Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vibration generators for mobile electronic devices require complex manufacturing processes involving multiple molds and pressing steps due to the bending of metal plates, making them difficult to produce efficiently.
Innovation Solution
A vibration generator design that includes a housing, a vibrator, an elastic member with a housing connection portion, a vibrator support portion, and spring portions formed perpendicularly, allowing for simpler manufacturing without the need for multiple molds and pressing processes, using non-magnetic stainless steel components and a magnetic field to generate vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plate spring is formed by bending a metal plate a plurality of times in different directions, then the elastic member can provide the required support and vibration function, but multiple molds and multiple pressing processes are required, making manufacturing difficult
Solution Approach 1:
The elastic member is divided into three distinct functional portions: a housing connection portion, a spring portion, and a vibrator support portion. Each portion serves a specific function and can be formed independently, allowing the housing connection portion and vibrator support portion to be in the same plane while the spring portion extends perpendicularly between them. This segmentation eliminates the need for multiple bending operations and molds.
Solution Approach 2:
The spring portion is configured to extend in a direction approximately perpendicular to the plane containing the housing connection portion and vibrator support portion. This three-dimensional arrangement allows the elastic member to provide the necessary spring function while maintaining a simple planar configuration for the connection and support portions, simplifying manufacturing.
2Shape
If multiple molds and pressing processes are used to form the plate spring, then the elastic member can achieve the required shape, but the manufacturing time and cost increase
Solution Approach 1:
The elastic member geometry is segmented into distinct portions with the housing connection portion and vibrator support portion lying in the same plane and the spring portion extending perpendicularly. This segmentation allows each portion to be formed in a single pressing operation using a single mold, eliminating the need for multiple bending steps and improving manufacturing efficiency.
Solution Approach 2:
The single elastic member structure serves multiple functions: it connects the housing to the vibrator, provides spring support through the perpendicular spring portion, and maintains structural integrity. This multi-functional design achieves the required geometry through a single manufacturing process rather than multiple specialized operations.

AI summary
A vibration generator includes a housing; a vibrator; an elastic member that connects the housing and the vibrator; and a driver that causes the vibrator to vibrate. The elastic member includes a housing connection portion that is connected to the housing, a vibrator support portion that supports the vibrator, and a spring portion that connects the housing connection portion and the vibrator support portion. The housing connection portion and the vibrator support portion are in the same plane. The spring portion is formed so as to be approximately perpendicular to the housing connection portion and the vibrator support portion.
