Adjustable Optical Element in Head-Mounted Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices have a fixed image display position, which may not be optimal for all users due to variations in physique or how the device is worn, leading to suboptimal viewing experiences.
Innovation Solution
A head-mounted display device equipped with an optical element and a drive mechanism that allows the optical element to move in a direction intersecting with the user's visual line, enabling adjustable image display positions within the user's field of view, controlled by a program that communicates with the image supply device to adjust the image formation distance and display position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed display position is used in head-mounted display devices, then the device structure is simple, but the viewing experience is suboptimal for users with different physiques or wearing methods
Solution Approach 1:
The patent applies the dynamics principle by making the optical element movable rather than fixed. The optical element can be adjusted in position along the visual line direction to accommodate different user physiques and wearing methods, thereby improving viewing experience while adding adjustment mechanisms to the device structure.
2Adaptability or versatility
If an adjustable optical element is added to change image display position, then viewing comfort is improved, but device complexity increases
Solution Approach 1:
The optical element is designed to be dynamically adjustable through a drive mechanism that allows movement in the visual line direction. This enables the device to adapt to different user anatomies and wearing styles while providing personalized viewing comfort through position adjustment capabilities.
3Adaptability or versatility
If the optical element is made movable to adjust image position, then personalized viewing is enabled, but the device structure becomes more complex
Solution Approach 1:
The patent implements a movable optical element with drive mechanisms that enable personalized display adjustment. The optical element can be repositioned along the visual line direction to match individual user characteristics, providing customized viewing experiences while incorporating necessary mechanical adjustment systems.
