Solution Overview

Problem

Current medical aesthetic devices often cause uncontrolled collagen stimulation leading to scar tissue and keloids, and existing technologies lack effective methods for safe, controlled micro-injury to remodel scar tissue and improve skin elasticity.

Innovation Solution

A collagen stimulating device with a single-handed operable needle module that uses X-shaped needles to penetrate the skin safely, reducing cross-contamination and damage, featuring a sensing system to determine needle position and modulate depth, frequency, and power of needle movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional needles are used for skin penetration, then collagen stimulation is achieved, but uncontrolled collagen over-stimulation occurs leading to scar tissue and keloids

Engineering Contradiction:
Improvecontrolled collagen stimulationVSAvoidscar tissue and keloid formation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The needle tip is designed with an asymmetric configuration where one side has a sharp edge for effective skin penetration and collagen stimulation, while the other side is blunt to minimize damage and prevent uncontrolled collagen over-stimulation. This local differentiation of properties allows controlled micro-injury that stimulates collagen production without causing scar tissue or keloid formation.

Inventive Principle:
Principle #3Local quality

2Reliability

If needle depth is increased to reach dermis, then collagen remodeling is effective, but damage to surrounding tissue increases

Engineering Contradiction:
Improvecollagen remodeling effectivenessVSAvoidtissue damage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The needle incorporates a sharp edge on one side of the tip for effective penetration and collagen stimulation at the desired depth, while the opposite blunt side limits the extent of tissue disruption. This asymmetric design ensures that when the needle reaches the dermis for effective collagen remodeling, it minimizes damage to surrounding tissue by preventing excessive lateral injury.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If needle module is designed for single-handed operation, then ease of use during procedure is improved, but mechanism for safe loading and unloading becomes more complex

Engineering Contradiction:
Improvesingle-handed operationVSAvoidloading and unloading mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The needle module incorporates a snap-fit attachment mechanism with a release button that allows the operator to load and unload needle cartridges using only one hand. The self-contained design with integrated release functionality eliminates the need for two-handed operation, making the device user-friendly during procedures while maintaining safe needle handling through the automated snap-fit engagement and disengagement system.

Inventive Principle:
Principle #25Self-service

AI summary

Device for safely and precisely causing micro-injuries to the dermis to stimulate collagen production a skim remodeling. Specifically, needles on the device pierce the epidermis and basal cell layer into the dermis. The device incorporates safety features for the operator to be able to operate the device with one hand while keeping the other had free during procedures. Additionally, the device incorporates single use safety controls to help prevent cross contamination between patients.
