Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If X-ray Talbot imaging device is used to capture high-resolution reconstructed images, then measurement precision is improved, but imaging time increases and object vibration/deformation influence worsens
Solution Approach 1:
The object is pre-loaded to the target load before imaging begins. The control unit maintains the load at this target value throughout the imaging process, ensuring the object is already in its final state when high-resolution images are captured, thereby eliminating deformation during imaging.
Solution Approach 2:
The system dynamically adjusts the loading process by applying load during imaging rather than requiring the object to be statically pre-loaded. The control unit modulates the load application in real-time to achieve the target load while capturing images, allowing the object to be in a stable loaded state throughout the imaging sequence.

3Loss of information
If tensile or compressive load is applied to object during imaging, then internal characteristics become visible, but object deformation increases
Solution Approach 1:
The object is pre-loaded to the target load before imaging begins. The control unit maintains the load at this target value throughout the imaging process, ensuring the object is already in its final state when high-resolution images are captured, thereby eliminating deformation during imaging.
Solution Approach 2:
The control unit receives detection results from the X-ray detector and adjusts the load applied to the object in real-time. This feedback mechanism ensures the object maintains the target load while being imaged, allowing internal characteristics to be visualized without excessive deformation.
