Communication Device Pairing via Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in identifying and connecting to specific external devices due to similar names and the time-consuming process of pairing, especially when multiple devices with similar names are present, and there is a need to avoid disturbing devices in use by others.
Innovation Solution
A communication device and method that transmit a discovery message to search for external devices, receive response messages indicating device identification functions, display a user interface to select devices with identification functions, and perform operations like LED blinking, sound output, or vibration to confirm selection before pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a discovery message is transmitted to search for external devices, then the communication device can find available devices, but it becomes difficult to identify the specific device to connect when multiple devices with similar names are present
Solution Approach 1:
The patent applies visual feedback through LED indicators and display screen changes to help users identify the selected external device. The communication device provides real-time visual feedback showing which external device is currently selected, making it easy to distinguish between multiple devices with similar names through observable state changes rather than relying solely on device names.
2Reliability
If the communication device performs pairing with external devices, then connection is established, but the pairing process becomes time-consuming when multiple devices need to be identified and selected
Solution Approach 1:
The patent implements a feedback mechanism where the communication device provides real-time visual feedback (LED indicators, display updates) to show users which external device is currently selected and the status of the pairing process. This feedback allows users to quickly verify device selection and monitor pairing progress, reducing the time needed to complete connections by eliminating uncertainty and the need for repeated trial-and-error pairing attempts.
Solution Approach 2:
The patent performs preliminary device identification and selection confirmation through visual feedback before initiating the pairing process. By allowing users to verify the selected device through LED indicators and display information beforehand, the system ensures correct device selection in advance, preventing time-wasting re-pairing operations and streamlining the overall connection process.
3Productivity
If the communication device connects to external devices without identification functions, then connection can be made, but it may disturb devices that are in use by others
Solution Approach 1:
The patent performs preliminary verification by checking whether external devices provide identification functions (such as LED indicators or display capabilities) before initiating pairing. This preliminary action allows the communication device to identify suitable devices that can confirm their selection status, avoiding connections to devices that are in use by others and would not provide proper identification feedback.
Solution Approach 2:
The patent requires external devices to provide identification feedback (through LEDs, displays, or other indicators) to confirm they are the intended target for connection. This feedback mechanism ensures that users can verify the correct device is being connected, preventing accidental connections to devices in use by others and reducing harmful disturbances.

AI summary
A communication device and a communication method are provided. The communication device is configured to search for an external device that may be connected to the communication device before the communication device is connected to the external device and transmits and receives data.
