Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust stop device is designed to limit deflection movements of damper masses, then the reliability of limiting relative movements is improved, but the device complexity and susceptibility to damage from excessive torque shocks increases
Solution Approach 1:
The patent extracts the function of limiting relative movements from a complex robust stop device and transfers it to the frictional connection between the damper mass carrier and housing. By utilizing friction force generated through the clamping device, the system achieves effective limitation of damper mass deflection without requiring a separate robust stop device, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The patent introduces friction force as an intermediary mechanism between the damper mass carrier and housing. The friction force, generated through the clamping device acting on the damper mass carrier, serves as a mediator that limits relative movements of damper masses without requiring direct mechanical contact of robust stop devices, thus reducing complexity while maintaining effectiveness
2Ease of manufacture
If a clamping device is used to create static friction between housing parts and damper mass carrier, then the ease of manufacture and compactness is improved, but the ability to handle excessive torque shocks without damage may be worsened
Solution Approach 1:
The patent changes the parameter of friction force by using a clamping device to generate static friction between the damper mass carrier and housing. This friction force can adaptively respond to torque variations, providing sufficient resistance to excessive torque shocks while maintaining ease of manufacture and compact design through the simple clamping mechanism
