Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a central voltage supply unit is used to provide voltage to all detector elements, then the device complexity is reduced and ease of manufacture is improved, but power losses increase due to long electrical transmission routes
Solution Approach 1:
The detector is divided into multiple segments or regions, each with its own voltage supply unit. This segmentation allows voltage to be supplied over shorter distances to each segment, reducing power losses in the conductors while maintaining the overall simplicity of the system through modular architecture.
Solution Approach 2:
Different regions of the detector are supplied with voltage locally rather than from a single central point. This local quality approach ensures that each region receives adequate voltage with minimal transmission losses, as the conductor length from the supply unit to each detector element is minimized within its local region.
2Area of stationary object
If the detector area is made large to cover more sampling region, then the measurement capability is improved, but power losses increase due to longer electrical transmission routes
Solution Approach 1:
The large detector area is divided into multiple smaller segments, each with its own voltage supply unit. This allows the detector to maintain a large total area for comprehensive sampling while each segment keeps conductor lengths short, thereby reducing power losses despite the overall large coverage area.
Solution Approach 2:
Instead of supplying voltage across the entire large detector area from a single point, the system uses multiple voltage supply units distributed across the detector surface. This dimensional distribution of supply points reduces the maximum transmission distance in any direction, minimizing power losses across the large area.
3Area of stationary object
If voltage is transmitted over long distances to all detector elements, then the device coverage is improved, but noise in the detector operating voltage increases
Solution Approach 1:
The detector is segmented into multiple regions with dedicated voltage supply units, reducing transmission distances and minimizing the introduction of electrical noise into the operating voltage, thereby maintaining high signal detection quality across the entire detector coverage area.
Solution Approach 2:
Each local region receives clean, stable voltage from its own nearby supply unit, preventing the accumulation and transmission of noise over long distances. This local quality control ensures that the detector operating voltage remains low-noise across the entire large-area detector, preserving signal detection reliability.
