Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Short-range wireless communication between smart wearable devices and communication devices is limited by distance and obstacles, leading to ineffective interaction.
Innovation Solution
A method and apparatus that enable wireless communication between communication terminals using a server, allowing for long-range communication by determining whether to use a server-based mode, transmitting connection requests, and authenticating devices, thereby establishing communication even when short-range communication is not possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If short-range wireless communication is used between wearable devices and communication devices, then power consumption is low and connection is direct, but communication range is limited and obstacles block the connection
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates communication between the wearable device and communication device when direct short-range communication is not feasible. The server receives data from the wearable device, determines whether the target communication device is online, and forwards data accordingly, enabling long-range communication while maintaining the low-power short-range communication mode for direct connections.
2Ease of operation
If short-range wireless communication is used, then connection establishment is simple and direct, but communication cannot be performed when devices are far apart or obstacles are present
Solution Approach 1:
The server acts as a reliable intermediary that maintains communication reliability by receiving data from the wearable device, determining the online status of the target communication device, and forwarding data through appropriate channels. This ensures communication can proceed even when direct short-range connection is not possible due to distance or obstacles.
Solution Approach 2:
The system performs preliminary actions by storing communication device information and online status in the server in advance. When the wearable device needs to communicate, the server already has the necessary routing information ready, enabling seamless communication without requiring complex real-time discovery or connection establishment procedures.
3Reliability
If long-range communication via server is implemented, then communication range and reliability are improved, but system complexity and authentication requirements increase
Solution Approach 1:
Authentication information and device relationships are established in advance through preliminary pairing and binding operations. The server stores authentication credentials and device association information beforehand, so that when communication is needed, the authentication process is streamlined and does not add significant complexity to the actual communication flow.
