Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used for data transmission between wearable display devices and control devices, then data transmission rate and reliability are improved, but user mobility is restricted and line disconnection may occur due to movement
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic field-based communication system. Specifically, it uses mmWave RF signals for display data transmission and lower frequency RF signals for control signal transmission, eliminating physical cables and thereby restricting neither user mobility nor compromising transmission reliability through dual-channel wireless communication
2Ease of operation
If existing wireless communication technologies are used, then user mobility is improved, but data transmission rate is insufficient for ultra-high-resolution displays and real-time sensor data
Solution Approach 1:
The patent segments the wireless communication system into two distinct frequency channels: mmWave (30-300 GHz) for high-bandwidth display data transmission and lower frequency RF (3-30 GHz) for control signals. This segmentation allows each channel to be optimized for its specific function, with mmWave providing ultra-high speed data transmission capable of supporting 8K displays and VR/AR applications while maintaining user mobility
Solution Approach 2:
The patent transitions from traditional single-frequency wireless communication to multi-frequency band communication by utilizing the mmWave spectrum dimension (30-300 GHz) in addition to lower RF bands. This dimensional expansion of the frequency spectrum enables dramatically higher data transmission rates while preserving the wireless mobility advantage
3Productivity
If dual-frequency wireless communication is implemented, then data transmission capability is improved, but device complexity and hardware requirements increase
Solution Approach 1:
The patent implements a universal dual-channel wireless communication system where the device can simultaneously handle both mmWave and lower frequency RF communications through integrated transceivers. The system universally supports multiple functions: high-speed display data transmission via mmWave, control signal transmission via lower RF, and automatic interface detection, all within a single unified communication architecture that manages complexity through standardized protocols
4Adaptability or versatility
If additional hardware or conversion protocols are added for wireless communication, then transmission compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a self-service interface detection and adaptation mechanism where the communication system automatically detects the display interface type (HDMI, DisplayPort, V-by-One, etc.) and configures the appropriate transmission parameters without requiring additional external conversion hardware or complex manual configuration. The system self-adapts to support multiple display interfaces through integrated detection circuits and protocol handlers, maintaining compatibility while minimizing added complexity
