Tracking Device Power Preservation via Signal Strength Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tracking devices face limitations in battery lifespan due to high power consumption, particularly when repeatedly connecting and reconnecting to mobile devices at the edge of their transmission range, leading to excessive power usage.
Innovation Solution
Implementing power preservation methods by temporarily reducing the transmission power of the tracking device when in an edge of range state, allowing it to conserve energy by limiting its effective range and reducing repeated connections with mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tracking device maintains high transmission power to ensure reliable connection with mobile devices, then the connection reliability is improved, but the battery consumption increases
Solution Approach 1:
The tracking device dynamically adjusts its transmission power based on connection status and environmental conditions. When a mobile device is detected within range, the device switches to a lower transmission power state to conserve battery, while maintaining connection reliability through intelligent power management rather than sustained high power output.
Solution Approach 2:
The system changes the transmission power parameter from a fixed high value to a variable value that adapts to operational needs. The device transitions between different power states (high power when no connection needed, low power when connected) based on real-time conditions, optimizing the balance between reliability and energy consumption.
2Area of stationary object
If the tracking device operates at full transmission power continuously, then the transmission range is maximized, but the battery lifespan is reduced
Solution Approach 1:
Instead of continuous high-power transmission, the device employs periodic scanning and intermittent transmission. The tracking device periodically checks for nearby mobile devices and only activates full transmission power when necessary, using lower power states during idle periods to extend battery lifespan while maintaining adequate transmission range when needed.
Solution Approach 2:
The device applies partial action by using reduced transmission power sufficient for typical operating conditions rather than maximum power continuously. This partial power approach extends battery life while providing adequate transmission range for normal use cases, avoiding the excessive power consumption of continuous full-power operation.
3Area of stationary object
If the tracking device repeatedly connects and reconnects to mobile devices at the edge of transmission range, then the tracking coverage is expanded, but the power consumption increases excessively
Solution Approach 1:
The tracking device uses feedback from signal strength measurements to determine when a mobile device is at the edge of transmission range. When repeated connection attempts are detected or signal strength indicates marginal connection quality, the system adjusts power levels to prevent excessive reconnection cycles, thereby reducing energy loss while maintaining tracking coverage.

AI summary
The power consumption of a tracking device can be reduced by managing the transmission power of the tracking device when a mobile device is at the edge of the range of the tracking device. A connection can be established between a tracking device and a mobile device at the edge of a first range of the tracking device. The transmission range of the tracking device can be reduced to sever the connection between the tracking device and the mobile device. After a pre-determined time interval or after a connection with the mobile device is re-established the transmission range of the tracking device can be restored.
