Portable Terminal Multi-Scheme Wireless Device Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals only discover peripheral devices based on a single selected wireless communication scheme, making it inconvenient for users to find suitable devices for connection, especially when they are unaware of the communication schemes supported by other terminals.
Innovation Solution
A portable terminal that discovers and displays a list of wirelessly connectable devices across multiple supported wireless communication schemes, such as Bluetooth, Wi-Fi Direct, and wireless LAN, allowing users to easily establish connections in their preferred scheme.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable terminal selects one wireless communication scheme to discover peripheral terminals, then the device complexity is reduced, but the ease of operation deteriorates because users must manually select and understand different communication schemes
Solution Approach 1:
The patent combines multiple wireless communication scheme discovery processes into a single unified discovery operation. The terminal simultaneously or sequentially discovers devices across Bluetooth, Wi-Fi Direct, and other supported schemes through one user-initiated action, eliminating the need for users to manually select and switch between different discovery modes for each communication scheme.
Solution Approach 2:
The discovery mechanism is designed to be universal, handling multiple wireless communication schemes through a single interface. The terminal's discovery function serves multiple purposes by automatically attempting connection across different schemes (Bluetooth, Wi-Fi Direct, etc.) without requiring users to understand or manually configure each scheme separately, thus simplifying operation while maintaining multi-scheme capability.
2Productivity
If the terminal discovers devices in multiple wireless communication schemes simultaneously, then the productivity of device connection is improved, but the device complexity increases due to managing multiple communication protocols
Solution Approach 1:
The terminal performs preliminary discovery actions across multiple communication schemes before the user needs to establish a connection. By proactively scanning and identifying available devices in Bluetooth, Wi-Fi Direct, and other schemes in advance, the system prepares connection information ahead of time, enabling faster and more efficient device connection when the user initiates a file transfer or communication task.
