Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair styling devices often suffer from inefficiencies due to improper operation, where hair is not sufficiently wound over the cooling surface, leading to inadequate cooling and shaping of hair, which counteracts the desired styling result.
Innovation Solution
A hair styling device with determination and control means to ensure correct use of the cooling surface, featuring a cooling device with adjustable cooling air passage openings and a blower that varies airflow based on hair coverage, and optional suction for enhanced cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cooling surface is made larger to improve cooling efficiency, then the cooling effect is enhanced, but the device complexity and difficulty of operation increase due to improper hair winding
Solution Approach 1:
The patent implements feedback through sensors that detect whether hair is properly wound around the cooling surface. Based on this detection, the system automatically adjusts cooling air passage openings to ensure optimal cooling only when hair is correctly positioned, preventing waste and ensuring reliable operation
Solution Approach 2:
The cooling air passage openings are made dynamically adjustable based on hair coverage detection. The system transitions from a static cooling design to a dynamic one where the cooling effect is modulated in real-time according to the actual hair positioning, resolving the contradiction between cooling efficiency and operational reliability
2Temperature
If active cooling with a blower is added to enhance cooling efficiency, then the cooling effect is improved, but the device complexity increases
Solution Approach 1:
The blower and cooling system are designed to activate automatically based on sensor detection of hair positioning. The system serves itself by using detected hair coverage to control cooling activation, eliminating the need for complex manual control mechanisms while maintaining high cooling efficiency
Solution Approach 2:
The patent uses pneumatic principles with a blower to deliver controlled cooling air through adjustable passage openings. This pneumatic approach provides efficient cooling with relatively simple device structure, avoiding the need for complex mechanical cooling systems
3Temperature
If cooling air passage openings are provided to improve cooling, then the cooling effect is enhanced, but energy is wasted when hair is not properly positioned
Solution Approach 1:
Sensor feedback mechanisms detect whether hair is properly wound around the cooling surface and use this information to control the opening of cooling air passages. This ensures cooling air is delivered only when needed, eliminating energy waste while maintaining effective cooling when hair is correctly positioned
Solution Approach 2:
The cooling air passage openings are dynamically controlled based on real-time detection of hair positioning. The system adjusts the cooling air flow state according to actual operational conditions, preventing energy waste during improper operation while ensuring adequate cooling during proper use
