Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual activation and pairing of NFC modules is implemented, then user control over communication modules is maintained, but user effort and time consumption increase
Solution Approach 1:
The terminal automatically activates the second NFC module and performs pairing with external devices without requiring manual user intervention. The system self-determines when activation is needed based on detected external devices or payment conditions, and automatically completes the pairing process, thereby eliminating the time loss associated with manual operations.
Solution Approach 2:
The terminal pre-configures the second NFC module for automatic activation based on predetermined conditions such as detecting specific external devices or entering payment modes. This preliminary setup allows the system to automatically initiate pairing and activation processes without requiring real-time manual user input, thus reducing operational time.
2Productivity
If the second NFC module is continuously activated, then pairing and data transmission can occur immediately, but battery consumption increases
Solution Approach 1:
The terminal dynamically controls the activation state of the second NFC module based on real-time conditions. The module remains deactivated during normal operation to conserve battery, and is automatically activated only when specific conditions are met (such as detecting an external device or entering a payment mode), thus achieving both energy efficiency and rapid response when needed.
Solution Approach 2:
The terminal periodically checks for conditions that would trigger activation of the second NFC module, such as proximity of external devices or specific application states. This periodic monitoring allows the system to maintain low power consumption while being ready to activate quickly when conditions warrant, balancing battery usage with operational readiness.
3Device complexity
If the first NFC module is used for all communication tasks, then device complexity is reduced, but communication performance and versatility are limited
Solution Approach 1:
The terminal employs two different NFC modules with distinct characteristics: the first module optimized for low-power operations and the second module optimized for high-performance pairing and data transmission. By having both modules available, the system achieves multi-functionality, selecting the appropriate module based on the specific communication task requirements, thus enhancing versatility without excessive complexity.
Solution Approach 2:
Each NFC module is designed with specific local qualities optimized for particular functions. The first module has characteristics suited for energy-efficient advertising and initial contact, while the second module has characteristics optimized for rapid pairing and high-speed data transmission. This division of functional qualities allows the system to handle different communication scenarios with appropriately optimized hardware.
4Ease of operation
If automatic pairing is implemented, then user convenience is improved, but security control and user awareness are reduced
Solution Approach 1:
The terminal provides feedback to the user about the automatic pairing process, including notifications when external devices are detected, when pairing is initiated, and when pairing is completed. This feedback mechanism maintains user awareness and security control by keeping the user informed about automatic operations, allowing them to monitor and intervene if necessary.
