Solution Overview

Problem

Traditional methods for assessing visual function require expensive optical equipment and are time-consuming, limiting frequent monitoring of changes in visual health without the need for periodic complete diagnoses.

Innovation Solution

A self-guided computerized vision measurement system using a computer and mobile device for users to assess their own vision attributes, analyzing acuity, sphere, cylinder, and axis through audio prompts and camera assistance, with raw data interpreted by a licensed physician.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional optical equipment is used for vision assessment, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improvevision assessment accuracyVSAvoidoptical equipment complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses computer-generated virtual optotypes that replicate traditional eye chart symbols through digital display rather than physical optical equipment. The system creates virtual Landolt C rings and other vision test stimuli on a computer screen, eliminating the need for complex optical instruments while maintaining measurement capability.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces mechanical optical measurement systems with computer-based visual presentation and response capture. Instead of using physical optometers or ophthalmoscopes, the system uses software-controlled display of visual patterns and digital capture of user responses to determine vision parameters.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If traditional diagnostic methods are used, then measurement precision is improved, but loss of time increases due to infrequent monitoring

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidtime between diagnoses
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent enables individuals to perform self-assessment of vision function using computer-based tools without requiring visits to optometrists or ophthalmologists. Users can independently complete vision tests, track changes over time, and monitor their own visual health, eliminating the need for periodic professional diagnoses while maintaining accurate self-monitoring.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent allows users to perform preliminary vision assessments at home before seeking professional care. The system provides tools for initial screening and monitoring that can be used continuously, enabling early detection of vision changes and reducing the waiting time between professional diagnostic visits.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If expensive optical equipment is used, then measurement precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvevision testing accuracyVSAvoidaccessibility for users
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent creates simplified digital copies of traditional vision test equipment through computer software. Instead of requiring users to operate complex optical instruments, the system presents simplified computer-generated visual patterns and captures responses through standard input methods, making vision assessment accessible to laypeople while maintaining diagnostic capability.

Inventive Principle:
Principle #26Copying
