Fan Blade Assembly Openwork Design for Frame Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan blade assemblies with flexible materials require complex and expensive frames, which is a deficiency in existing aesthetically enhanced fan designs.
Innovation Solution
A fan blade assembly with an openwork design on the blade iron and fan blade, featuring a retention member and cover, where the openwork is integral with either the proximal or distal ends, and the fixture is integral with the other end, allowing for angular disposition of the blade iron to secure the fan blade effectively while preventing warping and twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If flexible materials (cloth, canvas, woven wicker, natural leaf) are used for fan blades to enhance aesthetics, then the visual appearance is improved, but the structural complexity and manufacturing cost increase due to the requirement for frames
Solution Approach 1:
The invention extracts and eliminates the complex frame structure from the fan blade assembly. Instead of using traditional rigid frames to support flexible blade materials, the patent employs a blade iron with an integrated openwork design that directly supports the flexible material without requiring additional framing components, thereby simplifying the overall structure while maintaining aesthetic appearance
Solution Approach 2:
The invention merges the support structure and blade assembly into a single integrated unit. The blade iron with its openwork design combines the functions of structural support and aesthetic presentation, eliminating the need for separate frame components and reducing manufacturing complexity while maintaining the ability to support flexible materials
2Strength
If traditional rigid frames are used to support flexible blade materials, then structural support is provided, but manufacturing cost and complexity increase
Solution Approach 1:
The invention removes the complex multi-component frame structure and replaces it with a single blade iron component that provides the necessary structural support. This extraction of unnecessary components simplifies manufacturing while maintaining adequate structural strength to support flexible blade materials
Solution Approach 2:
The invention changes the structural parameter from rigid frame construction to a blade iron with openwork design. This parameter change allows the structure to provide sufficient support through optimized geometry rather than through dense rigid materials, reducing manufacturing cost while maintaining structural integrity

AI summary
A fan blade assembly includes a fan blade and a blade iron. The proximal end of the blade iron is configured for securement to a conventional, commercially available fan motor. An openwork defines the perimeter of the fan blade. A decorative cover spans and is secured to the openwork. The distal end of the blade iron includes a fixture for detachably receiving and holding the proximal end of the openwork.
