Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional secondary battery supply systems only provide basic charging facility information, then the system is simple and easy to operate, but users cannot efficiently select the most suitable battery station for their needs
Solution Approach 1:
The patent segments the battery station selection process into multiple independent information components: required charge amount, remaining battery charge, charging speed, and exchange completion time. Each component is calculated and presented separately, allowing users to comprehensively evaluate different battery stations without overwhelming them with a single complex metric.
Solution Approach 2:
The system performs preliminary calculations of exchange completion time before the user makes a selection. By pre-calculating this critical information based on current battery charge levels and charging speeds, the system enables users to make informed decisions about which battery station will complete their exchange fastest, rather than discovering this information too late.
2Productivity
If the system calculates and presents exchange completion time for multiple battery stations, then users can make efficient selections, but the device complexity increases
Solution Approach 1:
The battery stations autonomously provide their own operational data (remaining battery charge, charging speed) to the reservation device through their information provision components. This self-service approach eliminates the need for complex centralized monitoring systems, as each station independently reports its status, simplifying the overall device architecture while enabling comprehensive comparisons.
Solution Approach 2:
The system implements a feedback loop where battery stations continuously report their charge levels and charging speeds to the reservation device. This real-time feedback enables dynamic recalculation of exchange completion times, allowing the system to maintain high productivity by always presenting users with current, accurate information about which station will complete their exchange fastest.
3Measurement precision
If the system collects real-time data from multiple battery stations including charge levels and charging speeds, then accurate exchange completion time can be calculated, but information acquisition complexity increases
Solution Approach 1:
The reservation device is designed with universal information acquisition capabilities that can interface with multiple different battery station types through standardized protocols. The device handles various data types (charge levels, charging speeds, battery capacities) through a unified processing framework, reducing complexity by avoiding the need for station-specific customization while maintaining high measurement precision across diverse stations.
