Solution Overview

Problem

Current optical coherence tomography (OCT) devices are not fast enough to capture useful measurements of eye tissue biomechanics, limiting the ability to diagnose and treat eye diseases such as glaucoma, Keratoconus, and ectasia.

Innovation Solution

A system and method utilizing an OCT device in conjunction with a computer to measure biomechanics in real-time at multiple eye-tissue locations. The system simultaneously emits multiple beams from the OCT device to various measurement locations on the eye tissue in response to a stimulus, allowing for the collection of OCT data and measurement of tissue responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional OCT devices are used to measure eye tissue biomechanics, then measurement accuracy can be maintained, but measurement speed is too slow to capture real-time tissue responses

Engineering Contradiction:
Improvemeasurement speedVSAvoidtime to capture tissue response
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent divides the measurement process into multiple parallel OCT beam paths that simultaneously measure different locations on the eye tissue. By segmenting the measurement task across multiple beams rather than sequentially scanning, the system captures real-time biomechanical responses at multiple points concurrently, resolving the contradiction between measurement speed and time loss.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If multiple measurement locations are monitored simultaneously, then comprehensive biomechanical data is obtained, but system complexity increases

Engineering Contradiction:
Improvebiomechanical measurement comprehensivenessVSAvoidOCT system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple OCT beam paths into a unified measurement system that simultaneously monitors multiple locations. By merging the functionality of multiple sequential measurements into a single parallel system, comprehensive biomechanical data is obtained without proportionally increasing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)
