Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If an electronic device shares screen and audio signals from multiple applications with another device, then the quantity of shared content increases, but the device complexity increases
Solution Approach 1:
The patent segments the audio sharing system by creating separate audio session channels for different applications. Each application's audio is routed through independent audio tracks that can be individually controlled, allowing multiple applications to share audio simultaneously without requiring a complete system redesign. This segmentation enables scalable multi-application audio sharing while maintaining manageable system complexity.
Solution Approach 2:
The audio session manager is designed as a universal component that handles audio routing for any application through a standardized interface. The system provides multi-functional capability by supporting both screen sharing and independent audio sharing from multiple applications through the same infrastructure, eliminating the need for separate dedicated systems for different sharing scenarios.
2Ease of operation
If an electronic device enables independent volume control for each application, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The audio control system is segmented into independent volume control channels, with each application having its own adjustable volume track. This allows users to control each application's audio independently through a simplified interface, while the complex mixing and routing operations are handled automatically by the audio session manager in the background, separating user-facing simplicity from system-level complexity.
Solution Approach 2:
The audio session manager acts as an intermediary layer between the user interface and the audio output hardware. It mediates between simple user volume adjustments and the complex multi-track audio mixing required for simultaneous application audio, absorbing the computational complexity while presenting a simple control interface to users.
3Productivity
If an electronic device transmits multiple audio signals simultaneously, then the productivity increases, but the loss of information increases
Solution Approach 1:
The audio transmission system segments multiple audio signals into distinct, labeled tracks corresponding to different applications. Each audio signal is transmitted with metadata identifying its source application, preventing confusion or loss of information about which audio belongs to which application. This segmented approach enables simultaneous transmission of multiple audio streams while maintaining complete information integrity.
Solution Approach 2:
The system implements feedback mechanisms where the receiving device can identify and distinguish between multiple incoming audio streams through unique identifiers. This feedback loop ensures that each audio signal is properly routed and associated with its source application, preventing information loss even when multiple audio signals are transmitted simultaneously through the same communication channel.

AI summary
According to an embodiment, in response to receiving a first designated request from another electronic device while outputting a first screen and first audio, at least one processor of an electronic device, individually and/or collectively, may be configured to control the electronic device to transmit a first signal and a second signal for outputting the first screen and the first audio by the other electronic device, respectively. While transmitting the first signal and the second signal, at least one processor may individually and/or collectively be configured to control the electronic device to receive, from the other electronic device, a second designated request for executing a second application distinct from the first application related to the first audio. In response to the second designated request, at least processor, individually and/or collectively may be configured to control the electronic device to transmit a third signal and a fourth signal, which are related to a second screen of the second application and second audio, respectively, to the other electronic device together with the first signal and the second signal.
