Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a detector arrangement with many detectors is created using a crosswise arrangement of multiple carriers, then the detector density and measurement precision are improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The detector arrangement is segmented into multiple carriers, each carrying a detector field. These carriers are arranged crosswise to form a lattice structure, allowing the system to achieve high detector density while maintaining manageable complexity through modular organization. Each carrier can be independently manufactured and assembled.
Solution Approach 2:
The carriers are designed to be plugged into one another in a nested manner, with insertion slots allowing carriers to be inserted through other carriers. This nesting approach simplifies the overall assembly process by creating a hierarchical structure where smaller units (carriers with detectors) are systematically organized into a larger detector arrangement.
2Ease of manufacture
If carriers are designed with insertion slots for easy assembly, then the ease of manufacture is improved, but the structural strength and stability may be reduced
Solution Approach 1:
The carrier structure is segmented to include dedicated insertion slots that are integrated into the carrier body. These slots are designed with appropriate dimensions and positioning to allow easy plug-in assembly while maintaining sufficient structural strength through optimized slot geometry and carrier material selection.
Solution Approach 2:
The insertion slot functionality is merged directly into the carrier structure itself, rather than being a separate component. This integration allows the carrier to provide both structural support and assembly facilitation through its unified design, eliminating the need for additional fastening mechanisms.
3Ease of operation
If electronics are positioned at a common end of the detector arrangement, then the ease of operation and radiation protection are improved, but the device complexity increases
Solution Approach 1:
The electronics from multiple carriers are merged and concentrated at a common end region of the detector arrangement. This consolidation allows for centralized electronics management, simplified wiring, and improved radiation shielding by locating all sensitive electronic components in a single protected zone, while the carrier configuration remains relatively simple through the crosswise lattice structure.
