Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple video streams from multiple cameras are synchronously combined into one display, then the quantity of video content is improved, but the aspect ratio proportionality and image quality deteriorate due to unintelligent resizing and cropping
Solution Approach 1:
The system dynamically adjusts the display configuration by allowing users to select from multiple preset aspect ratios (16:9, 4:3, 1:1, 2:1) and custom aspect ratios. The processing device automatically resizes and repositions video feeds based on the selected aspect ratio, enabling adaptive optimization of image proportionality while maintaining multiple video streams on the display.
Solution Approach 2:
The system changes the display parameters by processing video feeds through different aspect ratio transformations. The processing device receives video feeds and applies parameter changes including resizing, cropping, and repositioning based on selected aspect ratios, thereby maintaining proportionality while displaying multiple video streams simultaneously.
2Quantity of substance
If multiple video streams are combined into one display, then the quantity of video content is improved, but the device complexity increases due to processing requirements
Solution Approach 1:
The system performs preliminary actions by providing predefined aspect ratio options (16:9, 4:3, 1:1, 2:1) that are prepared in advance. When a user selects an aspect ratio, the processing device automatically applies the corresponding preprocessing transformations to video feeds, reducing the complexity of real-time processing while maintaining multiple video streams.
3Adaptability or versatility
If aspect ratio adjustment is implemented, then the adaptability of display is improved, but the device complexity increases due to software processing requirements
Solution Approach 1:
The system achieves universality by implementing a multi-functional processing device that handles multiple video feeds, applies various aspect ratio transformations, and supports different display configurations through a single integrated software solution. This universal approach enhances display adaptability while consolidating processing functions.
4Ease of operation
If automatic aspect ratio adjustment is implemented, then the ease of operation is improved, but the device complexity increases due to automated processing
Solution Approach 1:
The system implements self-service by automatically adjusting video feeds according to the selected aspect ratio without requiring manual intervention. When a user selects an aspect ratio option, the processing device autonomously performs resizing, cropping, and repositioning operations, thereby improving ease of operation while managing automated processing internally.
