Solution Overview
Problem
Conventional shock-isolation materials for motor vibrations are difficult to assemble, lead to poor contact, and increase costs, while lacking effective vibration absorption in the base of the stator, necessitating additional assembly processes.
Innovation Solution
A stator structure with two elastic elements providing deformation with multiple degrees of freedom, supporting forces in radial and circumferential directions, and a two-piece base design with a heat dissipation metal plate, enhancing stability and vibration absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shock-isolation materials are added into the assembly structure between the base and the housing cover, then shock isolation effect is improved, but assembly difficulty and time consumption increase
Solution Approach 1:
The shock isolation function is merged with the base structure itself. The elastic elements are integrated into the base, eliminating the need for separate shock-isolation materials and their associated assembly processes. This combines the support function and shock isolation function into a single integrated component.
Solution Approach 2:
The base structure provides its own shock isolation capability through the elastic elements embedded within it. The system serves itself by eliminating the need for external shock-isolation materials, as the base inherently provides the necessary vibration absorption and shock isolation functions.
2Reliability
If shock-isolation materials are installed around the motor, then shock isolation effect is improved, but assembly time and labor cost increase
Solution Approach 1:
The shock isolation function is merged with the base structure itself. The elastic elements are integrated into the base, eliminating the need for separate shock-isolation materials and their associated assembly processes. This combines the support function and shock isolation function into a single integrated component.
