Skin Tag Cryogenic Tips for Orientation-Independent Base Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tweezers devices for applying cryogenic matter to skin tags are less reliable when held at different orientations, obscuring the skin tag and reducing certainty of applying cryogenic matter to the base, and lack visual and tactile indications for precise application.
Innovation Solution
A tip with a thermally conductive material having a lip extending around the perimeter, ensuring contact with the base of the skin tag regardless of orientation, and providing a tactile sensation for assured treatment, integrated into a tweezers device with insulated and absorbent elements for controlled application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing tweezers devices are held at different orientations relative to the skin, then the device can be applied more flexibly, but the reliability of applying cryogenic matter to the base of the skin tag decreases
Solution Approach 1:
The tip is designed with an asymmetric structure where the absorbent application element is offset from the central axis of the device. This offset positioning ensures that the absorbent element consistently contacts the base of the skin tag regardless of the device's orientation relative to the skin surface, thereby maintaining reliable application while allowing orientation flexibility.
Solution Approach 2:
The invention introduces a new spatial dimension by extending the absorbent application element laterally beyond the device's central axis. This dimensional extension creates a broader contact zone that intersects with the base of the skin tag across multiple orientations, ensuring reliable cryogenic matter application while maintaining device adaptability.
2Productivity
If existing tweezers devices are used to apply cryogenic matter to skin tags, then treatment can be performed, but the user cannot visually or tactilely confirm that the base of the skin tag is being treated
Solution Approach 1:
The tip incorporates tactile feedback through its structural design, where the user can feel the contact between the absorbent application element and the base of the skin tag. This tactile feedback provides real-time confirmation that the cryogenic matter is being applied to the correct location, eliminating the loss of application information while maintaining treatment delivery.
3Productivity
If existing tweezers devices are applied to skin tags, then cryogenic matter can be delivered, but the skin tag is obscured from view
Solution Approach 1:
The device is segmented into distinct functional zones: the tip portion that contacts the skin tag for cryogenic matter delivery, and the handle portion that remains visible to the user. This segmentation allows the tip to be positioned at the base of the skin tag for effective treatment while keeping the upper portion of the skin tag visible, resolving the contradiction between delivery effectiveness and visual monitoring.
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 solution ensures high certainty of applying cryogenic matter to the base of the skin tag, regardless of device orientation, with tactile feedback and effective freezing of both the base and distal portions, protecting collateral skin.
