Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed geometries are used for mounting detectors, then device structure is simplified, but imaging resolution deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transitioning from fixed geometries to movable detectors that can be dynamically positioned. The detector arrangement is no longer static but can be adjusted to optimal positions during imaging, thereby improving imaging resolution while managing device complexity through controlled mobility.
Solution Approach 2:
The patent implements parameter changes by allowing the detector geometry and position to vary rather than remaining fixed. By changing the spatial parameters of detector arrangement, the system achieves improved imaging resolution without requiring overly complex fixed structures.
2Manufacturing precision
If movable detectors are used to improve imaging resolution, then imaging resolution improves, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical positioning systems with a 3D camera-based vision system. Instead of using costly robotic arms with complex mechanics, the system uses optical field measurement to determine detector positions, thereby reducing mechanical complexity while maintaining imaging resolution.
Solution Approach 2:
The patent introduces a 3D camera as an intermediary between the movable detectors and the positioning control system. The camera captures spatial information and provides data for determining detector arrangements, simplifying the overall positioning system while enabling precise imaging resolution.
3Measurement precision
If 3D camera is used to determine detector arrangement, then positioning accuracy improves, but device complexity increases
Solution Approach 1:
The patent uses a 3D camera to create a digital copy or representation of the detector arrangement in space. By capturing the spatial positions of detectors through imaging, the system achieves accurate positioning information without requiring complex mechanical measurement systems, thereby improving positioning accuracy while managing device complexity.
