Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional active damping systems are applied to objects with complex vibration modes or unknown rigidity, then the system requires extensive manual analysis and configuration processes, but this increases the time and complexity required for system setup and application
Solution Approach 1:
The system automatically determines the optimal configuration of sensors and actuators by having the object itself provide vibration data through its natural response to actuator excitation. The configuration determination unit processes this data to automatically calculate the necessary sensor and actuator arrangement, eliminating the need for external expert analysis and manual configuration processes.
Solution Approach 2:
The system performs preliminary excitation of the object using actuators to generate vibration data before final system deployment. By conducting this preliminary measurement and analysis phase, the system pre-determines the optimal configuration, allowing for rapid deployment without extensive on-site analysis time.
2Reliability
If manual analysis and configuration processes are used to determine sensor and actuator arrangement, then the system can achieve accurate damping performance, but the number of processes increases and reduces productivity
Solution Approach 1:
The system replaces manual mechanical analysis processes with automated computational processing. The configuration determination unit uses algorithms to process vibration data and automatically calculate optimal sensor and actuator configurations, substituting expert manual analysis with automated computational methods that maintain accuracy while dramatically reducing time requirements.
Solution Approach 2:
The configuration determination unit serves as an intermediary between the vibration data collection and the final system deployment. This intermediary component automatically processes the raw vibration data, performs the necessary calculations, and generates the optimal configuration without requiring manual intervention, thereby bridging the gap between data collection and system deployment efficiently.
3Reliability
If the system requires knowledge of mechanism characteristics and rigidity for configuration, then the damping can be optimized, but this increases the complexity of the application process for objects with unknown properties
Solution Approach 1:
The system eliminates the need for external knowledge about object properties by having the object itself reveal its characteristics through vibration response. The configuration determination unit extracts mechanism characteristics and rigidity information directly from the vibration data generated during the measurement process, allowing the system to self-determine the optimal configuration without requiring pre-existing knowledge or complex manual analysis.
4Reliability
If extensive configuration analysis is performed, then the sensor and actuator arrangement can be optimized, but this increases the number of processes and reduces ease of operation
Solution Approach 1:
The system replaces complex manual configuration analysis with automated computational processing. The configuration determination unit automatically performs the optimization calculations based on vibration data, substituting what would otherwise require extensive manual analysis and expert knowledge with a straightforward automated process that simplifies operation while maintaining optimization benefits.
