Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If thin, porous membranes are used as cell culture supports, then control over cell culture conditions is improved, but structural integrity and strength are compromised
Solution Approach 1:
The patent applies local quality by creating cavities at specific locations on the membrane surface where cells will be cultured. These localized structural modifications provide mechanical support and defined culture environments without compromising the overall thinness and porosity of the membrane. The cavities are strategically positioned to offer strength where needed while maintaining the membrane's general properties for effective cell culture control.
2Quantity of substance
If thin, porous membranes are used to enable parallel culturing of many cells, then reagent consumption is reduced, but the membranes cannot be adapted for specific cell culture requirements
Solution Approach 1:
The patent implements local quality by providing cavities with specific dimensions, shapes, and surface treatments at particular locations on the membrane. These localized features can be tailored to accommodate different cell types and culture requirements, enabling adaptation for specific cell culture applications while maintaining the overall thin membrane structure that reduces reagent consumption.
Solution Approach 2:
The patent applies segmentation by dividing the membrane surface into multiple cavities, each capable of supporting cell culture independently. This segmentation allows different regions of the membrane to be optimized for different cell types or culture conditions, providing adaptability for specific cell culture requirements while maintaining the resource efficiency of a thin membrane structure.
3Quantity of substance
If large volume vessels are used for cell culture, then uniform cell culture conditions are difficult to achieve, but reagent consumption increases significantly
Solution Approach 1:
The patent applies segmentation by dividing the cell culture environment into multiple small cavities on a thin membrane. Each cavity creates a micro-environment that ensures uniform distribution of nutrients and cells, achieving consistent culture conditions across all cavities. This segmented approach allows parallel culturing of many cells with uniform conditions while using minimal reagents compared to large volume vessels.
