Adjustable Wire Harness Path Restriction With Sliding Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harnesses require redesign of path restricting members when changes occur in the routing path specifications, making it difficult to accommodate changes efficiently.
Innovation Solution
A wire harness design featuring a first and second path restricting cover that slide along the wire harness main body, allowing for adjustable path restriction by adjusting the width of overlapping between the covers, enabling easy accommodation of changes in specifications without the need for extensive redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single path restricting member is used, then the structure is simple, but it cannot easily accommodate changes in routing path specifications
Solution Approach 1:
The path restricting member is divided into multiple segments (first path restricting cover and second path restricting cover) that can be independently adjusted. Each cover can be positioned at different locations along the wire harness main body, allowing the overall restricted path length to be modified by changing the number and position of active segments without redesigning the entire structure.
Solution Approach 2:
The path restricting member transitions from a fixed, static structure to a dynamic, adjustable structure. The covers can be selectively attached and detached at different positions, enabling the system to adapt to varying routing path specifications through reconfiguration rather than redesign.
2Manufacturing precision
If the path restricting member is redesigned for each specification change, then the path restriction is precise, but the manufacturing time and cost increase
Solution Approach 1:
Multiple path restricting covers are prepared in advance with standardized designs. These pre-fabricated covers can be selectively assembled to match different routing path requirements, eliminating the need to redesign and remanufacture the entire path restricting member for each specification change while maintaining precise path restriction through proper selection and positioning of the covers.
3Adaptability or versatility
If multiple path restricting covers are used, then the adaptability to specification changes improves, but the assembly complexity increases
Solution Approach 1:
The system uses segmented path restricting covers that can be independently selected and assembled. This segmentation allows for flexible configuration where only the necessary number of covers are assembled based on the specific routing path requirements, simplifying the assembly process compared to assembling a single complex custom-designed component.
Solution Approach 2:
The path restricting covers are designed with universal attachment features that allow them to be used in multiple positions and configurations. This multi-functionality enables the same cover design to serve different purposes in different arrangements, reducing assembly complexity while maintaining high adaptability to various specification requirements.
