HAIR DRYER DESIGN
Role
Product design
Tool
SketchBook, Rhino, Grasshopper, Keyshot
Client
Tsinghua University (Student design project)
Duration
8 weeks
Background
I noticed that blow-drying hair usually takes more than 10 minutes, making people’s arms and hands feel tired, especially for longer hair. I analyzed the structure of the hair dryer and studied user behavior to identify pain points for improvement. Finally, I redesigned the hair dryer’s shape and button placement to make it more comfortable to hold and easier to control.
Product Structure Analysis
I disassembled a hair dryer and analyzed its structure.
System Mapping
I drew a system map to analyze the relationship between the hair dryer’s functions and structure.
User Behavior Analytics
I recorded the hair-drying process of people with varying hair lengths. Based on the recordings, I analyzed and summarized the basic steps of blow-drying and identified several pain points.
Gripping Method Analysis
I analyzed how people hold the handle of the hair dryer and the range of finger movement. Based on this, I determined the movement range of the fingers when holding the hair dryer.
Design Criterias
By modifying the handle shape and button positions on the hair dryer
Determining the ideal handle shape and button positions based on the analysis of gripping methods and hand structure.
Addressing issues of fatigue from prolonged use and challenges with one-handed operation
Based on user behavior analysis, it was found that people often experience hand fatigue when using hair dryers. Additionally, when styling hair, one hand is needed to shape the hair, leaving the hand holding the hair dryer unable to adjust its settings with just one hand.
Ensuring easier and more comfortable use of the hair dryer
The hair dryer should be easy to use and comfortable to grip.
Moodboard
I used gamepads as styling references because they can be gripped for hours without causing fatigue. Additionally, I drew inspiration from curved structures.
