Solution Overview

Problem

Existing instruments are inadequate for safely and effectively removing molluscum contagiosum, a common skin condition, and specific tools are needed to address this need.

Innovation Solution

A device with two cutting edges, each having distinct configurations, is designed to remove molluscum contagiosum, featuring a first cutting edge with a slope and a second cutting edge with parallel side surfaces, allowing for axial gliding and lesion capture, along with a grip portion for user control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing instruments are used to remove molluscum contagiosum, then the treatment can be performed, but the safety and effectiveness are inadequate

Engineering Contradiction:

Improvesafety and effectivenessVSAvoidsuitability for molluscum contagiosum

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device incorporates cutting edges with specific geometric configurations (first cutting edge with slope, second cutting edge with parallel side surfaces) that are locally optimized for the specific task of removing molluscum contagiosum lesions, providing tailored cutting action for this particular skin condition

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device features multiple cutting edges (first and second cutting edges) with different configurations, allowing selective use of appropriate cutting edges for different lesion types or removal techniques, enhancing adaptability while maintaining safety and effectiveness

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If the cutting edge moves laterally across the skin, then precise cutting is achieved, but skin contact area increases potential harm

Engineering Contradiction:

Improveprecise cuttingVSAvoidskin contact harm

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The cutting edges are designed with curved or rounded profiles rather than sharp angular edges, allowing the blade to glide laterally across the skin surface while minimizing penetration depth and reducing the risk of excessive skin damage during the cutting motion

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The device structure includes features that limit the maximum depth and lateral extent of skin contact before harmful effects can occur, providing built-in protection against excessive tissue damage during the removal process

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
