Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current treatments for chalazion, such as warm compresses and antibiotic/cortisone ointments, are often ineffective in reducing irritation, redness, and swelling, and can be inconvenient and prone to infectious complications.

Innovation Solution

A topical composition comprising castor oil, refined coconut oil, and vaseline, combined with a massaging motion using a roll-on application device, to reduce irritation, redness, and swelling of the eyelid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If warm compresses are applied several times a day, then the chalazion may be reabsorbed, but the treatment is inconvenient and time-consuming

Engineering Contradiction:

Improveeffectiveness of chalazion treatmentVSAvoidconvenience of treatment application

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The treatment device pre-heats the compress material before application to the eyelid, eliminating the need for the user to prepare hot water or heat sources. The heating element is integrated into the device and automatically activates, performing the heating action in advance and eliminating the inconvenience of preparing warm compresses multiple times throughout the day.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If antibiotic and cortisone ointment is applied manually with a finger, then the chalazion area is treated, but infectious complications may occur and precise dose control is difficult

Engineering Contradiction:

Improveeffectiveness of ointment treatmentVSAvoidinfectious complications and contamination risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device uses a disposable applicator tip as an intermediary between the ointment reservoir and the eyelid. This intermediary prevents direct contact between the user's finger and the chalazion area, eliminating the risk of infectious complications from contaminated hands. The applicator tip is discarded after use, ensuring no cross-contamination occurs.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device replaces manual finger application with a mechanical dispensing system that uses a rotating wheel mechanism to precisely control the amount of ointment applied. This mechanical system ensures consistent, precise dosing while eliminating the variability and contamination risks associated with manual application.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If manual ointment application is used, then treatment can be applied, but precise control of deposited dose and targeted area is not achieved

Engineering Contradiction:

Improvesimplicity of applicationVSAvoidprecision of dose and area control

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The device replaces imprecise manual application with a mechanical dispensing system featuring a rotating wheel with controlled rotation. The wheel mechanism, combined with a calibrated applicator tip, delivers a precise and consistent amount of ointment to the targeted area. The mechanical system ensures reproducible dosing while maintaining ease of operation through simple activation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
