Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If complex recognition systems with electromechanical elements are used to detect correct positioning, then positioning accuracy can be achieved, but the system reliability deteriorates due to wear and failure of electromechanical components

Engineering Contradiction:

Improvepositioning detection accuracyVSAvoidsystem reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent replaces electromechanical recognition systems with magnetic or optical recognition systems. The magnetic system uses permanent magnets and magnetic sensors to detect positioning without mechanical contact, while the optical system uses light sources and photodetectors to detect positioning through optical fields. This substitution eliminates wear and failure associated with electromechanical components while maintaining positioning detection accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If standalone magnetic or optical recognition systems are used instead of complex electromechanical systems, then device complexity is reduced, but measurement precision may deteriorate

Engineering Contradiction:

Improverecognition system complexityVSAvoidpositioning detection accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent uses magnetic field patterns or optical field patterns as information carriers to represent positioning information. Instead of complex electromechanical sensing, simple magnetic sensors or photodetectors detect these field patterns to determine correct positioning. This copying approach maintains precision while reducing complexity.

Inventive Principle:

Principle #26Copying

3Productivity

If automatic charging is activated upon recognition of correct positioning, then productivity is improved by reducing idle time, but the risk of accidental movement during charging increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by using the recognition system to detect correct positioning before activating charging, and by continuously monitoring positioning during charging. The system prevents charging activation or interrupts charging if incorrect positioning or accidental movement is detected, thereby counteracting the harmful effect of accidental movement while maintaining productivity benefits.

AI summary

Measuring assembly with a measuring apparatus and a recognition system, and recognition method to detect the correct positioning of a removable device such as a comparator to check the shape and/or dimensions of a mechanical part with respect to a stationary part that includes at least one mechanical reference for the removable device. The system comprises a field source disposed in the stationary part that generates a field and a matching element disposed on the removable device that is able to alter the propagation of this field if correctly positioned relative to the field source. A sensor fixed to the stationary part in an appropriate position detects or not the field and generates a resulting detection signal detection or non-detection signal. A processing unit receives the signal generated by the sensor and on the basis of this provides information about the correct or incorrect positioning of the removable device with respect to the stationary part. The recognition system can be of the magnetic or optical type.
