Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible planar support is used to enable curved detector configurations, then adaptability to different geometries is improved, but image distortion and measurement data evaluation accuracy deteriorate
Solution Approach 1:
The patent implements a feedback mechanism by incorporating a shape detection device that continuously monitors the actual position and orientation of the flexible support. This shape information is fed back to an evaluation device that uses it to correct image distortions, thereby maintaining measurement precision despite the flexibility and curvature of the detector.
Solution Approach 2:
The patent introduces an intermediary shape detection device (using Bragg gratings in waveguides) that mediates between the flexible support structure and the image evaluation system. This intermediary captures shape information and transforms it into corrective data, enabling accurate image evaluation even when the detector is curved or deformed.
2Ease of manufacture
If conventional flat X-ray detectors are used, then manufacturing simplicity is improved, but the ability to detect radiation in curved geometries deteriorates
Solution Approach 1:
The patent applies the principle of flexible shells by using a thin, flexible planar support that can be easily manufactured but also deformed into curved configurations. This flexible support maintains the simplicity of manufacturing a flat detector while enabling adaptation to curved geometries through controlled deformation.
Solution Approach 2:
The patent introduces dynamics by making the planar support flexible rather than rigid, allowing it to adapt its shape dynamically to different detection geometries. The support can be bent or deformed as needed, transforming a static flat detector into a dynamic system that can assume various curved configurations while maintaining manufacturing simplicity.
3Ease of operation
If the radiation detector is made freely movable and flexible, then ease of operation is improved, but shape control and image distortion correction become more difficult
Solution Approach 1:
The patent implements self-service by incorporating autonomous shape detection capabilities directly into the flexible support structure. The Bragg grating-based shape detection device automatically monitors and reports the support's configuration without external intervention, enabling the system to self-correct for image distortions and maintain accuracy despite free movement and flexible deformation.
