Solution Overview

Problem

Current treatments for eye disorders, such as presbyopia, are limited in effectiveness and often require invasive surgical procedures or short-term pharmacological methods with adverse side effects, failing to fully correct vision issues.

Innovation Solution

A modulated laser treatment system that scans the eye to create a mapping, delivering a laser illumination light beam based on the mapping to specific locations, using patterns and power settings tailored to the individual eye's anatomy and color, allowing for precise treatment of the iris and cornea.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pharmacological treatment is used to constrict pupils, then pupil constriction is achieved, but efficacy decreases over time and adverse side effects occur

Engineering Contradiction:

Improvetreatment efficacyVSAvoidtreatment duration

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent replaces pharmacological treatment (chemical system) with laser treatment (optical/physical system) to constrict pupils. The laser applies controlled thermal energy to the iris tissue to induce permanent constriction, eliminating the need for ongoing medication and avoiding pharmacological side effects while providing long-lasting correction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state of iris tissue through controlled laser heating, transforming the tissue structure to create permanent pupillary constriction. By adjusting laser parameters (energy, duration, wavelength), the treatment achieves durable structural modification rather than temporary pharmacological effect.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If corrective surgical procedures are used to alter focal distance, then nearsightedness correction is achieved, but distance vision is reduced and effects are not fully corrective

Engineering Contradiction:

Improvevision correction precisionVSAvoiddistance vision reduction

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies laser treatment locally to specific regions of the iris to induce pupillary constriction, rather than altering the overall focal distance of the eye. This localized approach corrects vision by reducing the effective aperture, which improves depth of focus and reduces optical aberrations without compromising distance vision capability.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of correcting vision by altering the lens focal distance (traditional approach), the patent inverts the approach by using pupillary constriction to achieve vision correction. This alternative mechanism corrects refractive errors through aperture control rather than focal length modification, preserving distance vision while improving near vision.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If uniform laser treatment is applied to the eye, then treatment simplicity is maintained, but individual eye anatomy and color variations are not accounted for

Engineering Contradiction:

Improvetreatment application simplicityVSAvoideye-specific customization

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent performs preliminary scanning and mapping of the patient's eye anatomy and iris characteristics before applying laser treatment. This pre-assessment allows the system to customize treatment parameters (energy, pattern, duration) based on individual eye properties, ensuring optimal results while maintaining automated treatment application.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs dynamic treatment parameters that adapt to real-time feedback from eye scanning and mapping. The laser treatment pattern and energy delivery are adjusted based on measured iris thickness, pigmentation, and anatomical variations, allowing the system to accommodate individual differences while maintaining automated operation.

Inventive Principle:

Principle #15Dynamics
