Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wired auxiliary stream sharing is used, then audio and video data can be transferred reliably, but device compatibility is limited and mobility is restricted
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The auxiliary stream device uses wireless interfaces (Wi-Fi, Bluetooth) to transmit audio and video data to the master device, eliminating the need for physical cable connections and enabling broader device compatibility including tablets and mobile devices.
Solution Approach 2:
The patent creates a universal auxiliary stream sharing system that works across multiple device types (PCs, laptops, tablets, mobile devices) with different interfaces. The master device can receive auxiliary streams from various sources through standardized wireless protocols, making the system universally applicable without requiring device-specific cable connections.
2Ease of operation
If wired network transmission is used, then data transfer stability is maintained, but mobility and flexibility during presentation are reduced
Solution Approach 1:
The patent substitutes the wired network transmission system with wireless transmission using Wi-Fi and Bluetooth protocols. This allows the auxiliary stream device to be freely positioned and moved during presentation while maintaining stable data transfer through wireless communication, eliminating the physical constraint of cable connections.
3Adaptability or versatility
If wireless transmission is implemented, then device compatibility and mobility are improved, but transmission stability may be affected
Solution Approach 1:
The patent introduces a screening software as an intermediary component that manages the wireless transmission process. This software handles the complexity of wireless communication, ensures stable data transfer, and coordinates between the auxiliary stream device and master device, thereby maintaining transmission reliability while enabling wireless connectivity.
