Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional audio booths use traditional construction methods, then sound isolation is achieved, but the booths become bulky and difficult to transport
Solution Approach 1:
The acoustic booth is divided into modular components including frame sections, wall panels, and ceiling panels that can be assembled and disassembled. This segmentation allows the booth to maintain sound isolation properties while becoming portable and easy to transport, directly resolving the contradiction between sound isolation and transportability.
2Object-generated harmful factors
If conventional audio booths are constructed with soundproofing materials, then noise reduction is achieved, but the booths become heavy and bulky
Solution Approach 1:
The patent employs composite construction combining lightweight frame structures with sound-absorbing panels and acoustic treatment materials. This composite approach achieves effective noise reduction and echo control while keeping the overall weight manageable for portability, resolving the contradiction between noise reduction and booth weight.
3Object-affected harmful factors
If conventional audio booths are designed for sound isolation, then acoustic performance is improved, but assembly becomes complex and difficult
Solution Approach 1:
The booth is constructed from pre-fabricated modular panels and frame sections that can be easily assembled without complex tools or procedures. Each module is designed to simplify assembly while maintaining acoustic performance for echo control, directly addressing the contradiction between echo control and assembly ease.
4Weight of moving object
If conventional audio booths are made portable, then transportability is improved, but sound isolation performance deteriorates
Solution Approach 1:
The patent uses composite construction with lightweight yet acoustically effective materials and designs. The modular panels incorporate sound-absorbing and sound-blocking properties while maintaining reduced weight for portability, resolving the contradiction between portability and sound isolation performance.
