Adjustable Clip Airflow Hood for Hair Dryer Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airflow hoods for hair dryers are incompatible with hair dryers of different specifications and are bulky, making them inconvenient to use and carry.
Innovation Solution
An airflow hood with a rigid sleeve and clamping mechanisms featuring torsion springs and adjustable clips, allowing for secure attachment to various hair dryer sizes, and a flexible silicone shell with folding portions for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a soft silicone sleeve is used for the fixing part, then it can easily adapt to hair dryer outlets and is not easy to loosen, but it cannot match hair dryers of different sizes
Solution Approach 1:
The fixing component uses adjustable clips that can dynamically change their position and clamping force. The clips are designed to be movable along the sleeve and can be adjusted to different positions to accommodate various outlet diameters, transforming a static structure into a dynamic one that adapts to different conditions.
Solution Approach 2:
The fixing component changes its physical parameters (clamping position, clamping force) through the adjustable clips. By modifying the position of clips along the sleeve and adjusting the pressing block force, the system can adapt to different outlet sizes while maintaining reliable fixation.
2Productivity
If the airflow hood is designed with large volume to provide sufficient drying space, then it can blow to most of the hair at one time, but it is inconvenient to carry
Solution Approach 1:
The airflow shell is made of flexible silicone material that can be folded and compressed. This flexible shell maintains its functional volume during use for effective hair drying, but can be collapsed into a compact form for portable storage, resolving the contradiction between drying space and carry convenience.
Solution Approach 2:
The airflow hood transitions between two dynamic states: an expanded state during use that provides sufficient drying space, and a compressed folded state for portability. The folding design allows the structure to dynamically change its volume based on operational needs.
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
Enables easy and secure connection to hair dryers of different specifications, with a compact design that simplifies handling and ensures efficient drying while preventing overheating.
Implementation Method 1
a torsion spring arranged between the clip body and the sleeve such that a clamping end of the clip body tends to move away from an inner wall of the sleeve
Implementation Method 2
the frictional properties of the silicone make the silicone soft cover not easy to loosen after it is connected to the hair dryer
