Smart Glasses Gaze Module With Temple Mount and U-Shaped Sensors
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 U-shaped sensors and a mechanical interface that attaches to the smart glasses without nose pads, allowing easy attachment and detachment, customizable to various nose shapes, and positioned to avoid interference with the nose and field of view, using compact and lightweight design with internal electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional eye-tracking devices use nose pads to attach to smart glasses, then the device can be securely fastened, but it interferes with the user's nose and field of view causing discomfort
Solution Approach 1:
The patent removes the traditional nose pad component from the attachment system. Instead of using nose pads that contact and interfere with the user's nose, the invention extracts this harmful element and replaces it with a temple-based attachment mechanism that secures the device to the glasses without contacting the nose, thereby eliminating discomfort while maintaining secure fastening
Solution Approach 2:
The patent introduces the temple of the smart glasses as an intermediary element for attachment. Rather than directly attaching to the nose (harmful path), the device uses the temple as a mediator to achieve secure fastening. The attachment mechanism engages with the temple structure, transferring the securing function from the nose-contacting nose pads to the temple-based interface, thus resolving the contradiction between secure attachment and user comfort
2Ease of manufacture
If eye-tracking devices are designed with fixed frame structures, then manufacturing is simplified, but they cannot be customized to fit different somatic features of various ethnic groups
Solution Approach 1:
The patent creates a universal attachment mechanism that can accommodate different somatic features and ethnic group variations. The temple-based attachment system serves multiple functions: it secures the device, adapts to different face shapes and nose structures, and provides customization without requiring different manufacturing models. This single universal design replaces the need for multiple customized frame structures, maintaining manufacturing simplicity while achieving broad adaptability
Solution Approach 2:
The attachment mechanism incorporates dynamic elements that allow adjustment and adaptation to different user anatomies. The quick-release feature and flexible positioning capability enable the same device to be customized for different nose shapes and facial structures through user-adjustable parameters rather than requiring different manufactured frames, thus maintaining ease of manufacture while achieving customization
3Strength
If nose pads are used to attach the eye-tracking module, then the device can be firmly attached to the glasses, but it occupies space and interferes with the user's nose and field of view
Solution Approach 1:
The patent extracts the attachment function from the nose pad location and relocates it to the temple area. By removing the nose pad component entirely and using the temple as the attachment point, the device achieves firm attachment strength without occupying space near the user's nose, thereby eliminating the interference with both nose comfort and field of view while maintaining secure fastening
4Device complexity
If traditional smart glasses frames are used, then the structure is simple and familiar, but they cannot easily accommodate customizable nose pads for different users
Solution Approach 1:
The patent enhances the traditional simple frame structure by integrating a universal temple-based attachment mechanism that provides customization capability. The temple serves multiple functions: structural support, attachment interface, and customization platform. This approach maintains the simplicity of the traditional frame while adding adaptability through the universal attachment system that can be adjusted for different users without complicating the overall frame structure
