Soundproof cover of a compressor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soundproof covers for compressors suffer from noise leakage due to friction and vibration, leading to deteriorated sound absorption performance and structural noise generation, and are difficult to assemble effectively.
Innovation Solution
A soundproof cover comprising multiple detachable elements connected by magnetism, forming an air layer and using materials with different sound-blocking properties to minimize noise leakage and absorb vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sound absorbing member is attached to the compressor, then noise generated in the compressor is absorbed, but vibration causes friction against the sound absorbing member which generates friction noise and heats the member deteriorating sound absorbing performance
Solution Approach 1:
The patent introduces a soundproof cover as an intermediary component that surrounds the compressor. This cover includes a sound absorbing member positioned at a distance from the compressor outer surface, preventing direct contact between the vibrating compressor and the sound absorbing material. The cover body acts as a mediator that transmits sound while isolating the sound absorbing member from vibration-induced friction.
2Strength
If the cover is integrally formed to surround the compressor, then the compressor is protected, but vibration generated during operation may not be effectively canceled and structural noise is generated
Solution Approach 1:
The soundproof cover is divided into multiple detachable elements rather than being formed as a single integral structure. These elements are coupled to each other using magnetic coupling, creating a segmented assembly that can better accommodate and dampen vibrations. The modular structure allows for more effective vibration cancellation while maintaining protective coverage.
3Ease of manufacture
If both ends of the noise-blocking cover are fixed by Velcro material, then the cover is assembled, but a gap between the ends is gradually widened by vibration causing noise to leak
Solution Approach 1:
The patent replaces the mechanical Velcro fastening system with magnetic coupling between detachable elements. The magnetic attraction force maintains a secure connection between the cover ends without requiring physical contact or adhesive materials. This substitution eliminates the gap-widening problem caused by vibration while preserving ease of assembly and disassembly.

AI summary
Disclosed is a soundproof cover, more particularly, a soundproof cover of a compressor that includes two or more covers arranged to be detachably attached to each other to define a space for accommodating the compressor and is capable of preventing noise generated in the compressor from being transmitted to the outside. The soundproof includes a first cover spaced apart from an outer surface of the compressor to accommodate the compressor, and a second cover arranged so as to be detachably attached to the first cover and spaced apart from the outer surface of the compressor to accommodate the compressor. According to embodiments of the present invention, radiated noise and structural noise generated in the compressor may be effectively blocked. In addition, the assembly operation is facilitated, and accordingly mass productivity and assemblability may be improved.
