Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional sound-absorbing elements and sound-reflecting wall elements are used, then acoustic effects can be achieved, but construction complexity increases and adaptability decreases
Solution Approach 1:
The patent applies dynamics by making the acoustic element's surface geometry changeable. The element can transform between different three-dimensional configurations (convex, concave, or flat surfaces) to adapt to different acoustic requirements. This dynamic transformation capability allows the same physical element to serve multiple acoustic functions without requiring complex construction measures for each specific application.
Solution Approach 2:
The patent utilizes parameter changes by modifying the geometric parameters of the acoustic element's surface. By changing the curvature radius, surface orientation, and spatial configuration of the protrusions and depressions, the element can control the reflection, scattering, and absorption characteristics of acoustic waves. This allows adaptation to different acoustic requirements through parameter adjustment rather than through complex construction.
2Ease of operation
If traditional acoustic elements are installed, then acoustic functions are provided, but flexibility and ease of application are reduced
Solution Approach 1:
The dynamic transformation capability of the acoustic element enables easy adaptation to different applications. The element can be transformed into different configurations depending on the desired acoustic effect, providing both flexibility in application and ease of operation since the same element can serve multiple purposes through transformation rather than requiring multiple specialized elements.
Solution Approach 2:
The acoustic element is designed with multi-functionality, capable of providing reflection, scattering, and absorption functions through its transformable geometry. A single element design can perform multiple acoustic functions by changing its three-dimensional configuration, eliminating the need for separate specialized elements and simplifying application while maintaining flexibility.
3Manufacturing precision
If complex construction measures are taken, then acoustic requirements can be met, but material usage increases
Solution Approach 1:
The patent applies dimensionality change by transforming a flat two-dimensional panel into a three-dimensional structure with protrusions and depressions. This spatial transformation allows the element to achieve precise acoustic effects through its geometric configuration rather than through material quantity or complex construction layers, reducing material usage while maintaining manufacturing precision for acoustic performance.
