Dual-Screen Head-Mounted Display With Adjustable Interpupillary Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual-reality head-mounted displays are difficult to adjust and wear comfortably, and single-screen designs can negatively impact image quality by not properly addressing the needs of both eyes.
Innovation Solution
A head-mounted display system with separate left and right display screens coupled to corresponding lenses, an adjustable strap system, and detachable audio subsystems to provide improved comfort and image quality through symmetric and flexible design elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single screen is used to provide images to both eyes, then the device complexity is reduced, but the image quality deteriorates
Solution Approach 1:
The patent divides the display system into separate left and right display screens, with each screen dedicated to one eye. This segmentation allows each screen to be optimized for its specific eye, improving image quality through proper stereoscopic separation while maintaining manageable device complexity through modular design
2Manufacturing precision
If the head-mounted display uses a fixed design, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent incorporates adjustable components that allow the interpupillary distance and screen positioning to be dynamically modified by the user. This enables the device to adapt to different users and conditions, improving ease of operation while maintaining manufacturing precision through standardized adjustment mechanisms
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
Enhances user experience by allowing for comfortable wear and improved image quality through adjustable interpupillary distance and separate screens for each eye, improving the overall virtual-reality experience.
Implementation Method 1
The left display screen is coupled to the left lens to provide images to the user's left eye through the left lens. The right display screen is coupled to the right lens to provide images to the user's right eye through the right lens.
