Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration motors experience stress on joints between the housing and support members due to vibrations in multiple directions, leading to potential breakage and reduced reliability and stability of vibrations.
Innovation Solution
A vibrator support structure with elastic deformation portions and engagement portions that allow for sliding motion during vibrations, reducing stress on joints and enhancing the reliability of the joint between the housing and support members, enabling stable vibrations in two different directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vibrator is supported by rigid support members fixed to the housing, then the vibrator can be stably positioned, but stress concentrates on the joints causing breakage during multi-directional vibrations
Solution Approach 1:
The support member transitions from a rigid structure to one with elastic deformation portions, changing the mechanical parameter of rigidity to flexibility. This allows the support member to absorb vibration stresses through elastic deformation rather than transmitting them to the joints, resolving the contradiction between joint reliability and joint strength
Solution Approach 2:
The support member is designed with movable engagement portions that can slide along the vibrator surface during vibrations. This dynamic capability allows the support member to adapt to multi-directional vibrations while maintaining stable positioning, preventing stress concentration at fixed joints
2Stability of the object's composition
If the support member is fixed rigidly to the housing, then positioning is stable, but the joint breaks under repeated vibration stress
Solution Approach 1:
The engagement portion is designed to slide along the vibrator surface in response to vibrations, providing dynamic adaptation while maintaining stable positioning. This sliding mechanism allows the support member to remain firmly attached to the vibrator while accommodating multi-directional movements without breaking the joint
Solution Approach 2:
The elastic deformation portion acts as a pre-designed cushion that absorbs vibration stresses before they reach the joint. By incorporating this cushioning element in advance, the joint is protected from breakage during repeated vibrations while maintaining positioning stability

AI summary
A vibrator support structure, a vibration motor including the vibrator support structure, and an electronic device including the vibration motor are provided. The vibrator support structure includes a housing, a vibrator, and a first support member. The vibrator is slidable in a first direction D1 and a second direction D2 that crosses the first direction D1. The vibrator is supported within the housing by the first support member, which includes a first deformation portion and a first engagement portion. The first deformation portion undergoes elastic deformation associated with vibrations of the vibrator in the first direction D1. The first engagement portion engages with the vibrator in such a manner that the vibrator produces a sliding motion associated with vibrations of the vibrator in the second direction D2.
