Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple enzymes and cofactors are used in enzymatic bioelectrocatalysis, then the production of commodities such as formate can be achieved, but the system complexity increases and control becomes difficult
Solution Approach 1:
The patent divides the complex multi-enzyme system into separate reactor cells, each dedicated to a specific enzymatic reaction. By segmenting the overall production process into discrete units with single enzymes or defined enzyme combinations, the system becomes easier to control while maintaining productivity. Each reactor cell can be independently optimized and manipulated.
Solution Approach 2:
The patent introduces electrode surfaces as intermediaries to facilitate electron transfer between enzymes and the external circuit. This mediator approach simplifies the system by providing a controlled interface for electron exchange, reducing the need for complex cofactor management and enabling direct electrochemical control of enzymatic reactions.
2Productivity
If multiple enzymes and cofactors are used in enzymatic bioelectrocatalysis, then the production of commodities such as formate can be achieved, but manipulation and control of reactions becomes difficult
Solution Approach 1:
By separating the multi-enzyme system into individual reactor cells, each handling a specific reaction step, the patent makes manipulation and control straightforward. Operators can independently adjust parameters for each reactor without affecting the entire system, significantly improving ease of operation while maintaining product production capability.
Solution Approach 2:
The patent enables easy control by allowing independent parameter adjustment in each reactor cell. Electrophysiological parameters such as voltage, current, and potential can be modified for individual reactors, providing precise control over enzymatic reactions without the complexity of managing multiple parameters in a single integrated system.
3Reliability
If enzyme is immobilized to surface with electrode surface linker, then electron transfer control is improved, but the device structure becomes more complex
Solution Approach 1:
The electrode surface linker acts as an intermediary component that simplifies electron transfer control. This mediator provides a standardized interface between the enzyme and electrode, ensuring reliable electron transfer while keeping the overall structure manageable through modular design.
Solution Approach 2:
The electrode surface linker serves multiple functions: it anchors the enzyme to the electrode surface, facilitates electron transfer, and provides a standardized interface for enzyme attachment. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while improving electron transfer control.
