Solution Overview

Problem

Existing tracking devices face challenges in detecting when they have been removed from vehicles or individuals without relying on GPS or wireless communication network information, which consumes significant power and resources.

Innovation Solution

The tracking device incorporates orientation sensors, such as accelerometers and gyroscopes, to determine orientation changes by comparing baseline and current orientation values, sending alerts based on predefined criteria, thereby eliminating the need for GPS or wireless communication network data to detect removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If GPS or wireless communication network information is used to detect tracking device removal, then detection reliability is improved, but power consumption and resource usage increase

Engineering Contradiction:

Improvedetection reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces GPS and wireless communication network-based detection mechanisms with an orientation sensor-based detection mechanism. The orientation sensor monitors changes in the device's physical orientation relative to the vehicle, substituting mechanical/physical sensing for resource-intensive electronic communication and positioning systems, thereby reducing power consumption while maintaining detection capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the essential detection function from the GPS and network communication systems, isolating only the orientation monitoring aspect. By separating this specific function (detecting removal through orientation change) from the full GPS/network system, the patent achieves detection reliability without the associated high power consumption of continuous positioning and communication

Inventive Principle:

Principle #2Taking out (Extraction)

2Measurement precision

If continuous GPS or network communication is used to monitor tracking device status, then detection accuracy is improved, but resource consumption increases

Engineering Contradiction:

Improvedetection accuracyVSAvoidresource consumption

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

The patent implements periodic orientation monitoring instead of continuous GPS or network communication. The orientation sensor takes measurements at specific intervals, comparing current orientation against baseline orientation data. This periodic sampling maintains detection accuracy for removal events while significantly reducing resource consumption compared to continuous monitoring systems

Inventive Principle:

Principle #19Periodic action

3Use of energy by moving object

If orientation sensors are used to detect tracking device removal, then power consumption is reduced, but detection reliability may be compromised

Engineering Contradiction:

Improvepower consumptionVSAvoiddetection reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where orientation sensor data is continuously compared against baseline orientation values. When the orientation change exceeds a predetermined threshold, the system generates an alert. This feedback loop ensures reliable detection of removal events while maintaining low power consumption, as the system only activates full alert protocols when necessary rather than continuously

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes the detection parameter from GPS coordinates or network signal presence to orientation angle measurements. By monitoring changes in orientation parameters (pitch, roll, yaw angles) rather than positional parameters, the system achieves reliable removal detection with lower power consumption, as orientation sensors require minimal energy compared to GPS receivers or wireless communication modules

Inventive Principle:

Principle #35Parameter changes

AI summary

A battery-powered tracking device may comprise a processor and orientation sensors that generate orientation signals and provide them to a processor. The processor may use the orientation signals, or orientation values corresponding thereto, to determine whether or not the tracking device has moved during a configured no-change period relative to a baseline orientation that was determined before the no-change period. The no-change period may be selected to correspond to an amount of time during which the tracking device, or an item with which it is associated, such as a vehicle, tool, or shipping package, is not expected to move. If a determination is made during the no-change period that the tracking device has changed orientation, an alert may be sent to a tracking application to notify a user of the application that the tracking device may have been removed from the item with which is it associated.
