Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for integrating amniotic membranes with contact lenses are complex and invasive, leading to complications such as infection, discomfort, and delayed healing, necessitating a simpler and more stable attachment method.

Innovation Solution

The use of anchor points, slots, or ridges on the contact lens surface to secure amniotic membranes without adhesives, combined with materials like silicon hydrogel or collagen, and optional use of biological or synthetic glues, or a piggybacking configuration for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If suturing or adhesion materials are used to attach the amniotic membrane to the eye, then the membrane can be secured in place, but complications such as infection, discomfort, and delayed healing occur

Engineering Contradiction:

Improvemembrane attachment stabilityVSAvoidinfection and discomfort

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and eliminates the harmful adhesion materials and suturing components from the attachment system. By using a contact lens with integrated anchor points that mechanically secure the membrane through physical interlocking rather than chemical adhesion, the patent removes the source of infection and discomfort while maintaining attachment reliability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The contact lens acts as an intermediary device between the amniotic membrane and the ocular surface. The lens with its anchor points provides a safe intermediate structure that secures the membrane without requiring direct contact between the membrane and potentially harmful adhesion materials or sutures

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If complex processes or additional materials are used to combine amniotic membranes with contact lenses, then secure attachment can be achieved, but the effectiveness and comfort of the treatment are compromised

Engineering Contradiction:

Improveattachment securityVSAvoidintegration process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges the contact lens and amniotic membrane into a single integrated therapeutic device. The anchor points are built into the lens structure itself, eliminating the need for separate attachment materials or complex multi-step integration processes. This simplifies the device while maintaining secure attachment

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact lens serves multiple functions: it provides the therapeutic contact lens effect, delivers medication, and simultaneously acts as an anchoring system for the amniotic membrane through its integrated anchor points. This multi-functionality eliminates the need for additional specialized attachment components

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

This document describes various methods for attaching biological tissues, such as amniotic membranes, to contact lenses. The techniques include using anchor points on the lens surface, employing biological or synthetic glues, and utilizing a piggybacking method. The materials involved in these processes can include silicon hydrogel, collagen, or other hydrogel materials, which may be loaded with growth factors or pharmaceutical agents. Additionally, the piggybacking configuration is designed to degrade or be bioabsorbed over a period of 1-10 days on the ocular surface.
