Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional microscopic cell counting methods are used, then cell growth measurement is achieved, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical cell counting methods with automated image analysis systems that capture microphotographs and use computational algorithms to count and measure cells, eliminating labor-intensive manual operations while maintaining measurement accuracy
Solution Approach 2:
The patent creates optical copies (microphotographs) of cell cultures that can be analyzed repeatedly without additional time investment, allowing multiple measurements and statistical analyses from a single image capture event
2Measurement precision
If AFM probe tips are used to measure cell stiffness, then cell property measurement is achieved, but the cost increases significantly
Solution Approach 1:
The patent replaces expensive, disposable AFM probe tips with reusable optical imaging components and software-based analysis tools, achieving comparable measurement capabilities through non-contact optical methods that do not require consumable probes
Solution Approach 2:
The patent substitutes mechanical contact-based AFM measurement with optical field-based imaging and analysis, eliminating the need for physical probe tips and their associated costs while maintaining measurement precision through non-invasive optical techniques
3Measurement precision
If invasive or destructive methods are used for cell analysis, then measurement is achieved, but the cell culture is sacrificed and cannot be monitored continuously
Solution Approach 1:
The patent enables continuous, non-invasive monitoring of cell cultures over time using repeated optical imaging, allowing the same cell culture to be monitored throughout its growth cycle without sacrifice, thereby enabling longitudinal studies and increasing overall monitoring throughput
Solution Approach 2:
The patent replaces invasive mechanical measurement methods with non-contact optical imaging techniques that do not damage or sacrifice the cell culture, allowing repeated measurements on the same samples to improve statistical sampling and monitoring efficiency
