Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If artificial photosynthesis systems are used to convert sunlight to chemical energy, then energy storage capability is improved, but energy conversion efficiency remains limited by solar cell efficiency
Solution Approach 1:
The patent implements a dynamic switching mechanism that allows the device to change its operational mode based on real-time conditions. The system can switch between artificial photosynthesis mode (for energy storage when sunlight is abundant) and solar cell mode (for direct electricity generation when power is needed), optimizing both energy storage capability and conversion efficiency under different operating conditions.
2Loss of energy
If solar cells are used to generate electricity directly, then energy conversion efficiency is improved, but energy storage capability is insufficient during power shortages
Solution Approach 1:
The patent designs a multi-functional device that can operate in multiple modes: artificial photosynthesis mode for energy storage, solar cell mode for direct electricity generation, and electrolytic system mode for chemical synthesis. This universal design allows the same device to address both immediate power needs and long-term energy storage requirements, eliminating the need for separate systems.
3Duration of action of moving object
If separate artificial photosynthesis systems and solar cells are installed to handle both energy storage and power generation, then both functions are achieved, but installation area increases
Solution Approach 1:
The patent merges the functions of artificial photosynthesis systems and solar cells into a single integrated device. By combining the photocatalyst components, electrolytic cell, and solar cell structures into one unified system with shared components and a common electrolyte solution, the patent achieves both energy storage and power generation capabilities while significantly reducing the total installation area compared to separate systems.
4Productivity
If electrolytic systems are used for chemical synthesis, then chemical fuel production is improved, but operation during power shortages becomes problematic
Solution Approach 1:
The patent enables the electrolytic system to serve itself by using sunlight as the energy source. The solar cell component generates electricity directly from sunlight, which then powers the electrolytic reactions for chemical fuel production. This self-service capability eliminates the need for external power supplies, allowing the system to operate reliably during power shortages and even thrive in off-grid conditions.
