Innovation Solution

A method that analyzes a person's images to determine oculomotor parameters and context data, allowing for the assessment of postural and visual behavior in real-life conditions, enabling the adaptation of optical functions and detection of lens utilization anomalies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If standard environment measurements are used for optical lens delivery, then the process is simple and quick, but the customization of optical designs is insufficient

Engineering Contradiction:
Improvesimplicity of optical lens delivery processVSAvoidcustomization of optical designs
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent changes the parameters of measurement by transitioning from standard environment measurements to real-life condition measurements. Image capture devices record oculomotor parameters (eye movements, head position) in various real-life contexts, and these parameter variations enable customized optical design calculations that adapt to individual user behaviors and environments

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces image capture devices and processing software as intermediaries between the user and the optical lens delivery process. These intermediaries capture and analyze real-life behavioral data, which then informs the customization of optical designs without requiring complex direct measurement equipment in the optical lab

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If more personalized data is collected for optical design customization, then the optical function adaptation improves, but the complexity of data collection and analysis increases

Engineering Contradiction:
Improveoptical function customizationVSAvoidcomplexity of data collection system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses image capture devices that automatically record oculomotor parameters in real-life conditions without requiring active user participation or specialized user equipment. Users simply go about their normal activities while the system passively collects data, eliminating the need for complex user-operated measurement devices

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent performs preliminary data collection by capturing images and analyzing oculomotor parameters before the optical lens manufacturing process. This advance collection of behavioral data allows the optical design to be pre-customized based on real-life patterns, simplifying the subsequent manufacturing process

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If real-life condition measurements are used instead of standard environment measurements, then the accuracy of postural and visual behavior determination improves, but the measurement process becomes more complex

Engineering Contradiction:
Improveaccuracy of postural and visual behavior dataVSAvoidcomplexity of measurement process
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical measurement equipment with image capture devices and computational analysis. Instead of using specialized optometric instruments to measure eye movements and head position, the system uses standard imaging technology combined with image processing algorithms to extract oculomotor parameters from photographs and videos

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