Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed battery voltage threshold is used in existing systems, then the system structure is simple, but the system cannot adapt to different environmental conditions and locations
Solution Approach 1:
The patent implements a programmable battery voltage threshold system that allows the threshold to be dynamically adjusted based on environmental conditions, location, and vehicle settings. The computing module stores and retrieves different voltage threshold values from memory, enabling the system to adapt to varying operational conditions rather than using a fixed threshold.
Solution Approach 2:
The system changes the voltage threshold parameter dynamically based on environmental factors and operational conditions. By storing multiple voltage threshold values in memory and selecting appropriate values based on current conditions, the system achieves adaptability without requiring complex real-time calculations or sensor integration.
2Productivity
If manual monitoring and recharging procedures are required, then the system is simple, but the operational efficiency and battery maintenance are reduced
Solution Approach 1:
The system performs automatic monitoring of battery voltage and self-initiates engine starting sequences when voltage thresholds are reached. The computing module continuously monitors battery voltage, compares it against stored thresholds, and automatically triggers the ignition system to recharge the battery, eliminating the need for manual intervention while maintaining simple operational procedures.
Solution Approach 2:
The system implements continuous feedback monitoring of battery voltage levels and automatically responds by initiating engine starts when thresholds are breached. This closed-loop feedback mechanism ensures the battery is recharged before complete depletion occurs, improving operational efficiency without requiring complex control algorithms.
3Reliability
If the engine is started frequently to recharge the battery, then the battery charge is maintained, but the energy consumption and mechanical wear increase
Solution Approach 1:
The system proactively starts the engine before the battery is completely depleted by monitoring voltage levels and triggering restart sequences at predetermined thresholds. This preliminary action prevents complete battery exhaustion, ensuring reliable engine starting capability while minimizing unnecessary engine runs by acting only when thresholds are approached.
Solution Approach 2:
The system adjusts the voltage threshold parameters based on environmental conditions and operational history to optimize the balance between maintaining battery charge and minimizing engine start frequency. By programmable thresholds, the system adapts to different scenarios such as cold weather or high-altitude operations where battery performance varies.
