Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to connect VR devices to docking stations, then data exchange stability is improved, but user mobility is restricted and data exchange rates are limited
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic communication system. Multiple array antennas transmit multimedia content wirelessly to the VR device, eliminating the physical cable constraint while maintaining data exchange stability through diversity combining of signals from multiple antennas.
2Reliability
If wired connections are used to connect VR devices to docking stations, then connection stability is improved, but data exchange rates are limited causing delayed rendering
Solution Approach 1:
The patent segments the data transmission system into multiple parallel wireless channels using multiple array antennas. Each antenna transmits data independently, and the VR device combines signals from all antennas, achieving higher aggregate data exchange rates while maintaining connection stability through redundant paths.
3Device complexity
If directional coverage antennas are used in VR devices, then device complexity is reduced, but interactive capabilities are reduced due to narrow aperture
Solution Approach 1:
The patent merges multiple directional antenna elements into array antennas with omnidirectional radiation patterns. By combining signals from multiple antennas arranged in specific geometries, the system achieves 360-degree coverage while maintaining the simplicity of individual antenna elements, thereby enhancing interactive capabilities without significantly increasing device complexity.
