BACKGROUND

Prolonged Use & Fatigue

Prolonged Use & Fatigue

Prolonged Use & Fatigue

Blow-drying hair often takes over ten minutes, which can lead to arm and hand fatigue, especially for users with longer hair. By examining the structure of conventional hair dryers and common usage patterns, the project identified opportunities to improve comfort and control through redesigning the hair dryer’s form.

CHALLENGES

1

1

Reducing Use Fatigue

Addressing fatigue caused by prolonged holding and repeated wrist movements during blow-drying.

2

2

Ergonomic Hand Interaction

As a hand-held device, hair dryers interact closely with the user’s hand, requiring ergonomic consideration.

RESEARCH

Functional Breakdown

Functional Breakdown

I disassembled a hair dryer to analyse the functions of individual components and how they work together as a system.

Usage Observation

Usage Observation

Usage Observation

I recorded the hair-drying process of several people with long hair. Based on these observations, I analysed the typical blow-drying workflow and identified key pain points.

Grip & Finger Movement Analysis

Grip & Finger Movement Analysis

I analyzed user grip patterns and finger movement ranges to identify key interaction zones on the handle.

IDEATION

Ergonomic Handle Refinement

Design Details

A left-high, right-low control module form provides more comfortable thumb placement, with the two buttons positioned according to the thumb’s natural range of motion.

Smooth, rounded edges enhance comfort during gripping, while transparent structural elements provide internal support.

KEY TAKEAWAYS

Ergonomic Considerations

Ergonomic Considerations

Ergonomic Considerations

This project highlighted that design should be grounded in real usage behavior. By analysing grip patterns, finger movement, and prolonged use scenarios, I gained a clearer understanding of how users interact with a hair dryer and applied ergonomic considerations to inform the handle design.
