Fluffing Nozzle Airflow Diffusion for Uniform Hair Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair dryers lack uniform air output, leading to potential hair damage and styling difficulties due to inconsistent air speeds, and the rotary blade design can cause hair knots.
Innovation Solution
A fluffing and styling nozzle with a diffusing shell, mesh cylinder, flow dividing platform, and baffle plate that divides and diffuses air flow, reducing speed and ensuring uniform output through multiple outlets and mesh openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotary nozzle with high air speed is used to blow-dry hair quickly, then productivity is improved, but the hair is easily injured due to high air speed
Solution Approach 1:
The nozzle divides the air flow into multiple streams using flow dividing platforms and baffle plates, creating multiple outlet channels instead of a single high-speed jet. This segments the concentrated air flow into distributed lower-speed streams that cover a wider area, improving blow-drying efficiency while reducing hair damage from high-velocity impact
Solution Approach 2:
The patent applies different outlet configurations to different regions of the nozzle - the center outlet hole provides focused air flow for root volume, while the peripheral gap channels provide distributed air flow for surface styling. This local differentiation allows optimized air flow characteristics for different hair styling needs without requiring uniformly high speed across all outlets
2Object-affected harmful factors
If the air speed is reduced to protect hair, then hair injury is minimized, but the hair is blow-dried and styled uneasily due to low air speed
Solution Approach 1:
By segmenting the air flow into multiple outlets, the system maintains adequate air velocity at each outlet for effective styling while distributing the total air flow across multiple channels. This ensures each local stream has sufficient speed for styling effectiveness without requiring any single stream to be excessively fast, which would cause hair damage
3Productivity
If a rotary blade is used to gather hair into the hair dryer, then productivity is improved, but the hair is knotted which is not conducive to normal use
Solution Approach 1:
The patent removes the rotary blade component entirely from the nozzle design. Instead of using mechanical rotation to gather and direct hair, the invention relies on the diffusing shell shape and multiple outlet airflow patterns to naturally guide and distribute hair. This extraction of the problematic rotary blade eliminates hair knotting while the diffusing structure maintains effective hair gathering and styling capability

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 nozzle achieves uniform air distribution, reducing hair damage and facilitating easier styling by minimizing high-speed air impact and preventing hair knots.
Implementation Method 1
gases flowing out of the two portions flow out uniformly through mesh openings of the mesh cylinder
Implementation Method 2
the flow dividing platform and the baffle plate are arranged on the diffusing shell, the baffle plate is arranged at the bottom of the flow dividing platform, and the baffle plate and the magnetic part supporting rib reverse side form a side surface gap flow channel
Implementation Method 3
gas flowing out of the middle air outlet hole enters the internal diffusing chamber
