Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If parameters of control software are set on the assumption of brand new equipment, then the system is simple and easy to manufacture, but the performance of equipment does not satisfy the determination criterion as time elapses due to wear and aging

Engineering Contradiction:
Improveperformance satisfactionVSAvoidadaptability to equipment degradation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic parameter modification by continuously monitoring equipment state and automatically adjusting control parameters to compensate for wear and aging. The system transitions from static parameters set at manufacturing to dynamic parameters that adapt in real-time to equipment degradation, ensuring performance criteria are maintained throughout the equipment lifecycle.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent directly applies parameter changes by modifying control software parameters based on detected equipment state changes. When equipment performance deviates from determination criteria due to wear, the system calculates and applies parameter adjustments to restore performance, directly addressing the adaptability issue without redesigning the equipment.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If parameters are dynamically switched based on equipment state, then the performance satisfaction is improved, but the device complexity increases

Engineering Contradiction:
Improveperformance satisfactionVSAvoidparameter modification system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the control system to automatically monitor its own equipment state and autonomously modify parameters without external intervention. The determination section evaluates performance criteria and the modification section adjusts parameters automatically, creating a self-regulating system that maintains performance while minimizing operational complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent establishes a feedback loop where equipment state is continuously monitored, performance criteria are evaluated, and parameter modifications are applied based on the evaluation results. This closed-loop feedback mechanism ensures performance satisfaction while managing complexity through systematic, rule-based automatic control rather than manual intervention.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the determination criterion is set in advance, then the ease of operation is improved, but the adaptability to changing equipment condition deteriorates

Engineering Contradiction:
Improvepredetermined criterionVSAvoidadaptability to wear and aging
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies preliminary action by pre-setting determination criteria that define acceptable performance ranges. These criteria are established in advance to guide automatic parameter modification decisions, providing a clear framework that maintains ease of operation while enabling adaptability through automated adjustments when criteria are not met.

Inventive Principle:
Principle #10Preliminary action

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.
