Magnetic Vibration Generator Layout for Compact Lateral Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration generators face an issue of increased size in the vibration direction, which is undesirable for compact designs.
Innovation Solution
The vibration generator incorporates a fixed-side member, a movable-side member, and an elastic support that includes left and right elastic supports with specific deforming and standing portions, allowing the movable-side member to vibrate in a left-right direction without interfering with the deforming portions, and utilizes a driver with fixed-side and movable-side magnetic field generators to control vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional plate spring elastic members are used on left and right sides of the movable part, then the vibration generator can maintain structural simplicity, but the size in the vibration direction increases
Solution Approach 1:
The elastic support is divided into multiple functional portions: a deforming portion that bends during vibration and a standing portion that remains substantially upright. This segmentation allows the elastic support to provide necessary mechanical function while reducing the overall size in the vibration direction, as the deforming portion handles the vibration accommodation rather than requiring extended plate spring structures on both sides.
Solution Approach 2:
The elastic support transitions from a conventional two-dimensional plate spring configuration to a three-dimensional structure with distinct deforming and standing portions. The standing portion extends in the vertical direction while the deforming portion handles the vibration direction, effectively using vertical space to reduce the horizontal footprint in the vibration direction.
2Volume of moving object
If the movable-side member is positioned to avoid interfering with the deforming portion during vibration, then the amplitude and volume of the movable-side member can be increased, but the spatial arrangement becomes more complex
Solution Approach 1:
The elastic support has different functional zones: the deforming portion is designed to bend and accommodate vibration movement, while the standing portion maintains a substantial upright orientation. This local differentiation of functional qualities allows the movable-side member to be positioned in the upper region away from the deforming portion's vibration path, enabling increased amplitude and volume without complex spatial arrangements.
3Length of moving object
If the right deforming portion extends in the front-rear direction with length greater than the standing portion, then the vibration generator achieves miniaturization in the left-right direction, but the front-rear dimension increases
Solution Approach 1:
The right elastic support features an asymmetric configuration where the deforming portion extends in the front-rear direction with a length greater than that of the standing portion. This asymmetric design strategically allocates space: the longer deforming portion handles the vibration accommodation in the front-rear direction, enabling miniaturization in the left-right direction while accepting increased front-rear dimension.

Function Achieved in This Case
This configuration enables miniaturization of the vibration generator in the left-right direction while maintaining vibration power, allowing for increased amplitude and volume of the movable-side member, and reduces the overall size in the vibration direction.
