Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional CAVE systems are used, then immersive VR functionality is achieved, but the systems become expensive, heavy, and difficult to assemble
Solution Approach 1:
The CAVE system is divided into modular components including a collapsible support structure, separate projection surfaces, and independent projector units. Each component can be assembled and disassembled independently, reducing the overall assembly complexity while maintaining the immersive VR functionality when configured together.
Solution Approach 2:
The system includes self-contained mounting mechanisms and alignment features that enable users to assemble and configure the CAVE without requiring specialized tools or extensive technical expertise. The support structure incorporates built-in adjustment mechanisms that allow users to position projectors and screens without professional calibration equipment.
2Reliability
If conventional CAVE systems are used, then immersive VR functionality is achieved, but the systems become cumbersome and not portable
Solution Approach 1:
The support structure transitions from a static, permanent installation to a dynamic, collapsible framework that can be easily assembled and disassembled. The structure incorporates telescopic elements and removable connections that allow the CAVE to be configured for use and then collapsed into a compact form for portability, reducing weight and storage requirements while maintaining VR functionality.
3Reliability
If conventional CAVE systems are used, then immersive VR functionality is achieved, but the systems require specialized calibration and trained personnel for setup
Solution Approach 1:
The system incorporates automated alignment features and visual alignment aids that provide real-time feedback during assembly. The support structure includes adjustable mounting positions with indicator markings that guide users in properly positioning projectors and screens. The system may include software tools that automatically detect component positions and suggest adjustments, eliminating the need for professional calibration while ensuring proper configuration.
4Reliability
If conventional CAVE systems are used, then immersive VR functionality is achieved, but the systems are not compatible with other VR platforms
Solution Approach 1:
The CAVE system is designed with universal mounting interfaces and standardized connection protocols that are compatible with multiple VR platforms and graphics processing units. The support structure incorporates adjustable mounting positions that can accommodate different projector types and resolutions. The system includes software frameworks that can interface with various operating systems and VR development platforms, enabling the same hardware to support different VR applications and extensions.

AI summary
A portable CAVE automatic virtual environment system. The system uses a light weight collapsible frame with an overhead beam that is raised and lowered via a lockable hinge on each of the vertical supports. Ultra-short throw projectors are attached to the overhead beam at its lowest position and are raised to their functional position where they are automatically configured to aim at one of the included screens. The projectors display imagery on the screens that form a space around the user. The system auto-calibrates to align the projected imagery to the screens to form a seamless display across all screens. The invention significantly decreases the time and labor to set up and calibrate a CAVE system and collapses into folded parts for easy transport and storage.
