Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality (VR) devices have limited functionality and eye protection instruments for reducing myopia are complex and inflexible, failing to effectively adjust the imaging face to prevent vision deterioration from prolonged close-distance viewing.
Innovation Solution
A wearable display device equipped with a motor, processor, and motor drive assembly that adjusts the imaging face by rotating based on received control instructions, including rotation mode and speed parameters, allowing for flexible eye protection and enhanced functionality beyond basic VR use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wearable display device is designed to provide basic VR functionality only, then the device structure remains simple, but the device lacks eye protection functionality and is insufficient for preventing vision deterioration
Solution Approach 1:
The wearable display device integrates both VR display functionality and eye protection functionality into a single device. The motor assembly enables the imaging face to move between a first position (VR mode) and a second position (eye protection mode), allowing the device to perform multiple functions without requiring separate devices for each purpose.
2Object-affected harmful factors
If an eye protection instrument is designed with multiple adjustment mechanisms, then the eye protection functionality is enhanced, but the operation becomes complex and inflexible
Solution Approach 1:
The eye protection device uses a motor-driven mechanism to dynamically adjust the position of the imaging face. Instead of multiple static adjustment mechanisms, a single motor can programmatically move the imaging face to different positions, providing flexible and adaptive eye protection that responds to user needs without complex manual adjustments.
3Object-affected harmful factors
If the imaging face position is fixed, then the device structure is simple, but the device cannot adjust to prevent vision deterioration from prolonged close-distance viewing
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with an electric motor-driven system. The motor receives control instructions to automatically adjust the imaging face position, substituting manual mechanical operations with automated electromagnetic actuation, thereby reducing mechanical complexity while enabling dynamic vision protection.
