Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If electromagnetic radiation detection is used to detect ignition-causing phenomena, then detection capability is provided, but absorption by the medium reduces measurement precision

Engineering Contradiction:
Improvedetection precisionVSAvoidabsorption of electromagnetic radiation
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by measuring absorption at multiple wavelength ranges and using these measurements to adjust the detection threshold dynamically. The system changes the operational parameters (threshold values) based on the measured absorption characteristics of the medium, thereby maintaining detection precision despite varying absorption conditions.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements feedback by continuously measuring the absorption of electromagnetic radiation by the medium and using this information to adjust the detection threshold. The measured absorption values feed back into the detection algorithm, allowing the system to adapt to changing medium conditions and maintain accurate ignition detection.

Inventive Principle:
Principle #23Feedback

2Reliability

If detection threshold is lowered to improve sensitivity, then detection sensitivity increases, but false alarms increase due to absorption effects

Engineering Contradiction:
Improvedetection reliabilityVSAvoidfalse alarms
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent dynamically adjusts the detection threshold parameter based on measured absorption characteristics. Instead of using a fixed threshold, the system calculates appropriate threshold values according to the actual absorption conditions, thereby maintaining high detection reliability while minimizing false alarms caused by absorption effects.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system uses feedback from absorption measurements to continuously optimize the detection threshold. The measured absorption values provide feedback that enables the system to set appropriate threshold levels, preventing both missed detections and false alarms by adapting to the actual medium conditions.

Inventive Principle:
Principle #23Feedback

3Device complexity

If single wavelength detection is used, then device complexity is reduced, but detection accuracy decreases due to varying absorption characteristics across wavelengths

Engineering Contradiction:
Improvedetection system complexityVSAvoidabsorption compensation accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the electromagnetic spectrum into multiple wavelength ranges for separate measurement. By dividing the detection task into multiple wavelength bands, the system can capture the full absorption spectrum characteristics of the medium, enabling accurate absorption compensation while maintaining manageable device complexity through modular measurement approach.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system achieves multi-functionality by using the same detection infrastructure to perform both ignition detection and absorption measurement across multiple wavelength ranges. This universal approach allows the system to gather comprehensive data for both purposes without requiring entirely separate detection systems, thereby balancing complexity and accuracy.

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