Wireless Display Auto-Connection via Signal Strength Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi connection methods for wireless devices are inconvenient as they require user intervention at each phase and lack guaranteed security, as they often involve unilateral access point attempts.
Innovation Solution
A display system and control method that automatically connects wireless devices by identifying signal strength and using Wi-Fi Protected Setup (WPS) product identification numbers, where devices exchange recognition signals and probe requests to establish secure connections based on threshold values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual Wi-Fi connection methods are used, then connection security can be controlled by user input, but user convenience deteriorates due to required intervention at each phase
Solution Approach 1:
The system enables automatic connection establishment between wireless devices by having devices autonomously perform signal strength comparison, connection determination, and connection establishment without requiring user input at each phase. The wireless terminal and display apparatus self-service the connection process by exchanging recognition signals and probe requests, comparing signal strengths against thresholds, and automatically establishing connections when conditions are met.
2Ease of operation
If automatic connection methods are implemented, then user convenience improves by eliminating intervention requirements, but connection security deteriorates due to unilateral connection attempts
Solution Approach 1:
The system implements a bidirectional feedback mechanism where both the display apparatus and wireless terminal actively transmit recognition signals and probe requests, then compare received signal strengths against predetermined thresholds. Each device provides feedback about its connection status and signal quality, allowing both parties to verify connection suitability before establishing the connection. This mutual verification process enhances security while maintaining automatic operation.
3Extent of automation
If signal strength threshold comparison is used, then automatic connection determination improves, but connection reliability deteriorates when signal strength varies
Solution Approach 1:
The system performs preliminary signal strength comparisons during the connection establishment phase by having devices exchange recognition signals and probe requests before final connection is made. Both devices compare signal strengths against predetermined thresholds in advance, allowing them to determine connection suitability before committing to the connection. This preliminary verification ensures that connections are only established when signal conditions are adequate, maintaining reliability while enabling automatic determination.

AI summary
A system and method of establishing a connection between a wireless terminal and a display apparatus of a display system includes comparing a signal strength of signals transmitted and received between the wireless terminal and the display apparatus, and automatically establishing the connection if it is determined that the signal strength is greater than or equal to a threshold value based on connection parameters in the signals
