Engineering Contradiction Analysis
1Speed
If high-velocity gas streams are used in air amplifiers, then the air amplification effect is improved, but unwanted noise is generated
Solution Approach 1:
The patent utilizes the high-velocity gas stream that generates noise as a tool to drive noise suppression mechanisms. The same high-velocity stream that causes noise is channeled through acoustic absorption materials and noise suppression chambers, converting the harmful noise-generating flow into a beneficial force that drives the noise cancellation process while maintaining air amplification effectiveness
2Object-generated harmful factors
If noise suppression mechanisms are added to air amplifiers, then unwanted noise is reduced, but device complexity increases
Solution Approach 1:
The patent integrates noise suppression mechanisms directly into the air guide structure of the air amplifier. The noise suppression chambers and acoustic absorption materials are merged with the existing gas flow path, allowing noise reduction functionality to be incorporated without requiring separate, additional components. This integration maintains air amplification performance while adding noise suppression capability
