Sensing Eyewear Frame Nested Within Conventional Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyewear cannot be worn on top of another conventional eyewear, and sensing eyewear with sensors requires skin contact, making it difficult for users to wear both types simultaneously, especially in medical settings where patients often need to use conventional eyewear.
Innovation Solution
The development of new eyewear frames with a specialized configuration that includes a thin wire or plastic upper portion positioned above the eyebrow, allowing for a unique weight distribution and hardware placement in the temples, enabling the eyewear to be worn alone or with conventional eyewear, including underneath it, while providing sensing functions without visible bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional eyewear is worn on top of another conventional eyewear, then visibility and style are maintained, but it becomes impossible to wear both conventional and sensing eyewear simultaneously
Solution Approach 1:
The sensing eyewear frame is designed to be nested within or alongside conventional eyewear frames. The sensing frame components (temple, bridge, lens holder) are positioned to fit inside or adjacent to the conventional frame structure, allowing both types of eyewear to occupy the same spatial envelope without conflict.
Solution Approach 2:
The invention positions sensing eyewear components in the vertical dimension above the eyebrows, rather than in the horizontal plane where conventional eyewear resides. This vertical displacement creates separate spatial zones that eliminate interference between conventional and sensing eyewear while maintaining functionality of both.
2Measurement precision
If sensing eyewear requires skin contact for sensor function, then sensing accuracy is improved, but it becomes difficult to accommodate conventional eyewear that blocks sensor access
Solution Approach 1:
The eyewear system is segmented into distinct functional zones: the sensing frame provides skin contact at specific locations (temple, bridge, or lens holder), while conventional eyewear occupies other zones. This segmentation allows sensors to maintain skin contact for accurate measurement while conventional eyewear frames provide their protective and aesthetic functions without blocking sensor access.
3Reliability
If sensing eyewear includes visible hardware and bulk, then sensor functionality is enabled, but aesthetic appeal and discretion are reduced
Solution Approach 1:
The sensing eyewear employs local quality by concentrating sensor hardware and bulk components in specific localized areas (such as the temple or bridge) rather than distributing them throughout the entire frame. This allows the majority of the eyewear structure to maintain a sleek, minimal aesthetic while still providing adequate sensor functionality in the localized regions where bulk is acceptable.
4Strength
If conventional eyewear frames are thick and bulky, then structural strength is improved, but they prevent wearing over another pair of eyewear
Solution Approach 1:
The sensing eyewear frame employs asymmetric design where different portions of the frame have different thicknesses and structural characteristics. The temple and bridge areas may have sufficient thickness for sensor integration and strength, while the front frame and lens holder areas are minimized to be as thin as possible, allowing the sensing eyewear to fit over conventional eyewear while maintaining necessary structural strength in critical areas.
