Bluetooth Pairing Notification for Printer Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless control systems for printing apparatuses require users to physically interact with the devices for pairing, making the process cumbersome and burdensome, especially when multiple devices are nearby.
Innovation Solution
A control system utilizing Bluetooth communication, where a terminal device performs first Bluetooth communication without a pairing connection to transmit a notification instruction command to a printing apparatus, allowing the apparatus to perform a notification operation, such as sounding a buzzer, to identify the selected device before establishing a pairing connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pairing connection is established before communication, then communication reliability is improved, but operation complexity increases and user convenience deteriorates
Solution Approach 1:
The system performs preliminary identification and selection of the printing apparatus through first Bluetooth communication before establishing the pairing connection. The terminal device can identify and select the target printing apparatus in advance without requiring manual pairing operations, thus improving ease of operation while maintaining communication reliability through subsequent pairing
Solution Approach 2:
The patent introduces first Bluetooth communication as an intermediary step between the terminal device and printing apparatus. This preliminary communication mode enables device identification and selection without requiring a full pairing connection, thereby simplifying the pairing process while ensuring reliable communication through the subsequent second Bluetooth communication mode
2Measurement precision
If touch event or manual interaction is required for device selection, then device identification accuracy is improved, but operation time and user burden increase
Solution Approach 1:
The patent replaces manual mechanical interaction (touch events, physical contact) with automated Bluetooth communication for device identification. The terminal device automatically identifies and selects the printing apparatus through wireless communication, eliminating the need for manual touch operations while maintaining accurate device identification
Solution Approach 2:
The system performs preliminary device identification and selection through first Bluetooth communication before the pairing connection is established. This allows the terminal device to automatically identify the target printing apparatus in advance, reducing the time required for the pairing process while ensuring accurate device selection
