Engineering Contradiction Analysis
1Reliability
If parameters of control software are set on the assumption of brand new equipment, then initial performance satisfies determination criterion, but performance deteriorates over time due to wear and aging
Solution Approach 1:
The patent implements dynamic parameter adjustment by continuously monitoring equipment state through sensors and automatically modifying control software parameters via a parameter modification unit. This transforms the static parameter setting into a dynamic adaptation process that responds to real-time equipment conditions, resolving the contradiction between initial performance and long-term durability
Solution Approach 2:
The system establishes a feedback loop where sensors detect equipment state, the determination criterion unit evaluates whether performance meets standards, and the parameter modification unit adjusts parameters accordingly. This closed-loop feedback mechanism ensures equipment performance continuously satisfies determination criteria throughout its service life, addressing both reliability and duration requirements
2Reliability
If parameters are modified to maintain performance, then determination criterion is satisfied, but system complexity increases
Solution Approach 1:
The control device performs self-diagnosis and self-adjustment by automatically monitoring its own equipment state through integrated sensors and autonomously modifying its control parameters without external intervention. This self-service capability maintains performance reliability while avoiding the complexity of external monitoring and manual adjustment systems
Solution Approach 2:
The patent merges the parameter management unit, determination criterion unit, and parameter modification unit into an integrated control device that combines multiple functions. This consolidation reduces overall system complexity by eliminating separate components for parameter storage, evaluation, and modification while maintaining all necessary functionalities

AI summary
According to the present invention, a controller determines whether the current performance of a piece of equipment satisfies a determination criterion, on the basis of the current state of the equipment, acquired by a sensor. If the controller determines that the current performance of the equipment does not satisfy the determination criterion, the controller calculates a parameter with which the performance of the equipment satisfies the determination criterion, on the basis of the current state of the equipment, acquired by the sensor, and the determination criterion. The controller changes a parameter managed by a storage device to the parameter calculated by the controller.
