Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical reducing agents (sodium hydrosulfite, sodium thiosulfate, etc.) are used for producing reduced CoQ10, then the production process can proceed, but the quality of reduced CoQ10 is affected and complex purification is required
Solution Approach 1:
The patent introduces a biological catalyst (enzyme) as an intermediary to mediate the reduction reaction. Instead of using chemical reducing agents that directly reduce CoQ10, the enzyme catalyzes the reduction process through a biological pathway, producing reduced CoQ10 without introducing harmful chemical residues that would compromise quality or require complex purification.
Solution Approach 2:
The patent replaces the chemical reduction mechanism with a biological enzymatic mechanism. The chemical reduction system (using agents like sodium hydrosulfite) is substituted with a biological system (enzyme-catalyzed reduction), fundamentally changing the reaction mechanism to achieve both high productivity and high quality without the drawbacks of chemical methods.
2Productivity
If chemical reducing agents are used for producing reduced CoQ10, then the reaction can proceed, but the production cost increases due to complex purification requirements
Solution Approach 1:
The enzyme acts as a selective intermediary that catalyzes only the desired reduction reaction, avoiding side reactions and byproduct formation. This specificity eliminates the need for complex purification steps, thereby reducing production costs while maintaining high productivity.
Solution Approach 2:
The patent changes the fundamental parameter of the reduction process from chemical to biological. This parameter change transforms the reaction conditions, selectivity, and product purity, thereby simplifying downstream processing and reducing overall manufacturing costs.
3Productivity
If large amounts of reducing agents are used for chemical reduction, then the reduction reaction can proceed, but safety hazards increase
Solution Approach 1:
The patent replaces the chemical reduction system requiring large amounts of reducing agents with a biological enzymatic system. The enzyme catalyzes the reduction reaction with high efficiency at low concentrations, eliminating the safety hazards associated with handling and storing large quantities of chemical reducing agents.
Solution Approach 2:
The enzyme serves as a safe intermediary that enables the reduction reaction to proceed efficiently without requiring hazardous chemical reducing agents. The biological catalyst provides the necessary reactivity while being inherently safer to handle and dispose of compared to chemical reducing agents.
