Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rigid planar detectors are used, then manufacturing and deployment are simplified, but spatial resolution and flexibility are limited
Solution Approach 1:
The detector is divided into multiple independently movable detector tiles that can be segmented and reconfigured. Each tile can be independently positioned and oriented to optimize spatial resolution for different imaging tasks while maintaining manufacturing simplicity through modular design.
Solution Approach 2:
The detector transitions from a static rigid planar structure to a dynamic reconfigurable array of movable tiles. The tiles can change position and orientation dynamically to adapt to different imaging requirements, improving spatial resolution and flexibility without complicating manufacturing through standard modular components.
2Device complexity
If rigid planar detectors are used, then system structure is simplified, but adaptability to different imaging tasks is reduced
Solution Approach 1:
The detector system is segmented into multiple independent tiles that can be individually positioned and oriented. This modular segmentation allows the system to adapt to different imaging tasks by reconfiguring the tile arrangement while maintaining relatively simple structural design through standardized interfaces and components.
Solution Approach 2:
The detector system transitions from a fixed static structure to a dynamic reconfigurable arrangement of movable tiles. The tiles can be repositioned and reoriented to optimize performance for various imaging tasks, enhancing versatility without significantly increasing overall system complexity through modular architecture.
3Ease of operation
If fixed shape detectors are deployed, then deployment is simplified, but flexibility for optimizing imaging performance is limited
Solution Approach 1:
The detector is segmented into multiple tiles with standardized interfaces and mounting mechanisms. This segmentation allows for simple initial deployment while enabling subsequent reconfiguration by individually adjusting tile positions and orientations to optimize imaging performance for different clinical applications.
Solution Approach 2:
The detector system evolves from a fixed deployment configuration to a dynamic reconfigurable arrangement. The movable tiles can be adjusted after initial deployment to optimize imaging performance for various tasks, maintaining ease of operation through standardized mechanisms while significantly improving adaptability.
