Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If telematic monitoring device relies on vehicle power, then device complexity is reduced, but reliability deteriorates when vehicle power is lost or connection is unstable
Solution Approach 1:
The patent combines the vehicle power system and independent battery power system into a unified power architecture. The telematic monitoring device can draw power from either the vehicle electrical system or the integrated battery device, creating a merged power supply that maintains continuous operation regardless of vehicle power availability.
Solution Approach 2:
The battery device performs preliminary charging actions by accumulating energy in advance when vehicle power is available. The control circuitry monitors vehicle power status and proactively charges the battery during normal operation, ensuring power readiness before vehicle power is lost or disconnected.
2Reliability
If battery provides full power continuously, then operation continuity is improved, but energy consumption increases
Solution Approach 1:
The power provision system dynamically adjusts between full power mode and low power mode based on real-time operational conditions. The control circuitry monitors vehicle status, connection stability, and battery charge level to determine appropriate power delivery levels, transitioning from high-power continuous operation to energy-efficient standby mode when full power is not required.
Solution Approach 2:
The system changes the power output parameter of the battery based on operational needs. When vehicle power is stable and connection is reliable, the battery operates in low-power standby mode. When vehicle power is lost or connection becomes unstable, the battery transitions to full power output mode to maintain continuous operation, effectively modulating the power parameter to balance reliability and energy consumption.
3Quantity of substance
If battery charges continuously when vehicle is on, then energy availability is improved, but power loss to vehicle increases
Solution Approach 1:
The control circuitry implements feedback control by continuously monitoring vehicle power status, battery charge level, and operational requirements. Based on this feedback, the system intelligently determines the optimal charge current, reducing charging rate when battery is nearly full or vehicle power demand is high, and increasing charging rate when battery needs energy and vehicle power is abundant, thereby balancing energy storage with minimal power loss.
