Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed backscatter detection apparatus is used, then the structure is stable and simple, but the apparatus cannot move to inspect bulky items and cannot adapt to variable locations
Solution Approach 1:
The patent transforms the fixed detection apparatus into a mobile system by mounting the backscatter detection imaging apparatus on a mobile platform with servo mechanisms. This enables the system to dynamically move to different locations and adjust its position relative to items being inspected, resolving the contradiction between structural simplicity and adaptability to variable locations.
Solution Approach 2:
The mobile platform with servo mechanisms provides multi-functionality by enabling both transportation to variable locations and precise positioning adjustments. This universal design allows the same system to handle diverse inspection scenarios including bulky items, irregularly stored items, and items at different locations, thereby improving adaptability without requiring multiple separate systems.
2Adaptability or versatility
If items are moved on a conveyor belt for inspection, then the detection process is standardized, but bulky and heavy items become difficult to carry and move
Solution Approach 1:
Instead of moving items to the detection apparatus as in conventional conveyor belt systems, this patent inverts the approach by moving the detection apparatus to the items. The mobile platform carries the backscatter detection imaging apparatus to the location of bulky items, eliminating the need to transport heavy items and making inspection of difficult-to-move objects practical and efficient.
3Measurement precision
If the distance between the apparatus and item is fixed, then the system structure is simple, but the imaging quality cannot be optimized for items of different sizes and placements
Solution Approach 1:
The servo mechanisms enable dynamic adjustment of the distance between the backscatter detection imaging apparatus and items being inspected. This dynamic positioning capability allows the system to optimize imaging quality for items of different sizes, shapes, and placements by adjusting the detection distance in real-time, resolving the contradiction between fixed simple structure and optimized measurement precision.
Solution Approach 2:
The system changes the physical parameter of detection distance through servo mechanism control. By adjusting this parameter based on item characteristics, the system optimizes imaging quality for different inspection scenarios without requiring complex mechanical reconfiguration, thereby improving measurement precision with moderate complexity increase.
4Measurement precision
If the irradiation intensity is fixed, then the system operation is simple, but the imaging quality cannot be dynamically adjusted according to detection needs
Solution Approach 1:
The system dynamically adjusts the irradiation intensity parameter based on detection needs and item characteristics. This parameter change capability allows optimization of imaging quality by modifying the X-ray irradiation level to match the specific inspection requirements, resolving the contradiction between operational simplicity and measurement precision through intelligent control.
