Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional acoustic absorbing devices are used, then sound absorption function is provided, but they are difficult to attach to various support members and have limited adaptability
Solution Approach 1:
The acoustic absorbing device is divided into separable components: a housing, an absorbing member, and a silencer that can be selectively assembled and disassembled. This segmentation allows the device to be attached to various support members and adapted to different environments while maintaining ease of installation through modular construction
Solution Approach 2:
The housing is designed with universal attachment features that can be secured to various support members and devices. The modular design with interchangeable absorbing members and silencers provides multi-functionality, allowing the same housing to serve different acoustic absorption needs across different environments
2Adaptability or versatility
If conventional acoustic absorbing devices are used, then sound absorption is provided, but the structure is fixed and cannot be changed according to environmental requirements
Solution Approach 1:
The device is segmented into distinct functional components (housing, absorbing member, silencer) that can be independently selected and assembled. This allows the structure to be changed according to environmental requirements by swapping components, while the segmentation itself manages complexity by making each component relatively simple and standardized
Solution Approach 2:
The device transitions from a fixed structure to a dynamic, reconfigurable structure where absorbing members and silencers can be selectively assembled and disassembled. This dynamic capability allows adaptation to different environmental requirements while maintaining manageable complexity through standardized connection interfaces
3Reliability
If sound transmission paths are increased with multiple components, then noise absorption effectiveness is improved, but the device becomes more complex and harder to assemble
Solution Approach 1:
The absorbing member and silencer are nested within the housing in a compact arrangement. The silencer is positioned to receive sound from the absorbing member, creating an integrated nested structure that provides multiple sound transmission paths and enhances noise absorption effectiveness while minimizing the overall number of separate components and simplifying assembly

Implementation Method 2
an absorbing member (30) engaged into the hood (20) and attached to the hood (20) and including a first gap (48) formed between the hood (20) and the absorbing member (30) for allowing the sound to transmit through the first gap (48) and into the housing (10), the absorbing member (30) including a number of apertures (35) formed in the absorbing member (30) for allowing the sound to transmit through the apertures (35) of the absorbing member (30) and into the housing (10)
Implementation Method 3
a silencer (40) engaged into the absorbing member (30) and attached to the absorbing member (30) and including a second gap (46) formed between the silencer (40) and the absorbing member (30) for allowing the sound to transmit through the second gap (46) and into the housing (10), the silencer (40) including a number of holes (43) formed in the silencer (40) for allowing the sound to transmit through the holes (43) of the silencer (40) and into the housing (10)

AI summary
An acoustic absorbing device includes a housing having a chamber formed by an outer peripheral wall and a bottom wall, a hood engaged into the housing, an absorbing member engaged into the hood, and a silencer engaged into the absorbing member, the silencer and the absorbing member may be selectively attached to the hood or may be easily replaced with the other ones or new or different ones according to different environment. The silencer may include an outer cap extended into or out of the absorbing member. The housing includes one or more couplers for selectively coupling the housing to the other coupling or supporting members.
