Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mass block is fixed on the vibrating diaphragm to realize sound transmission function, then the sound transmission function is improved, but the fixed end of the vibrating diaphragm is prone to material fatigue due to stress concentration
Solution Approach 1:
The patent divides the elastic element into multiple regions with different deformation characteristics: a connection region for supporting the mass element and preprocessing regions with greater deformation quantities. This segmentation allows stress to be distributed across different zones rather than concentrated at the fixed end, resolving the contradiction between maintaining sound transmission function and preventing material fatigue.
Solution Approach 2:
The patent applies local quality by creating regions with different mechanical properties within the elastic element. The preprocessing regions are designed to have greater deformation quantities compared to other regions, allowing these specific areas to absorb stress while the connection region maintains structural integrity for supporting the mass element during vibration.
2Reliability
If the elastic element has high deformability to reduce stress concentration, then the reliability is improved, but the vibration displacement needs to be enhanced
Solution Approach 1:
The patent changes the deformation parameters of different regions of the elastic element. By designing preprocessing regions with greater deformation quantities and the connection region with appropriate stiffness, the system achieves both reduced stress concentration and sufficient vibration displacement. The parameter optimization allows the elastic element to deform adequately for sound transmission while distributing stress to prevent fatigue.
