Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If contactless transaction systems using NFC are implemented, then transaction speed and convenience are improved, but user comfort and familiarity deteriorate due to user discomfort or unfamiliarity with the technology
Solution Approach 1:
The system provides feedback to users through visual indicators (LED lights) and haptic feedback (vibrations) during contactless transactions. The LED ring around the NFC antenna changes colors to indicate transaction status, and the device vibrates to confirm successful transactions, making the invisible NFC process visible and tangible for users.
Solution Approach 2:
The patent introduces an intermediary layer of visual and haptic feedback between the user and the NFC transaction process. This intermediary feedback mechanism bridges the gap between the user's lack of familiarity with contactless technology and the need for quick transactions, making the process more intuitive and comfortable.
2Productivity
If contactless transaction systems are deployed, then transaction processing efficiency is improved, but system reliability deteriorates due to errors and anomalies in transaction processing
Solution Approach 1:
The system performs preliminary actions by detecting and logging transaction attempts before they are fully processed. It pre-identifies potential errors and anomalies by analyzing transaction data patterns, allowing the system to prepare remedial actions in advance and prevent processing failures before they occur.
Solution Approach 2:
The system implements continuous feedback loops that monitor transaction processing in real-time. When errors or anomalies are detected, the system provides feedback to adjust processing parameters or trigger remedial actions, ensuring high reliability while maintaining efficient transaction processing.
3Reliability
If data collection and analysis routines are implemented to detect errors, then transaction reliability is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The system performs self-service by automatically detecting, analyzing, and remedying its own errors and anomalies without external intervention. The embedded processing routines continuously monitor transaction data, identify issues, and execute corrective actions autonomously, improving reliability while keeping the system architecture relatively simple.
Solution Approach 2:
The system changes processing parameters dynamically based on detected transaction patterns and error types. By adjusting analysis depth, data collection frequency, and remedial action thresholds based on real-time conditions, the system maintains high reliability while adapting processing complexity to actual needs rather than operating at maximum complexity continuously.
