Engineering Contradictions & Design Principles
Engineering 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
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.
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.
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
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.
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
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.

AI summary
A gas detector includes a gas detector body; the gas detector body includes a detection probe, a gas detector housing, and a universal shaped tube. An end of the universal shaped tube is connected with the gas detector housing, the other end of the universal shaped tube is connected with the detection probe, and the detection probe is internally integrated with a sensor used to detect a leakage gas, an alarm lamp used for an alarm indication when the leakage gas is detected, and a lighting device used to illuminate. According to the gas detector, an extending portion of the universal shaped tube is provided with the protection probe, and the alarm lamp and the lighting device are added therein, realizing the alarm indication, and being used to illuminate as a searchlight in an area with poor lighting of a gas pipeline during non-alarm.
