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

VSEngineering 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

Engineering Contradiction:
Improvewaterproof protectionVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple assembly steps are used for mounting the temperature sensor, then the sealing reliability is improved, but the assembly time increases

Engineering Contradiction:
Improvesealing reliabilityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveassembly simplicityVSAvoiddust and liquid ingress
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #5Merging (Combining)
