Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the production speed of organic hydride is increased, then productivity is improved, but Faraday efficiency decreases
Solution Approach 1:
The patent applies dynamics by making the catholyte concentration adjustable and variable during operation. The system transitions from a static concentration setup to a dynamic one where the concentration can be changed based on operating conditions, specifically current density. This allows the system to adapt to different production speeds while maintaining optimal Faraday efficiency at each operating point.
Solution Approach 2:
The patent directly applies parameter changes by varying the concentration of the substance to be hydrogenated in the catholyte based on the current density. When current density increases (higher production speed), the system increases the substance concentration to maintain adequate reaction kinetics and prevent side reactions, thereby preserving Faraday efficiency across different productivity levels.
2Productivity
If the concentration of substance to be hydrogenated is increased, then productivity is improved, but side reactions increase causing Faraday efficiency to decrease
Solution Approach 1:
The patent implements feedback control where the system monitors current density and uses this information to adjust the catholyte concentration accordingly. The control device receives signals about the operating conditions and automatically adjusts the substance concentration to maintain optimal values, preventing both insufficient reaction (at low concentrations) and excessive side reactions (at high concentrations).
Solution Approach 2:
The system dynamically adjusts the substance concentration in the catholyte based on real-time operating conditions. Rather than using a fixed high concentration that always risks side reactions, the concentration is optimized for each operating point, allowing high productivity when needed while minimizing side reactions through appropriate concentration selection.
