Solution Overview

Problem

Existing cryotherapy methods often result in inconsistent skin pigmentation changes, either hypopigmentation or hyperpigmentation, due to varying freezing conditions, and there is a need for improved systems and methods to achieve consistent and reliable skin freezing for cosmetic purposes.

Innovation Solution

A dermatological treatment system with a handpiece featuring a cold plate and a suspension assembly tip that allows for controlled delivery of cooling treatments, including smooth and textured tips, and a GUI-guided method for precise temperature control and application, using a chiller and cooler to maintain desired skin temperatures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional cryoprobes are used for skin freezing, then tissue freezing effect is achieved, but severe freezing damage and cellular damage occur

Engineering Contradiction:

Improveskin freezing temperatureVSAvoidcellular damage

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by precisely controlling temperature, freezing duration, and thawing rate parameters. The system maintains skin surface temperature between -40°C to +40°C with ±1°C precision, using controlled freezing durations (e.g., 60-120 seconds) and controlled thawing rates (e.g., 10-30°C per minute) to achieve therapeutic effects while avoiding cellular damage that occurs with conventional uncontrolled cryotherapy

Inventive Principle:

Principle #35Parameter changes

2Reliability

If conventional cryosurgery is used for pigmentation treatment, then hypopigmentation effect is achieved, but inconsistent and unpredictable pigmentation results occur

Engineering Contradiction:

Improvepigmentation treatment consistencyVSAvoidskin pigmentation uniformity

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent implements feedback control through real-time temperature monitoring using thermocouples or thermal cameras, with the system continuously adjusting cooling power to maintain predetermined temperature profiles. The controller receives temperature feedback and dynamically modulates the cooling rate to ensure consistent melanocyte destruction while preserving surrounding tissue, achieving uniform pigmentation results

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system applies dynamics by using adjustable and programmable freezing parameters that can be customized for different treatment areas and pigmentation conditions. The freezing duration, temperature profile, and thawing rate are dynamically adjusted based on real-time monitoring and pre-programmed protocols, enabling consistent reproduction of optimal treatment conditions

Inventive Principle:

Principle #15Dynamics

3Reliability

If skin freezing is performed for cosmetic purposes, then skin lightening effect is achieved, but long-lasting or permanent hypopigmentation occurs

Engineering Contradiction:

Improvecosmetic treatment predictabilityVSAvoidhypopigmentation duration

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent applies partial action by using controlled mild freezing rather than severe freezing. The system maintains temperatures in the range of -40°C to +40°C with precise control, applying just enough cooling to affect melanocyte function temporarily without causing complete cellular destruction. This partial action achieves cosmetic lightening effects while avoiding permanent hypopigmentation

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The treatment protocol employs periodic action through multiple short-duration freezing cycles separated by thawing periods. The system applies freezing for predetermined intervals (e.g., 60-120 seconds) followed by controlled thawing, repeating cycles as needed to achieve cumulative cosmetic effects while allowing tissue recovery between cycles, thereby avoiding permanent damage

Inventive Principle:

Principle #19Periodic action

AI summary

Dermatological treatments and systems employing cooling, topicals, and/or abrasion are disclosed herein. The system can include a cold plate and a suspension assembly tip. The suspension assembly tip can be selectively coupleable to the cold plate. The suspension assembly tip can include a suspension tip and a suspension. The suspension tip can include a contact surface that can be contacted onto a patient's skin to provide a treatment. The suspension can couple to both the cold plate and to the suspension tip. The suspension can be thermally conductive so as to closely thermally couple the suspension tip to the cold plate, or the suspension tip can have a low thermal conductivity so as to not closely thermally coupled the suspension tip to the cold plate.
