Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If detectors are arranged on both sides of the measurement target with large measurement area, then measurement coverage is improved, but installation error and noise susceptibility increase
Solution Approach 1:
The patent merges the detector and amplifier circuit into a single integrated unit, eliminating the need for separate external amplifiers and reducing the number of connections. This integration reduces installation error by ensuring fixed relative positioning and minimizes noise susceptibility by reducing the number of cables and connection points between detectors and processing equipment.
Solution Approach 2:
The patent introduces a rigid frame structure as an intermediary element to support and position the detectors and amplifier circuits. This frame ensures accurate spatial relationships between components, maintaining measurement precision while enabling large-scale deployment. The frame acts as a mediator that stabilizes the entire measurement system.
2Difficulty of detecting and measuring
If dedicated amplifier circuits are used for each detector, then signal processing capability is improved, but electromagnetic noise susceptibility increases
Solution Approach 1:
The patent combines the detector and amplifier circuit into a single integrated module, eliminating the need for separate external amplifier circuits. This integration reduces electromagnetic noise susceptibility by minimizing the number of cables and connection points where noise could enter the system, while maintaining full signal processing capability within the integrated unit.
3Area of stationary object
If large-scale detector arrays are deployed, then measurement coverage is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent divides the measurement system into modular units, each consisting of an integrated detector and amplifier circuit. This segmentation allows the system to be scaled by simply adding more modular units rather than configuring complex interconnections between individual detectors and centralized processing equipment, thereby reducing overall system complexity while maintaining large measurement coverage.
Solution Approach 2:
By merging the detector and amplifier circuit into a single integrated unit, the patent reduces the number of separate components that need to be positioned and connected. This integration simplifies the apparatus configuration by eliminating the need for complex wiring arrangements and reduces installation difficulty while enabling large-scale deployment.
