Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless network connection is used for screen projection, then wired connection advantages are avoided, but transmission stability deteriorates due to network quality fluctuations
Solution Approach 1:
The patent introduces a dedicated wireless transmission device as an intermediary between the terminal device and display device. This mediator establishes a dedicated wireless transmission channel that is independent from the network infrastructure, thereby achieving both wireless convenience and transmission stability by eliminating network quality fluctuations as a factor.
2Ease of operation
If direct network connection between personal computer and large screen is established, then wireless transmission is achieved, but information leakage risk increases
Solution Approach 1:
The wireless transmission device serves as a secure intermediary that establishes a dedicated transmission channel independent from the network. This mediator prevents direct network connections between personal computers and display devices, thereby eliminating information leakage risks while maintaining wireless transmission capability through the dedicated channel.
Solution Approach 2:
The patent extracts the transmission function from the network infrastructure and places it in a dedicated wireless transmission device. By taking out the network dependency, the system eliminates the security vulnerabilities associated with network connections while preserving wireless transmission functionality.
3Adaptability or versatility
If display terminal runs remote conference software, then conference functionality is achieved, but device complexity increases
Solution Approach 1:
The patent introduces a wireless transmission device as an intermediary that handles all conference-related signal processing. This mediator absorbs the complexity of remote conference software functionality, allowing display terminals to remain simple without requiring software installation while still achieving full conference functionality through the intermediary device.
Solution Approach 2:
The patent extracts the conference software functionality from the display terminal and relocates it to a dedicated wireless transmission device. By taking out the software requirement from the display terminal, the system eliminates device complexity while preserving conference functionality through the specialized device.
4Speed
If display terminal processes audio-visual signals, then local display is achieved, but processing capability is insufficient causing delay and jamming
Solution Approach 1:
The wireless transmission device acts as an intermediary that performs all audio-visual signal processing operations. This mediator handles encoding, decoding, and signal processing tasks, allowing display terminals to simply receive and display signals without requiring complex processing capabilities, thereby eliminating delay and jamming issues.
Solution Approach 2:
The patent extracts the audio-visual signal processing function from the display terminal and places it in the wireless transmission device. By taking out the processing capability requirement from the display terminal, the system eliminates processing-related delays and jamming while maintaining local display functionality.
Data Source
AI summary
A multi-terminal conference system includes a receiving device connected with a camera and a display terminal, wherein the receiving device is configured to receive a captured content of the camera through a wireless mode so that the captured content can be used as a real-time capture image for uploading to a remote conference. The receiving device further receives a data information of the audio-visual signal corresponding to the remote conference software, decodes the data information to obtain the audio-visual signal corresponding to the data information, and transmits it to the display terminal to display the remote conference, so that the display terminal does not need to install and run any conference software and software driver while ensuring the effect and experience of the conference.
