Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vibration devices face difficulties in assembly due to the complex S-shaped spring structure, which makes it challenging to weld the spring to the vibrator and housing, and the elastic deformation direction being perpendicular to the welding surface, leading to increased complexity and reduced space utilization.
Innovation Solution
A vibration device with a sheet-like elastic member that is arranged perpendicular to the vibrating direction, featuring a simple structure for easy processing and assembly, where the elastic member is fixed to the vibrator and housing with S-shaped connecting portions, allowing for stable vibration and improved space utilization by eliminating stress on the welding surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an S-shaped spring is used to suspend the vibrator, then the elastic deformation can be achieved, but the structure becomes complicated and difficult to process
Solution Approach 1:
The patent inverts the traditional S-shaped spring structure by using a sheet-like elastic member arranged in a plane perpendicular to the vibrating direction. Instead of bending the spring in the direction of vibration (S-shape), the elastic member is configured with its plane orthogonal to the vibration direction, fundamentally changing the structural approach while maintaining elastic functionality.
Solution Approach 2:
The patent transitions from a one-dimensional S-shaped spring structure to a two-dimensional sheet-like elastic member. The elastic member is arranged in a plane (second dimension) that is perpendicular to the vibrating direction, allowing elastic deformation to occur in a different dimensional space, thereby simplifying the structure and improving processability.
2Stability of the object's composition
If the elastic deformation direction of the spring is perpendicular to the welding surface, then the spring can function, but the welding area becomes difficult to shape and assembly is difficult
Solution Approach 1:
The patent inverts the relationship between the elastic member orientation and the welding surface. Instead of having the elastic deformation direction perpendicular to the welding surface (as in traditional S-shaped springs), the elastic member's plane is arranged perpendicular to the vibrating direction, allowing the welding surface to be parallel to the elastic deformation direction, thus facilitating welding area shaping.
3Stability of the object's composition
If a traditional S-shaped spring is used, then elastic suspension is provided, but space utilization is reduced
Solution Approach 1:
The patent utilizes a two-dimensional sheet-like elastic member arranged in a plane perpendicular to the vibrating direction, thereby optimizing the use of horizontal space within the housing. This dimensional change allows for more efficient space utilization compared to the traditional one-dimensional S-shaped spring that occupies vertical space in the vibrating direction.
