Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used to connect computer to projector, then stable image transmission is achieved, but cable length constraint and device switching complexity increase
Solution Approach 1:
The patent introduces a wireless communication intermediary system consisting of a wireless transmitter in the computer and a wireless receiver in the projector. This intermediary wireless communication channel replaces the direct wired connection, enabling stable image transmission without physical cable constraints and allowing seamless switching between multiple devices through automatic connection management.
2Stability of the object's composition
If wired connection is used, then connection stability is maintained, but flexibility in speaker positioning and device switching is reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The wireless transmitter and receiver establish an electromagnetic connection that maintains stability through protocol management while eliminating the physical cable that constrained speaker positioning. This allows speakers to move freely within wireless coverage areas and switch between multiple computers without physical reconnection.
3Reliability
If multiple speakers use wired connections, then each connection is reliable, but the complexity of switching between speakers increases
Solution Approach 1:
The patent implements automatic connection management where the wireless communication system automatically detects available computers, establishes connections, and switches between speakers without manual intervention. The system self-manages the complexity of handling multiple connections through automatic pairing, connection maintenance, and seamless switching protocols.

AI summary
An interactive display system, an operation method thereof, and an image intermediary apparatus are provided. The image intermediary apparatus is adapted to at least divide a display area of an interactive display apparatus into a first frame region and identify external electronic apparatuses to establish a correspondence relation between the external electronic apparatuses and image signals of the external electronic apparatuses, and display a first image based on a first image signal among the image signals of the external electronic apparatuses on the first frame region. When interactive position information indicates that an interactive event occurs on the first frame region, the image intermediary apparatus acquires a communication identification information corresponding to the first image signal according to the correspondence relation, and transmits a coordinate corresponding to the interactive position information to an external electronic apparatus corresponding to the communication identification information among the external electronic apparatuses.
