Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a gas detector is equipped with only detection and alarm functions, then the device structure remains simple, but the detector cannot be used effectively in areas with poor lighting

Engineering Contradiction:
Improveoperational capability in poor lighting conditionsVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the lighting device and alarm lamp into a single integrated detection probe assembly. The lighting device is positioned at the front end of the probe while the alarm lamp is integrated within the same probe structure, allowing both illumination and alarm functions to be performed from a single handheld unit without requiring separate lighting equipment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The detection probe is designed to serve multiple functions: gas detection through the sensor, illumination through the lighting device for viewing gas pipelines in dark areas, and alarm indication through the integrated alarm lamp. This multi-functional design allows a single device to replace multiple separate tools.

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

2Ease of operation

If the lighting device and alarm lamp are separated, then each component can be optimized independently, but the overall device size and operational convenience are reduced

Engineering Contradiction:
Improvehandheld operation convenienceVSAvoidprobe structure integration
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The lighting device, alarm lamp, and gas sensor are all integrated into a single handheld detection probe. This consolidation allows the operator to hold one device that provides illumination, detection, and alarm functions simultaneously, greatly improving ease of operation compared to using separate devices.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If the alarm lamp and lighting device use different colors, then the alarm indication is more distinct, but the LED module complexity increases

Engineering Contradiction:
Improvealarm indication clarityVSAvoidLED module design
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent employs color differentiation in the LED module: the alarm lamp emits red light to indicate gas leakage alarms, while the lighting device emits white light for illumination. This color coding provides clear visual distinction between alarm and operational states, ensuring that operators can immediately recognize alarm conditions.

Inventive Principle:
Principle #32Color changes
