making them difficult to conform to curved surfaces and fold for packaging due to the use of two sheets and bundled electric wires.
Innovation Solution
A sheeted harness design featuring a single flexible and foldable sheet member with electric wires attached on one side, avoiding bundling and central branching to reduce rigidity and cost, allowing for easier installation and packing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two sheets are used to hold the harness, then the harness is protected and held securely, but the cost increases and the rigidity becomes excessive
Solution Approach 1:
The patent removes one sheet from the traditional two-sheet configuration, extracting only the essential protective function while eliminating redundant material. The single sheet is positioned to cover only the necessary areas, reducing cost and rigidity while maintaining adequate harness protection.
Solution Approach 2:
The sheet is configured to cover specific segments of the harness rather than providing complete encapsulation. The sheet member is positioned to protect the harness bundle in critical areas while leaving other areas exposed, achieving selective protection that reduces overall rigidity and material cost.
2Stability of the object's composition
If the harness is bundled and taped between sheets, then the harness is held securely, but the rigidity increases making it difficult to conform to curved surfaces
Solution Approach 1:
The patent employs a thin, flexible sheet member that can easily conform to curved surfaces such as vehicle roofs. The sheet is designed with sufficient flexibility to bend and adapt to various surface geometries while still providing secure holding of the harness through strategic positioning and attachment methods.
3Volume of moving object
If the harness is bundled tightly, then the harness is compact for storage, but the rigidity increases making it difficult to fold and handle
Solution Approach 1:
The patent creates a dynamic balance between bundling tightness and flexibility. The harness is secured with sufficient tension to maintain compact form factor for storage, but the single-sheet configuration allows the bundle to flex and fold when needed, enabling easy handling and installation without excessive rigidity.
4Reliability
If multiple sheets are used, then the harness is well-protected, but the cost increases
Solution Approach 1:
The patent extracts the essential protective function from the traditional two-sheet design and implements it with a single sheet. By carefully designing the sheet's position, size, and attachment method, adequate protection is achieved with reduced material quantity, lowering cost while maintaining reliability.

AI summary
A sheeted harness comprising a single piece of sheet member, and a plurality of electric wires arranged on the sheet member. The sheet member is provided on only one side of the plurality of electric wires. The plurality of electric wires is arranged on the sheet member such that a portion of each of the plurality of electric wires is attached, separately from one another without being bundled, to the sheet member.
