Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing in-wheel electric motor drive systems face challenges in assembly due to misalignment of conductive connecting pieces and require a large wiring cavity, leading to increased assembly costs and space wastage.
Innovation Solution
The proposed solution involves an electric connection structure with a housing featuring a wiring cavity and channels for busbars and power supply connectors, along with a wiring support and connection assemblies that simplify assembly by eliminating separate conductive connecting pieces, reducing the wiring cavity volume, and using sealing rings for hermetic separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate conductive connecting pieces are used to connect electric motor busbars and power supply connectors, then electrical connection can be achieved, but assembly misalignment occurs and assembly difficulty increases
Solution Approach 1:
The patent integrates the conductive connecting piece directly into the power supply connector housing, forming an integrated connection assembly. This merging eliminates the separate conductive connecting piece, ensuring precise alignment between busbars and power supply connectors while maintaining reliable electrical connection, thereby resolving the assembly misalignment issue
2Ease of operation
If a large wiring cavity is provided to accommodate assembly tools, then assembly operation space is sufficient, but the overall device volume increases
Solution Approach 1:
The integrated connection assembly allows busbars and power supply connectors to be assembled directly within a compact wiring cavity, eliminating the need for a large operation space. The merged design enables tools to access the connection point more efficiently, reducing the required wiring cavity volume while maintaining assembly feasibility
3Reliability
If separate conductive connecting pieces and multiple fixing pieces are used, then electrical connection can be established, but device complexity and assembly cost increase
Solution Approach 1:
The patent combines the conductive connecting piece with the power supply connector into a single integrated assembly, reducing the number of separate components. This merging maintains reliable electrical connection while simplifying the overall structure, reducing device complexity and assembly cost
