VSEngineering Contradiction Analysis

1Productivity

If the production speed of organic hydride is increased, then productivity improves, but Faraday efficiency decreases

Engineering Contradiction:

Improveproduction speed of organic hydrideVSAvoidFaraday efficiency

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The catholyte concentration is made dynamically adjustable rather than fixed. The system can change the concentration of the substance to be hydrogenated in the catholyte based on operating conditions, allowing optimization of both production speed and Faraday efficiency at different operating points

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The concentration of the substance to be hydrogenated in the catholyte is changed as a key parameter. By adjusting this concentration, the system can maintain high Faraday efficiency while achieving high production speeds, resolving the contradiction between productivity and energy efficiency

Inventive Principle:

Principle #35Parameter changes
