Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional farming methods are used to produce food, then food production can meet current demands, but greenhouse gas emissions increase and crop production becomes vulnerable to climate change
Solution Approach 1:
The invention extracts the essential photosynthetic function from whole plants and isolates chloroplasts as the active component. By taking out only the photosynthetic capability and placing it in a controlled microfluidic environment, the system eliminates the need for traditional farming while maintaining glucose production, thereby reducing greenhouse gas emissions associated with agriculture.
Solution Approach 2:
The invention creates an artificial copy of the photosynthesis process by synthesizing chloroplasts in a laboratory setting and reproducing their function within a microfluidic device. This artificial photosynthesis system mimics natural plant photosynthesis to produce glucose without requiring agricultural land, thus decoupling food production from greenhouse gas emissions.
2Productivity
If micro channels are used to contain chloroplasts, then photosynthesis can be controlled efficiently, but chloroplasts may spill out causing loss of substance
Solution Approach 1:
The invention uses filter plugs made of flexible porous material to seal the micro channels. These filter plugs act as flexible barriers that prevent chloroplast escape while allowing nutrient and solution flow, thus maintaining photosynthesis efficiency without chloroplast loss.
Solution Approach 2:
The filter plugs are constructed from porous materials with specific pore sizes that allow small molecules and nutrients to pass through while retaining larger chloroplast structures. This selective permeability enables controlled containment where chloroplasts are prevented from spilling out but essential substances can still diffuse through for photosynthesis.
3Duration of action of stationary object
If continuous injection of saline solution is used to maintain photosynthesis, then photosynthetic activity is sustained, but fluid backflow may occur reducing system reliability
Solution Approach 1:
The filter plugs serve as flexible flow control elements that adapt to pressure changes in the system. During continuous saline solution injection, these flexible filters prevent backflow by conforming to the channel walls and blocking reverse flow paths, thus maintaining reliable unidirectional flow while sustaining long-term photosynthesis.
Solution Approach 2:
The porous structure of the filter plugs allows controlled fluid passage while preventing backflow. The interconnected pores provide pathways for forward flow during injection but close or redirect flow during pressure reversals, ensuring reliable fluid control for sustained photosynthetic activity.
