Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional photovoltaic and energy storage system operates only in charging or discharging mode at any given time, then the system structure is simple, but the system lacks the capability of scheduled charging and discharging based on user requirements
Solution Approach 1:
The patent applies multi-functionality by enabling the inverter and portable power supply to operate in multiple modes simultaneously. The inverter can perform grid connection, charging, and discharging functions, while the portable power supply can simultaneously charge and discharge. This allows the system to provide scheduled charging and discharging capabilities without requiring separate dedicated devices for each function, thus improving adaptability while controlling complexity.
Solution Approach 2:
The patent implements dynamic operation by allowing the system to flexibly switch between different operating modes based on user requirements and real-time conditions. The inverter and portable power supply can dynamically adjust their states (energized/de-energized, charging/discharging) through control instructions received from intelligent apparatuses, enabling scheduled operation while maintaining system simplicity through software-based control rather than hardware reconfiguration.
2Extent of automation
If the inverter and portable power supply are controlled by separate communication modules, then the control functionality is basic, but the system cannot achieve coordinated scheduled charging and discharging
Solution Approach 1:
The patent merges the control functions by having both the inverter and portable power supply communicate with preconfigured intelligent apparatuses that can issue coordinated control instructions. Instead of requiring complex multi-layer communication protocols between multiple controllers, the system combines control authority at the intelligent apparatus level, allowing automated scheduled charging and discharging while keeping the communication structure relatively simple and direct.
