Soundproof cover of compressor for air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soundproofing materials for air conditioner compressors, such as those using aluminum plates, can generate solid-borne sound due to vibrations, necessitating additional cushioning materials for effective noise suppression.
Innovation Solution
A soundproof cover comprising a rubber or thermoplastic-elastomer molded product with sound-insulating properties, including a sound-insulating material body and head portion, and a sound-absorbing material inside the body portion, designed to fit the compressor's shape and reduce noise leakage through vibration isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If aluminum plate is used as soundproofing material, then soundproofing performance is improved, but solid-borne sound is generated due to vibration interference with peripheral parts
Solution Approach 1:
The patent replaces rigid aluminum plates with flexible rubber or thermoplastic elastomer materials that conform to the compressor shape. These flexible materials absorb vibrations through elastic deformation rather than transmitting them as solid-borne sound, while still providing effective soundproofing by blocking noise leakage paths.
Solution Approach 2:
The invention uses composite material structures combining rubber or thermoplastic elastomer with sound-absorbing materials (such as foam or fiber materials) to achieve both vibration isolation and sound absorption. This composite approach addresses both the soundproofing requirement and the solid-borne sound problem simultaneously.
2Object-affected harmful factors
If multiple cushioning materials are added to prevent solid-borne sound, then soundproofing performance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the functions of soundproofing and vibration isolation into a single integrated material system. The rubber or thermoplastic elastomer material serves both as the primary soundproofing layer and as the vibration-absorbing cushioning layer, eliminating the need for separate cushioning materials and simplifying the overall structure.
Solution Approach 2:
By creating a composite material structure where sound-absorbing materials are integrated within or attached to the rubber/thermoplastic elastomer base material, the invention achieves multiple functions (soundproofing, vibration isolation, and cushioning) in a unified component that is easier to manufacture and install than multiple separate layers.
3Object-affected harmful factors
If rigid soundproofing materials are used, then soundproofing performance is improved, but workability and installation ease deteriorate
Solution Approach 1:
The use of rubber or thermoplastic elastomer materials provides flexibility and elasticity that allow the soundproofing cover to be easily molded into complex shapes matching the compressor geometry. These materials can be stretched, bent, and adjusted during installation, significantly improving workability compared to rigid materials that require precise cutting and fitting.
