Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional spectacles with cameras for measuring eye behavior are conspicuous, influence user behavior, and pose safety risks due to protruding parts, limiting their use in public and hazardous environments, while also compromising measurement accuracy.

Innovation Solution

Design of spectacles with eye acquisition cameras integrated into the nose frame parts, allowing binocular measurement of both eyes, reducing the influence on user behavior and enhancing measurement accuracy, and enabling inconspicuous wear in hazardous environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a camera is arranged on spectacles to record eye behavior, then measurement capability is achieved, but the spectacles become conspicuous and influence user behavior

Engineering Contradiction:

Improveeye behavior measurement capabilityVSAvoidinfluence on user behavior

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by integrating cameras specifically into the nose frame parts rather than using conventional front-mounted cameras. This localized placement allows the measurement function to be achieved while the rest of the spectacles appearance remains normal, reducing the psychological impact on users and eliminating behavioral influence.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If cameras and cables are arranged on spectacles for measurement, then measurement function is achieved, but protruding parts create safety risks in hazardous environments

Engineering Contradiction:

Improveeye behavior measurement capabilityVSAvoidsafety risks from protruding parts

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent merges the camera housing with the nose frame structure, making the camera an integral part of the spectacles frame rather than a separate protruding component. This integration eliminates dangling cables and external protrusions, allowing the spectacles to be worn safely in hazardous environments near rotating machinery.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If a camera is arranged on the front of spectacles to record the eye, then measurement is possible, but measurement accuracy is compromised

Engineering Contradiction:

Improvemeasurement operation capabilityVSAvoidpupil detection accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent inverts the conventional camera placement approach by moving the camera from the front of the spectacles to the nose frame parts. This inversion changes the recording angle from bottom-front to a more optimal position that improves pupil detection accuracy while maintaining measurement functionality.

Inventive Principle:

Principle #13The other way round (Inversion)
