Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed battery management system is used to manage charge and discharge, then the operation mode is simple and reliable, but the system is not intelligent enough and leads to insufficient remaining power during abnormal weather
Solution Approach 1:
The patent transforms the fixed BMS operation mode into a dynamic control system that adjusts charging and discharging strategies based on real-time weather forecasts. The controller dynamically modifies power management parameters according to predicted weather conditions, enabling the system to adapt to different scenarios (abnormal weather, normal weather, extreme weather) while maintaining reliability and preventing insufficient remaining power.
Solution Approach 2:
The patent applies preliminary action by using weather forecast information to predict future power needs and adjust the energy-storage apparatus operation in advance. The controller proactively charges or discharges the battery based on predicted weather conditions before they occur, ensuring sufficient remaining power is maintained even during abnormal weather events, rather than reacting after power becomes insufficient.
2Loss of information
If the user constantly checks electrical energy storage to determine sufficient power, then the user can monitor power status, but the method is inefficient and requires constant user attention
Solution Approach 1:
The patent implements self-service by enabling the energy-storage apparatus to automatically monitor its own power status and make intelligent control decisions without requiring user intervention. The controller continuously tracks remaining power, compares it with predicted power consumption based on weather forecasts, and autonomously adjusts charging/discharging operations, freeing the user from the need to constantly check power status.
Solution Approach 2:
The patent establishes a feedback mechanism where the controller continuously monitors power status, remaining power levels, and weather forecast information, then uses this feedback to automatically adjust the operation mode. The system provides real-time feedback to the user through the terminal device about power status and control actions, eliminating the need for manual checking while keeping the user informed.
3Adaptability or versatility
If the weather forecast information is not utilized, then the system operation is simple, but the system cannot proactively manage power during abnormal weather conditions
Solution Approach 1:
The patent applies universality by integrating multiple functions into the controller: it processes weather forecast information, predicts future power consumption, determines appropriate control strategies, and executes charging/discharging operations. The terminal device also serves multiple roles including displaying power status, showing weather information, and providing user interaction interface. This multi-functionality enables weather-based adaptive control without proportionally increasing overall system complexity.
