Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans are limited in the volume and direction of their airflow, necessitating an accessory blade attachment to enhance these aspects.
Innovation Solution
A removable accessory blade attachment featuring a lightweight, bendable blade portion with a fan clip and control pivot, allowing for increased airflow volume and directional control by attaching to the ceiling fan blade and adjusting the angle of incidence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional ceiling fan blades are used, then the structure is simple, but the airflow volume and direction control are limited
Solution Approach 1:
The blade attachment is divided into separate functional components: a blade portion for generating airflow, a fan clip for attachment, and a control pivot for angle adjustment. This segmentation allows each component to be optimized independently while maintaining overall simplicity of the system.
Solution Approach 2:
The control pivot enables the blade portion to be dynamically adjusted to different angles of incidence, allowing the airflow direction and volume to be optimized based on operational requirements without changing the basic blade structure.
2Productivity
If the fan speed is increased to improve airflow volume, then the airflow volume increases, but the energy consumption and noise increase
Solution Approach 1:
Instead of changing the fan's rotational speed, the invention changes the aerodynamic parameters of the blade by adding an attachment with specific geometry and adjustable angle, thereby improving airflow volume without increasing energy consumption.
Solution Approach 2:
The blade attachment combines lightweight rigid material for structural integrity with a pivot mechanism for flexibility, creating a composite structure that optimizes aerodynamic performance without adding significant weight or complexity to the original fan system.
3Ease of operation
If the blade attachment angle is fixed, then the structure is simpler, but the airflow direction cannot be redirected to desired locations
Solution Approach 1:
The control pivot transforms the static blade attachment into a dynamic system that can be adjusted to different angles, enabling airflow redirection to various locations while maintaining a simple two-component structure (blade portion + pivot + fan clip).
Solution Approach 2:
The user can independently adjust the blade attachment angle without requiring tools or complex mechanisms, making the system self-adjustable and easy to operate while minimizing structural complexity.

AI summary
An accessory blade attachment adapted to removably attach to a ceiling fan blade of a ceiling fan is provided. The accessory blade attachment may include a blade portion and a pivotally connected fan clip, wherein the fan clip removably attaches to the trailing edge of the ceiling fan blade so that the blade portion may improve the volume and direction of airflow generated by the ceiling fan.
