Display Apparatus Updates for Casting Connection Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When information of a display apparatus changes, such as its name or network connection mode, the communication connection with a terminal device fails, leading to a poor user experience as the terminal device's casting list displays the original name and the user cannot control the display apparatus effectively.
Innovation Solution
The display apparatus is configured to send its updated network information to the terminal device upon detecting a change, allowing the terminal device to request and receive the updated device information, thereby re-establishing the communication connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus changes its device information (name, network connection mode), then the device information is updated, but the communication connection with the terminal device fails
Solution Approach 1:
The display apparatus proactively sends network information to the terminal device before the terminal device attempts to reconnect. This preliminary action allows the terminal device to generate an updated obtaining request with correct network information, preventing connection failure caused by outdated information.
Solution Approach 2:
The system implements a feedback mechanism where the display apparatus monitors its own device information changes and triggers a notification to the terminal device. This feedback loop ensures the terminal device receives real-time updates and can maintain reliable communication connection.
2Ease of operation
If the terminal device uses original device information to connect, then the connection was initially established, but the connection fails after device information changes
Solution Approach 1:
The display apparatus automatically detects its own device information changes and initiates the update process by sending network information to the terminal device. This self-service mechanism eliminates the need for manual intervention to maintain connection validity.
Solution Approach 2:
The display apparatus sends network information updates before the terminal device's connection attempt fails. This preliminary update ensures the terminal device has current information when it tries to reconnect, maintaining connection validity automatically.
3Stability of the object's composition
If the casting list displays the original name, then the user interface remains consistent, but the user cannot control the correct display apparatus
Solution Approach 1:
The terminal device receives feedback about device information changes from the display apparatus and updates the casting list accordingly. This feedback mechanism ensures the user interface reflects the current device state, allowing accurate device control.
Solution Approach 2:
The casting list dynamically updates based on received network information and device changes. Instead of remaining static with the original name, the interface adapts to reflect current device information, ensuring both consistency and control accuracy.
