Wiring Member With Weight Reduction Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing techniques for forming flat wiring members using sheet materials result in increased weight, necessitating a method to reduce the weight of such wiring members while maintaining their flat configuration.
Innovation Solution
A wiring member is designed with a sheet material that incorporates weight reduction spaces, such as bottomed holes or through holes, and a wire-like transmission member fixed to the sheet material via contact area direct fixation, utilizing materials like polyvinyl chloride, to minimize weight while maintaining structural integrity and protection capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a sheet material is used to keep the wiring member flat, then the wiring member maintains a flat configuration, but the weight of the wiring member increases
Solution Approach 1:
The sheet material incorporates weight reduction spaces (through holes or bottomed holes) to create a porous structure that reduces overall weight while maintaining the flat configuration. The holes are strategically positioned to remove unnecessary material without compromising the structural integrity needed to keep the wiring member flat.
Solution Approach 2:
The sheet material is segmented by dividing it into solid regions and hollow regions through the formation of weight reduction spaces. This segmentation allows the material to maintain its flat shape-providing function while reducing weight by removing material from specific areas where full density is not required.
2Weight of moving object
If weight reduction spaces are formed in the sheet material, then the weight is reduced, but the protection capacity may be reduced
Solution Approach 1:
The sheet material exhibits local quality variation through the strategic placement of weight reduction spaces. Areas with holes provide weight reduction, while solid areas maintain protection capacity. This local differentiation allows the material to optimize both weight and protective functions in different regions simultaneously.
Solution Approach 2:
The controlled porous structure formed by weight reduction spaces reduces weight while the remaining material framework maintains sufficient protection capacity. The porous design allows weight reduction without complete material removal, preserving the structural integrity needed for protection.
3Ease of manufacture
If contact area direct fixation is used to fix the wire-like transmission member, then the fixation is efficient, but energy concentration may cause material degradation
Solution Approach 1:
The contact area direct fixation applies fixing action only at specific contact points between the wire-like transmission member and the sheet material, rather than across the entire surface. This partial action achieves efficient fixation while avoiding excessive energy concentration that would degrade the material throughout the entire contact area.
Solution Approach 2:
The fixation process creates local quality changes at the contact areas where the wire-like transmission member bonds to the sheet material. This localized bonding provides efficient fixation strength at specific points without requiring excessive energy that would degrade the overall material integrity.

AI summary
A wiring member includes a sheet material in which a weight reduction space is formed and a wire-like transmission member fixed on the sheet material. For example, the weight reduction space includes a bottomed hole. For example, the sheet material includes a first base material in which a base material side through hole passing through the first base material in a thickness direction is formed and a second base material overlapped with the first base material to cover the base material side through hole, and the base material side through hole which is partially covered by the second base material forms the bottomed hole.
