Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing methods are used to determine when a tracking device has been left behind, then the system can provide basic tracking functionality, but the detection accuracy and reliability are insufficient

Engineering Contradiction:
Improvetracking device detection accuracyVSAvoidfalse alert rate
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent segments the detection process into multiple independent evaluation capabilities (communication protocol detection, location determination, motion analysis) that operate separately and contribute to the overall confidence score. Each capability evaluates specific aspects of tracking device status independently, allowing the system to aggregate evidence from multiple sources rather than relying on a single detection method.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements continuous feedback loops where detection results from multiple evaluation capabilities are constantly monitored and fed back into the confidence calculation. The confidence delay timer and last resort timer provide temporal feedback mechanisms that adjust alert generation based on the persistence and consistency of detection signals across multiple time intervals.

Inventive Principle:
Principle #23Feedback

2Reliability

If multiple evaluation capabilities are used to improve detection accuracy, then the reliability of out-of-range detection improves, but the device complexity and processing requirements increase

Engineering Contradiction:
Improveout-of-range detection reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The user device is designed with multiple communication components that can serve dual purposes: primary communication for normal operation and secondary communication for tracking device detection. The same processing module that handles general device operations also manages the out-of-range evaluation process, combining multiple functions into unified hardware and software components to reduce overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs preliminary evaluations using available capabilities before triggering full alert sequences. Confidence delay timers and last resort timers are pre-configured with threshold values, allowing the system to quickly assess whether detection conditions warrant further investigation or immediate alert generation, reducing processing overhead for routine situations.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If continuous monitoring is implemented to ensure accurate tracking device detection, then detection precision improves, but energy consumption increases

Engineering Contradiction:
Improvetracking device decoupling detection precisionVSAvoiduser device energy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system implements periodic monitoring intervals rather than continuous monitoring, with evaluation capabilities activated at scheduled times to check tracking device status. The confidence delay timer and last resort timer create periodic evaluation cycles that balance detection accuracy with energy conservation, allowing the device to enter low-power states between evaluation intervals while maintaining effective surveillance.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts monitoring parameters based on confidence levels and detection history. When confidence is high that a tracking device is properly coupled, monitoring intensity is reduced. When confidence decreases or decoupling events are detected, the system increases evaluation frequency and activates additional capabilities, optimizing energy usage based on actual detection needs rather than maintaining constant high-level monitoring.

Inventive Principle:
Principle #35Parameter changes
