Solution Overview

Problem

Existing treatments for meibomian gland dysfunction and dry eye syndrome are disruptive, obtrusive, and do not effectively leverage the patient's natural blinking mechanism for treatment, necessitating a non-invasive and non-disruptive method for disease prognosis and treatment.

Innovation Solution

A treatment system comprising flexible heating strips secured to the eyelids using ear attachments, which apply heat or other therapies while allowing natural blinking, combined with a controller and image capture device for monitoring treatment progression and disease severity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments for meibomian gland dysfunction are applied, then treatment effectiveness is achieved, but patient disruption and obtrusiveness increase

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidpatient disruption
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The treatment system leverages the patient's own natural blinking mechanism to deliver therapy. The heating strip applies thermal energy to the meibomian glands, and the patient's natural blinks provide the mechanical expression force needed to clear the glands, eliminating the need for disruptive manual manipulation or procedural interventions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The treatment utilizes the periodic nature of natural blinking (occurring automatically every few seconds) to deliver repeated therapeutic effects. Each blink provides a mechanical expression action that complements the thermal therapy, creating a continuous treatment cycle without requiring patient intervention or disrupting daily activities.

Inventive Principle:
Principle #19Periodic action

2Loss of information

If existing treatment methods are used, then disease prognosis is obtained, but measurement and monitoring precision are insufficient

Engineering Contradiction:
Improvedisease prognosis capabilityVSAvoidmonitoring precision
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The system incorporates an image capture device that takes photographs of the patient's eyes at regular intervals during treatment. These images are transmitted to a remote server that analyzes disease severity and compares it against baseline measurements, providing real-time feedback on treatment effectiveness and enabling precise monitoring of disease progression or improvement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

A remote server acts as an intermediary between the patient's treatment system and the analysis infrastructure. The server receives images from the portable device, performs sophisticated disease severity analysis using external computational resources, and returns detailed prognosis information, enabling precise monitoring without requiring complex local processing equipment.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems for eye treatment are disclosed where the system generally includes a housing defining a receiving channel and a first flexible support extending from the housing and having a first heating strip at a distal end of the first flexible support, wherein a proximal portion of the first flexible support defines a curved or bent portion which orients the first heating strip to extend in a first direction. The system also includes a second flexible support extending from the housing and having a second heating strip at a distal end of the second flexible support, wherein a proximal portion of the second flexible support defines a curved or bent portion which orients the second heating strip in a second direction. The flexible supports may further define a distal curved or bent portion proximal to the heating strips such that the heating strips are positioned to extend away from one another.
