Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a projector establishes a connection with a video conference server and transmits authentication information, then video conference functionality is achieved, but usability deteriorates due to complex authentication requirements
Solution Approach 1:
The patent introduces a smartphone as an intermediary device between the projector and the video conference server. The smartphone handles authentication with the server, while the projector simply displays video content received from the smartphone. This mediator approach allows the projector to achieve video conference functionality without requiring direct authentication connections, thereby improving usability while maintaining reliability.
2Reliability
If authentication processes are implemented for device connection, then security is improved, but device complexity increases
Solution Approach 1:
The smartphone acts as an intermediary that centralizes authentication operations. Instead of multiple devices requiring separate authentication mechanisms, the smartphone handles all authentication with the video conference server, while the projector communicates only with the smartphone for video content. This reduces overall system complexity while maintaining security through centralized authentication management.

AI summary
An information processing system including a video device for displaying a video and a wireless terminal for communicating with the video device and communicating with other apparatuses via a network, wherein the video device transmits video information captured by a camera and sound information collected by a microphone when reception from the wireless terminal of information pertaining to a video to be displayed is detected, and outputs the received sound information using a speaker. The wireless terminal transmits information pertaining to the video to be displayed to the video device, the other apparatuses receive the captured video information and collected sound information via the network, and transmit information pertaining to the video to be displayed and information pertaining to the sound to be outputted.
