Solution Overview
Problem
Existing multifunctional vibrators with elastic members are limited by one-directional deformation, which restricts vibrating amplitude and can cause damage to inner components during falls.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If elastic members are designed to generate deformation only along one direction, then the structure is simple, but the vibrating amplitude is limited and inner components are damaged during falling
Solution Approach 1:
The elastic members are designed with U-shaped arms extending along both X and Y directions, enabling deformation in multiple directions rather than a single direction. This dimensional expansion allows the elastic members to absorb impact forces from various angles during falling, thereby protecting internal components while maintaining structural simplicity
2Ease of manufacture
If elastic members are designed to generate deformation only along one direction, then the manufacturing is simple, but the vibrating amplitude is limited
Solution Approach 1:
The U-shaped arm structure extends in both X and Y directions, allowing the magnetic circuit part to vibrate with larger amplitude in multiple directions. This multi-directional design increases the effective vibrating amplitude while maintaining ease of manufacture through the standardized U-shaped geometry
3Reliability
If elastic members with U-shaped arms extending along both X and Y directions are used, then the vibrating amplitude is enhanced and protection against damage is improved, but the device complexity increases
Solution Approach 1:
The U-shaped arm structure serves multiple functions simultaneously: it provides elastic support, enables multi-directional vibration, and protects against impact damage during falling. This multi-functionality reduces the need for additional protective components, thereby limiting the increase in overall device complexity while achieving enhanced reliability
