Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user selection is used for configuring wireless devices, then user control over communication mode is improved, but configuration time and complexity increase
Solution Approach 1:
The wireless devices automatically configure themselves by reading setting data from tags, exchanging capability information, and selecting compatible communication modes without user intervention. The device autonomously determines whether to operate in reader or card emulation mode based on the tags read and the peer device's capabilities, eliminating manual configuration steps while maintaining optimal communication setup
Solution Approach 2:
Configuration settings are pre-stored in tags and device memories before actual communication occurs. The setting data includes predefined communication mode preferences and capability information that are read in advance during the configuration phase, allowing the devices to quickly establish compatible communication parameters without real-time user input or complex negotiation
2Adaptability or versatility
If multiple communication modes are supported, then device versatility is improved, but configuration complexity increases
Solution Approach 1:
The wireless device is designed to support multiple communication modes (reader mode and card emulation mode) within a single unified architecture. The device can dynamically switch between these modes based on the situation, using a common configuration mechanism that handles both modes through the same setting data structure and capability exchange protocol, avoiding the need for separate configuration systems for each mode
Solution Approach 2:
The device changes its operational parameters (communication mode, protocol settings, capability flags) based on the setting data read from tags and the capability information exchanged with peer devices. By dynamically adjusting these parameters according to pre-stored configuration data and real-time negotiation results, the device achieves versatile communication capability without requiring complex manual configuration for each mode
3Loss of time
If automatic configuration is implemented, then configuration time is reduced, but reliability of compatible application activation may worsen
Solution Approach 1:
The configuration process includes a feedback mechanism where devices exchange capability information and confirm compatible application activation through acknowledgement data. The peer device receives capability information, determines compatible applications, and sends back confirmation data to verify successful configuration. This feedback loop ensures that automatic configuration reliably activates compatible applications by validating the configuration results against actual device capabilities
Solution Approach 2:
Compatible applications and their configuration parameters are pre-identified and stored in device memory based on the setting data read from tags. Before actual communication begins, the device pre-configures the appropriate applications and verifies their compatibility through capability exchange. This preliminary configuration ensures that when automatic configuration is completed, the correct compatible applications are already prepared and activated, maintaining high reliability
