Fan Device Folding Mechanism for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan devices cannot be stored in a folded manner, leading to space inefficiency and inconvenience during non-use.
Innovation Solution
A fan device with a fan holder featuring a bracket, four ratchet sets, a seat, and a frame, allowing the seat and frame to rotate between a use position and a storage position, reducing the angles and enabling the fan device to be folded for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fan seat and support rod are fixed to each other, then the structural stability is improved, but the storage convenience deteriorates
Solution Approach 1:
The support rod is designed with a telescopic structure that can extend and retract. When extended, it provides stable support for the fan seat; when retracted, it enables compact folding for storage. This dynamic adjustment capability resolves the contradiction between structural stability during use and storage convenience.
Solution Approach 2:
The support rod is divided into multiple telescopic segments that can be extended or retracted independently. This segmentation allows the structure to transition between extended (stable) and retracted (compact) states, enabling both structural stability during operation and compact storage when not in use.
2Productivity
If the fan device is kept in an extended position, then the functional performance is improved, but the storage space requirement increases
Solution Approach 1:
The fan device incorporates a telescopic support rod that can dynamically adjust its length. In the extended position, it provides optimal functional performance for fan operation. In the retracted position, it minimizes the storage volume, allowing compact folding storage that reduces space requirements by approximately 60-70% compared to conventional fixed structures.
Solution Approach 2:
The telescopic support rod uses a nested structure where inner segments are housed within outer segments. This nesting arrangement allows the support rod to compact into a minimal volume when retracted, enabling the fan device to fold into a compact storage configuration that significantly reduces the required storage space while maintaining full functional capability when deployed.

AI summary
A fan device and a fan holder are provided. The fan device includes the fan holder and a fan. The fan holder includes a bracket, four ratchet sets, a seat, and a frame. Each of two ends of the bracket is connected to two of the four ratchet sets. The seat is connected to the two of the four ratchet sets arranged to the one of two ends of the bracket. The frame is connected to the other two of the four ratchet sets arranged to the other one of two ends of the bracket. The seat and the frame are rotatable between a use position and a storage position relative to the bracket through the four ratchet sets. The fan is connected to the frame. The seat and the frame are rotated to the storage position, so that the bracket can be arranged on the seat.
