Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional grid power and combustion processes are used for charging, then power supply requirements are met, but pollutants and harmful emissions are created
Solution Approach 1:
The power station segments power supply into multiple independent sources (photovoltaic panels, wind turbines, generators, and mobile energy storage vehicles) rather than relying on a single conventional grid connection. This segmentation allows the system to meet power supply requirements while eliminating harmful emissions from combustion processes.
Solution Approach 2:
The system employs mobile energy storage vehicles that serve dual functions: they act as energy storage assets and as power processing assets that can import and export power. This multi-functionality allows the system to provide reliable power supply without conventional combustion processes, thereby eliminating pollutants while maintaining reliability.
2Adaptability or versatility
If V2G systems are used with stationary storage, then some power processing functionality is achieved, but mobile components are not effectively utilized as power processing assets
Solution Approach 1:
The patent extends the functionality of mobile energy storage vehicles beyond simple energy storage to include active power processing capabilities. These vehicles can import power from the power station, process it through their onboard systems, and export it back, thereby utilizing mobile components as both storage and processing assets to improve overall system productivity.
Solution Approach 2:
The system dynamically utilizes mobile components by allowing them to move between different operational states (charging, discharging, power processing) and physical locations. This dynamic utilization maximizes the versatility and productivity of mobile assets, transforming them from static storage units to active power processing participants.
3Quantity of substance
If stationary energy storage infrastructure is constructed, then power storage capacity is achieved, but construction time and infrastructure complexity increase
Solution Approach 1:
The patent segments the energy storage infrastructure into distributed mobile units rather than requiring a single large stationary facility. This segmentation allows energy storage capacity to be achieved through multiple smaller mobile vehicles that can be deployed independently, significantly reducing construction time and infrastructure complexity while maintaining total storage capacity.
Solution Approach 2:
The mobile energy storage vehicles utilize their own onboard storage systems and power processing capabilities to provide energy storage services, eliminating the need for extensive external stationary infrastructure. This self-service approach reduces construction time and infrastructure complexity while achieving the required energy storage capacity through the fleet of mobile vehicles.
