Automatic Dual-Protocol Projection Search for Device Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies, such as DLNA-based and mirror projection, face challenges when devices are not on the same local area network or do not support the required protocols, leading to cumbersome and time-consuming user operations, and confusion in selecting the correct receiving device for projection.
Innovation Solution
The first electronic device automatically sends search requests for devices supporting different projection protocols, receives feedback messages indicating their capabilities, and displays identities and controls for both protocols together, allowing users to intuitively select the appropriate device without needing to switch ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DLNA-based projection and mirror projection are integrated into the same projection port, then projection versatility is improved, but device complexity increases and user confusion occurs due to multiple projection icons being displayed
Solution Approach 1:
The patent merges DLNA-based projection and mirror projection capabilities into a single projection port, allowing the device to search for and support both projection protocols through one unified interface instead of requiring separate ports or manual switching between different projection modes
Solution Approach 2:
The projection port is designed to support multiple projection protocols (DLNA and mirror projection) simultaneously, making it a universal interface that can adapt to different receiving devices based on their capabilities without requiring the user to manually configure or switch between different projection modes
2Reliability
If the user manually enables mirror projection function at system port to re-trigger searching, then projection capability is restored, but operation time increases and user effort increases
Solution Approach 1:
The system performs preliminary actions by automatically enabling both DLNA-based projection and mirror projection capabilities when the projection port is activated, and pre-configures the device to search for receiving devices supporting either protocol, eliminating the need for users to manually enable functions or re-trigger searches
Solution Approach 2:
The projection system provides self-service by automatically detecting which projection protocol the receiving device supports and selecting the appropriate protocol without requiring user intervention, manual configuration, or re-triggering of search functions, thereby reducing operation time and user effort

AI summary
Some embodiments include a first electronic device that automatically sends a first search request and a second search request. The first search request is used in a search for an electronic device having a first projection receiving capability related to a first projection protocol, and the second search request is used in a search for an electronic device having a second projection receiving capability related to a second projection protocol. In some embodiments the first electronic device receives a first feedback message or a second feedback message, or any combination thereof, from a second electronic device, and the first electronic device automatically displays, in response to the first feedback message, the second feedback message, the first identity related to the second electronic device.
