Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calculation methods are used to determine optimal operating conditions, then accuracy can be maintained, but time delays occur and productivity decreases
Solution Approach 1:
The patent pre-calculates and stores optimal operating conditions for various vibration states in a lookup table during system initialization or offline processing. When the vibration state changes, the system simply retrieves the pre-computed optimal conditions from the table rather than performing real-time calculations, thus eliminating time delays while maintaining accuracy.
Solution Approach 2:
The patent creates a simplified model or lookup table that copies the essential relationship between vibration states and optimal operating conditions. This copied representation allows for rapid querying and decision-making without requiring complex real-time computations, effectively trading computational complexity for speed.
2Reliability
If complex calculations are performed to optimize operating conditions, then reliability can be improved, but device complexity increases
Solution Approach 1:
The patent segments the continuous control problem into discrete vibration state categories, each with pre-determined optimal operating conditions. By dividing the problem into manageable segments (different vibration states with their respective optimal parameters), the system achieves reliable control without requiring complex continuous optimization algorithms.
Solution Approach 2:
The complex optimization calculations are performed in advance during system setup or offline processing, and the results are stored for rapid retrieval during operation. This preliminary computation phase separates the complexity from the real-time operation, maintaining reliability while simplifying the operational system.
3Productivity
If real-time adjustment of operating conditions is implemented, then productivity improves, but measurement precision requirements increase
Solution Approach 1:
The system pre-defines discrete vibration state thresholds and corresponding optimal operating conditions. Instead of requiring continuous high-precision measurement and real-time optimization, the system uses pre-established thresholds that map vibration states to optimal conditions, enabling rapid response with reduced measurement precision requirements.
