Hinged Insulating Box Assembly for Compressor Electrical Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical arrangement assemblies for refrigeration compressors in the external region of hermetic housings are difficult to assemble, prone to misalignment, and lack effective protection against insects and moisture due to mechanical coupling methods and incomplete insulation.
Innovation Solution
An insulating box with a hinge element and pivot handle allows angular movement for precise electrical terminal connection, combined with sealing means like gaskets or contour ribs to prevent insect and moisture ingress, ensuring secure and efficient assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical coupling with translational movement is used to connect electrical terminals, then electrical connection is achieved, but misalignment between terminals occurs and assembly becomes difficult
Solution Approach 1:
The patent replaces the traditional mechanical translational coupling system with a rotational coupling mechanism. The insulating box rotates relative to the electrical interface, allowing electrical terminals to connect through rotational movement rather than translational movement. This substitution eliminates misalignment issues and simplifies assembly operations.
Solution Approach 2:
The patent changes the motion parameter from translational to rotational. By modifying the movement type from linear translation to rotation, the system achieves better alignment between electrical terminals and eliminates the difficulty of manual assembly while maintaining reliable electrical connection.
2Reliability
If insulating box is used to enclose electrical arrangement, then electrical isolation is provided, but insects and moisture can still enter through structural recesses
Solution Approach 1:
The patent introduces a sealing membrane or gasket that flexes to close structural recesses in the insulating box. This flexible sealing element prevents insects and moisture from entering through the recesses while maintaining the electrical isolation function of the insulating box.
Solution Approach 2:
The patent introduces a sealing membrane as an intermediary element between the insulating box interior and exterior environment. This membrane mediator blocks harmful factors like insects and moisture from entering through structural recesses while allowing the insulating box to maintain its electrical isolation function.
3Strength
If screws are used to secure insulating box to compressor housing, then mechanical fixation is achieved, but assembly becomes more difficult
Solution Approach 1:
The patent replaces the screw-based mechanical fixation system with a snap-fit or clip-based retention mechanism. The insulating box engages with the compressor housing through rotational movement and structural interlocking, eliminating the need for screws and simplifying assembly while maintaining strong mechanical fixation.
