Folding Portable VR Headset with Exposed Smartphone Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable virtual reality devices using smartphones are bulky, heavy, and inconvenient to carry due to their large volume and weight, and they restrict the operation of the smartphone while in use, requiring the phone to be ejected for screen or program changes.
Innovation Solution
A portable virtual reality device with a folding structure that includes left and right supporting plates, fixing bars, and lens plates, where the board's length corresponds to the focal distance of the lenses, allowing the device to be compacted into a thin film for carrying, with exposed smartphone surfaces for operation and easy program changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional virtual reality device structure is used, then the device can provide virtual reality functionality, but the volume becomes large and weight becomes heavy making it inconvenient to carry
Solution Approach 1:
The device is divided into separate functional modules: lens assembly, smartphone mounting structure, and headband components. These segments can be assembled and disassembled independently, allowing the device to be compacted for portability while maintaining full functionality when assembled.
Solution Approach 2:
The device incorporates movable and adjustable components including adjustable headbands, flexible mounting mechanisms for smartphones, and collapsible structural elements. These dynamic features allow the device to transition between a compact portable state and an expanded functional state, resolving the contradiction between small volume and operational convenience.
2Weight of moving object
If a conventional virtual reality device structure is used, then the device can provide virtual reality functionality, but the weight becomes great making it difficult to wear on head for long times
Solution Approach 1:
The heavy processing and display components are extracted from the VR device itself and placed in the smartphone, which the user already carries. The VR device only contains lightweight optical lenses and mounting structures, dramatically reducing overall weight while maintaining full virtual reality functionality through the smartphone's processing power.
Solution Approach 2:
The device uses lightweight materials and thin-film constructions for the headband and mounting structures, replacing heavy rigid materials. This reduces weight while maintaining structural integrity and comfort for extended wear.
3Adaptability or versatility
If smartphone is mounted in the device while it is used, then virtual reality function is provided, but the smartphone cannot be operated or program cannot be changed while device is used
Solution Approach 1:
The smartphone is mounted in a way that leaves its screen and control interfaces accessible from the side or top dimension, rather than completely enclosing it. This allows users to interact with the smartphone's touchscreen and buttons while the device is worn, maintaining operational flexibility without complicating the mounting structure.
4Ease of manufacture
If conventional device structure is used, then virtual reality functionality is achieved, but manufacturing cost becomes high
Solution Approach 1:
The device is designed to work with any standard smartphone model, utilizing the smartphone's existing processor, display, camera, and sensors for virtual reality functionality. This universal approach eliminates the need for expensive custom-built processing units and display panels, significantly reducing manufacturing costs while maintaining reliable VR performance through the smartphone's proven components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device is significantly reduced in volume and weight, making it portable and convenient, with reduced manufacturing costs and allowing continuous smartphone operation during use.
Implementation Method 1
the length of the board corresponds to the distance as much as the smart phone is disposed at the focal distances of the left and right lens
Data Source
AI summary
A portable virtual reality device, which is provided with a board having a length to correspond the focal distances of the left and right lens; left and right supporting boards that are deployed and folded left and rightward on a front surface of the board based on the board; left and right lens plates that are deployed and folded left and rightward on a rear surface of the board based on the board. The smart phone is mounted simply to correspond to the focal distances of the left and right lens when it is used, and when it is carried, the left and right lens plates and the left and right supporting boards are fold to form a thin film to be carried conveniently.
