Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the communication circuit is activated and deactivated periodically to reduce power consumption, then power consumption is reduced, but the ability to respond to location measurement needs and battery status changes is compromised
Solution Approach 1:
The patent implements dynamic operation cycle adjustment where the communication circuit's activation/deactivation timing is not fixed but adapts based on real-time device state. The processor modifies the operation cycle parameters (such as DRX cycle length, TAU timer values) according to location measurement needs and battery status, allowing the system to transition between power-saving mode and responsive mode as required by current conditions.
Solution Approach 2:
The system establishes a feedback mechanism where the processor continuously monitors device state (location measurement requirements, battery remaining power) and uses this information to adjust the communication circuit's operation cycle. The network also provides feedback through response messages that contain updated operation cycle parameters, creating a closed-loop control system that adapts to changing conditions.
2Use of energy by moving object
If the operation cycle is extended to save power, then power consumption is reduced, but location measurement frequency and response time are degraded
Solution Approach 1:
The operation cycle duration is made dynamic rather than static. When the device needs frequent location measurements or has low battery power, the processor adjusts the operation cycle parameters (shortening the cycle or adjusting DRX timing) to reduce response time while still maintaining power savings compared to continuous operation. This dynamic adjustment resolves the contradiction between power saving and response time.
3Productivity
If the communication circuit operates continuously to ensure quick response, then response time is improved, but power consumption increases
Solution Approach 1:
Instead of continuous operation, the system uses optimized periodic action with adaptive timing. The communication circuit operates periodically with adjusted intervals based on device state, achieving sufficient response capability for location measurements while minimizing power consumption. The periodic action is tuned dynamically to balance responsiveness and energy efficiency.
Solution Approach 2:
The system dynamically adjusts the periodic operation parameters to match actual needs. When quick response is critical, the cycle shortens; when power saving is prioritized, the cycle extends. This dynamic adaptation allows the system to achieve adequate productivity without the excessive power consumption of continuous operation.
