Solution Overview
Problem
Existing acoustic bodies for ceilings are limited in reducing reverberation time, difficult to integrate with installation components, and lack flexibility in installation and modification, while also being prone to water absorption and structural limitations.
Innovation Solution
A two-part acoustic body design with connecting devices allows for flexible assembly and disassembly, enabling easy integration with insulation and piping, and features a sound-conducting recess that forms a Helmholtz resonator to effectively absorb sound frequencies, made from durable plastic to prevent water and concrete penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If acoustic panels are embedded within spatial boundaries using porous materials, then reverberation time is reduced, but installation flexibility and modification capability are limited
Solution Approach 1:
The acoustic body is divided into multiple detachable sections connected by connecting devices, allowing the acoustic panels to be segmented into modular units that can be independently installed, removed, or reconfigured within the ceiling structure without affecting the entire system
Solution Approach 2:
The acoustic panels transition from a fixed embedded design to a dynamic modular system where panels can be easily assembled, disassembled, and repositioned using connecting devices, enabling flexible installation and modification while maintaining acoustic performance
2Object-generated harmful factors
If acoustic panels are made from porous materials, then sound absorption is achieved, but water absorption and structural durability are compromised
Solution Approach 1:
The porous sound-absorbing material is nested within a protective outer shell that prevents water and concrete penetration, allowing the acoustic panel to maintain its sound absorption properties while gaining water resistance and structural durability through the layered construction
3Ease of manufacture
If acoustic panels are designed as single integrated units, then manufacturing is simplified, but integration with installation components becomes difficult
Solution Approach 1:
The modular acoustic panels are designed with universal connecting devices that enable integration with various installation components such as insulation materials, piping, and ceiling structures, allowing a single standardized component to serve multiple functions and compatibility requirements
4Object-generated harmful factors
If acoustic panels are embedded in ceiling structure, then acoustic optimization is achieved, but subsequent installation work is constrained
Solution Approach 1:
The modular acoustic panels are designed to be installed in a predetermined sequence where connecting devices are pre-configured to allow subsequent installation of insulation materials and piping through designated access points, ensuring that acoustic optimization is achieved without compromising future installation accessibility
