Segmented Resin Tube Covering for Bent Flat Conductors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductive members with bent portions face challenges in inserting flat conductors into resin tubes, leading to wrinkles and instability in the insulation film due to line length differences, which affects manufacturing costs and coverage accuracy.
Innovation Solution
A conductive member design featuring a strip-shaped flat conductor with bent portions, covered by multiple resin tubes and adhesive tapes, where the resin tubes have oblique cut portions to avoid covering the bent portions, ensuring smooth installation and stable insulation film formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single resin tube is used to cover the flat conductor, then the structure is simple, but wrinkles occur due to bending causing unstable dimensions and poor coverage
Solution Approach 1:
The patent divides a single resin tube into multiple segments (first resin tube and second resin tube) that are installed separately on either side of the bent portion. This segmentation prevents wrinkles by avoiding the need for the resin tube to span the bent area, thereby maintaining stable dimensions and proper coverage without compromising the overall simplicity of the structure.
2Stability of the object's composition
If the resin tube covers the bent portion, then continuous coverage is achieved, but wrinkles occur due to line length difference
Solution Approach 1:
The patent extracts or removes the bent portion from the coverage area of the resin tubes. By intentionally leaving the bent portion uncovered and using adhesive tape instead, the resin tubes can maintain their original dimensions without wrinkles, while the bent portion still receives protection through the alternative adhesive tape solution.
3Stability of the object's composition
If adhesive tape is used to block gaps, then coverage continuity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent introduces adhesive tape as an intermediary element between the first and second resin tubes. This adhesive tape blocks gaps and ensures coverage continuity at the bent portion without requiring complex modifications to the resin tubes themselves, thereby achieving continuous coverage with minimal increase in manufacturing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents wrinkles in the resin tubes, maintaining a stable insulation film dimension and accurate coverage without obstructing coupling portions, thus reducing manufacturing costs and improving installation efficiency.
Implementation Method 1
an adhesive tape wound to block a gap between the first resin tube and the second resin tube where the bent portion is exposed
Implementation Method 2
a plurality of resin tubes installed to cover a periphery of the flat conductor excluding the bent portion

AI summary
A conductive member includes a strip-shaped flat conductor having a bent portion bent in a width direction, a plurality of resin tubes installed to cover a periphery of the flat conductor excluding the bent portion, in which the plurality of resin tubes include a first resin tube configured to cover a first portion of the flat conductor and second resin tube configured to cover a second portion of the flat conductor located adjacent to the first portion, with the bent portion disposed in between, and an adhesive tape wound to block a gap between the first resin tubes and the second resin tube where the bent portion is exposed
