Precision Skin Cooling Temperature Control for Itch Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin disease treatments that involve cooling can induce nitric oxide production, leading to serotonin-induced itchiness and pose safety risks due to potential necrosis from excessive cooling, making it difficult to find an appropriate cooling temperature for therapeutic effect.
Innovation Solution
A method using precision cooling technology to cool the skin surface to a target temperature between −5° C. to 5° C. for a specific time, maintaining a standard deviation of no more than 3° C., to reduce biomarker molecules associated with skin conditions like atopic dermatitis and acne.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cooling is applied to alleviate skin disease symptoms, then pain relief is achieved, but skin necrosis and increased nitric oxide production occur
Solution Approach 1:
The patent applies parameter changes by precisely controlling cooling temperature within a specific range (−5°C to 5°C) and duration (1-30 seconds) to achieve therapeutic effects while avoiding harmful outcomes. This quantitative parameter optimization resolves the contradiction between pain relief and prevention of skin necrosis and nitric oxide production.
Solution Approach 2:
The patent employs feedback control through temperature sensors and control modules that continuously monitor skin temperature during cooling treatment. This real-time feedback ensures the skin temperature remains within the safe therapeutic range, preventing both insufficient pain relief and excessive cooling that would cause necrosis.
2Reliability
If cooling temperature is reduced to increase therapeutic effect, then symptom relief improves, but safety decreases due to necrosis risk
Solution Approach 1:
The patent establishes specific parameter ranges (temperature: −5°C to 5°C, time: 1-30 seconds) that optimize therapeutic effect while maintaining safety. These parameter changes define the precise cooling conditions needed to achieve symptom relief without causing skin necrosis.
Solution Approach 2:
The patent implements prior cushioning by pre-setting safe operating parameters and control systems before treatment begins. The temperature control module and sensor system are prepared in advance to prevent excessive cooling, cushioning against the risk of necrosis before it can occur.
3Reliability
If precise temperature control is implemented, then treatment safety improves, but device complexity increases
Solution Approach 1:
The patent uses feedback control with temperature sensors and control modules to maintain skin temperature within the safe range. This automated feedback system improves treatment safety by continuously monitoring and adjusting cooling parameters, reducing the need for complex manual control mechanisms.
Solution Approach 2:
The temperature control system operates autonomously using self-service principles, where the control module automatically adjusts cooling based on sensor feedback without requiring constant manual intervention. This reduces operational complexity while maintaining high treatment safety.
