Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If casting function is enabled without checking network status, then device complexity is reduced, but casting reliability deteriorates due to network disconnection failures
Solution Approach 1:
The patent applies preliminary action by checking network status and enabling Wi-Fi module before casting operation. The processor checks whether network is connected before receiving casting data, and enables network connection in advance if disconnected, ensuring casting reliability without adding complex real-time monitoring during data transmission.
Solution Approach 2:
The system performs self-service by automatically checking and enabling network connection when casting is detected. The processor autonomously determines network status and activates Wi-Fi module without user intervention, reducing the need for manual configuration while ensuring reliable casting operation.
2Reliability
If casting switch is not checked before receiving data, then device complexity is reduced, but casting reliability deteriorates due to switch being off
Solution Approach 1:
The patent applies preliminary action by checking casting switch status before receiving casting data. The processor determines whether casting switch is on in advance, and enables it if off, ensuring the casting function is ready before data transmission begins, thereby improving reliability without complex real-time control.
Solution Approach 2:
The system performs self-service by automatically checking and enabling casting switch when needed. The processor autonomously determines switch status and activates casting function without user intervention, reducing control complexity while ensuring reliable data reception.
3Reliability
If network connection is not enabled in advance, then device complexity is reduced, but casting reliability deteriorates due to disconnected network
Solution Approach 1:
The patent applies preliminary action by checking network connection status before casting operation and enabling network connection in advance if disconnected. The processor checks network status before receiving casting data and activates Wi-Fi module proactively, ensuring reliable network connection without complex real-time network management during data transmission.
Solution Approach 2:
The system performs self-service by automatically detecting and enabling network connection when casting is detected. The processor autonomously manages network status and activates Wi-Fi module without user intervention, reducing network management complexity while ensuring reliable data transmission.

AI summary
Disclosed are a display apparatus and a control method. The display apparatus includes: a communicator including a Wi-Fi module and a Bluetooth module and configured to communicate with a casting data source device; a display; a memory; and a processor. The processor is configured to perform: in response to a channel-switching instruction, switching from a current channel to a casting channel; in response to a casting instruction, checking a network status of the Wi-Fi module and a casting switch status; in response to the network status indicating that the network is disconnected, controlling the Wi-Fi module to enable network connection and to connect to a target network; and/or in response to the casting switch status indicating that a casting switch is off, controlling the casting switch to be turned on; and obtaining casting data via the target network, and displaying the casting data on an interface for the casting channel.
