Detachable Fan Base Storage for Compact Folding and Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fans have a troublesome and complicated storage process and a large footprint, which fails to meet user requirements for convenience and space efficiency.
Innovation Solution
A storable fan design featuring a detachable fan head, support rod, and base with accommodating grooves allows for easy assembly and disassembly without screws or nuts, enabling the fan head and support rod to be stored within the base, reducing storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan is stored by wrapping with a guard and placing in the corner, then the fan is protected, but the storage space occupied is large
Solution Approach 1:
The fan head is nested within the base structure, with the base serving as a containing cavity for the fan head components. This nesting arrangement allows the fan to be stored in a compact form factor, significantly reducing the storage space required compared to traditional storage methods.
Solution Approach 2:
The base serves multiple functions: it acts as the operational base during fan use and simultaneously serves as a storage container for the fan head when not in use. This multi-functionality eliminates the need for separate storage space, resolving the contradiction between protection and storage space occupation.
2Area of stationary object
If the fan is detached into many parts to store in a case, then the storage space is reduced, but the disassembly process becomes complicated
Solution Approach 1:
The fan is divided into two main separable components: the base and the fan head. This segmentation allows the fan head to be removed and stored within the base, reducing storage space without requiring complex disassembly into multiple small parts.
Solution Approach 2:
The storage function is merged with the base structure itself, which contains an integrated cavity designed to hold the fan head. This merging eliminates the need for separate storage cases and simplifies the storage process to a single insertion motion.
3Stability of the object's composition
If the base and support arm cannot be separated from fan body until many screws and nuts are detached, then the structural integrity is maintained, but the storage convenience is reduced
Solution Approach 1:
The connection between the base and fan head is segmented into a detachable interface that maintains structural integrity during operation but allows easy separation for storage. The support arm is designed as a separate component that can be quickly detached without requiring multiple fasteners.
Solution Approach 2:
The fastening mechanism is extracted and replaced with a snap-fit or bayonet-style connection that provides sufficient structural integrity during use but allows rapid detachment by a single motion, eliminating the need for multiple screws and nuts.

AI summary
A storable fan includes a fan head (1), a support rod (2) and a base (3) that are connected detachably. A first accommodating groove (301) and a second accommodating groove (302) are formed in the base (3), and the storable fan has a used state and a stored state. In response to the used state of the storable fan, the fan head (1), the support rod (2) and the base (3) are connected sequentially. In response to the stored state of the storable fan, the fan head (1) is stored in the first accommodating groove (301), and the support rod (2) is stored in the second accommodating groove (302). The fan head (1), the support rod (2) and the base (3) are connected detachably, for ease of detachment of the storable fan. Both the fan head (1) and the support rod (2) can be stored in the base (3). The storage process can be accomplished without detaching such fasteners as screws and nuts or by only using few fasteners. The storable fan is stored simply and conveniently, with a small footprint.
