Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic shielding methods for electric and hybrid vehicles require cumbersome processes such as inserting wires into braided shields and lack sufficient workspace, making them inefficient and difficult to implement, especially in densely equipped areas.
Innovation Solution
A shield cover formed from a conductive metal plate processed into a U-shape with side, front, and back portions, allowing for sliding coverage of wiring harnesses without the need for braided wires, and optionally featuring a second shield cover for enhanced shielding and improved workspace management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional braided wire shielding is used, then electromagnetic shielding is achieved, but the process becomes cumbersome requiring wire insertion, terminal processing, and crimping
Solution Approach 1:
The patent extracts the wires from the braided shield structure, reversing the conventional approach. Instead of inserting wires into a pre-formed braid, the invention uses a flat shield cover that wraps around and covers the wires externally, eliminating the need for wire insertion and terminal crimping processes
Solution Approach 2:
The patent replaces the mechanical crimping and terminal connection system with a simple wrapping and fixing mechanism. The shield cover is wrapped around the wires and secured with tape or adhesive, substituting complex mechanical fastening with a simpler attachment method
2Area of stationary object
If conventional shielding methods are used, then electromagnetic shielding is provided, but sufficient work space cannot be maintained in front of electric wires
Solution Approach 1:
The patent transitions from a three-dimensional braided shield that requires radial space to a two-dimensional flat shield cover that wraps around the wires. This dimensional change allows the shielding to be applied in limited spaces where conventional braided shields would not fit, as the flat cover can conform to tight configurations
3Productivity
If braided wire shielding is used, then electromagnetic shielding is achieved, but terminal portion processing and crimping work are required
Solution Approach 1:
The patent extracts the wires from the braided shield structure, reversing the conventional approach. Instead of inserting wires into a pre-formed braid, the invention uses a flat shield cover that wraps around and covers the wires externally, eliminating the need for wire insertion and terminal crimping processes
Solution Approach 2:
The shield cover is designed to be self-applying through wrapping, eliminating the need for specialized terminal processing equipment and operations. The simple wrap-and-fix method allows workers to apply the shielding without requiring skilled terminal processing operations
