Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional check technology is used to verify target power adequacy, then power management control can be performed, but the system cannot derive proper target power when inadequacy is found

Engineering Contradiction:
Improvetarget power adequacy verificationVSAvoidtarget power derivation capability
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system implements a feedback mechanism where the adequacy determination unit evaluates whether the target power is adequate based on learned patterns, and this evaluation result feeds back to the target power derivation unit to adjust and improve future target power derivations. This closed-loop feedback enables continuous improvement of target power accuracy while maintaining verification capability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system employs machine learning to enable self-improvement of target power derivation. The adequacy determination unit learns from historical data and verification results, automatically refining its ability to derive proper target power without external intervention. This self-learning mechanism resolves the contradiction by making the system progressively more capable in both verification and derivation functions.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If machine learning is implemented to derive target power, then power allocation accuracy improves, but system complexity increases

Engineering Contradiction:
Improvetarget power determination accuracyVSAvoidsystem structural complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the complex machine learning functionality into distinct modular units: a target power derivation unit that generates initial target power values, and a separate adequacy determination unit that verifies and learns from these values. This segmentation allows the complex ML operations to be distributed across specialized modules, improving accuracy while managing system complexity through functional decomposition.

Inventive Principle:
Principle #1Segmentation
