Solution Overview

Problem

Dysfunctional meibomian glands often cause dry eyes and other medical issues, and existing treatments require professional intervention or are not user-friendly.

Innovation Solution

A self-administered meibomian gland roller system with a heated cylinder and handle, combined with an eye pad, applies mechanical pressure to express meibomian glands, using a temperature-controlled heating element and washable roller head, allowing users to safely treat meibomian gland obstructions at home.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a roller system is designed for self-administered meibomian gland treatment, then user convenience and accessibility are improved, but treatment effectiveness and safety may be compromised compared to professional intervention

Engineering Contradiction:

Improveuser convenienceVSAvoidtreatment effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The roller incorporates temperature control parameters to maintain optimal heating temperature for meibomian gland treatment, ensuring effective melting of obstructed secretions while preventing thermal damage to surrounding tissues. This parameter control enables safe self-administration while maintaining treatment effectiveness.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system includes temperature sensing and control mechanisms that provide feedback to maintain the roller at the correct treatment temperature. This feedback loop ensures consistent therapeutic effect and safety, bridging the gap between professional and home-based treatment reliability.

Inventive Principle:

Principle #23Feedback

2Productivity

If heating is applied to melt obstructed secretions, then gland expression effectiveness is improved, but risk of thermal damage to surrounding tissues increases

Engineering Contradiction:

Improvegland expression effectivenessVSAvoidthermal damage risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The heating element is controlled to maintain a specific temperature range that is sufficient to melt obstructed meibomian secretions but low enough to prevent thermal damage to the eyelid skin and surrounding tissues. This optimized temperature parameter achieves effective gland expression while minimizing harmful thermal effects.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The roller design incorporates thermal management features that prevent excessive heat buildup before it can cause tissue damage. The controlled heating system provides a cushioning effect against thermal injury while maintaining the therapeutic heat necessary for effective treatment.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Productivity

If the roller applies mechanical pressure to express glands, then treatment effectiveness is improved, but user comfort and safety may be reduced

Engineering Contradiction:

Improvetreatment effectivenessVSAvoiduser discomfort

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The roller is designed with specific pressure distribution characteristics that concentrate mechanical force on the meibomian gland area while distributing pressure away from sensitive surrounding tissues. This local quality optimization enables effective gland expression without causing user discomfort or tissue damage.

Inventive Principle:

Principle #3Local quality

AI summary

An eye treatment system can comprise a roller with a handle, a power source, control circuitry coupled to the power source, an axle, coupled to the handle, a heating element within the roller, a cylinder configured to rotate about the axle, a temperature sensor adjacent to a surface of the cylinder, with the temperature sensor spaced apart from the heating element, and one or more arms of the roller that couple a first end of the handle to the axle, wherein at least one of the one or more arms houses first wiring through which power is supplied from the power source to the heating element and houses second wiring connecting the temperature sensor to the control circuitry. The treatment system might also comprise an eye pad comprising a heat-retaining material and sized to be applied to an eyelid of a user when warmed. The eye pad could be gel-filled.
