Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If location data is received from multiple disparate positioning technologies, then the adaptability and versatility of the location-based service platform is improved, but the device complexity increases due to integrating multiple technology interfaces

Engineering Contradiction:
ImproveadaptabilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a standardized interface layer that acts as an intermediary between multiple disparate positioning technologies and the core location-based service platform. This interface layer receives location data from various sources (GPS, RFID, wireless technologies) and standardizes it into a common format, allowing the platform to access multiple technology sources without direct complex integration with each technology, thus improving adaptability while managing complexity through abstraction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If location data from multiple sources is selectively processed based on rules, then the measurement precision and reliability of location data is improved, but the loss of time increases due to processing and evaluating multiple data sources

Engineering Contradiction:
ImproveprecisionVSAvoidtime
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements pre-established selection rules and criteria for evaluating location data from multiple sources. These rules are configured in advance to automatically assess data quality, accuracy, and reliability metrics. When location data is received, the pre-configured rules immediately evaluate and select the most reliable data source without requiring real-time complex analysis, thus improving measurement precision while minimizing time loss through preliminary rule configuration.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If location data is standardized and formatted according to specific protocols, then the ease of operation and interoperability is improved, but the device complexity increases due to data processing requirements

Engineering Contradiction:
Improveease of operationVSAvoidcomplexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a universal standardized interface that can handle multiple data formats and protocols from different positioning technologies. This universal interface layer provides multi-functional capabilities to convert, format, and standardize various location data types into a common structure that applications can easily consume. By creating a single universal interface that handles multiple formats, the system improves ease of operation and interoperability while managing complexity through consolidation rather than multiple specialized processing paths.

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

AI summary

System and methods are provided that facilitate integrated and seamless utilization of location data generated by multiple disparate positioning technologies adequate for outdoor or indoor positioning. Location data from multiple sources is selectively processed based on rules that account for availability, accuracy, cost, reliability of location data. At least one of the multiple sources is based on radio frequency identification (RFID) technology. Rules can be operator specific or can be automatically generated based on historic location data or cost-benefit analysis. Processing of selected data includes formatting data according to a specific standard or protocol, or augmenting the data with metadata. Standardized data is conveyed through a communication link for utilization in various applications such as vendor applications for navigation or web-based services, as well as custom and development applications.
