Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If biological production methods using microorganisms are used, then hydrogen gas can be produced, but the production efficiency is low and energy consumption is high
Solution Approach 1:
The patent replaces the biological system (microorganisms) with a chemical system (water-rock reaction). The main reacting device facilitates direct chemical reactions between water and rock samples under controlled temperature and pressure conditions, eliminating the need for biological processes and significantly improving production efficiency while reducing energy consumption.
Solution Approach 2:
The patent changes the reaction parameters by controlling temperature and pressure in the main reacting device. By adjusting these parameters, the water-rock reaction can be optimized to produce hydrogen gas efficiently, transitioning from ambient biological conditions to controlled geochemical conditions that enhance reaction rates and productivity.
2Productivity
If a water-rock reaction system is implemented, then hydrogen production can be evaluated geologically, but the system complexity increases
Solution Approach 1:
The patent divides the water-rock reaction system into distinct functional modules: gas injection device for reactive gas supply, main reacting device for the core reaction, water vapor collecting device for condensate collection, discharging device for reactant discharge, and collecting device for hydrogen capture. This segmentation allows each component to be optimized independently while maintaining overall system functionality.
Solution Approach 2:
The main reacting device serves multiple functions: it contains the rock samples, facilitates water-rock reactions, collects water vapor, and allows for temperature-pressure control. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while achieving comprehensive hydrogen production evaluation.
3Reliability
If pressure control measures are implemented, then safety is improved by preventing excessive pressure accidents, but the device complexity increases
Solution Approach 1:
The pressure relief device is pre-installed in the discharging device to automatically discharge excessive pressure before it reaches dangerous levels. This preliminary safety measure is integrated into the system design, providing automatic protection without requiring complex real-time monitoring or control systems.
Solution Approach 2:
The pressure relief device operates autonomously to maintain safe pressure levels within the main reacting device. It automatically activates when excessive pressure is detected, discharging gas or fluid as needed without human intervention, thereby providing self-regulating safety functionality.
