Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are disposed in a channel pipe to detect odor components, then detection capability is improved, but fluid flow stability and pressure distribution deteriorate
Solution Approach 1:
The channel is divided into multiple segments with sensors arranged in a matrix pattern (multiple rows and columns) rather than a single linear arrangement. This segmentation allows fluid to flow through multiple parallel paths, maintaining flow stability while enabling detection of odor components at multiple locations simultaneously.
Solution Approach 2:
The sensor arrangement transitions from a one-dimensional linear arrangement in the channel to a two-dimensional matrix pattern. By adding the column dimension perpendicular to the flow direction, the system achieves better pressure distribution and flow stability while maintaining comprehensive odor detection capability across the channel cross-section.
2Measurement precision
If multiple sensors are disposed in a channel pipe to detect odor components, then detection capability is improved, but sensor output stability deteriorates
Solution Approach 1:
The sensor array is segmented into multiple independent sensing elements arranged in a matrix pattern. Each sensor operates independently with stable output, and the collective arrangement provides comprehensive detection without compromising individual sensor performance or output stability.
Solution Approach 2:
Each sensor in the matrix is positioned at a specific location with optimized local characteristics. The sensors are arranged to detect odor components at different positions while maintaining consistent operating conditions, ensuring stable output from each sensor and reducing variations in detection results.
3Volume of moving object
If a compact sensor package is designed, then system size is reduced, but electrode configuration complexity increases
Solution Approach 1:
The electrode groups are merged with the container structure itself rather than being separate components. The container serves dual functions as both the fluid containment structure and the electrode support, integrating multiple functions into a single component to reduce overall package size while managing electrode configuration complexity.
Solution Approach 2:
The container structure is designed to serve multiple functions: containing the fluid, providing structural support, and serving as the substrate for electrode groups. This multi-functionality reduces the need for separate components, compacting the overall system while the electrodes are configured to detect signals from multiple sensors simultaneously.
