Solution Overview

Problem

Conventional eye-tracking devices are cumbersome, difficult to wear, and lack portability, especially when worn with eyeglasses, due to their complex structure and large size, which complicates their use across different subjects and environments.

Innovation Solution

A device adapted to standard eyeglasses with a removable adaption frame that secures eye-tracking sensors, featuring a central positioning mechanism with fasteners and flexible cushioning for comfortable fit and easy attachment/removal, allowing for improved portability and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional eye-tracking device is used, then eye-tracking functionality is achieved, but the device becomes complicated and occupies large space

Engineering Contradiction:
Improveeye-tracking functionalityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into separate modular components: an adaption frame with positioning means that can be independently attached to eyeglasses, and eye-tracking sensors that can be mounted on the adaption frame. This segmentation allows each component to be optimized independently and simplifies the overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An adaption frame serves as an intermediary component between the eyeglasses and the eye-tracking sensors. This mediator enables the integration of eye-tracking functionality without modifying the eyeglasses themselves, reducing complexity while maintaining functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a conventional eye-tracking device is used, then eye-tracking functionality is achieved, but wearing comfort deteriorates

Engineering Contradiction:
Improveeye-tracking functionalityVSAvoidwearing comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By separating the eye-tracking device into modular components that can be attached to standard eyeglasses, the device leverages the existing comfortable fit of the user's eyeglasses, avoiding the need for a custom-built heavy frame.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adaption frame is designed to be compatible with standard eyeglasses, allowing the same device to be used across different users and eyeglass types, improving ease of operation through universal compatibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If a conventional eye-tracking device is used, then eye-tracking functionality is achieved, but portability is reduced

Engineering Contradiction:
Improveeye-tracking functionalityVSAvoidportability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device can be detached into separate components (adaption frame and sensors), allowing users to remove the eye-tracking functionality when not needed, improving portability by enabling easy storage and transport.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device transitions from a fixed integrated structure to a dynamic configurable system where components can be attached and detached as needed, allowing the device to adapt between being worn and being stored, enhancing portability.

Inventive Principle:
Principle #15Dynamics

4Reliability

If a conventional eye-tracking device is used, then eye-tracking functionality is achieved, but wearing difficulty increases for eyeglass users

Engineering Contradiction:
Improveeye-tracking functionalityVSAvoidwearing difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The adaption frame acts as an intermediary that interfaces with standard eyeglasses using conventional attachment methods, allowing eyeglass wearers to add eye-tracking functionality without dealing with complex integration issues.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The device is designed to work with standard eyeglasses rather than requiring custom-made devices, making it universally applicable to eyeglass users and simplifying the wearing process through familiarity with standard eyeglass structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)
