Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal strength analysis is used to determine device proximity, then device matching accuracy is improved, but system complexity increases
Solution Approach 1:
The system segments the device matching process into multiple independent components: signal strength analysis module, RFID tag detection module, and tie-breaking scheme module. Each component handles a specific aspect of proximity determination, allowing the system to achieve high accuracy through coordinated simple modules rather than one complex algorithm.
Solution Approach 2:
The patent introduces an intermediary matching system that mediates between mobile gaming devices and POS terminals. This intermediary layer processes signal strength data, RFID information, and applies tie-breaking schemes to resolve ambiguities, simplifying the overall system architecture while maintaining high matching precision.
2Reliability
If multiple detection methods (signal strength, RFID) are combined for device matching, then matching reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple independent detection methods (signal strength analysis and RFID tag detection) into a unified device matching system. By combining these methods, the system achieves higher reliability through cross-validation, where each method compensates for the weaknesses of the other, while the modular integration keeps individual component complexity manageable.
Solution Approach 2:
The system changes detection parameters dynamically by switching between different detection methods based on conditions. For example, it may prioritize signal strength analysis in open environments and RFID detection in crowded areas, adjusting the weight and threshold parameters of each method to maintain reliability while managing complexity.
3Measurement precision
If tie-breaking schemes are implemented to select POS terminals, then transaction accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing priority rules and criteria for tie-breaking before actual device matching occurs. These pre-defined schemes (such as employee presence priority, player history priority) are prepared in advance, allowing the system to quickly resolve ties during transactions without complex real-time calculations, thus improving accuracy while minimizing processing time.
4Productivity
If device proximity detection is enhanced with multiple criteria, then communication efficiency is improved, but ease of operation decreases
Solution Approach 1:
The system implements self-service by automatically performing device matching and POS terminal selection based on the established criteria (signal strength, RFID data, tie-breaking schemes). The process occurs without user intervention, with the system autonomously determining optimal connections and managing communication channels, thereby improving efficiency while maintaining ease of operation through automation.
