Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If charging/discharging is performed without considering efficiency differences, then operation is simpler, but electric power losses increase
Solution Approach 1:
The patent applies parameter changes by considering charging/discharging efficiency as a key parameter in the management method. The control device selects charging/discharging systems based on their efficiency parameters, prioritizing systems with higher efficiency to minimize electric power losses during charging and discharging operations.
Solution Approach 2:
The patent implements dynamics by dynamically selecting and switching between different charging/discharging systems based on real-time efficiency considerations. The control device adaptively determines which system to use for charging or discharging electricity, optimizing performance based on varying efficiency conditions of available systems.
2Loss of energy
If charging/discharging plans are set without considering generation schemes, then management is simpler, but electric power efficiency deteriorates
Solution Approach 1:
The patent applies parameter changes by incorporating electric power generation scheme characteristics into the charging/discharging plan formulation. The control device considers parameters such as renewable energy source types and generation patterns when creating optimization plans, thereby improving electric power efficiency while accounting for different generation schemes.
Solution Approach 2:
The patent implements local quality by tailoring charging/discharging plans to specific local conditions of different electric power supply systems. Each plan is customized according to the particular generation scheme and efficiency characteristics of the involved systems, rather than applying a uniform approach.
3Measurement precision
If accumulated electricity is not corrected by measurement, then measurement and correction processes are eliminated, but accuracy of electricity amount calculation deteriorates
Solution Approach 1:
The patent applies feedback by implementing a measurement and correction mechanism where the actual accumulated electricity amount is measured and used to verify and adjust the calculated amount. The control device compares the calculated accumulated electricity with measured values and performs corrections based on the differences, ensuring high accuracy through continuous feedback.
Solution Approach 2:
The patent replaces direct continuous measurement with a calculation-based approach supplemented by periodic measurement and correction. Instead of relying solely on complex continuous monitoring systems, the invention uses mathematical calculations of charged and discharged amounts, corrected by occasional measurements, thereby reducing overall system complexity while maintaining precision.
