Integrated Fan Blade Using Magnetic Material for Weight Reduction
Solution Overview
Problem
Conventional heat dissipation fans are heavy due to multiple components made of heavy materials, have complex assembly procedures, and high production costs, making them unsuitable for smaller, thinner electronic devices.
Innovation Solution
An integrated fan blade and fan design using a single magnetic material for the blade wheel, fan blade pivoting member, and blade pieces, with N-pole and S-pole zones arranged annularly and staggeringly, simplifying the structure and reducing weight and production complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional fan components (blade wheel, blade pieces, pivoting member) are made separately with connection structures, then the fan can be assembled from multiple parts, but the structure becomes complex and weight increases
Solution Approach 1:
The patent merges the blade wheel, blade pieces, and pivoting member into a single integrated fan blade component made from one magnetic material piece. This eliminates the need for separate connection structures and assembly steps, directly resolving the contradiction by combining multiple parts into one to reduce both structural complexity and manufacturing complexity.
2Reliability
If multiple materials with different properties are used for fan components, then each component can have optimized properties, but the overall weight increases and production cost rises
Solution Approach 1:
The patent uses a single magnetic material to fabricate the entire fan blade including the blade wheel, blade pieces, and pivoting member. This homogeneous material approach reduces the overall weight compared to using multiple heavy materials with connection structures, while still providing the necessary magnetic properties for electromagnetic induction with the stator.
3Ease of manufacture
If multiple components with connection structures are used, then the fan can be manufactured with specialized parts, but the assembly procedure becomes complicated and production cost increases
Solution Approach 1:
By integrating the blade wheel, blade pieces, and pivoting member into a single monolithic component, the patent eliminates multiple assembly steps and connection structures. This single-piece construction dramatically improves assembly efficiency and productivity while reducing production complexity, directly addressing the contradiction between manufacturing flexibility and assembly efficiency.

AI summary
An integrated fan blade and a fan having the same are provided. The fan includes a stator (1) and a fan blade (2); the stator (1) is provided with a stator pivoting member (10) and disposed on and electrically connected to a circuit board (11); the fan blade (2) includes a blade wheel (20), a fan blade pivoting member (21) formed at the center of the blade wheel (20) and axially extended; and a plurality of blade pieces (22) annularly formed at the outer periphery of the blade wheel (20), and the fan blade pivoting member (21) is pivoted with the stator pivoting member (10), wherein the fan blade (2) is formed with a magnetic material area and formed through an integrally forming means. With the fan blade (2) being integrally formed, the fan operating property can be effectively improved.
