Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the object detection system uses multiple components and complex constitution to achieve comprehensive detection, then the detection capability is improved, but the device size becomes large and difficult to transport
Solution Approach 1:
The detection device is divided into separate functional modules: a ray source assembly with multiple emission positions, a detector assembly with multiple detection units, and a support structure with adjustable arms. Each module can be independently configured and positioned to achieve comprehensive multi-view detection while maintaining a compact overall structure that is easier to transport and deploy.
2Device complexity
If the object detection system uses a single viewing angle to simplify the structure, then the device complexity is reduced, but the risk of missed detections increases
Solution Approach 1:
Multiple detection units and ray sources are merged into a single integrated detection device with a coordinated support structure. The multiple detection units are arranged to simultaneously capture transmission rays from different angles, merging multiple viewing angles into one unified system that reduces overall structural complexity while eliminating missed detections.
Solution Approach 2:
The detection system transitions from single-angle to multi-angle detection by adding spatial dimensionality. Multiple detection units are positioned at different angular positions around the passageway, capturing transmission rays from multiple directions simultaneously. This dimensional expansion enables comprehensive detection of objects passing through the inspection area.
3Manufacturing precision
If the vertical support arm height is fixed to simplify the structure, then the manufacturing precision is improved, but the adaptability to different inspection scenarios is reduced
Solution Approach 1:
The support structure incorporates adjustable-height vertical support arms that can be dynamically reconfigured for different inspection scenarios. The arms feature telescopic or extendable mechanisms allowing the detection device to adapt its height and positioning according to various object sizes and inspection requirements, providing both precision and versatility.
Solution Approach 2:
The vertical support arm height is made variable through mechanical adjustment mechanisms. By changing the height parameter of the support arms, the detection device can accommodate different inspection scenarios, object dimensions, and deployment environments while maintaining structural precision through controlled adjustment mechanisms.
