Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional analysis methods (cryoelectron microscopy, three-dimensional distribution analysis) are used, then structural information can be obtained, but the movement and conformational changes of molecules in solution cannot be observed
Solution Approach 1:
The patent changes the measurement parameter from static structural information to dynamic morphological information by using X-ray small angle scattering. This allows observation of molecular movement and conformational changes in solution state, resolving the contradiction between obtaining structural information and capturing dynamic behavior.
Solution Approach 2:
The patent replaces conventional mechanical imaging methods (cryoelectron microscopy) with X-ray scattering techniques. This substitution enables the observation of molecules in their natural solution state rather than frozen or crystallized states, thereby capturing movement and conformational changes that were previously inaccessible.
2Shape
If existing three-dimensional structure analysis techniques are used, then molecular shape can be visualized, but measurement cannot be performed in solution state under target conditions
Solution Approach 1:
The patent makes the analysis technique universal by enabling it to work in solution state under various target conditions. The X-ray small angle scattering method can accommodate different molecular sizes, concentrations, and environmental conditions, providing both shape visualization and movement analysis capabilities simultaneously.
Solution Approach 2:
The patent transitions from two-dimensional or fixed three-dimensional structural analysis to four-dimensional analysis by adding the time dimension for observing conformational changes and movement. This dimensional expansion allows visualization of molecular dynamics in solution rather than static structures.
3Reliability
If comprehensive quality control analysis is performed, then product quality can be ensured, but analysis time becomes excessively long
Solution Approach 1:
The patent performs preliminary morphological analysis to identify conformational changes and movements that indicate quality issues. By detecting these changes early in the production process, the method enables proactive quality control rather than reactive testing, reducing overall analysis time while maintaining reliability.
Solution Approach 2:
The patent enables continuous monitoring of molecular morphology throughout the production process. The X-ray scattering technique can be applied repeatedly to the same sample over time, providing continuous quality feedback without requiring separate analysis steps, thereby reducing total analysis time while ensuring consistent quality control.
