Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless network connection is used for screen projection, then wired connection drawbacks (difficult wiring, cluttered wiring harnesses) are avoided, but transmission stability deteriorates due to network quality issues and protocol limitations
Solution Approach 1:
The patent introduces a dedicated wireless transmission device as an intermediary between the sending terminal and receiving terminal. This device establishes a direct wireless transmission channel that bypasses the unstable public network, providing both wiring convenience and transmission stability through dedicated infrastructure.
Solution Approach 2:
The transmission system is segmented into independent sending terminals, receiving terminals, and wireless transmission devices. Each component operates independently with dedicated functions, allowing stable local wireless transmission without being affected by network quality fluctuations.
2Ease of operation
If direct network connection between personal computer and large screen is used, then wireless transmission simplicity is achieved, but security risks worsen due to virus transmission and information leakage
Solution Approach 1:
The wireless transmission device serves as a secure intermediary that establishes a dedicated transmission channel. This intermediary isolates the personal computer from direct connection with the conference system, preventing virus transmission and information leakage while maintaining connection simplicity.
Solution Approach 2:
The patent extracts the transmission function from the network infrastructure and concentrates it in dedicated wireless transmission devices. This extraction creates secure, isolated transmission channels that prevent harmful factors like viruses and information leakage while maintaining operational simplicity.
3Adaptability or versatility
If display terminal runs remote conference program for video conferencing, then remote meeting functionality is achieved, but processing capability requirements worsen causing encoding/decoding delays and quality loss
Solution Approach 1:
The patent introduces dedicated transmission devices as intermediaries that handle encoding and decoding operations. These specialized devices offload the processing burden from the display terminal, enabling remote conference functionality without compromising processing efficiency or causing quality loss.
Solution Approach 2:
Instead of requiring the display terminal to run the complete remote conference program, the system transmits only the necessary video and audio streams to the display terminal. This copying approach provides remote conference functionality while minimizing processing requirements on the display terminal.
4Adaptability or versatility
If display terminal needs to install and run remote conference program, then remote participation is enabled, but device complexity worsens and information leakage risk increases
Solution Approach 1:
The wireless transmission device acts as an intermediary that provides remote participation capability without requiring software installation on the display terminal. The dedicated transmission channel handles all communication protocols, simplifying the display terminal's role to purely display-oriented functions.
Solution Approach 2:
The patent extracts the complex remote conference software functionality from the display terminal and relocates it to dedicated transmission devices. This extraction enables remote participation capability while significantly reducing device complexity and eliminating information leakage risks associated with installing unknown software.
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 recording content of the camera through a wireless mode so that the recording 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 program, 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 program and driver software while ensuring the effect and experience of the conference.
