Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple parallel fan radiation beams are used to capture partial images, then the productivity of image capture is improved, but the device complexity increases due to the need for multiple beams and alignment mechanisms
Solution Approach 1:
The imaging process is segmented into multiple partial image captures using parallel fan beams, where each beam captures a specific portion of the scene. This segmentation allows simultaneous capture of multiple regions, improving productivity while the collimator structure manages the complexity through its organized slit arrangement
Solution Approach 2:
The collimator serves multiple functions: it generates parallel fan beams, aligns multiple radiation paths, and defines the geometric structure for stitching. This multi-functionality reduces the need for separate alignment mechanisms, thereby improving productivity without proportionally increasing device complexity
2Manufacturing precision
If complex alignment and stitching procedures are used, then the manufacturing precision of the imaging system is improved, but the loss of time during operation increases
Solution Approach 1:
The collimator is designed with pre-defined slit geometries and spacing that establish the alignment relationships before imaging begins. This preliminary configuration of the collimator structure eliminates the need for complex real-time alignment procedures, achieving high precision while reducing processing time
Solution Approach 2:
The patent replaces complex mechanical alignment systems with a fixed collimator structure that provides geometric alignment through its slit arrangement. This substitution maintains manufacturing precision while significantly reducing the time required for alignment and stitching operations
3Ease of operation
If a collimator with multiple parallel slits is used, then the ease of operation is improved through automated beam generation, but the device complexity increases due to the collimator structure
Solution Approach 1:
The collimator with its multiple parallel slits automatically generates and aligns multiple fan beams without requiring external intervention. The structure serves itself by using its geometric configuration to define beam paths and alignment relationships, improving ease of operation while the complexity is confined to the passive collimator component rather than active control systems
