Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reporting frequency is increased to track vehicle location in real-time, then location tracking accuracy is improved, but battery consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of reporting frequency based on vehicle movement state. When the vehicle is stationary, reporting frequency is reduced to conserve battery. When the vehicle is in motion, reporting frequency increases to maintain tracking accuracy. This dynamic adaptation resolves the contradiction between continuous tracking and battery conservation.
Solution Approach 2:
The system changes the reporting frequency parameter based on operational conditions. By monitoring vehicle movement and environmental factors, the system adjusts the reporting interval parameter to optimize the balance between location accuracy and energy consumption throughout the device's operational lifetime.
2Duration of action of moving object
If connection interval is extended to save battery in extreme weather, then battery life is improved, but real-time monitoring capability deteriorates
Solution Approach 1:
The connection interval is dynamically adjusted based on temperature conditions and battery charge levels. In extreme cold or heat, the system extends intervals to preserve battery life while maintaining sufficient monitoring capability. The system adapts connection frequency to environmental conditions rather than using a fixed interval.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor battery charge levels, temperature conditions, and vehicle movement state. This feedback informs dynamic adjustments to connection intervals, ensuring real-time monitoring capability is maintained when needed while extending battery life during stable conditions through longer intervals.
3Measurement precision
If reporting frequency is increased during repossession events, then location tracking precision is improved, but battery charge depletes faster
Solution Approach 1:
The system dynamically increases reporting frequency during active repossession events when precise location tracking is critical, then reduces frequency during stable periods. This temporal differentiation allows high-precision tracking when needed while conserving battery charge during routine monitoring phases.
Solution Approach 2:
The patent implements periodic reporting with variable intervals. During repossession events, reporting occurs at high frequency. During stable periods with no events, reporting frequency decreases. This periodic variation in reporting intensity maintains tracking precision during critical events while conserving battery charge during routine operation.

AI summary
A method and system for battery management for a mobile geofence apparatus. Location information for a vehicle, temperature information for the vehicle and battery information for the internal battery on the mobile geofence apparatus is automatically, continuously and periodically collected and sent during a connection interval in real-time to an external network server network device via a communications network for tracking the vehicle in real-time. The battery information is displayed on the mobile geofence apparatus for a viewer and is also sent to an external server network device for display to a viewer. Internal battery usage is automatically managed internally on the mobile geofence apparatus using the collected location, battery and temperature information. The internal battery on the mobile geofence apparatus is also automatically managed externally via the external server network device using the collected location, battery and temperature information.
