Vehicle Compressor Stator Connector Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor-driven compressors for vehicles face challenges with the unfixed connector, which requires manual alignment and is prone to unstable positioning due to external impacts, limiting the axial length and efficiency of the compressor assembly.
Innovation Solution
The compressor design includes a connector with fixed slots on the stator and a connector body that securely attaches to the stator, allowing for stable positioning and reduced axial length by integrating the connector directly into the stator, enabling improved assembly and reduced space requirements between the electric motor and inverter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is provided at an end of the harness, then the terminals can receive power from the inverter, but the connector remains unfixed and requires manual alignment during assembly
Solution Approach 1:
The connector body is merged with the stator by directly fixing the connector to the stator, eliminating the need for separate harness routing and manual alignment. This integration ensures the connector is automatically positioned correctly during motor assembly, improving both ease of assembly and positioning stability.
2Device complexity
If the connector remains unfixed after assembly, then the structure is simpler, but the connector position may be unstably changed by external impacts
Solution Approach 1:
The connector body is preliminarily fixed to the stator before motor assembly, so that the connector position is predetermined and stable. This preliminary fixation prevents position changes due to external impacts while maintaining a relatively simple overall structure.
3Ease of operation
If space is allocated for harness connection between the electric motor and inverter, then the connector can be connected, but the axial length of the compressor increases
Solution Approach 1:
The connector body is merged with the stator, eliminating the need for separate harness routing space between the motor and inverter. This integration significantly reduces the axial length of the compressor while maintaining full connector connection capability.
