Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acoustic transducers, particularly those using multiple plates and springs, face difficulties in achieving synchronized resonant vibration across the entire beam, including the tip, due to the challenge of connecting adjacent beams effectively between the fixed end and the tip.
Innovation Solution
The design incorporates an annular base with multiple beams connected via specific connection portions, including a split slit configuration that connects the tips of adjacent beams, allowing for synchronized resonant vibration by reducing internal stress and preventing strong connection forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adjacent beams are connected by springs at a position between the fixed end and the tip, then the beams can be mechanically connected, but it becomes difficult to perform resonant vibration by synchronizing the entire beam including the tip
Solution Approach 1:
The connection structure is segmented into multiple components: the beam, the connection portion with split slit, and the surrounding structure. This segmentation allows the connection portion to be flexible at the slit while maintaining overall structural stability, enabling both mechanical connection and resonant vibration synchronization.
Solution Approach 2:
The split slit configuration changes the mechanical parameters of the connection portion, creating a flexible joint that allows controlled movement. This parameter change enables the connection to accommodate vibrational movements while maintaining structural integrity, resolving the contradiction between connection stability and vibration synchronization.
2Reliability
If the entire beam including the tip is to be synchronized for resonant vibration, then connection strength must be reduced, but this may compromise the mechanical connection between adjacent beams
Solution Approach 1:
The connection portion acts as an intermediary element between adjacent beams. The split slit configuration allows this intermediary to provide flexible coupling that maintains mechanical connection while enabling synchronized resonant vibration of the entire beam structure.
Solution Approach 2:
The connection structure is designed to be dynamic rather than rigid. The split slit allows the connection portion to adapt its stiffness during operation, providing strong connection when needed and flexible movement during resonant vibration, thus resolving the contradiction between connection strength and vibration synchronization.
