Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If observer-based video analysis is used to assess coordinated cellular motion, then the assessment can be performed with simple equipment, but the analysis is subjective, slow, and not reproducible
Solution Approach 1:
The patent replaces the mechanical/visual inspection method with an automated image analysis system that uses computational algorithms to objectively measure cellular motion parameters. The system automatically tracks cell positions, calculates motion vectors, and quantifies coordinated motion patterns, eliminating observer subjectivity while maintaining equipment simplicity.
Solution Approach 2:
The system enables self-service analysis by automatically processing images and generating assessments without requiring trained observers. The automated algorithms independently perform motion tracking, coordination analysis, and treatment effect evaluation, making the process reproducible and accessible.
2Reliability
If aggregate electrical property measurements are used to assess cellular motion, then the analysis can be objective, but the technical difficulty is high and throughput is low
Solution Approach 1:
The patent substitutes complex electrophysiological measurements with optical imaging and computer vision techniques. By using microscopy to capture cell motion and automated image processing to analyze it, the system achieves objectivity without the technical complexity and low throughput of electrical measurements.
Solution Approach 2:
The system changes the measurement parameters from electrical properties to optical/motion-based parameters. By tracking positional changes, motion vectors, and coordination patterns from images, the system achieves high throughput while maintaining objective assessment capabilities.
3Measurement precision
If aggregate electrical measurements are used, then the analysis can be performed, but there is poor correlation with cellular motion and it cannot assess coordinated nature of motion
Solution Approach 1:
The patent segments the analysis at the individual cell level rather than using aggregate measurements. By tracking each cell's position and motion independently, then analyzing their coordination patterns, the system preserves detailed information about both individual cell behavior and collective coordination, eliminating information loss.
Solution Approach 2:
The system adds spatial and temporal dimensions to the analysis by capturing and analyzing motion trajectories, coordination patterns, and rhythmic behaviors from image sequences. This dimensional expansion enables assessment of coordinated motion that aggregate electrical measurements cannot detect.
