Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current fluid sensor technology is used, then detection capability is provided, but detection speed and reliability for small quantities over large areas are insufficient
Solution Approach 1:
The detection system is divided into multiple independent sensor nodes distributed across the large area, each capable of detecting small fluid quantities locally. This segmentation allows parallel detection across multiple locations simultaneously, improving both coverage area and detection speed without sacrificing precision at any individual point.
Solution Approach 2:
The system transitions from point-based detection to area-based detection by distributing sensor nodes across a two-dimensional surface. This dimensional expansion enables simultaneous monitoring of large areas while maintaining the ability to detect small fluid quantities through localized voltage changes at each sensor node.
2Area of stationary object
If fluid detection is performed over large areas, then coverage is improved, but detection reliability and consistency decrease
Solution Approach 1:
The large detection area is divided into multiple zones with independent sensor nodes, each maintaining consistent detection conditions locally. This segmentation ensures that reliability and consistency are maintained at each point while the collective system covers large areas, as each sensor node operates independently with stable performance characteristics.
3Measurement precision
If small quantities of fluid are detected, then sensitivity is improved, but detection area coverage is reduced
Solution Approach 1:
Multiple sensor nodes are distributed across the detection area, with each node optimized for detecting small fluid quantities locally. This segmentation allows the system to maintain high sensitivity for small fluid detections at each point while collectively covering large areas through the distributed network of sensitive sensors.
Solution Approach 2:
The system achieves both high sensitivity for small fluid quantities and extensive area coverage by transitioning from a single large sensor to multiple distributed sensor nodes across a two-dimensional plane. Each node provides sensitive detection capability, and their collective arrangement enables broad area monitoring.
