Wiring Member With Variable Fixation Intervals For Strength Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring member technologies lack a specific range for welding between a band-like body and a covering wire, resulting in inconsistent fixing strength across different portions.
Innovation Solution
A wiring member with a sheet material and a wire-like transmission member fixed by contact area direct fixation at varying intervals, allowing for differential fixation intervals to achieve appropriate strength in each portion, with increased intervals in areas where high strength is not necessary and reduced intervals where high strength is required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a uniform fixation interval is used across the entire wire-like transmission member, then the manufacturing process is simple, but the fixing strength becomes inconsistent and insufficient in portions requiring high strength
Solution Approach 1:
The patent applies local quality by setting different fixation intervals for different portions of the wire-like transmission member. Specifically, a first fixation interval is used for a first portion and a second fixation interval (shorter than the first) is used for a second portion, allowing high fixing strength where needed while maintaining simplicity elsewhere. This resolves the contradiction by making the fixation structure adaptive to local requirements rather than uniformly complex.
Solution Approach 2:
The wire-like transmission member is segmented into multiple portions with different fixation characteristics. The member is divided into a first portion and a second portion, each with dedicated fixation intervals. This segmentation allows the system to achieve varying fixing strengths across different sections, resolving the contradiction between uniform simplicity and localized strength requirements.
2Strength
If the fixation interval is reduced in all portions to ensure high fixing strength, then the fixing strength is improved, but the manufacturing time and material consumption increase
Solution Approach 1:
Instead of reducing the fixation interval uniformly across the entire member, the patent applies the shorter second fixation interval only to the second portion where high fixing strength is required. The first portion maintains the longer first fixation interval, thereby achieving necessary strength localization while minimizing manufacturing time and material consumption. This resolves the contradiction by avoiding unnecessary fixation in portions where high strength is not required.
3Strength
If a shorter fixation interval is used in portions requiring high strength, then the fixing strength is improved, but the overall manufacturing complexity increases
Solution Approach 1:
The patent implements local quality by configuring different fixation intervals for different portions based on their specific strength requirements. The second portion with higher strength demands uses the shorter second fixation interval, while the first portion uses the longer first fixation interval. This localized approach achieves the necessary strength improvement without requiring complex variable pitch mechanisms across the entire manufacturing process.
Solution Approach 2:
The manufacturing approach is segmented into distinct fixation zones corresponding to different portions of the wire-like transmission member. Each segment has its own optimized fixation interval, allowing simple manufacturing processes to be applied separately to each segment rather than requiring a single complex variable process for the entire member.

AI summary
A wiring member includes a sheet material and a wire-like transmission member extending in a plane direction of the sheet material and fixed to the sheet material by a contact area direct fixation at intervals in three or more positions in a longitudinal direction of the wire-like transmission member. When an interval between two contact area direct fixation positions continuous in a longitudinal direction of the wire-like transmission member in contact area direct fixation positions of the sheet material and the wire-like transmission member is a fixation interval, the wiring member includes portions that differ in the fixation interval.
