Hair Dryer Sensor Assembly for Diffuser Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hair dryers struggle to easily couple with diffusers that have additional functions like anion care and LED care, and to recognize the correct orientation of these diffusers for proper function.
Innovation Solution
A hair dryer design featuring a sensor assembly at the center of the gas discharger that senses the diffuser's magnetism, allowing for easy coupling regardless of the diffuser's rotation direction, and a coupling portion with a curved auxiliary portion to facilitate secure attachment and gas discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a diffuser with additional functions (anion care, LED care) is coupled to the hair dryer, then the hair dryer can provide additional care functions, but the hair dryer must recognize the coupling direction to supply power correctly
Solution Approach 1:
The patent employs asymmetric magnetic pole arrangements (N and S poles positioned at specific locations) in both the diffuser and hair dryer. This asymmetric configuration creates a magnetic coupling mechanism that automatically recognizes and aligns the correct coupling direction, eliminating the need for manual orientation while enabling additional care functions.
2Reliability
If the hair dryer requires recognition of diffuser coupling direction, then power can be supplied correctly to additional functions, but the coupling process becomes more complex
Solution Approach 1:
The patent replaces complex mechanical coupling recognition mechanisms with a magnetic field-based system. Magnetic sensors detect the orientation of magnetic poles, automatically determining the correct coupling direction and enabling reliable power supply to additional functions without increasing mechanical complexity.
3Ease of manufacture
If the gas discharger has a fixed structure, then manufacturing is simpler, but the coupling portion may expose users to hot surfaces
Solution Approach 1:
The patent introduces a curved coupling portion with recessed configuration in the gas discharger. This curved structure redirects the gas flow away from the coupling area, preventing hot gas from contacting the user's hand while maintaining a relatively simple manufacturing process through curved surface formation.

AI summary
A hair dryer may be provided, the hair dryer comprising: a body having a gas outlet part through which gas is discharged out of the body; and a handle extending from the body, wherein: the gas outlet part comprises a sensor unit which is provided at the center of the gas outlet part to sense coupling between the body and a diffuser coupled to the body and a coupler which is annularly provided along the circumference of the gas outlet part to surround the sensor unit; the diffuser is coupled to the body through the coupler; and the sensor unit is provided to be opposite to the diffuser. As such, a user can easily couple a diffuser to the hair dryer. In addition, the user can easily use additional functions of the diffuser. That is, user convenience can be enhanced.
