Solution Overview
Problem
Wearable devices face challenges in network access due to limited battery life and single antenna constraints, and existing solutions lack authentication mechanisms for authorized access when using a terminal as a relay.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wearable device uses a terminal as a relay to access the network, then network access capability is improved, but security control and authentication become complex
Solution Approach 1:
The patent introduces a management entity as an intermediary between the terminal and the wearable device. This management entity maintains a whitelist of authorized wearable devices and handles authentication requests, thereby simplifying the authentication process for the terminal while ensuring security. The management entity acts as a mediator that offloads the authentication complexity from the terminal to a dedicated server-side component.
Solution Approach 2:
The patent implements preliminary action by pre-establishing a trust relationship and whitelist of authorized wearable devices in the management entity before actual network access occurs. The terminal and wearable device undergo preliminary authentication and pairing processes, so that when network access is requested, the management entity can quickly verify authorization against the pre-configured whitelist, reducing real-time authentication complexity.
2Ease of operation
If the terminal allows all wearable devices to access the network, then ease of operation is improved, but security and authorization control deteriorate
Solution Approach 1:
The management entity serves as an intermediary that handles the complex authorization control logic, allowing the terminal to maintain a simple user interface. The terminal can present simple options to the user (allow all or allow specific devices), while the management entity enforces the actual authorization policies by checking the whitelist, thus maintaining both ease of operation and security.
Solution Approach 2:
The system implements feedback mechanisms where the management entity provides authorization decisions back to the terminal. When a wearable device attempts to access the network, the management entity checks the whitelist and provides feedback on whether access should be granted, enabling the terminal to enforce security policies without having to implement complex authentication logic locally.
3Volume of moving object
If the wearable device has a small battery, then device portability is improved, but standby time deteriorates
Solution Approach 1:
The wearable device leverages the computational resources and network connectivity of the paired terminal (smartphone) to perform tasks that would otherwise require the wearable's own battery power. The terminal handles heavy processing, network protocol management, and data buffering, allowing the wearable to maintain minimal local functionality while extending its effective operational duration.
Solution Approach 2:
The patent merges the functionality of the wearable device with the terminal by establishing a relay connection where the terminal extends the wearable's capabilities. The terminal and wearable work as a combined system, with the terminal providing power-intensive functions and the wearable providing user proximity and basic sensing, thereby extending the overall system's operational duration beyond what the small wearable battery could achieve alone.
4Device complexity
If the wearable device uses a single antenna, then device simplicity is improved, but data transmission speed deteriorates
Solution Approach 1:
The terminal acts as an intermediary that compensates for the wearable's single-antenna limitation. The terminal, which possesses multiple antennas and advanced MIMO capabilities, handles the high-speed data transmission tasks, while the wearable's single antenna is used only for basic proximity communication and relay connection establishment, effectively bypassing the speed limitation.
Solution Approach 2:
The patent shifts the data transmission dimension from the wearable device to the terminal. Instead of attempting to achieve high-speed transmission through the wearable's limited single antenna, the system uses the terminal's multi-antenna infrastructure for high-speed data paths, while the wearable operates in a different dimensional space with simpler communication requirements.
