Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a traditional near infrared laser radiation measurement scheme rotates a laser source to capture radiation distribution at multiple angles, then measurement completeness is improved, but detection time increases significantly and detection efficiency decreases

Engineering Contradiction:

Improvemeasurement completenessVSAvoiddetection time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

Instead of rotating the laser source to capture radiation at different angles, the patent inverts the approach by keeping the laser source stationary and rotating the photoelectric detector around the target object. This allows the detector to capture radiation distribution at multiple angles simultaneously without requiring multiple sequential measurements, thereby reducing detection time while maintaining measurement completeness

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transitions from a one-dimensional sequential angular measurement approach to a two-dimensional simultaneous measurement approach. By arranging the photoelectric detector to rotate around the target object in a circular path, the system captures radiation distribution data across multiple angles concurrently, effectively adding a spatial dimension to the measurement process and eliminating the time penalty associated with sequential angular scanning

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Measurement precision

If thousands of rotations are performed to capture radiation distribution of all required angles, then data completeness is improved, but detection efficiency and productivity decrease

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent implements continuous useful action by having the photoelectric detector rotate continuously around the target object in a single circular path, capturing radiation distribution data at all required angles in one uninterrupted motion. This eliminates the need for thousands of discrete rotations, maintaining complete angular coverage while dramatically improving detection efficiency and productivity through a single continuous measurement cycle

Inventive Principle:

3Measurement precision

If angular rotation measurement is used to evaluate radiation strength at every angle, then measurement accuracy is improved, but data gaps occur between rotations and measurement reliability decreases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent applies preliminary action by pre-positioning the photoelectric detector on a rotational path around the target object before measurement begins. The detector is configured to continuously scan all angular positions in a predetermined circular trajectory, ensuring that no angular gaps occur during data collection. This preliminary setup guarantees complete angular coverage and continuous data collection, eliminating the reliability issues associated with gaps between discrete rotations
