Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibratory devices have a high parts count and low vibration transmission efficiency due to the need for support members and housings, which increase mechanical losses and reduce efficiency.
Innovation Solution
A vibratory device design featuring a single elastic plate with a piezoelectric diaphragm, where the diaphragm is positioned on a vibratory portion spaced parallel to a fixable surface, and a connection portion that allows for increased vibration amplitude, reducing the need for additional components and enhancing vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support member and housing are used to support the elastic plate, then the structural stability is improved, but the parts count increases and vibration transmission efficiency decreases
Solution Approach 1:
The support member and housing are merged into a single integrated housing structure that performs both support and enclosure functions. The elastic plate is directly mounted on the housing without separate support members, reducing parts count while maintaining structural stability through direct mounting and strategic placement of weights on the housing.
2Stability of the object's composition
If a support member and housing are used to support the elastic plate, then the structural stability is improved, but the vibration transmission efficiency decreases due to mechanical losses
Solution Approach 1:
By integrating the support function into the housing itself and eliminating separate support members, the vibration path is shortened and mechanical interfaces are reduced. The elastic plate is directly coupled to the housing, minimizing energy loss at intermediate support points and improving overall vibration transmission efficiency.
3Force
If the piezoelectric diaphragm is positioned to not overlap the fixable portion, then the vibration amplitude is improved, but the structural support is reduced
Solution Approach 1:
The housing structure is designed with locally optimized support regions. The fixable portion provides localized structural support at the mounting interface, while the piezoelectric diaphragm is positioned on the vibratory portion where maximum vibration amplitude is needed. The connection portion and weights provide additional localized support and balance, ensuring structural integrity is maintained despite the non-overlapping arrangement.

AI summary
A vibratory device includes an elastic plate and a piezoelectric diaphragm. The elastic plate includes a fixable portion, a vibratory portion, and a connection portion. The fixable portion is fixed to a fixation member. The vibratory portion is spaced away from a fixable surface of the fixable portion that faces the fixation member and arranged substantially in parallel with the fixable surface. The connection portion connects a first end of the fixable portion in its planar direction and a first end of the vibratory portion in its planar direction. The piezoelectric diaphragm is disposed on a surface of the vibratory portion that is adjacent to the fixable portion. In a direction N normal to the surface of the vibratory portion adjacent to the fixable portion, at least part of the second piezoelectric diaphragm does not overlap the fixable portion.
