Spectacles Optical Display System Lateral Edge Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display systems for virtual reality are bulky and obstruct the view of the external environment, while attempts to integrate optical display systems into common spectacles have resulted in designs that are either incompatible with standard spectacles or compromise the quality of vision.
Innovation Solution
The design incorporates a spectacle system with a face that includes at least one lens-type optical unit, featuring a module for emitting visual information, an optical transformation element, and a mirror-type element for geometric reflection. This configuration minimizes bulk and obstruction by positioning the emitting module and geometric reflection element near the nose joint, allowing for a high-quality image projection without obstructing direct vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display system is positioned horizontally over the bridge of the nose, then the optical display function is achieved, but the design becomes incompatible with common spectacles and increases bulk
Solution Approach 1:
The patent repositions the display system from a horizontal arrangement over the bridge of the nose to a vertical arrangement along the lateral edge of the spectacle lens. This dimensional change allows the optical components to be integrated into the side profile of the spectacles, maintaining compatibility with common spectacle designs while reducing the horizontal bulk that would interfere with the bridge area and overall adaptability.
2Ease of operation
If the display system is integrated into the spectacle lens, then the optical display function is achieved, but the image is projected at the periphery of the lens requiring eye movements that obstruct clear view of the environment
Solution Approach 1:
The patent positions the display system and optical components specifically at the lateral edge of the spectacle lens rather than distributing them across the entire lens surface. This localized arrangement allows the image to be projected to a specific target area that can be viewed without requiring peripheral eye movements, thereby maintaining clear central vision of the environment while enabling display functionality.
3Volume of moving object
If the optical system is designed to minimize space occupation, then compactness is improved, but the quality of vision and image projection may be compromised
Solution Approach 1:
The patent employs adjustable optical elements including a movable mirror and adjustable lens that can be positioned along the optical path. These dynamic components allow the system to maintain high image projection quality by optimizing the optical path length and focus, while the compact housing integrates these adjustable mechanisms within a minimal space footprint along the lateral edge of the lens.

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 solution effectively reduces the space occupied by the optical system while maintaining the standard characteristics of common spectacles, such as size, compactness, and lightness, and ensures that the view of the environment is not obstructed, providing a clear and unimpeded field of vision.
