Optical Base Station Rotation Plate for Stable VR Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical base stations for virtual reality systems face challenges in scanning stability due to rotor misalignment and restricted scanning ranges, leading to increased volume and cost, as well as interference from circuitry and foreign particles.
Innovation Solution
The optical base station design fixes the input and output ends of the optical fiber on a rotation plate, ensuring the light beam is transmitted and output stably, with a rotation axis passing through the input end, allowing 360-degree scanning without vertical shifting and reducing volume by using a single rotation plate for dual light beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two rotors and two light sources are used to scan space, then scanning coverage is improved, but device volume and complexity increase
Solution Approach 1:
The patent combines two separate rotors and two light sources into a single integrated optical system. A single rotor carries both light sources and performs scanning in two different directions, merging previously separate scanning functions into one unified structure, thereby reducing device volume while maintaining comprehensive scanning coverage
Solution Approach 2:
The single rotor is designed to perform multiple scanning functions simultaneously by carrying two light sources that scan in different directions. This multi-functional design allows one component to replace what previously required two separate components, achieving both space saving and comprehensive scanning capability
2Adaptability or versatility
If rotors with reflectors are used for light beam scanning, then scanning capability is improved, but optical stability deteriorates due to misalignment
Solution Approach 1:
The patent extracts and eliminates the reflector component from the optical system. By using a direct transmission path where light passes through the rotor without reflection, the system removes the source of misalignment errors and optical instability that plagued the reflector-based design
Solution Approach 2:
The patent replaces the mechanical reflection system with an optical transmission system. Instead of using mirrors and reflectors that require precise mechanical alignment, the design uses direct light transmission through the rotor, substituting a mechanically sensitive system with an optically robust one
3Adaptability or versatility
If conventional optical base station design is used, then scanning function is achieved, but cost increases
Solution Approach 1:
The patent merges multiple expensive components (two rotors, two light sources, multiple reflectors) into a single, simpler optical system. This consolidation reduces the bill of materials and assembly complexity, directly lowering manufacturing costs while preserving the essential scanning function
Solution Approach 2:
The patent adopts a simpler, more cost-effective optical design that uses readily available components with straightforward assembly. The design prioritizes cost efficiency and ease of manufacture over complex, high-precision mechanical systems
