1Reliability

If relearning timing is determined arbitrarily by user, then user control is maintained, but relearning may be delayed causing continued inappropriate outputs

Engineering Contradiction:
Improveoutput accuracyVSAvoidrelearning delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system implements feedback by monitoring output accuracy and detecting anomalies in real-time. When the anomaly detection unit identifies that output accuracy has degraded below a threshold, it automatically triggers relearning. This closed-loop feedback mechanism ensures relearning occurs promptly when needed, resolving the contradiction between maintaining user control and preventing delays.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The learning device performs self-diagnosis and self-upgrade by automatically detecting when relearning is needed and executing the relearning process without user intervention. The control unit monitors its own performance and initiates relearning when anomalies are detected, enabling the system to service itself and maintain high output accuracy without human involvement.

Inventive Principle:
Principle #25Self-service

2Reliability

If relearning is performed automatically upon anomaly detection, then output accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveoutput accuracyVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control unit performs multiple functions: it controls the learning device during normal operation, detects anomalies in output accuracy, and initiates relearning when needed. By making the control unit multi-functional, the system avoids adding separate dedicated components for each function, thereby reducing overall system complexity while maintaining high output accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The anomaly detection unit and control unit are integrated into a unified system where the control unit encompasses both control and anomaly detection capabilities. This merging of functions reduces the number of separate components needed, simplifying the system structure while enabling automatic relearning to maintain output accuracy.

Inventive Principle:
Principle #5Merging (Combining)
