Solution Overview

Problem

The increasing concern of cross-contamination in healthcare settings, particularly during automated diagnostic procedures, due to reduced personnel availability for cleaning equipment, necessitates improved hygiene measures.

Innovation Solution

An inflatable mask with optically transparent sections and a concaved surface that conforms to the patient's face, forming air-tight ocular cavities to maintain cleanliness and stability during medical examinations, and can interface with medical devices like OCT systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an inflatable mask with ocular cavities is used to create a hygienic barrier, then cross-contamination is prevented and hygiene is improved, but device complexity increases due to the need for inflation mechanisms and sealed cavities

Engineering Contradiction:
ImprovehygieneVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mask is divided into distinct functional segments: an inflatable member that forms sealed cavities around each eye separately, allowing independent control and sealing of each ocular region. This segmentation enables effective hygienic isolation while maintaining manageable device complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inflatable mask acts as an intermediary barrier between the medical device and the patient's face, creating a disposable or cleanable interface that prevents direct contact and cross-contamination. The inflation mechanism enables this intermediary structure to adapt and seal effectively

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the inflatable member is inflated to conform to the patient's face, then patient comfort and seal integrity are improved, but the risk of discomfort or injury from excessive pressure increases

Engineering Contradiction:
Improvepatient comfortVSAvoidpressure-related harm
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The inflatable member employs dynamic pressure control, allowing the system to adjust inflation levels in real-time to match patient anatomy and comfort requirements. The pressure can be modulated during the examination procedure to maintain optimal sealing without causing discomfort or injury

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms to monitor inflation pressure and adjust accordingly, ensuring that the mask conforms to the patient's face adequately for sealing while preventing excessive pressure that could cause harm. This feedback loop maintains safety and comfort

Inventive Principle:
Principle #23Feedback

3Reliability

If the mask is designed to be disposable to ensure hygiene, then cross-contamination is eliminated, but loss of substance increases due to continuous consumption of masks

Engineering Contradiction:
ImprovehygieneVSAvoidmask consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The mask is designed as a disposable component that can be easily manufactured from inexpensive materials, making it economically viable to replace after each use. This disposable design ensures complete hygiene by eliminating cross-contamination risks while the low cost minimizes the impact of continuous consumption

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The system enables easy discarding of used masks and facilitates recovery or replacement with new ones. The modular design allows for efficient disposal and rapid replacement, minimizing downtime and ensuring continuous hygienic operation

Inventive Principle:
Principle #34Discarding and recovering

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

AI summary

A mask for performing an eye exam of a subject includes one or more optically transparent sections for transmitting an incident light beam therethrough and incident on the subject's eye. In some embodiments, the one or more optically transparent sections are coated with an anti-reflective coating configured to reduce reflection of the incident light beam by the one or more optically transparent sections. In some embodiments, the one or more optically transparent sections may have a portion thereof that is tilted with respect to the incident light beam when the mask is optically interfaced with the docking portion of an ophthalmic instrument, such that the incident light beam forms a finite angle of incidence with respect to the corresponding portion of the optically transparent sections.
