Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If GPS is used to locate electronic devices, then location accuracy is improved, but GPS cannot be used for non-electronic items or devices without GPS functionality

Engineering Contradiction:
Improvelocation accuracyVSAvoidapplicability to non-electronic items
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

An electronic device with GPS functionality serves as an intermediary between non-electronic items and the localization system. The tag attached to non-electronic items communicates with the electronic device, which then uses its GPS capability to determine and report the location, thereby enabling indirect GPS-based localization of items without electronic components.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct GPS hardware in all items with a wireless communication-based system. Instead of embedding GPS receivers in every item (mechanical/electronic approach), the system uses wireless tags and electronic device intermediaries to achieve localization through software and communication protocols.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional GPS systems are used, then location tracking is achieved, but the systems are ineffective for personal property without electronic components

Engineering Contradiction:
Improvetracking effectivenessVSAvoidcompatibility with non-electronic property
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The localization system achieves universality by designing a multi-functional architecture that can track both electronic devices with GPS and non-electronic items without GPS. The system adapts its operation mode based on the target object type, using direct GPS for electronic devices and wireless tag intermediaries for non-electronic items, thereby providing reliable tracking across diverse object types.

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

3Ease of operation

If wireless signals are transmitted for localization, then location determination is enabled, but secure tracking requires encryption protocols

Engineering Contradiction:
Improvelocalization capabilityVSAvoidencryption implementation
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system implements self-service security by automatically establishing encrypted communication channels between tags and electronic devices without requiring manual configuration. The encryption protocols are integrated into the wireless communication stack, enabling secure tracking to occur automatically as part of the localization process.

Inventive Principle:
Principle #25Self-service
