Hair Addition Drying System with Laminar Air Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair drying methods for hair additions are inefficient, causing tangling and damage due to turbulent air convection and uneven drying, particularly when drying multiple units simultaneously.
Innovation Solution
A hair drying system with an elongated internal chamber featuring ducted air intake and exhaust systems that create a laminar air flow, combined with an internal support assembly to suspend hair additions, ensuring air flows parallel to the hair strands, and a diffuser to control heat and air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hair additions are placed on a surface for drying using a hand-held dryer, then the drying process can be performed, but the hair additions become tangled and damaged due to turbulent air convection
Solution Approach 1:
The drying chamber is segmented into multiple sections with individual air flow paths, allowing separate control of air flow for different hair addition units. This prevents turbulent air from causing tangling while maintaining effective drying for each unit.
Solution Approach 2:
A laminar flow screen is introduced as an intermediary component between the air source and the hair additions. This screen transforms turbulent air flow into laminar flow, eliminating the harmful tangling effect while preserving the drying function.
2Productivity
If multiple hair additions are dried simultaneously on a surface, then productivity increases, but drying uniformity decreases due to blocked air convection
Solution Approach 1:
The drying system divides the chamber into multiple independent drying zones, each with its own air intake and exhaust paths. This allows multiple hair additions to be dried simultaneously while maintaining uniform air flow and drying conditions in each zone.
Solution Approach 2:
The system transitions from two-dimensional surface drying to three-dimensional suspended drying. Hair additions are hung vertically in the chamber, allowing air to circulate around all surfaces of each unit, ensuring uniform drying from all directions simultaneously.
3Loss of time
If air is blown perpendicular to hair addition strands, then drying may occur, but the hair strands become tangled
Solution Approach 1:
Instead of blowing air perpendicular to the hair strands, the system directs air flow parallel to the strand length. This inversion of the air flow direction eliminates tangling while maintaining efficient drying along the entire length of each strand.
Solution Approach 2:
The air flow regime is changed from turbulent to laminar flow, and the direction is changed from perpendicular to parallel relative to the hair strands. These parameter changes eliminate the tangling mechanism while preserving the drying efficiency.
4Ease of manufacture
If hair additions rest on a surface during drying, then they can be dried, but the surface blocks air convection causing uneven drying
Solution Approach 1:
The system moves from two-dimensional surface contact drying to three-dimensional suspended drying. Hair additions are hung vertically, exposing all surfaces to air flow and eliminating the blocking effect of any surface, thereby achieving uniform drying.
Solution Approach 2:
The supporting surface is removed from the drying process. Instead of resting on a surface that blocks air flow, hair additions are suspended in mid-air, allowing complete air circulation around each unit for uniform drying from all surfaces.
