Integrated terminal for compressor, compressor assembly, and heating and ventilation apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of a temperature sensor on a compressor is cumbersome, requiring multiple steps and involving a complex assembly of a water-proof gasket, temperature sensor terminal, and terminal cover with a bolt.
Innovation Solution
An integrated terminal for a compressor that integrates a temperature-sensing component and a connection wire harness, featuring a dust-proof housing, temperature-sensing component, and connection wire harness, which are assembled by connecting the integrated terminal to the compressor in a locked manner, forming a sealing structure to prevent liquid and dust ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the temperature sensor is assembled using multiple separate components (water-proof gasket, terminal cover, bolt), then the waterproof protection is improved, but the assembly complexity increases
Solution Approach 1:
The patent integrates the temperature sensor, wire harness, and sealing structure into a single integrated terminal assembly. This merging of previously separate components (temperature sensor, water-proof gasket, terminal cover, and wiring) into one pre-assembled unit directly reduces assembly complexity while maintaining the waterproof protection function through the integrated sealing design.
2Reliability
If multiple assembly steps are used for mounting the temperature sensor, then the sealing reliability is improved, but the assembly time increases
Solution Approach 1:
The integrated terminal assembly is pre-assembled with the sealing structure and temperature sensor configured together before installation. This preliminary action of pre-configuring the sealed assembly eliminates the need for multiple sequential assembly steps during final installation, reducing assembly time while maintaining sealing reliability through the pre-verified integrated design.
3Ease of operation
If the connection wire harness is exposed without sealing, then the assembly simplicity is improved, but the dust and liquid ingress risk increases
Solution Approach 1:
The wire harness is integrated with the sealing structure as a unified component rather than a separate exposed element. This merging ensures that the wire harness is automatically protected by the sealing structure, preventing dust and liquid ingress while maintaining assembly simplicity through the integrated design that requires no additional sealing steps.
