Existing communication devices face challenges in seamlessly switching between Near Field Communication (NFC) and Bluetooth for data transmission based on data size, and in coordinating wireless communication across unreliable links, especially in intermittent signal conditions.
Innovation Solution
A communication system that includes a Multi-Function Peripheral (MFP) capable of performing NFC, Wi-Fi Direct (WFD), and normal Wi-Fi communication, allowing it to dynamically switch between these modes and manage network settings to ensure efficient data transfer, even in environments with poor signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If NFC is used for data transmission, then short-distance communication is achieved, but transmission speed is insufficient for large data
Solution Approach 1:
The communication device dynamically switches between NFC and Bluetooth communication modes based on real-time detection of data size and transmission conditions. When data size exceeds a threshold, the system automatically transitions from NFC to Bluetooth to maintain high transmission speed, and can switch back to NFC when data size is small, optimizing performance across varying conditions
Solution Approach 2:
The system changes the communication parameter (mode selection) based on the data size parameter. By monitoring the size of data to be transmitted and comparing it against a predetermined threshold, the device adjusts its communication mode accordingly - using NFC for small data and Bluetooth for large data, thereby resolving the contradiction between transmission speed and device complexity
2Productivity
If Bluetooth is used for data transmission, then transmission speed is improved, but connection establishment complexity increases
Solution Approach 1:
The system performs preliminary detection of data size before initiating communication. By pre-judging whether the data size exceeds the threshold, the device can proactively select the appropriate communication mode (NFC for small data, Bluetooth for large data), avoiding the need for complex real-time handover decisions during data transmission and simplifying the connection establishment process
Solution Approach 2:
The communication device autonomously determines the optimal communication mode by monitoring its own data size and comparing it against the predetermined threshold. This self-service approach eliminates the need for external control or complex manual configuration, allowing the system to automatically select between NFC and Bluetooth based on intrinsic conditions, thereby improving productivity while managing device complexity
3Adaptability or versatility
If multiple wireless networks are supported, then communication versatility is improved, but network selection complexity increases
Solution Approach 1:
The communication device integrates support for multiple wireless networks (NFC, Bluetooth, and other wireless networks) to provide universal communication capability. By incorporating this multi-functionality, the system can adapt to various communication scenarios and network environments, improving versatility while managing the complexity of network settings through a unified selection mechanism based on data size and conditions
