Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote tracking devices face inefficiencies in location determination frequency, leading to battery drain and inaccurate data transmission, as they are programmed to sample and send location data at predetermined intervals regardless of environmental conditions, which can be too frequent or infrequent depending on the device's state.
Innovation Solution
A remote tracking device equipped with a processor that monitors environmental conditions to adjust the frequency of location determinations and data transmissions, allowing for dynamic adjustment based on factors like movement speed and proximity to geographical zones, thereby optimizing battery life and data accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location determination is performed at predetermined intervals, then location data is continuously collected, but battery resources are drained constantly and location information may be too infrequent or too frequent depending on device state
Solution Approach 1:
The patent implements dynamic adjustment of location sampling frequency based on environmental conditions. The processor monitors conditions such as device movement, proximity to geographical zones, and time of day, then adjusts the sampling interval accordingly. When the device is stationary or in low-risk areas, sampling frequency is reduced to conserve battery. When movement is detected or the device approaches restricted zones, sampling frequency increases to maintain monitoring reliability.
Solution Approach 2:
The system changes the parameter of sampling frequency based on monitored environmental conditions. Instead of using a fixed predetermined interval, the sampling interval is dynamically modified according to device state and contextual factors, allowing optimization between data accuracy and energy consumption.
2Measurement precision
If location determination frequency is increased to capture fast movement, then location accuracy improves, but battery drain increases
Solution Approach 1:
The system dynamically adjusts sampling frequency based on detected movement characteristics. When the processor detects that the device is moving quickly or changing location rapidly, it increases the sampling frequency to maintain accurate tracking. When movement is minimal or the device is stationary, the sampling frequency is reduced, optimizing battery usage while maintaining measurement precision when needed.
3Productivity
If batch sending is performed at predetermined intervals, then data transmission is simplified, but location information may be too infrequent or too frequent regardless of actual conditions
Solution Approach 1:
The patent implements dynamic adjustment of batch sending intervals based on environmental conditions and data accumulation. The processor monitors conditions such as device movement, location changes, and time of day to determine optimal transmission timing. When significant location changes occur or the device approaches restricted zones, the system triggers immediate transmission rather than waiting for the predetermined batch interval, reducing response time while maintaining transmission efficiency.
4Use of energy by moving object
If GPS and cellular engines are powered down between sampling to preserve battery life, then energy consumption is reduced, but location determination frequency must be slowed
Solution Approach 1:
The system uses periodic action by power-cycling the GPS and cellular engines between sampling operations. The processor powers down these energy-intensive components between location determinations and only activates them when location sampling is required. This periodic activation significantly reduces battery consumption while maintaining necessary location tracking capabilities through optimized sampling intervals.

AI summary
A remote tracking device for use in a remote tracking system is described. The remote tracking device includes a positioning system receiver, such as GPS, operable to receive signals indicative of the location of the remote tracking device, a cellular transceiver operable to communicate with the central monitoring center, and a processor connected to the positioning system receiver and the cellular transceiver, the processor operable to monitor at least one environmental condition for the remote tracking device, and to adjust the frequency of an operation of the remote tracking devices based on the at least one environmental condition. The environmental condition may include the devices rate of movement, proximity to an area of interest, time of day, or other condition in response to which it would be desirable to alter the frequency of operation of the remote tracking device.
