Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear vibrating motors face instability and reliability issues due to deformation of spiral springs causing the magnet module to deviate from the intended vibration direction, affecting the motor's performance.
Innovation Solution
A linear vibrating motor design featuring a shell with a magnetic assembly, an elastic module with metal plate elastic members, and a connecting module that ensures the magnet module vibrates stably along a specific direction by providing a strong magnetic flux and elastic deformation, restricting motion in other directions to prevent collisions and enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spiral springs are used to suspend the magnet module, then the magnet module can be suspended and driven to perform linear vibration, but the spiral springs may deform in any direction causing the magnet module to deviate from the appropriate vibration direction
Solution Approach 1:
The elastic module is divided into multiple elastic members (first elastic member and second elastic member) that are arranged in specific directions. Each elastic member is configured to elastically support the magnet assembly in a specific direction, thereby segmenting the support function to prevent unwanted deformation directions and ensure stable linear vibration.
2Ease of operation
If spiral springs are used to suspend the magnet module, then the magnet module can be suspended, but the deformation of spiral springs causes deviation from the intended vibration direction reducing motor performance
Solution Approach 1:
Different elastic members are configured with different orientations and properties to provide targeted elastic support in specific directions. The first elastic member provides support in a first direction while the second elastic member provides support in a second direction, creating local quality differences that guide the magnet assembly to vibrate only in the intended linear direction.
