Ceiling Fan Blade Quick Assembly with Concealed Stop Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick assembly methods for ceiling fan blades result in an unstable structure and expose the stop strip, compromising the integrity and external appearance of the fan.
Innovation Solution
A quick assembly blade design featuring a pan-shaped blade frame with projecting bases, a stop member, and a press board, where the press board is pushed backward to engage the blade firmly with the frame, and the stop member is concealed within the press board, ensuring stability and aesthetic integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the engage holes of the blade are mutually engaged with the studs of the blade frame, then the assembly can be quickly assembled, but the structure becomes unstable and the blade cannot be firmly secured
Solution Approach 1:
The patent combines multiple fastening functions into a single press board component that simultaneously provides pressing force through large-area contact and positioning through engage holes, merging the functions of stabilization and positioning into one element that resolves the contradiction between quick assembly and structural stability
Solution Approach 2:
The press board acts as an intermediary element between the blade and blade frame, providing a large-area pressing surface that distributes force and enhances stability while the engage holes provide additional positioning, thus mediating between the need for quick assembly and firm securing
2Ease of operation
If the stop member is used to prevent the blade from moving horizontally, then the blade can be quickly assembled, but the stop strip is exposed to the outside and spoils the integrity and external appearance
Solution Approach 1:
The stop member is nested within the receiving hole of the press board, with the stop portion positioned inside the press board structure rather than exposed externally. This nesting arrangement maintains the horizontal positioning function while concealing the stop member from external view, thus preserving the aesthetic appearance

AI summary
A quick assembly blade for a ceiling fan includes a blade frame, one stop member, a blade and a press board. The blade frame has a pan-shaped body fixed with three projecting bases protruding upward. The blade and the press board are respectively and correspondingly bored with insert holes and engage holes to be respectively fitted on the projecting bases. The stop member is secured on one of the projecting bases and inserted through a through hole of said blade, having its free end formed with a stop portion received in a receiving hole of said press board and stuck on the inner wall of the receiving hole. When the press board is moved backward horizontally, the blade can be quickly and stably assembled on the blade frame, and the stop member is concealed in the receiving hole not exposed to outside, able to elevate the integral beauty of the ceiling fan.
