Vehicle Contactor Orthogonal Layout for Compact Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contactors have a long structure, large space occupation, low structural strength, and a high risk of fracture due to vibration, limiting their use as automotive-grade components with a short service life.
Innovation Solution
A contactor design with a conducting bar that is revolvable and arranged orthogonally to wiring terminals, combined with a compact driving assembly, reduces overall length and enhances structural stability, incorporating flexible materials to minimize wear and noise, and integrates arc-extinguishing mechanisms for improved durability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the moving contact, conducting bar, and driving assembly are arranged sequentially in the length direction, then the contactor can be manufactured with simple structure, but the overall length becomes large and space occupation increases
Solution Approach 1:
The patent transforms the traditional linear sequential arrangement (length direction) into a multi-dimensional layout where the first and second wiring terminals are arranged in a first direction and the conducting bar is arranged in a second direction perpendicular to the first direction. This dimensional change reduces the overall length while maintaining manufacturing simplicity.
2Ease of manufacture
If the moving contact, conducting bar, and driving assembly are arranged sequentially in the length direction, then the structure can be simple to manufacture, but the structural strength becomes low and fracture risk increases
Solution Approach 1:
By arranging components in perpendicular directions rather than sequential length direction, the patent creates a more compact three-dimensional structure that distributes stress more effectively, thereby improving structural strength and reducing fracture risk while maintaining manufacturing simplicity.
3Stability of the object's composition
If the conducting bar is fixed rigidly to reduce wear, then structural stability improves, but noise increases due to impact during connection and disconnection
Solution Approach 1:
The patent applies a flexible connection between the conducting bar and wiring terminals, allowing the conducting bar to have slight flexibility. This flexibility cushions the impact during connection and disconnection, reducing noise while maintaining sufficient structural stability for normal operation.
