Compound Wire Harness Shield Structure for Separate Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved transport efficiency of wire harnesses in vehicles, particularly for hybrid vehicles and electric automobiles, where existing wire harnesses are often transported in an integrated state, limiting efficiency.
Innovation Solution
A compound wire harness is introduced, comprising a first wire harness and a second wire harness that can be electrically connected. The first wire harness includes a core wire, insulating coating, terminal, connector housing, exterior ring, and a shielding member, while the second wire harness includes similar components with a focus on higher flexibility. The shielding member and shield shell are inseparably integrated, allowing for separate handling and transportation of the wire harnesses before integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wire harnesses are transported in an integrated state, then structural integrity is maintained, but transport efficiency deteriorates
Solution Approach 1:
The wire harness system is divided into a first wire harness and a second wire harness that can be transported separately. The first wire harness includes a first exterior ring with a shielding member, while the second wire harness includes a second exterior ring with a shield shell. These segmented components can be transported independently to improve logistics efficiency, then assembled together during installation to form the complete integrated structure.
2Reliability
If shielding member and shield shell are inseparably integrated, then electromagnetic shielding reliability is improved, but device complexity increases
Solution Approach 1:
The shielding member of the first wire harness and the shield shell of the second wire harness are designed to be inseparably integrated through engagement structures. The shielding member includes an engagement portion that fits into a corresponding recess in the shield shell, creating a unified electromagnetic shielding barrier. This merging ensures reliable electromagnetic shielding while the engagement structures maintain reasonable assembly simplicity.
