Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional anti-vibration mounts are used to reduce vibration transmission, then vibration isolation is improved, but the mounts deteriorate over time due to prolonged vibration and chemical exposure
Solution Approach 1:
The invention extracts the harmful function of traditional anti-vibration mounts by eliminating them entirely from the system. Instead of using separate elastomeric mounts that deteriorate, the patent integrates vibration damping directly into the spring pack assembly through the stationary node fixing mechanism, removing the component that causes reliability issues while maintaining vibration isolation
Solution Approach 2:
The invention merges the vibration isolation function with the spring pack assembly by fixing the vibrating unit directly to the support surface through the stationary node of the spring pack. This combines the supporting function and vibration damping function into a single integrated system, eliminating the need for separate anti-vibration mounts
2Device complexity
If the vibrating unit is directly fixed to the support surface, then device complexity is reduced, but vibration transmission to the support surface increases
Solution Approach 1:
The invention uses the stationary node of the spring pack as an intermediary element between the vibrating unit and the support surface. By fixing through this specific node where vibration amplitude is minimal, the spring pack acts as a mediator that directly connects the system to the support while inherently damping vibrations, eliminating the need for additional anti-vibration components
3Object-affected harmful factors
If elastomeric materials are used in contact with water and oil for vibration damping, then vibration isolation is achieved, but the materials deteriorate and cause pollution
Solution Approach 1:
The invention extracts and removes the elastomeric vibration damping materials from the system entirely. By using the stationary node fixing method with spring packs, the patent eliminates the need for elastomeric materials that contact water and oil, thereby preventing their deterioration and the resulting pollution in food and pharmaceutical production environments
Solution Approach 2:
The invention changes the material parameter by replacing elastomeric materials with metal spring packs that have inherent vibration damping characteristics through their stationary node. This material substitution eliminates chemical degradation from water and oil exposure while maintaining vibration isolation performance
