Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current detection technologies are used, then detection capability is provided, but location accuracy and response speed are insufficient
Solution Approach 1:
The system divides the detection task into multiple independent detector units distributed in space, each capturing waveform data from different locations. This segmentation enables parallel processing of multiple data streams, improving both location accuracy through spatial distribution and response speed through simultaneous detection across all detectors
Solution Approach 2:
The system transitions from traditional two-dimensional detection to three-dimensional spatial localization by using multiple detectors positioned in three-dimensional space. By calculating intersections of spherical surfaces defined by detector positions and waveform propagation characteristics, the system achieves precise 3D location determination, improving measurement precision while maintaining rapid response
2Measurement precision
If more detectors are deployed to improve location accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
Each detector in the network is designed as a universal, multi-functional unit that can detect waveform emissions from any direction and contribute to location calculations. The detectors use identical hardware and processing logic, allowing the system to scale by simply adding more identical units rather than designing increasingly complex individual components, thus improving location accuracy while controlling device complexity
Solution Approach 2:
The system uses identical copies of the same detector design distributed throughout the detection area. Each detector is a replicated unit with the same sensing capabilities and processing logic, enabling straightforward system expansion and simplifying manufacturing and maintenance while achieving improved location accuracy through increased spatial coverage
