Solution Overview

Problem

Existing microneedling devices often hinder the skin's natural vibration during puncturing, leading to inefficient and potentially painful application of microneedles.

Innovation Solution

A hand-held microneedling device with a microneedling puncturing tool that moves back and forth between exposed positions, allowing the skin to vibrate freely and facilitating efficient, painless puncturing by arranging puncturing needles entirely outside the housing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the microneedling puncturing tool is moved back and forth with the aid of an electric motor, then the puncturing efficiency is improved, but the housing edge surrounding the housing opening hinders the skin's natural vibration during puncturing

Engineering Contradiction:

Improvepuncturing efficiencyVSAvoidskin vibration hindrance

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The puncturing needles are extracted from the housing structure and arranged entirely outside the housing in the front and rear working positions. This allows the skin to vibrate freely during puncturing without being hindered by the housing edge, while the electric motor continues to provide automated back-and-forth movement for efficient puncturing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of having the housing surround and constrain the needle plate during operation, the design inverts this arrangement by positioning the needle plate and puncturing needles entirely outside the housing. This inversion eliminates the harmful constraint on skin vibration while maintaining the beneficial automated movement provided by the electric motor.

Inventive Principle:

Principle #13The other way round (Inversion)

2Stability of the object's composition

If the puncturing needles are arranged on a needle plate surrounded by a front housing portion, then the device structure is stable, but the skin surface cannot vibrate freely during puncturing

Engineering Contradiction:

Improvedevice structure stabilityVSAvoidskin vibration freedom

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The needle plate with puncturing needles is extracted from the housing structure and positioned entirely outside the housing in both front and rear working positions. This extraction allows the skin to vibrate freely during operation while the housing maintains its structural stability for supporting the electric motor and drive mechanisms.

Inventive Principle:

Principle #2Taking out (Extraction)

3Productivity

If the microneedling puncturing tool is moved back and forth between extended and retracted positions, then the puncturing coverage is improved, but the complexity of the device increases

Engineering Contradiction:

Improvepuncturing coverageVSAvoiddevice structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The housing portions that move together with the microneedling puncturing tool are merged into a single integrated assembly. This combining reduces the number of separate components and simplifies the overall device structure while still achieving the beneficial back-and-forth movement between extended and retracted positions for improved puncturing coverage.

Inventive Principle:

Principle #5Merging (Combining)
