Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a video multiplexer is used to multiplex multiple videos to generate an output video, then multi-image display is achieved, but the switching between different display modes requires complex manual operations
Solution Approach 1:
The display control apparatus automatically detects the current display mode and executes mode switching based on received instructions without requiring complex manual operations. The system serves itself by autonomously determining whether to switch between multi-image display and full-screen display modes, eliminating the need for users to perform complicated switching procedures.
Solution Approach 2:
The display control apparatus acts as an intermediary between the user and the video multiplexer. It receives user instructions, determines the appropriate display mode switching, and controls the video multiplexer accordingly, thereby simplifying the user interface while maintaining the underlying complex video processing capabilities.
2Reliability
If manual operations are required for display mode switching, then precise control is achieved, but user experience deteriorates due to complex operations
Solution Approach 1:
The system performs self-detection of the current display mode and automatically executes the appropriate switching logic. By detecting whether the current mode is multi-image display or full-screen display, the system maintains precise control while eliminating complex manual operations, thereby improving user experience without sacrificing control reliability.
Solution Approach 2:
The display control apparatus implements a feedback mechanism by detecting the current display mode and using this information to determine the appropriate switching action. This closed-loop control ensures that mode switching is both precise and automatic, resolving the contradiction between control reliability and ease of operation.
3Adaptability or versatility
If video multiplexing is performed for multi-image display, then multiple videos can be displayed simultaneously, but switching to full-screen display requires complex manual intervention
Solution Approach 1:
The display control apparatus implements dynamic mode switching by detecting the current display mode in real-time and automatically transitioning between multi-image display and full-screen display modes based on received instructions. This dynamic adaptation eliminates the need for complex manual intervention while maintaining versatility in display modes.
Solution Approach 2:
The display control apparatus serves multiple functions: it controls video multiplexing for multi-image display, manages full-screen display switching, and detects current display modes. This multi-functionality is achieved through a unified automatic control mechanism that simplifies operations while maintaining adaptability across different display modes.
