Assembling structure for a ceiling fan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans mounted via an assembling structure with a hanging tube have an unstable connection to the ceiling due to low structural strength, primarily because the hanging tube is assembled with a bolt, leading to instability and increased assembly time.
Innovation Solution
The proposed assembling structure features a hanging rod and hanging ball with a large contact area, where the rod's bending edge abuts the ball's supporting platform, enhancing stability without the need for screws, thus eliminating screw exposure and rusting, and includes a non-metal rod fixing component to reduce abrasion and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the hanging tube is assembled with a bolt, then the assembly is simple, but the structural strength is low and connection is unstable
Solution Approach 1:
The patent replaces the traditional bolted mechanical connection system with a welding connection system. The hanging tube is welded directly to the ceiling support structure, eliminating the need for bolts and nuts. This substitution provides superior structural strength and stability while maintaining assembly simplicity through the streamlined welding process.
2Ease of operation
If the hanging tube is assembled with a bolt, then the assembly process is straightforward, but the assembly time is increased
Solution Approach 1:
The patent replaces the multi-step bolted assembly process (positioning, inserting bolts, tightening nuts, verifying stability) with a single welding operation. This eliminates the time-consuming steps of thread engagement and torque application, reducing overall assembly time while maintaining operational simplicity through the efficient welding procedure.
3Ease of manufacture
If bolts are used for connection, then the components can be easily assembled, but screw exposure and rusting occur
Solution Approach 1:
The patent replaces the exposed bolted connection system with a welded connection that eliminates visible fasteners. The welding process creates a seamless joint between the hanging tube and ceiling support, removing the exposure of bolts and nuts to the environment. This prevents rusting and corrosion issues associated with exposed metal fasteners while maintaining assembly ease through the welding process.

AI summary
An assembling structure for a ceiling fan has a hanging rod, a hanging ball, and a hanging bracket. A top end of the hanging rod forms a bending edge. The hanging ball has a first hole and a supporting wall. The hanging rod is mounted through the first hole. The supporting wall has a supporting platform abutting a bottom surface of the bending edge. The hanging bracket has a ball mounting segment and a ceiling mounting segment adapted to be mounted to a ceiling. The ball mounting segment has a hanging hole. A diameter of the hanging hole is smaller than a diameter of the hanging ball. The hanging ball abuts downward a periphery of the hanging hole. The hanging rod is mounted through the hanging hole. With a large contact area between the hanging rod and the hanging ball, the structural strength is high.
