Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If infrared laser beam is used for gas detection, then detection capability is improved, but visibility of irradiation position deteriorates
Solution Approach 1:
A visible laser beam is introduced as an intermediary to indicate the irradiation position of the invisible infrared laser beam. The visible laser beam does not participate in gas detection but serves as a visual guide to show users where the infrared beam is directed, resolving the contradiction between using invisible infrared light for detection and needing visibility for user awareness.
2Illumination intensity
If visible laser beam is added to indicate position, then visibility of irradiation position is improved, but device complexity increases
Solution Approach 1:
The visible laser beam generation unit is integrated with the infrared laser beam generation unit, sharing common structural elements such as the laser diode housing, optical path alignment mechanisms, and control electronics. This merging approach allows the visible indicator to be added without proportionally increasing device complexity, as both beams originate from a unified system architecture.
3Measurement precision
If camera device is added to capture irradiation position, then accuracy of position identification is improved, but device complexity increases
Solution Approach 1:
The camera device serves multiple functions: capturing the irradiation position for display, recording gas detection results, and potentially providing visual documentation for maintenance records. This multi-functionality justifies the addition of the camera by making it a versatile component that contributes to several system objectives rather than a single-purpose addition.

AI summary
A gas detection device comprises a detection light emitting device which emits detection light used to detect a gas, a light receiving device which receives a reflected light of the detection light, and a control section which detects the gas on an optical path of the detection light from information on the reflected light received by the light receiving device. The gas detection device comprises a camera device which includes an optical axis generally aligning with an optical axis of the detection light emitted by the detection light emitting device, and a displaying device which displays a camera image taken by the camera device and displays an image showing an irradiated position by the detection light, overlapping the camera image.
