Retractable VR Device with Movable Front Cover and Lens Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality devices are large and heavy due to mechanical and optical limitations, making them difficult to carry and store effectively.
Innovation Solution
A retractable virtual reality device design featuring a movable front cover relative to a rear cover, with restraining components and resilient mechanisms that allow the display module to adjust its configuration between a using and folding position, optimizing the spacing between display components and lens assemblies to reduce overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display component is spaced away from the lens assembly at a predetermined distance to meet focal length requirements, then the optical imaging quality is improved, but the device size and weight increase making it difficult to carry and store
Solution Approach 1:
The patent implements a movable front cover that can shift relative to the rear cover, allowing the display component to move between a using position (spaced from lens for optimal imaging) and a folding position (close to lens for compact storage). This dynamic reconfiguration resolves the contradiction by making the device size adaptable rather than fixed.
Solution Approach 2:
The front cover is designed to fold into the rear cover when not in use, with the display component nesting within the overall device structure. The restraining components allow the front cover to be contained within or alongside the rear cover, achieving a compact form factor that fits portable storage requirements while maintaining the ability to extend to the required optical spacing during use.
2Manufacturing precision
If the display component is spaced away from the lens assembly at a predetermined distance to meet focal length requirements, then the optical imaging quality is improved, but the device complexity increases due to additional restraining and operating components
Solution Approach 1:
The device is divided into distinct functional modules: a front cover containing the display component, a rear cover containing the lens assembly, and intermediate restraining components. This segmentation allows each part to be optimized independently while working together to achieve the overall function of adjustable optical spacing with controlled movement.
3Ease of operation
If the front cover is made movable to allow size adjustment for carrying and storage, then the ease of carrying and storage is improved, but the reliability decreases due to potential unintended movement of the display component
Solution Approach 1:
The restraining component is designed to automatically engage with the front cover when the device is folded or during normal use, providing self-locking functionality that prevents unintended movement without requiring active user intervention. The resilient component provides automatic reset capability, making the system self-regulating.

AI summary
A retractable virtual reality device includes a rear cover, a front cover, a first restraining component, a second restraining component, and a display module. The front cover is movably combined with the rear cover. The first restraining component is fixed on the front cover. The second restraining component is movably disposed on the rear cover and for restraining the first restraining component. The display module includes a sleeve, a lens, and a display. The sleeve is fixed on the rear cover. The lens is disposed on a side of the sleeve. The display is disposed on the front cover and movably combined with the other side of the sleeve. By cooperation of the first restraining component and the second restraining component, the display and the front cover are movable relative to the lens and the rear cover, which reduces an overall size of the virtual reality device for easy carry.
