Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If magnetic liquid is arranged between the vibrating component and the housing, then damping effect is improved, but the vibrating component requires additional accommodating space and processing, increasing production complexity and cost
Solution Approach 1:
The damping piece is integrated with the elastic connecting piece through injection molding or extrusion molding, merging two components into one. This eliminates the need for separate accommodating spaces and additional processing steps, resolving the contradiction between achieving damping effect and maintaining simple production processes
Solution Approach 2:
The damping piece acts as an intermediary element between the vibrating component and the elastic connecting piece. It provides the necessary damping function without requiring complex modifications to either the vibrating component or the housing, thus maintaining production simplicity while achieving the desired damping effect
2Object-affected harmful factors
If foam is arranged between the elastic connecting piece and the vibrating component, then damping effect is improved, but additional slots and dispensing operations are required, reducing production efficiency and increasing cost
Solution Approach 1:
The damping piece is merged with the elastic connecting piece through integral forming processes, eliminating the need for separate foam installation steps, slots, and dispensing operations. This integration directly improves production efficiency while maintaining the damping function
Solution Approach 2:
The elastic connecting piece structure itself is designed to incorporate the damping function through the integrated damping piece. This self-service approach eliminates the need for additional components and assembly steps, thereby improving production efficiency and reducing costs
3Force
If driving force is increased to ensure sufficient vibration, then vibration amplitude is improved, but the vibrating component impacts the housing causing failure and impact noise
Solution Approach 1:
The damping piece is positioned between the vibrating component and the elastic connecting piece to provide beforehand cushioning. This prevents the vibrating component from directly impacting the housing during operation, thereby eliminating impact noise and potential failures while allowing sufficient driving force to be applied
