Ceiling Fan Blade Covering Wing Conceals Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans have aesthetic appeal issues due to exposed bolt fasteners and complex, inconvenient assembly processes.
Innovation Solution
A ceiling fan design featuring a motor with a rotor and a bracket unit connected to angularly spaced blade-installation members, where each blade has a locking segment and a covering wing that register with adjacent members, and a mounting unit with fastener sets and securing members that secure the blades to the bracket unit, covering the fasteners for improved aesthetics and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolt fasteners are used to secure blades to the bracket, then the blades are firmly fixed, but the aesthetic appeal is adversely affected due to exposed fasteners
Solution Approach 1:
A decorative cover member is introduced as an intermediary element that conceals the exposed bolt fasteners while allowing the blades to remain securely fastened to the bracket, thus resolving the aesthetic issue without compromising the fixation strength
Solution Approach 2:
The solution moves from a two-dimensional surface problem (exposed fasteners on the blade surface) to a three-dimensional solution by adding a cover member that wraps around or overlays the fastener area, hiding it from view while maintaining structural integrity
2Shape
If decorative members are added to cover the fasteners, then aesthetic appeal is enhanced, but the assembly process becomes more complex and inconvenient
Solution Approach 1:
The decorative cover member is merged with the blade assembly structure itself, becoming an integrated component rather than a separate additive element. This integration allows the cover to be installed simultaneously with the blade mounting, eliminating the need for separate decorative component installation steps
Solution Approach 2:
The cover member serves multiple functions: it acts as a decorative element to hide fasteners, while also serving as part of the structural assembly process. The same component that provides aesthetics also facilitates or is integrated with the mechanical assembly, reducing overall complexity

AI summary
A ceiling fan includes a motor, a bracket unit connected fixedly on the motor and including a plurality of angularly spaced-apart blade-installation members, a plurality of blades and a mounting unit. Each blade has a locking segment registered with a respective one of the blade-installation members and a covering wing registered with a respective one of the blade-installation members. The locking segment and the covering wing of each of the blades are registered with two adjacent ones of the blade-installation members. The mounting unit includes a plurality of fastener sets, each securing the locking segment of a respective blade to a corresponding blade-installation member, and having a bottom end that is covered by a corresponding covering wing.
