Stylus Pairing via Keyboard Coil to Avoid Wrong-Device Prompts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pairing methods for electronic devices and styluses often result in multiple devices displaying pairing dialog boxes when multiple Bluetooth-enabled devices are present, causing user disturbance.
Innovation Solution
A pairing method and system that utilizes a wireless keyboard with a coil to charge a stylus and act as an intermediate apparatus for pairing, allowing the stylus to directionally transmit a pairing request to the intended electronic device, preventing other devices from displaying dialog boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stylus broadcasts a pairing packet through Bluetooth scanning, then any Bluetooth-enabled electronic device can receive the packet and display a pairing dialog box, but this causes disturbance to users when multiple devices are present
Solution Approach 1:
The wireless keyboard acts as an intermediary device between the stylus and the electronic device. The stylus first establishes a connection with the wireless keyboard, which then forwards the pairing request to the target electronic device. This intermediary approach allows the pairing process to be initiated through a specific device (the keyboard) rather than being broadcast to all Bluetooth devices in range, thereby preventing unwanted pairing dialog boxes on other devices while maintaining pairing compatibility.
2Ease of operation
If the stylus connects directly to the electronic device via Bluetooth, then the pairing process is simple and direct, but other electronic devices around the stylus also display pairing dialog boxes
Solution Approach 1:
The wireless keyboard performs preliminary actions by establishing a connection with the stylus first and preparing to forward the pairing request. This preliminary connection setup allows the system to control the pairing initiation process, ensuring that only the intended electronic device receives the pairing request through the keyboard's directed communication, rather than allowing random Bluetooth devices to intercept it.
3Adaptability or versatility
If multiple electronic devices are present around the stylus, then the stylus can potentially pair with any of them, but this creates confusion and requires user intervention to select the correct device
Solution Approach 1:
The wireless keyboard serves as a mediator that simplifies the pairing process by being the designated entry point for the stylus. Instead of the stylus needing to discover and select from multiple Bluetooth devices, the user simply needs to place the stylus on the keyboard, which automatically initiates the pairing process with the connected electronic device. This reduces the perceived complexity for the user while maintaining the ability to pair with compatible devices.

AI summary
Embodiments of this application provide a pairing method and a pairing system. The pairing system includes a stylus, a wireless keyboard, and an electronic device. The stylus includes a first coil, and the wireless keyboard includes a second coil. The method includes: In response to that the wireless keyboard charges the stylus through the second coil and the first coil, the stylus sends a pairing request to the wireless keyboard through the first coil and the second coil. The wireless keyboard sends the pairing request to the electronic device. The electronic device displays a pairing dialog box based on the pairing request, where the pairing dialog box is used to prompt a user to trigger the electronic device and the stylus to perform pairing. In the embodiments of this application, the stylus uses the wireless keyboard as an intermediate apparatus for pairing the electronic device with the stylus, and the wireless keyboard can directionally transmit the pairing request from the stylus to the electronic device, so that the electronic device displays the dialog box while other electronic devices around the stylus are prevented from displaying a dialog box, thereby improving user experience.
