Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing models for training medical professionals in eye surgery, such as animal eyes, require refrigeration and special handling, posing regulatory and logistical challenges.

Innovation Solution

A model human eye with a hemispherical shape, featuring a transparent cornea and opaque sclera, and a lenticular bag that mimics the anatomy and physiology of the human eye, eliminating the need for refrigeration and simplifying handling procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If animal eyes are used for training, then realistic anatomical practice is achieved, but refrigeration and special handling procedures are required

Engineering Contradiction:

Improveanatomical realismVSAvoidhandling procedures

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent creates an artificial eye model that copies the essential anatomical structures of a real human eye, including the cornea, iris, lens, and vitreous humor, using synthetic materials. This allows medical students to practice surgical techniques on a realistic model without using actual animal or human eyes, thereby eliminating refrigeration and special handling requirements while maintaining training effectiveness

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If animal eyes are used for training, then surgical practice is enabled, but compliance with Blood Born Pathogens Standard is required

Engineering Contradiction:

Improvetraining capabilityVSAvoidregulatory compliance

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The artificial eye model is designed as a disposable training tool made from synthetic materials that can be manufactured at low cost. After use, the model can be discarded without requiring complex disposal procedures or regulatory compliance related to blood-borne pathogens, as it contains no biological materials

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If animal eyes are refrigerated, then preservation is achieved, but loss of time for preparation and disposal is incurred

Engineering Contradiction:

ImprovepreservationVSAvoidpreparation and disposal time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The artificial eye model is pre-manufactured with realistic anatomical structures and can be stored at room temperature without refrigeration. This eliminates the time required for refrigeration preparation before training sessions and simplifies post-use disposal, as no special preservation or disposal procedures are needed

Inventive Principle:

Principle #10Preliminary action

AI summary

A model human eye is disclosed. The model human eye comprises a extended hemispherical-shaped assembly comprising a center point, an open end defined by a first continuous distal end, a cornea portion symmetrically disposed around the center point, and a sclera portion disposed between the cornea portion and the first continuous distal end. The extended hemispherical-shaped assembly comprises an integral molding. The model human eye further comprises a lenticular bag disposed within the extended hemispherical-shaped assembly. The model human eye further comprises a base comprising a bottom and one or more walls attached to that bottom and extending outwardly therefrom, where the one or more walls comprise a second continuous distal end. The first continuous distal end is attached to the second continuous distal end to define an enclosed space. The lenticular bag separates the enclosed space into an anterior chamber and a posterior chamber.
