Engineering Contradiction Analysis
1Loss of time
If x-ray fiber diffraction analysis is used to detect tumor-specific molecular signatures, then early diagnosis capability is improved, but measurement precision deteriorates due to reproducibility issues
Solution Approach 1:
The patent changes physical parameters of the measurement system including using micro-beam geometry, implementing transverse vibrations at specific frequencies, and controlling inert gas pressure to transform the diffraction measurement conditions. These parameter changes enable consistent detection of molecular signatures across different measurements and samples, resolving the reproducibility issue while maintaining early diagnosis capability
Solution Approach 2:
The patent applies mechanical vibration by transversely oscillating the sample or detector during x-ray diffraction measurement. This vibration separates the diffraction peaks from static background noise and enhances the detectability of subtle molecular changes, thereby improving measurement precision and reproducibility without compromising early diagnosis ability
2Measurement precision
If synchrotron-based x-ray diffraction is used for detailed structural analysis, then measurement precision is improved, but device complexity worsens
Solution Approach 1:
The patent extracts and isolates the essential diffraction measurement function from the complex synchrotron system. By using a simplified x-ray source and focusing on specific diffraction patterns from collagen and other tissue structures, the system achieves sufficient structural analysis precision without requiring the full complexity of synchrotron facilities
Solution Approach 2:
The patent creates a simplified copy of the synchrotron diffraction measurement capability using conventional x-ray sources. By replicating the essential measurement geometry and analysis methods at a reduced scale and complexity level, the system achieves comparable structural analysis precision for diagnostic purposes without the overhead of synchrotron infrastructure

AI summary
An x-ray diffractometer may perform 3D-analysis of collagen tissue of a patient (a human or another animal). The diffractometer includes an oblong housing that may be hinged and that contains an x-ray projector and an x-ray receiver. The analyzed tissue, such as the external ear and skin of a patient, is accommodated between the x-ray projector and the x-ray receiver. The x-ray projector directs an x-ray micro-beam at the patient's tissue. The receiver contains a movable two-dimensional x-ray detector that detects the x-ray micro-beam passed through the analyzed tissue and detects x-rays scattered or diffracted by the analyzed tissue.
