Handheld Hair Dryer Controller Segmentation for Thin Handle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld hair drying apparatuses face aesthetic and usability issues due to the increasing size of controllers, which need to be housed within the handle, making them thicker and less convenient to use.
Innovation Solution
The controller is arranged inside a tube body separate from the handle, with a heater and flow-guiding elements to manage fluid flow and temperature, allowing for a thinner handle design while maintaining control over outflow temperature and flow volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the controller is arranged inside the handle, then the controller is protected and integrated, but the handle needs to be thickened which makes the apparatus unaesthetic and inconvenient to hold
Solution Approach 1:
The patent divides the controller into separate modules: a control module housed in the main body and a control button on the handle. This segmentation allows the handle to remain thin while maintaining full control functionality, resolving the contradiction between controller integration and handle thickness.
Solution Approach 2:
The control module is extracted from the handle and placed in the main body of the apparatus. Only essential control elements (buttons) remain on the handle, which significantly reduces handle thickness while preserving control capabilities, thus solving the aesthetic and ergonomic problems.
2Adaptability or versatility
If the controller size increases to accommodate more functions, then more functions are available, but the handle must be thickened to contain the controller
Solution Approach 1:
The control system is segmented into multiple components distributed across different locations: control buttons on the handle for ease of access, and the main control module in the body for housing additional functionality. This allows versatile functions without increasing handle dimensions.
Solution Approach 2:
The control architecture transitions from a single-location controller to a distributed control system across multiple dimensions (handle surface and main body interior). This spatial redistribution enables more functions without constraining handle thickness.
3Device complexity
If the controller is placed inside the handle, then integration is achieved, but user convenience deteriorates due to thickened handle and reduced grip comfort
Solution Approach 1:
Essential control elements are extracted and placed on the handle surface where users can easily access them, while the main control module is relocated to the body. This maintains operational convenience with a thin handle while achieving functional integration.
Solution Approach 2:
The control buttons on the handle act as intermediaries between the user and the main control module in the body. This intermediary arrangement allows users to operate the device conveniently with a thin handle while the main controller remains integrated in the body.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design prevents handle thickening, enhances user convenience, and prolongs the service life of the controller by isolating it from thermal energy, while ensuring even fluid flow and improved user experience.
Implementation Method 1
a heater sheathing around the tube body and arranged between the flow-guiding hole and the second opening
Implementation Method 2
the tube body is configured with a flow-guiding hole; the flow-guiding hole communicates with the second opening to form a second fluid channel

AI summary
The present disclosure relates to the field of blowing equipment, more particularly, to a handheld hair drying apparatus which includes a handle, a main body and a controller. The handle includes a fluid inlet. The main body includes a housing, a tube body and a first end cover; the housing is connected to the handle; the tube body passes through the housing coaxially and is connected to the housing; the tube body has a first opening and a second opening opposite to each other, the first end cover enclosing the first opening; a first fluid outlet is formed between an end of the tube body where the second opening is located, the first fluid outlet communicating with the fluid inlet to form a first fluid channel; and the controller is arranged inside the tube body.
