Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual measurements are used to set cutting tool settings, then the operator can adjust the tool settings, but the measurement accuracy is low leading to incorrect settings

Engineering Contradiction:
Improvemanual adjustment capabilityVSAvoidmeasurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces manual mechanical measurement methods with an automated optical measurement system using cameras and image processing. The system captures images of the cutting tool and uses computer vision algorithms to automatically determine geometric parameters, eliminating the need for manual measurements while significantly improving measurement accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cutting tool itself serves as the measurement object, with its geometric features directly captured by the imaging system. The tool's own structure provides the measurement references, eliminating the need for separate measurement devices or manual intervention.

Inventive Principle:
Principle #25Self-service

2Productivity

If incorrect tool settings are used, then the operation can proceed, but the quality of the performed operation decreases

Engineering Contradiction:
