Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a gas sensor is designed for detecting a specific gas, then the detection precision for that gas is improved, but the adaptability to detect multiple types of gases deteriorates
Solution Approach 1:
The patent applies parameter changes by utilizing temperature as a controllable parameter to alter the catalytic activity of the catalyst member. By adjusting the temperature of the catalyst member, the device can selectively promote different catalytic reactions, thereby enabling the same sensor to detect multiple types of gases with high precision for each gas type at different temperature conditions.
2Device complexity
If a gas sensor is designed for detecting a specific gas, then the device complexity is reduced, but the adaptability to detect multiple types of gases deteriorates
Solution Approach 1:
The patent implements universality by designing a single gas sensor system that can detect multiple types of gases through the temperature-dependent catalytic action of the catalyst member. The same sensor structure serves multiple detection functions by simply adjusting the temperature parameter, eliminating the need for multiple specialized sensors and reducing overall device complexity.
3Adaptability or versatility
If the temperature of the catalyst member is changed to detect different gases, then the adaptability to detect multiple gases is improved, but the device complexity increases due to temperature control mechanisms
Solution Approach 1:
The patent applies self-service by utilizing the inherent thermal properties of the catalyst member and the natural heat transfer processes. The temperature control is achieved through simple heating mechanisms that leverage the self-heating characteristics of catalytic reactions and thermal conduction, rather than requiring complex active cooling or heating systems. This approach maintains adaptability while minimizing the addition of complex temperature control hardware.
