Concave Applicator Tip for Precise Skin Lesion Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatments for skin lesions, such as warts, face challenges in precisely applying refrigerants due to the irregular surface of the lesions, leading to incomplete coverage and application to healthy tissue.
Innovation Solution
A device comprising a container, applicator tube, and an applicator tip made from a material that absorbs the treatment agent, with a concave surface to ensure effective application to the lesion while minimizing contact with healthy skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a refrigerant is applied to a skin lesion with an irregular surface, then the treatment agent can reach the lesion, but the application is imprecise leading to incomplete coverage and application to healthy tissue
Solution Approach 1:
The applicator tip features a concave surface that conforms to the irregular shape of skin lesions, allowing precise application of the refrigerant treatment agent. The curved geometry enables the tip to envelop the lesion surface, ensuring complete coverage while preventing contact with surrounding healthy tissue, thus resolving the contradiction between application precision and treatment agent distribution.
2Ease of manufacture
If a flat applicator tip is used, then the device structure is simple, but it cannot effectively conform to the irregular surface of the skin lesion
Solution Approach 1:
The applicator tip is designed with a concave surface that mirrors the irregular topography of skin lesions. This curved geometry allows the tip to adaptively conform to various lesion shapes and sizes, ensuring reliable and complete coverage. The manufacturing process incorporates this curvature through molding techniques, balancing structural complexity with production feasibility.
3Quantity of substance
If the applicator tip contacts the irregular lesion surface, then complete coverage is achieved, but compression of the lesion occurs which may affect treatment efficacy
Solution Approach 1:
The applicator tip is constructed from a flexible, compressible material that can deform to match the irregular surface of the skin lesion. This flexibility allows the tip to envelop the lesion contours for complete treatment agent coverage while distributing contact pressure evenly, minimizing localized compression that could affect treatment efficacy. The material properties enable adaptive conforming without excessive force application.
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
The concave applicator tip envelops the skin lesion effectively, applying a higher amount of treatment agent to the lesion while reducing application to healthy skin, making the device easier to use and improving overall coverage.
Implementation Method 1
the applicator tip is made from a material that absorbs a skin lesion treatment agent
Implementation Method 2
at least part of the exposed surface of the applicator tip is concave
