Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used for analyte data communication, then ease of operation is improved, but reliability of transmission may deteriorate
Solution Approach 1:
The patent combines both NFC antenna and Bluetooth antenna in a single sensor control device, allowing the system to use multiple wireless transmission modes. This merging of communication technologies ensures that if one wireless transmission method fails or is unavailable, the other can serve as a backup, thereby maintaining reliable data transmission while preserving the ease of operation benefits of wireless communication.
2Device complexity
If antenna is placed directly on circuit board, then device complexity is reduced, but reliability of wireless transmission deteriorates
Solution Approach 1:
The patent introduces an antenna support structure as an intermediary component between the circuit board and the antenna elements. This support structure provides mechanical stability and proper positioning for the NFC and Bluetooth antennas, improving wireless transmission reliability without significantly increasing device complexity, as the support structure can be integrated into the existing device architecture.
