Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single gas sensor is used to detect odors, then the device complexity is low, but the ability to detect various types of odors is insufficient
Solution Approach 1:
The gas sensor is divided into multiple sensitive members (first sensitive member, second sensitive member, etc.), each capable of detecting different odor molecules. This segmentation allows the system to detect various types of odors while maintaining relatively simple individual sensor components.
Solution Approach 2:
Each sensitive member is designed with specific sensitivity to different odor molecules, making the multi-member sensor system universally capable of detecting multiple odor types simultaneously. The measuring instrument integrates measurements from all sensitive members to provide comprehensive odor detection.
2Adaptability or versatility
If multiple sensitive members are used to detect various odors, then the odor detection capability is improved, but the measurement complexity increases
Solution Approach 1:
A measuring instrument is introduced as an intermediary component that systematically measures and processes the reactions of multiple sensitive members. This intermediary device simplifies the measurement process by providing a unified interface for collecting and analyzing data from all sensitive members, reducing the complexity of handling multiple sensors.
3Measurement precision
If independent measurement of each sensitive member is performed, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
Each sensitive member is designed to independently react to and measure its specific target odor molecules without requiring complex external processing. The sensitive members self-generate measurable signals that can be directly read by the measuring instrument, eliminating the need for complex signal processing circuits for each individual sensor.
