Uniform Protective Member for Electric Wire Noise Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective member-attached wires have regions with impaired noise insulation and protection abilities due to the uneven distribution of harder and softer portions around electric wires, leading to inconsistent performance.
Innovation Solution
A protective member-attached wire design featuring a sheet-shaped nonwoven member with a first portion obtained by heating and a softer second portion, both distributed uniformly around the electric wire, ensuring consistent protection and noise insulation by being wrapped multiple times and separated in the width direction, with the first portion recessed and the second portion softer, facilitating easy manufacturing and adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective member has regions with only the first portion or only the second portion, then the protection ability or noise insulation ability is improved in that region, but the overall uniformity of protection and noise insulation abilities is worsened
Solution Approach 1:
The protective member incorporates both a first portion (obtained by heating) and a second portion (softer) within the same structure. The first portion provides enhanced protection ability while the second portion provides enhanced noise insulation ability. Both portions are distributed over the entire circumference and length of the protective member, ensuring uniform performance throughout.
2Ease of manufacture
If the first portion and second portion are concentrated in specific regions, then the manufacturing process is simplified, but the noise insulation and protection abilities become inconsistent around the electric wire
Solution Approach 1:
The protective member incorporates both a first portion (obtained by heating) and a second portion (softer) within the same structure. The first portion provides enhanced protection ability while the second portion provides enhanced noise insulation ability. Both portions are distributed over the entire circumference and length of the protective member, ensuring uniform performance throughout.
3Device complexity
If the protective member uses a single uniform material, then the manufacturing process is simplified, but the ability to provide both protection and noise insulation uniformly is reduced
Solution Approach 1:
The protective member is constructed as a composite structure with two distinct portions: a first portion obtained by heating the nonwoven member and a second portion that is softer. This composite structure allows the first portion to provide protection ability while the second portion provides noise insulation ability, achieving both functions uniformly around the electric wire.

AI summary
A protective member-attached wire is provided with: an electric wire; and a protective member that is made of a sheet-shaped nonwoven member and is wrapped around the electric wire to cover the electric wire. The protective member includes: a first portion obtained by heating a portion of the nonwoven member; and a second portion that is softer than the first portion of the nonwoven member. The first portion and the second portion are each distributed over the entire circumference of the electric wire in a circumferential direction of the electric wire, and are distributed over the entire protective member in a longitudinal direction of the electric wire.
