Handheld Itch Blower With Infrared Distance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for skin itching, such as the Electronic Itch Stopper, are limited in their ability to effectively treat large areas, curved surfaces, and blistering skin, and often cause burns or worsen itching due to the difficulty in maintaining a precise temperature for scalding without burning.
Innovation Solution
The Itch Blower modifies a hair dryer to use hot air for heating, incorporating temperature and distance control mechanisms, such as adjustable sticks or infrared sensors, to deliver heat safely and effectively to large or curved areas, maintaining a narrow temperature range that scalds without burning, using a thermostat and sensors to regulate the heating duration and intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hair dryer is used to heat the skin for itching relief, then the itching can be cleared, but the skin may be scalded or burned due to loss of control
Solution Approach 1:
The patent incorporates temperature sensors and control circuits that continuously monitor the temperature of the heating element and adjust power delivery in real-time. This feedback mechanism ensures the temperature remains within the therapeutic range (40-50°C) to relieve itching while preventing scalding or burning.
Solution Approach 2:
The patent uses adjustable temperature settings and controlled air flow rates to optimize the heating parameters. By precisely controlling these parameters, the device delivers sufficient heat to clear itching while maintaining safety margins to avoid skin damage.
2Reliability
If the hair dryer is positioned close to the skin to deliver effective heat, then itching relief is achieved, but the user feels scalding and moves the device away
Solution Approach 1:
The patent introduces a controlled air flow system as an intermediary between the heating element and the skin. The air flow carrier delivers heat gently and uniformly across the skin surface, allowing the device to be positioned at optimal distances without causing uncomfortable scalding sensations that would make users move it away.
3Ease of operation
If the hair dryer is positioned far from the skin to avoid scalding, then user comfort is maintained, but the heating becomes insufficient and itching worsens
Solution Approach 1:
The patent uses high-velocity air flow to rapidly transport thermal energy from the heating element to the skin surface. This rushing air flow delivers concentrated heat over short distances, allowing the device to be positioned farther from the skin while maintaining effective heating for itching relief without causing discomfort.
4Area of stationary object
If heat is applied to large areas of skin, then comprehensive itching relief is achieved, but existing devices like the Itch Stopper cannot treat curved surfaces or blistering skin
Solution Approach 1:
The patent employs a pneumatic air flow system that can be directed along curved surfaces and adapted to various skin topologies. The adjustable air flow pattern and flexible positioning capabilities allow comprehensive coverage of large, curved, or blistering skin areas, overcoming the limitations of contact-based heating devices.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The Itch Blower provides a safe and effective solution for treating large and curved skin areas, including blistering skin, by maintaining a controlled temperature that scalds without burning, effectively addressing the limitations of existing treatments and improving patient comfort and safety.
Implementation Method 1
a heating element to heat the air to a high temperature
Implementation Method 2
a fan to move the hot air toward the skin
Implementation Method 3
a thermostat to regulate the heating element to maintain a controlled temperature range

AI summary
The Itch Blower is hand held, have a way to determine the distance from the skin. It blows hot air with the right temperature for eliminating the skin itching. Most importantly, it can sense the skin temperature remotely and shut off the heating automatically so to avoid burning. This will guarantee a smooth approval from the FDA and a great success in commercialization. The device eliminates skin itching completely in just seconds, no matter how bad the itching is, and keeps the itching away for up to 24 hours, and when the itching comes back, patients can use the device to quickly blow away the itching again, so to stay itching free. It can also clear up acne and eczema for some patients.
