Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC tagging is used for interaction between mobile terminal and display device, then ease of operation is improved, but functionality is limited due to data storage constraints in NFC tag
Solution Approach 1:
The patent introduces a remote control device as an intermediary between the mobile terminal and display device. The remote control receives NFC tagging signals from the mobile terminal and relays connection information to enable Wi-Fi communication. This intermediary approach allows the system to overcome NFC's data storage limitations while maintaining the simplicity of NFC tagging operation.
Solution Approach 2:
The patent transitions from a single-dimension NFC tagging approach to a multi-dimensional communication architecture. After the initial NFC tagging interaction, the system establishes Wi-Fi connectivity for data transmission and uses a database for storing function settings. This dimensional expansion allows unlimited functionality while preserving the ease of NFC-based initial interaction.
2Adaptability or versatility
If data is stored in NFC tag for function settings, then adaptability is improved, but device complexity increases due to data storage requirements
Solution Approach 1:
The patent extracts the data storage function from the NFC tag and relocates it to the display device's database. The NFC tag is reduced to its core function of initiating connection, while all function settings and interlocking operations are stored in the display device's database with sufficient storage capacity, thereby reducing overall system complexity.
Solution Approach 2:
Instead of storing data directly in the NFC tag, the system copies connection information from the NFC tagging interaction to the display device's database through the remote control. This copying mechanism allows the system to leverage the NFC tag's simplicity while utilizing the database's extensive storage capabilities for comprehensive function settings.
3Adaptability or versatility
If multiple functions are implemented through NFC tagging, then adaptability is improved, but loss of information increases due to NFC tag storage limitations
Solution Approach 1:
The patent performs preliminary action by establishing Wi-Fi connectivity and transferring all necessary function settings and data to the display device's database before actual use. The NFC tag only needs to carry minimal connection initiation data, while comprehensive function information is pre-loaded into the database, preventing any information loss.
Solution Approach 2:
The remote control device serves as an intermediary that facilitates the transfer of connection information from the mobile terminal via NFC tagging to the display device. This intermediary enables the system to overcome NFC's storage limitations by routing data through a device with greater communication capabilities, thereby preserving all function-related information.
