Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a tunnel-shaped extension cover is provided to attenuate X-ray leakage, then X-ray leakage is reduced, but the conveyance direction length becomes long
Solution Approach 1:
The shielding gate is divided into multiple segments that can be independently adjusted. Each segment can be positioned to match the contour of different inspection objects, allowing effective X-ray shielding without requiring a long tunnel-shaped extension cover. The segmented structure enables compact design while maintaining shielding effectiveness.
Solution Approach 2:
The shielding gate employs dynamic adjustment mechanisms that allow the gate shape to change according to the inspection object being inspected. This dynamic capability replaces the static, lengthy tunnel structure with an adaptive, compact gate that achieves effective shielding in a shorter conveyance direction length.
2Measurement precision
If a fixed through hole structure is provided for specific inspection objects, then inspection accuracy is improved, but versatility is reduced
Solution Approach 1:
The shielding gate is designed with universal adaptability, capable of adjusting to multiple types of inspection objects with different shapes and sizes. The gate structure incorporates adjustment mechanisms that allow it to configure itself for various object geometries, eliminating the need for specialized fixed holes for each object type while maintaining inspection accuracy.
Solution Approach 2:
The shielding gate utilizes parameter changes in its geometric configuration to adapt to different inspection objects. By modifying parameters such as gate opening size, shape, and position, the system maintains optimal inspection accuracy across diverse object types without requiring fixed specialized structures.
3Measurement precision
If manual adjustment of entrance members is required for different inspection objects, then inspection accuracy is maintained, but operation complexity increases
Solution Approach 1:
The shielding gate incorporates self-adjustment capabilities that automatically configure the gate shape and position based on the detected inspection object. This self-service functionality eliminates the need for manual adjustment by specialized operators, reducing operation complexity while maintaining inspection accuracy through automated adaptation to different object geometries.
