Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex laser-scanned barcode systems are used for baggage tracking, then tracking reliability is improved, but system cost and complexity increase significantly

Engineering Contradiction:
Improvebaggage tracking reliabilityVSAvoidtracking system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the core tracking function from complex laser-scanned barcode systems and implements it using simple mobile device cameras to scan 2D barcodes. This extraction allows tracking functionality to be achieved without requiring expensive laser scanners, automated conveyor systems, or complex backend infrastructure, thereby resolving the contradiction between reliability and complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces expensive, complex laser-scanned barcode readers with inexpensive mobile devices that use standard cameras. The mobile devices are disposable consumer electronics that can be easily deployed and replaced, eliminating the need for costly dedicated tracking hardware while maintaining adequate tracking reliability

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If comprehensive baggage tracking infrastructure is deployed, then tracking coverage is improved, but operational cost increases

Engineering Contradiction:
Improvetracking coverageVSAvoidoperational cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements self-service tracking where passengers use their own mobile devices to scan barcodes and report bag locations. This eliminates the need for expensive dedicated tracking personnel and infrastructure at each location, allowing comprehensive tracking coverage without proportionally increasing operational costs

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent makes mobile devices universal tracking terminals that can function at any location with camera capability. Instead of requiring specialized tracking equipment at each airport or facility, any mobile device can serve as a tracking terminal, dramatically reducing infrastructure costs while maintaining broad tracking coverage

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

3Device complexity

If mobile device-based tracking is used, then system cost is reduced, but tracking precision may be compromised

Engineering Contradiction:
Improvetracking system costVSAvoidlocation tracking precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent introduces a centralized server as an intermediary that processes location data from multiple mobile devices and reconciles it with baggage information. This server layer compensates for the imprecision of mobile device-based location tracking by cross-referencing data sources and providing accurate baggage location information, thereby maintaining measurement precision while using low-cost mobile devices

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If traditional BIM message systems are used, then data standardization is improved, but system flexibility and ease of operation deteriorate

Engineering Contradiction:
Improvemessage system flexibilityVSAvoidintegration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces rigid, fixed-format BIM messages with dynamic JSON-based data exchange. This allows the message structure to adapt to different scenarios and requirements without requiring complex parsing or rigid integration protocols, significantly improving flexibility and ease of operation while reducing integration complexity through standardized web APIs

Inventive Principle:
Principle #15Dynamics

AI summary

An article tracking system and method are provided. The system includes an article identifier, a location identifier, a mobile application stored on a mobile device, and a cloud platform. The mobile application combines article information from the article identifier and location information from the location identifier into a data packet and transmits the data packet to the cloud platform for storage. Creating and sending a data packet for each of a plurality of locations enables to system to record the location history of the article over time.
