Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transmission cable is used to connect the head-mounted VR display to a desktop computer, then the VR display can receive power and data, but the user's moving range is limited
Solution Approach 1:
The patent extracts the power supply function from the external desktop computer and relocates it into the head-mounted device itself by integrating a battery module. This allows the device to operate independently without being constrained by a transmission cable, thereby resolving the contradiction between reliable power supply and user mobility.
Solution Approach 2:
The patent transforms the static power supply arrangement (fixed connection to desktop computer) into a dynamic self-contained power system. The battery module enables the device to adapt to various user positions and movements, converting the system from cable-dependent to cable-free operation.
2Reliability
If a transmission cable is used to connect the head-mounted VR display to a desktop computer, then the VR display can process and display virtual reality images, but the user's use intention is reduced
Solution Approach 1:
The patent segments the VR system into two independent parts: a head-mounted display unit with integrated battery and processing capabilities, and a separate desktop computer for additional processing power. This segmentation allows the head-mounted unit to function autonomously, improving ease of operation while maintaining virtual reality image processing capability.
Solution Approach 2:
The head-mounted device is equipped with its own battery module and basic processing unit, enabling it to serve itself with power and initial image processing without constant dependency on the desktop computer. This self-service capability enhances user usability by allowing free movement while maintaining core VR functionality.
3Adaptability or versatility
If a battery module is integrated into the head-mounted device, then the device can operate wirelessly, but the device weight increases
Solution Approach 1:
The patent distributes the system components across different spatial dimensions: the battery module is integrated into the head-mounted device for wireless operation, while the desktop computer handles additional processing. This dimensional distribution allows the head-mounted unit to remain relatively lightweight while maintaining wireless capability.
4Device complexity
If the circuit board module and battery module are integrated into the hanging main body, then the device structure is compact, but heat generation from the circuit board module increases
Solution Approach 1:
The patent introduces a heat dissipation fan as an intermediary component between the circuit board module and the external environment. This fan actively removes heat generated by the integrated circuit board, allowing the compact integration of components while managing the thermal load effectively.
