Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple elements are used for accurate detection and temperature correction, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection functions into a single integrated sensor element that can detect both target substances and ambient temperature simultaneously. The single element includes multiple resistance members with different detection characteristics, allowing it to perform both target detection and temperature compensation functions without requiring separate sensor elements, thus reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The sensor element is designed with multi-functional capability where a single element performs multiple detection tasks. The element includes resistance members that can detect different target substances (such as alcohol and organic solvents) as well as ambient temperature, eliminating the need for separate dedicated sensors for each parameter and reducing the overall number of elements required in the system.
2Adaptability or versatility
If multiple elements are used for detecting multiple targets, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple detection capabilities into a single sensor element by incorporating resistance members with different detection characteristics. This single element can detect multiple target substances (such as alcohol, organic solvents, and other gases) along with ambient temperature, thereby achieving high adaptability for detecting multiple targets without requiring multiple separate sensor elements.
Solution Approach 2:
The sensor element is designed with universal detection capability that allows it to respond to various target substances and environmental conditions. By incorporating multiple resistance members with different sensitivity characteristics, the single element can adaptively detect different types of targets, providing versatility without increasing the number of physical elements in the device.
3Measurement precision
If multiple elements are used for temperature correction, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The patent combines temperature detection and target substance detection functions into a single sensor element. The element includes resistance members that simultaneously respond to both temperature changes and target substance presence. By using one element for both temperature correction and target detection, the system eliminates the need for separate powered elements dedicated solely to temperature sensing, thereby reducing overall power consumption while maintaining temperature correction accuracy.
