Solution Overview

Problem

Current treatments for chronic pruritus and large-scale skin irritations, such as those caused by cnidarians, are ineffective and often lead to side effects, with existing devices unable to address the issue of itching over extensive areas safely and effectively.

Innovation Solution

A device with a treatment area of at least 6 cm², utilizing a heating plate system that regulates temperature between 42°C and 53°C for a controlled 4-6 second treatment phase, activating C fibers and TRPV1/2 receptors to alleviate itching without causing pain or burns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If a heating device with small treatment area (less than 6 cm²) is used, then the device can be compact and easy to handle, but it cannot effectively treat large areas of skin affected by pruritus

Engineering Contradiction:
Improvetreatment areaVSAvoiddevice structure
Core Design Contradiction:
Area of moving objectVSDevice complexity

Solution Approach 1:

The heating device is divided into multiple independent heating zones (first heating zone and second heating zone) that can be independently controlled. This segmentation allows the device to cover a larger treatment area (at least 6 cm²) while maintaining manageable complexity through modular design, where each zone can be regulated separately to treat different areas of pruritus-affected skin.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heating device is designed to perform multiple functions: it can treat both small and large areas of skin, accommodate different pruritus conditions (insect bites, chronic pruritus, dermatitis), and provide controlled thermal therapy across varying treatment areas. The multi-zone heating capability enables the same device to adapt to diverse treatment requirements without requiring multiple specialized devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If the treatment temperature is increased to quickly relieve itching, then the relief effect is enhanced, but the risk of causing pain or skin damage increases

Engineering Contradiction:
Improveitching relief effectivenessVSAvoidskin damage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The heating device employs dynamic temperature control with multiple adjustable heating zones that can be independently regulated. The control unit allows real-time adjustment of temperature and heating duration based on the specific treatment needs and patient tolerance, enabling the system to optimize between effective itching relief and skin safety rather than using a fixed high-temperature setting.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device applies thermal therapy in controlled periodic cycles rather than continuous high-temperature exposure. The treatment protocol involves alternating heating phases with cooling intervals, allowing the skin to receive therapeutic heat doses while preventing cumulative thermal damage. This periodic application enhances itching relief effectiveness while maintaining skin integrity.

Inventive Principle:
Principle #19Periodic action

3Ease of operation

If medication is used to treat pruritus, then itching symptoms can be relieved, but side effects and drug interactions occur

Engineering Contradiction:
Improvetreatment simplicityVSAvoidside effects
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention replaces pharmacological treatment with a physical therapy approach using controlled thermal energy. Instead of administering medications that carry risks of side effects and interactions, the device uses precisely controlled heating zones to deliver thermal therapy that relieves itching through physiological mechanisms, eliminating drug-related harmful factors while maintaining treatment simplicity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
