Smart Glasses Gaze Module With Clip Mount and Clear Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eye-tracking devices for smart glasses are not customizable to fit different somatic features, require nose pads that interfere with the user's nose and field of view, and are not easily attachable or detachable, leading to discomfort and reduced measurement accuracy.
Innovation Solution
A nose pad eye/gaze tracking module with a U-shaped portion housing sensors and a mechanical interface that attaches to the smart glasses without nose pads, allowing easy attachment and detachment, and is compact, lightweight, and non-intrusive, featuring sensors and electronic components for gaze tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional eye-tracking devices use nose pads for mounting, then the device can be securely attached to smart glasses, but the nose pads interfere with the user's nose and field of view causing discomfort
Solution Approach 1:
The patent removes the traditional nose pad mounting mechanism from the eye-tracking device. Instead of using nose pads that contact the user's nose, the device is mounted directly to the temple arms of the smart glasses via clips, completely eliminating the harmful contact with the nose and field of view obstruction
Solution Approach 2:
The patent introduces the temple arm of the smart glasses as an intermediary mounting surface. Rather than directly contacting the nose, the device attaches to the glasses frame itself, using the temple arm as a mediator that provides secure attachment without interfering with the user's nose or vision
2Reliability
If eye-tracking devices are designed with fixed mounting structures, then they can be securely attached to specific glasss frames, but they cannot be easily attached or detached and are not adaptable to different glasses models
Solution Approach 1:
The patent designs the eye-tracking device with universal clips that can attach to various temple arm configurations. The clips are engineered to accommodate different frame shapes, sizes, and materials, allowing the same device to be securely mounted on multiple models of smart glasses without requiring model-specific customization
Solution Approach 2:
The patent incorporates spring-loaded clips with adjustable tension that can dynamically adapt to different mounting surfaces. The elastic mechanism allows the clips to flex and conform to various temple arm geometries while maintaining secure attachment, enabling easy attachment and detachment across different glasses models
3Measurement precision
If eye-tracking devices include comprehensive sensors and processing units, then gaze tracking accuracy is improved, but the device weight and dimensions increase causing user discomfort
Solution Approach 1:
The patent integrates the eye-tracking sensors, processing unit, and power supply into a single compact module that attaches to the smart glasses. By merging all necessary components into one integrated unit, the design minimizes overall weight and dimensions while maintaining complete gaze tracking functionality, avoiding the need for separate distributed components
4Reliability
If eye-tracking devices use complex mounting mechanisms, then secure attachment is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent employs simple, inexpensive plastic clips as the mounting mechanism. These clips are designed to be easily manufactured and replaced if needed, providing secure attachment through simple elastic tension rather than complex mechanical interlocking. The simplicity of the clip design reduces manufacturing complexity and cost while maintaining reliable attachment
