Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable fans are inconvenient to use outdoors as they require manual handling and often have suboptimal wind efficiency and portability.
Innovation Solution
A portable fan design with a housing body containing a fan assembly and a power supply assembly offset along a preset direction, allowing for a compact and efficient air path, and equipped with clamping devices for hands-free use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the fan is made smaller and more portable, then portability is improved, but the ability to hold and use the fan freely is reduced
Solution Approach 1:
The fan is divided into separate functional modules: a clamping mechanism that attaches to clothing or objects, a housing containing the fan assembly, and a power supply unit. This segmentation allows the fan to be worn or attached without constant manual handling while maintaining compact size.
Solution Approach 2:
A clamping device acts as an intermediary between the user and the fan, allowing the fan to be securely attached to clothing or objects. This mediator enables hands-free operation while maintaining the compact portable design.
2Volume of moving object
If the fan assembly and power supply are arranged in a compact configuration, then portability is improved, but wind efficiency may be compromised
Solution Approach 1:
The power supply assembly is positioned offset from the fan assembly along a direction perpendicular to the main air flow path. This spatial arrangement in another dimension allows compact overall packaging while maintaining sufficient space for efficient air circulation and wind generation.
Solution Approach 2:
The power supply assembly is nested within the housing body alongside the fan assembly, with components arranged in a space-efficient configuration. The air inlet, fan assembly, and air outlet are positioned to create an effective air path while the power supply occupies unused spatial volume without interfering with wind efficiency.
3Ease of operation
If clamping devices are added for hands-free use, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The clamping device is designed to attach automatically to clothing or objects through simple mechanical engagement. The user only needs to fasten the clamping mechanism once, and it maintains secure attachment without requiring continuous adjustment or complex control systems.
Solution Approach 2:
The clamping function is extracted as a separate, dedicated mechanism rather than being integrated into the main fan housing. This allows the clamping device to be optimized for its specific function while keeping the overall design modular and manageable in complexity.
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
Enhances wind efficiency, improves portability, and provides a hands-free cooling experience by allowing the fan to be securely attached to external objects, thus increasing usability and convenience.
Implementation Method 1
the fan assembly is configured to drive an air flow to flow from the air inlet to the air outlet
Implementation Method 2
the first clamping device is connected to one side of the housing body, and is configured to form a clamping space with the housing body for clamping an external object

AI summary
A portable fan includes a housing body, a fan assembly, a power supply assembly and a first clamping device. The housing body is provided with an accommodating chamber, an air inlet, and an air outlet; the air outlet, at least part of the accommodating chamber and the air inlet are communicated to each other in sequence along a first preset direction. The fan assembly is located within the accommodating chamber and between the air inlet and the air outlet, and is configured to drive an air flow to flow from the air inlet to the air outlet. The power supply assembly is located within the accommodating chamber, the power supply assembly is offset from a projection of the fan assembly along the first preset direction, and the power supply assembly is electrically connected to the fan assembly to supply power to the fan assembly.
