Variable Aperture VR Lens Barrel for Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality lens barrel assemblies fail to provide optimal immersion due to the inability to match display areas of different sizes, leading to reduced user experience.
Innovation Solution
A virtual reality lens barrel assembly with a blocking mechanism featuring a through hole of variable size, adjustable via a sleeve and hinges, ensures the view range matches the display area size, using a tubular structure with a lens and display assembly, and includes an adjusting knob for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size lens and display assembly are used, then the structure is simple, but the immersion is reduced when display area sizes vary
Solution Approach 1:
The patent applies the dynamics principle by making the lens barrel length adjustable through a telescopic mechanism. The lens barrel can extend or retract to different lengths, allowing the optical system to adapt to display assemblies of various sizes. This dynamic adjustment capability enables the VR device to maintain optimal immersion across different display configurations without requiring multiple fixed lens assemblies.
2Adaptability or versatility
If a telescopic lens barrel is used to match different display areas, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements the nesting principle through the telescopic lens barrel structure, where inner barrel segments are nested within outer barrel segments. This allows the lens barrel to compactly store multiple length configurations in a single integrated structure. The nested design enables smooth extension and retraction movements while maintaining a compact form factor, reducing the overall device complexity compared to using multiple separate lens assemblies.
Solution Approach 2:
The telescopic lens barrel serves multiple functions: it acts as both a structural support element and an adjustable optical component. The same lens barrel mechanism that provides telescopic movement also functions as the mounting structure for the lens and display assembly, eliminating the need for separate adjustment mechanisms and reducing overall device complexity.
