Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If electric energy prices are fixed uniformly across all charging stations and time periods, then pricing simplicity is maintained, but electric energy waste increases due to inability to optimize usage patterns
Solution Approach 1:
The patent implements dynamic pricing by setting different electric energy prices according to time zones and charging station locations. The management device dynamically adjusts prices based on usage statistics, demand patterns, and time of day, transforming the static pricing system into a flexible one that adapts to changing conditions and reduces energy waste.
Solution Approach 2:
The patent changes the price parameter of electric energy based on multiple factors including time zone, charging station location, and usage statistics. By varying the price parameter dynamically, the system incentivizes optimized charging behavior and reduces overall energy waste without requiring complex hardware modifications.
2Productivity
If electric energy prices are adjusted dynamically based on usage statistics and time zones, then energy utilization efficiency is improved, but pricing calculation complexity increases
Solution Approach 1:
The patent establishes a feedback mechanism where the management device collects usage statistics from charging stations, analyzes demand patterns, and uses this information to adjust pricing. The feedback loop continuously optimizes energy utilization by comparing actual usage with pricing incentives, improving efficiency while keeping calculation complexity manageable through systematic data processing.
Solution Approach 2:
The management device performs multiple functions including collecting usage data, analyzing statistics, determining pricing strategies, and communicating with charging stations. By consolidating these functions in a single multi-functional system, the patent improves energy utilization efficiency without proportionally increasing overall system complexity.
3Loss of energy
If uniform electric energy pricing is applied across all charging stations, then system simplicity is maintained, but energy waste occurs due to lack of location-specific optimization
Solution Approach 1:
The patent applies local quality by setting different electric energy prices for different charging station locations based on their specific usage statistics and demand patterns. Each charging station receives customized pricing that reflects its local characteristics, enabling optimized energy utilization at each location while maintaining overall system coordination.
