Eyeglass Frame Micro-Display Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional head-mounted displays (HMDs) are bulky and clumsy, making them unsuitable for comfortable wear and aesthetic appeal.
Innovation Solution
A wearable electronic display system featuring an eyewear frame with a micro-display module that is integrated into a conventional eyeglasses design, including adjustable components for interpupillary distance and optical axis alignment, with an elongate display module and image exit window positioned for comfortable viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional head-mounted displays are used, then display functionality is provided, but the device becomes bulky and clumsy
Solution Approach 1:
The display module is nested within the eyewear frame structure, with the micro-display and optical components integrated into the existing eyeglass design. The elongate portion of the display module is positioned within the frame, allowing the display functionality to be contained within the familiar eyewear volume, thus reducing overall bulk while maintaining comfort of wear.
Solution Approach 2:
The display module is oriented with its elongate portion extending laterally along the level of the frame members, and the image exit window is tilted in upwardly or downwardly directions. This dimensional reorientation allows the display to utilize the three-dimensional space of the eyewear frame more effectively, reducing the need for a large frontal profile and improving wearability.
2Shape
If traditional head-mounted displays are used, then display functionality is provided, but the device looks odd to wear
Solution Approach 1:
The display module is merged with the eyewear frame structure, where the elongate portion of the display module has generally comparable width and/or thickness as the eyewear rims. The display module is positioned to extend laterally generally along the level of the frame members, causing the display device to blend with the conventional eyeglasses appearance, thus improving aesthetic appeal while maintaining comfort of wear.
Solution Approach 2:
The display module is positioned specifically at certain locations within the eyewear frame, with the image exit window tilted in specific directions (upwardly or downwardly). This localized positioning and orientation allows the display to be integrated into the frame structure in a way that preserves the natural appearance of conventional eyeglasses while providing the desired display functionality.
3Measurement precision
If the display module is positioned for optimal viewing, then image quality is improved, but the device becomes less adaptable to different users
Solution Approach 1:
The eyewear frame is provided with adjustment mechanisms including a center bridge with adjustable width for interpupillary distance (IPD) adjustment, and a pivot mechanism that allows the front frame portion to be tilted relative to the side frame portions. These dynamic adjustment capabilities allow the display module to be repositioned to optimize viewing quality for different users while maintaining adaptability.
Solution Approach 2:
The device allows for parameter changes in the positioning of the display module and frame components. The image exit window can be tilted in upwardly or downwardly directions, and the front frame portion can be adjusted in position and angle. These parameter adjustments enable optimization of image viewing quality for different users while maintaining versatility.
