Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated computer applications with program codes are used to generate XR scenes, then XR scene generation capability is provided, but cross-platform compatibility is poor and device adaptability is limited
Solution Approach 1:
The patent uses a web environment (browser) as a universal platform that can run on multiple operating systems (Android, iOS, etc.) without requiring separate native applications. The browser acts as a multi-functional container that executes web-based XR content, eliminating the need to develop and maintain separate applications for each platform while maintaining consistent XR scene generation capabilities across devices.
Solution Approach 2:
The patent introduces a web environment (browser) as an intermediary layer between the user device and the XR content. This intermediary handles platform-specific adaptations internally, allowing developers to create XR scenes using standard web technologies without directly dealing with platform-specific APIs and compatibility issues. The browser mediates between the web-based XR content and the underlying operating system.
2Adaptability or versatility
If web environment is used to ensure cross-platform compatibility, then device adaptability improves, but access to operating system APIs is restricted and reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors device characteristics, sensor data, and XR scene performance. Based on this feedback, the system dynamically adjusts XR scene parameters, playback speed, and rendering quality to maintain stability and reliability across different web browsers and devices. This closed-loop control compensates for the limitations of web environment API access.
Solution Approach 2:
The patent dynamically changes various parameters of the XR scene including playback speed, rendering resolution, and scene complexity based on device capabilities and performance metrics. By adjusting these parameters in real-time, the system maintains reliable and stable XR scene generation across different web environments and devices, compensating for restricted API access through adaptive parameter optimization.
