Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging protocol is closed during gameplay, then data transmission is stable, but the VR device cannot be charged
Solution Approach 1:
The patent segments the data transmission and charging functions into separate processing paths within the hub circuit. The hub circuit can independently handle data protocols while separately managing charging protocols, allowing both functions to operate simultaneously without interfering with each other. This segmentation enables the VR device to maintain stable data transmission while accepting charging input during gameplay.
Solution Approach 2:
The hub circuit is designed with multi-functionality to handle both data transmission and charging operations through a single interface. By implementing universal protocol matching capabilities, the hub circuit can identify and process different charging protocols (such as QC, FP, etc.) while simultaneously managing data communication, thus enabling the device to perform multiple functions without requiring separate dedicated circuits.
2Length of stationary object
If a long data line (exceeding 3 meters) is used, then connectivity is extended, but voltage drop loss increases
Solution Approach 1:
The hub circuit acts as an intermediary component between the data source and the VR device. It includes a voltage stabilizing circuit that compensates for voltage drops occurring in long data lines. By introducing this intermediary voltage regulation mechanism, the system can extend the data line length beyond 3 meters while maintaining sufficient voltage levels to prevent power depletion and ensure continuous gameplay.
3Duration of action of moving object
If the VR device is charged during gameplay, then power depletion is prevented, but charging protocol compatibility becomes complex
Solution Approach 1:
The hub circuit implements a feedback mechanism through protocol matching functionality. It continuously monitors and identifies the charging protocol type from the connected charging device, compares it with supported protocols, and automatically adjusts the charging parameters accordingly. This feedback-based protocol matching simplifies the complexity by providing automated adaptation rather than requiring manual configuration or multiple dedicated charging circuits for each protocol type.
