Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image processing operations are performed on captured images to enhance user experience and provide various features, then image quality and functionality are improved, but computational complexity and processing time increase significantly
Solution Approach 1:
The patent applies preliminary action by performing image processing operations during the capture phase rather than as post-processing. The system processes images immediately when captured, enhancing them with filters, adjustments, and effects before storage or transmission. This approach maintains high image quality while distributing computational load across multiple devices (camera device, server, client devices) rather than concentrating it in a single post-processing step.
2Adaptability or versatility
If complex image processing operations are performed on captured images, then various features and enhanced user experience are provided, but processing time and latency increase
Solution Approach 1:
The patent applies segmentation by dividing the image processing workflow into distinct phases and locations: (1) initial capture and basic processing at the camera device, (2) selective enhancement operations on server infrastructure, and (3) final rendering and delivery to client devices. This segmentation allows different types of processing to occur in parallel across multiple systems, reducing overall processing time while maintaining feature variety.
Solution Approach 2:
The system performs preliminary image processing and enhancement operations before the images are fully processed and delivered to users. By pre-processing images with filters, adjustments, and effects during capture and initial transmission, the system reduces the computational burden on client devices and decreases final processing latency.
3Ease of operation
If real-time media overlay application is implemented, then user interaction and customization are improved, but system resources and computational power are consumed
Solution Approach 1:
The patent applies partial action by implementing media overlay functionality selectively rather than universally. The system provides real-time media overlay application only when users actively engage with the feature, allowing them to choose specific overlays for their images. This selective implementation reduces overall computational resource consumption while maintaining ease of operation for users who want this functionality.
