Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If lead-acid batteries are used for power bridging, then cost is reduced, but life-span is shortened and temperature control requirements increase
Solution Approach 1:
The patent changes the chemical composition parameters of the electrochemical cell by incorporating transition metal cyanide coordination compounds (TMCCCs) into the electrode structures. This compositional parameter change enables the cell to achieve both cost-effectiveness and extended life-span simultaneously, resolving the contradiction between using inexpensive lead-acid batteries and achieving long service life.
2Reliability
If ultra-capacitors are used for power bridging, then cycle life and power capability are improved, but cost increases significantly
Solution Approach 1:
The patent employs composite electrode materials that combine transition metal cyanide coordination compounds with conventional electrode structures. This composite approach enables the electrochemical cell to achieve ultra-capacitor-like cycle life and power capability while maintaining cost-effectiveness, thereby resolving the contradiction between high reliability and low cost.
3Duration of action of stationary object
If flywheels are used for power bridging, then life-span is extended, but immediate response capability is reduced due to transfer switch delays
Solution Approach 1:
The electrochemical cell with TMCCC electrodes is designed to activate immediately upon power failure without requiring external control systems or transfer switches. The cell's intrinsic electrochemical properties enable it to self-start and provide power bridging instantly, resolving the contradiction between extended life-span and immediate response capability.
4Reliability
If conventional power bridging systems are used, then basic power support is provided, but scalability and adaptability to different configurations are limited
Solution Approach 1:
The patent designs the electrochemical cell as a modular unit with standardized terminals and configurations that can be easily segmented and reconfigured. Multiple cells can be connected in series or parallel to scale the system according to specific power requirements, enabling both reliable power support and high adaptability to different application scenarios.
