Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If USB cable connection is used to establish communication between mobile device and fixed device, then connection reliability is ensured, but area limitation and operational convenience deteriorate
Solution Approach 1:
The patent applies preliminary action by performing USB cable connection and driver installation only once during initial binding. The connection information (device ID, IP address, port number) is stored in advance, enabling subsequent wireless connections without repeated USB cable usage or driver installation, thus resolving the contradiction between connection reliability and operational convenience.
Solution Approach 2:
The patent replaces the mechanical USB cable connection system with a wireless network communication system for subsequent connections. The mechanical cable connection is substituted by wireless data transmission using stored connection information, eliminating the need for physical cable manipulation while maintaining connection reliability through pre-established communication parameters.
2Stability of the object's composition
If USB cable connection is used to establish communication between mobile device and fixed device, then connection stability is maintained, but area of usage is limited
Solution Approach 1:
The patent substitutes the mechanical USB cable system with wireless network communication, replacing the physical constraint of cable length with the flexibility of wireless transmission. This allows the mobile device to communicate with the fixed device beyond the limited area imposed by cable length, while connection stability is maintained through stored communication parameters.
Solution Approach 2:
The patent transitions from one-dimensional spatial constraint (cable length limiting movement in straight line) to three-dimensional wireless communication freedom. The mobile device can move freely in three-dimensional space within wireless coverage area, no longer constrained by cable length, thus expanding the usable area while maintaining connection stability.
3Reliability
If USB cable connection is required for each communication connection, then connection security is ensured, but productivity deteriorates
Solution Approach 1:
The patent performs security verification and driver installation in advance during the binding phase via USB cable connection. Subsequent connections use the pre-verified connection information for rapid reconnection, eliminating repeated security checks and driver installations, thus improving productivity while maintaining connection security through pre-established trusted connections.
Solution Approach 2:
The system implements self-service by automatically using stored connection information (device ID, IP address, port number) for subsequent connections without requiring manual intervention for driver installation or connection configuration. This automated reconnection process improves productivity while maintaining security through the previously verified binding relationship.

AI summary
Embodiments of the present application provide a method and an apparatus for establishing a communication connection between a mobile device and a fixed device. The mobile device receives a broadcast message containing first connection information related to a fixed device sent by the fixed device via the wireless network; determines whether the first connection information in the received broadcast message matches connection information of a fixed device that has been bound to the mobile device, wherein the connection information of the fixed device that has been bound to the mobile device is received from the fixed device by the mobile device via a Universal Serial Bus (USB) connection when the mobile device is connected to the fixed device via the USB connection; if so, returns a second connection information of the mobile device to the matching fixed device via the wireless network, such that the fixed device sends a connection request to the mobile device according to the second connection information; and receives the connection request to establish a communication connection between the mobile device and the fixed device. The present solution solves the problems that a USB cable is required for each communication connection and that mobile devices are subjected to area limitations.
