Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transmission lines are used for power, image and data transmission in HMD systems, then reliable power and signal supply is achieved, but the system becomes bulky and uncomfortable for users
Solution Approach 1:
The patent combines power transmission, data transmission, and video stream transmission into a single USB Type-C transmission line. This merging of multiple transmission functions into one cable eliminates the need for separate transmission lines, thereby reducing the overall weight and bulkiness of the HMD system while maintaining reliable power and signal supply through the unified high-capability USB Type-C interface.
Solution Approach 2:
The USB Type-C transmission line serves multiple functions simultaneously: it provides power delivery, data communication, and video output capabilities. This multi-functional approach replaces traditional separate cables for each function, reducing the number of components needed and thereby decreasing the weight and bulk of the HMD system while ensuring reliable operation across all transmission needs.
2Reliability
If multiple separate transmission lines are used for power, data and video, then functional reliability is maintained, but device complexity increases
Solution Approach 1:
The patent merges power transmission, data transmission, and video stream transmission into a single USB Type-C transmission line. This consolidation reduces device complexity by eliminating the need for multiple separate transmission lines and their associated connectors and management circuits, while the USB Type-C interface's inherent capabilities ensure reliable power and signal supply.
Solution Approach 2:
The USB Type-C transmission line is designed to handle multiple functions simultaneously - power delivery, data communication, and video output - through a single unified interface. This multi-functionality reduces device complexity by replacing multiple specialized transmission lines with one versatile cable, simplifying the overall system architecture while maintaining transmission reliability.
3Weight of moving object
If USB Type-C transmission line is used for power, data and video transmission, then weight is reduced and maneuverability is improved, but signal quality must be maintained
Solution Approach 1:
The patent combines power, data, and video transmission into a single USB Type-C transmission line, which reduces HMD weight while maintaining signal quality. The USB Type-C interface's high-bandwidth capabilities ensure that video streams and data are transmitted reliably, and the power delivery function provides sufficient power, all through one lightweight cable replacement for multiple traditional cables.
Solution Approach 2:
The USB Type-C transmission line provides universal multi-functional support including power delivery, high-speed data transmission, and video output capabilities. This single cable replaces multiple traditional transmission lines, reducing HMD weight and improving maneuverability, while the interface's inherent design ensures high signal quality and reliable operation for all transmission functions.
