Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices require multiple cumbersome procedures to connect with external devices for function sharing, such as pairing and selecting devices, which is inconvenient.
Innovation Solution
A method and apparatus that automatically connect with external devices having a connection history, using a processor to detect volume key inputs and establish wireless connections, allowing the current function of the electronic device to be performed via the connected external device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic connection with external devices is implemented, then connection convenience is improved, but connection security and device selection control deteriorate
Solution Approach 1:
The system performs preliminary actions by storing connection history and device information in advance. When a volume key is pressed, the electronic device automatically retrieves and connects to a previously connected external device without requiring the user to go through pairing procedures again, thus improving connection convenience while maintaining security through pre-established trusted connections
Solution Approach 2:
The electronic device serves itself by automatically managing external device connections based on stored history. The device independently detects volume key inputs, retrieves connection history, selects appropriate external devices, and establishes connections without user intervention, thereby improving ease of operation while maintaining connection security through automated trusted device selection
2Reliability
If multiple connection procedures (pairing, selection) are required, then connection security is improved, but operation complexity increases
Solution Approach 1:
The invention extracts and separates the essential connection function from the complex multi-step pairing and selection procedures. By storing connection history and using volume key detection to automatically retrieve and execute connections to previously paired devices, the system removes the cumbersome intermediate steps while maintaining the security benefits of initial pairing
Solution Approach 2:
The system performs pairing and device selection actions in advance by storing connection history. When connection is needed, the pre-stored information is retrieved and used to automatically establish connections, eliminating the need for users to repeat pairing and selection procedures, thus reducing operational complexity while maintaining security

AI summary
A method for connecting with an external device and an electronic device thereof are provided. The method includes determining whether an input for increasing a volume is received is determined while the volume of the electronic device is at a maximum value. If the input for increasing the volume is received, an external device is detected, the electronic device connects with the external device, and the external device outputs an output associated with a current function of the electronic device.
