Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing ophthalmic devices for dyslexia, such as those with colored filters, do not effectively address the asymmetry between retinal Maxwell centroids, leading to confusion between mirror images, and stationary blinking light sources are cumbersome for practical use.

Innovation Solution

A portable ophthalmic device with a blinking illuminating element, including a frame, light sources, and optional color filters, that emits light at a predetermined frequency to reduce dyslexia effects, featuring a wearable design with optional automatic activation and adjustable light spectrum.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a stationary blinking light source is used to reduce dyslexia effects, then reading skills improve through asymmetry correction, but the device becomes bulky and difficult to move

Engineering Contradiction:

Improvedyslexia reduction effectivenessVSAvoidportability and ease of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines the blinking illuminating element with an ophthalmic device (glasses frame), merging the therapeutic light source with a wearable accessory. This integration allows the device to remain portable and easy to operate while maintaining the dyslexia reduction effectiveness through controlled blinking light emission.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the bulky mechanical stationary light source with a compact LED-based illuminating element that can be integrated into the ophthalmic device. This substitution enables portability while maintaining the therapeutic blinking light function for dyslexia reduction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If colored filters are provided on ophthalmic lenses to help dyslexic wearers, then reading skills improve, but the device does not effectively address retinal Maxwell centroid asymmetry

Engineering Contradiction:

Improvereading skill improvementVSAvoidfailure to correct mirror image confusion

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent employs periodic blinking action of the illuminating element at specific frequencies to stimulate the retinal Maxwell centroids. This periodic illumination creates temporal asymmetry that addresses the spatial asymmetry deficit in dyslexic patients, effectively correcting mirror image confusion while improving reading skills.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent changes the temporal parameter of light illumination by introducing controlled blinking at specific frequencies. This parameter change transforms the static colored filter approach into a dynamic illumination system that actively addresses retinal asymmetry through temporal modulation of light exposure.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If a laboratory power controller is used to provide blinking light, then reading skills improve, but the device becomes stationary and difficult to use regularly

Engineering Contradiction:

Improvereading skill improvementVSAvoidportability and practical usability

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into the ophthalmic device: correction lenses, blinking illuminating element, and power source all in one wearable unit. This multi-functional integration replaces the separate laboratory controller setup, enabling regular practical use while maintaining therapeutic effectiveness.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The ophthalmic device is designed to be self-contained with integrated power sources and control mechanisms, allowing the user to independently activate and use the blinking illuminating element without requiring external laboratory equipment or complex setup procedures.

Inventive Principle:

Principle #25Self-service
