Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional battery materials are used, then batteries can store electrical energy, but they suffer from low power densities and require toxic or expensive materials
Solution Approach 1:
The patent changes the chemical composition parameters by using nitrogen-containing electron storage materials with specific covalent structures (two-dimensional or three-dimensional), replacing conventional toxic materials with earth-abundant elements while maintaining or improving storage capacity
Solution Approach 2:
The patent employs composite material structures combining nitrogen-containing compounds with specific covalent bonding arrangements to achieve both high electron storage capacity and environmental friendliness, creating a new class of battery materials that overcome the limitations of conventional single-material systems
2Quantity of substance
If conventional batteries are used, then they can provide energy storage, but they have low power densities limiting versatility in mobile applications
Solution Approach 1:
The patent modifies the structural parameters of electron storage materials by introducing specific covalent network structures (2D or 3D) that enable faster ion transport and higher power density while maintaining high energy storage capacity through optimized material composition
3Quantity of substance
If conventional batteries are used, then they can store electrical energy, but they require external voltage for charging and cannot be recharged by solar energy alone
Solution Approach 1:
The patent merges the energy storage function with photovoltaic energy conversion by integrating nitrogen-containing electron storage materials that can directly utilize solar energy for charging, combining two separate systems (battery + solar panel) into a unified autophotorechargeable battery that eliminates the need for external charging infrastructure
Solution Approach 2:
The patent enables the battery to recharge itself using solar energy through the intrinsic properties of nitrogen-containing materials that can be directly excited by light to store electrons, allowing the battery to autonomously convert solar energy into stored electrical energy without requiring external power sources or complex charging circuits
