Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configurations for electric wire protection members that combine electromagnetic wave absorption and protection against contact damage result in an increased number of components, which can lead to additional issues such as vibration-induced damage to the electric wires.
Innovation Solution
An electric wire protection member is designed with a case that houses a magnetic core and includes a covering portion to prevent contact with the exterior member's edge, where the case and core housing are formed in one piece, reducing the number of components and incorporating a locking mechanism for secure attachment to the exterior member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate case and magnetic core configuration is used for electromagnetic wave absorption, then electromagnetic wave absorption function is achieved, but the number of components increases
Solution Approach 1:
The patent combines the case structure and magnetic core into a single integrated component. The case includes a core housing portion that houses the magnetic core, and these are formed in one piece as a unified structure rather than separate components, thereby achieving electromagnetic wave absorption without increasing component count
Solution Approach 2:
The case is designed to serve multiple functions: it provides structural protection for the electric wire, houses the magnetic core for electromagnetic wave absorption, and includes a covering portion for edge protection. This multi-functional design eliminates the need for separate components for each function
2Object-affected harmful factors
If electromagnetic wave absorption member is attached to the lead-out section, then electromagnetic wave absorption is achieved, but the electric wire is likely to come into contact with the inner circumferential edge portion due to weight
Solution Approach 1:
The patent merges the electromagnetic wave absorption function with the wire protection function into a single integrated component. The case with covering portion and the magnetic core work together as one unit, eliminating the need for separate attachment that would cause weight-related contact issues
Solution Approach 2:
The covering portion of the case is designed to cover the inner circumferential edge at the end of the tube beforehand, preventing the electric wire from coming into contact with the edge portion. This protective covering is built into the structure before assembly, eliminating the need for additional protective components
