Foldable Portable Fan Base for Stable Use and Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fans with bases for support increase the overall volume, making them cumbersome for transport and storage.
Innovation Solution
A fan design featuring a protective outer and inner shell, a rotatable base, a support plate with a spring and clamping block, and a non-slip pad, allowing the base to be folded parallel to the device shell for reduced storage volume and enhanced stability during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a base is added to support the fan body during operation, then the stability of the fan is improved, but the overall volume increases, making it less convenient for transport and storage
Solution Approach 1:
The base is designed to be rotatable relative to the fan body, allowing it to change its spatial configuration. During operation, the base extends outward to provide stability. During storage, the base rotates to fold parallel to the fan body, minimizing the overall volume. This dynamic adjustment resolves the contradiction between stability and compact storage.
2Strength
If the base is made extendable for stability, then the support capability is improved, but the storage convenience deteriorates
Solution Approach 1:
The base incorporates a rotation mechanism that enables it to transition between an extended configuration for support and a folded configuration for compact storage. This dynamic design allows the base to adapt its form factor based on operational requirements, resolving the contradiction between support capability and storage convenience.
3Object-affected harmful factors
If a protective shell structure is added to protect fan blades, then the safety is improved, but the device complexity increases
Solution Approach 1:
The protective shell is integrated with the fan body as a unified structure rather than a separate component. The shell encapsulates the fan blades and motor assembly, providing protection while maintaining a compact overall design. This integration approach provides safety without significantly increasing device 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
Enables convenient storage and stable operation by protecting users from rotating blades and minimizing storage space through a collapsible design.
Implementation Method 1
The support plate is provided with a spring, which is located inside the support plate and is fixedly connected to the support plate
Implementation Method 2
The base is located below the protective inner shell and is rotatably connected to the bottom of the protective inner shell

AI summary
A fan that is convenient for storage includes protective outer shell, protective inner shell, base, device shell, control board, switch, power motor, and fan blades. During use, pressing switch at the center of the back of device shell causes control board to control operation of power motor, which drives fan blades to rotate. The wind generated by the rotation of fan blades blows through the hollowed-out shapes of protective outer shell and protective inner shell towards the user. The protective outer shell and protective inner shell protect the user. After use, pressing switch at the back of device shell stops power motor, causing the fan to cease operation. At this point, base is rotated in the direction of device shell until base is parallel to device shell.
