Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video compositing is performed using separate devices and additional tasks, then video compositing functionality is achieved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple video processing functions (video capture, background video integration, object selection, and compositing) into a single integrated system within the mobile terminal. The processing circuitry performs all compositing operations locally without requiring external devices, thereby simplifying the user workflow while maintaining comprehensive functionality.
Solution Approach 2:
The mobile terminal's processing circuitry is designed to perform multiple functions: capturing user videos, receiving background videos, selecting target objects, generating converted videos, and compositing these elements in real-time. This multi-functional approach eliminates the need for separate dedicated compositing devices.
2Productivity
If real-time video compositing is performed without additional devices, then ease of operation improves, but processing power and device complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-processing video streams and pre-selecting target objects during video capture. The processing circuitry prepares converted videos in advance by removing background portions before the final compositing operation, enabling real-time performance without last-minute computational overhead.
Solution Approach 2:
The video processing is divided into distinct segments: user video capture, background video reception, target object selection, converted video generation, and final compositing. This segmentation allows each processing stage to be optimized independently, managing computational complexity while maintaining real-time throughput.
3Productivity
If video compositing requires additional tasks, then manufacturing precision is maintained, but ease of operation and productivity worsen
Solution Approach 1:
The processing circuitry automatically performs video compositing operations without requiring manual intervention for each step. The system autonomously captures videos, selects target objects, generates converted videos, and composites them, eliminating the need for users to perform multiple separate tasks while maintaining high production efficiency.
