Light-emitting Fan Segmentation Reduces Mold Costs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of mold development for producing light-emitting fans with different lighting effects is a challenge due to the need for separate molds for varying light-emitting directions, which restricts the production of fans with diverse lighting effects.
Innovation Solution
A light-emitting fan configuration using a fan frame with a base, a first ring, and a second ring, where one ring is made of light-permeable plastic and the other of light-impermeable plastic, allowing for different lighting effects to be achieved using the same mold by varying the plastic materials of the rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate molds are used for fans with different light-emitting directions, then the lighting effects can be adapted to actual applications, but the mold cost increases
Solution Approach 1:
The fan frame is divided into multiple segments (base, first ring, second ring) that can be assembled in different configurations. Each ring can be made of different materials (light-permeable or light-impermeable plastic), allowing various lighting effects to be achieved by changing material combinations rather than creating entirely different molds
Solution Approach 2:
The patent employs segmentation by dividing the fan frame into modular components (base, first ring, second ring) that can be independently manufactured and assembled. This allows different material selections for each ring while using the same basic mold design, reducing the need for multiple specialized molds while maintaining adaptability for various lighting directions and effects
2Ease of manufacture
If one mold is used to manufacture fans with different lighting effects, then the mold development cost is reduced, but the manufacturing complexity increases
Solution Approach 1:
The fan frame is segmented into independent components (base, first ring, second ring) that can be manufactured using the same mold but with different material selections. This segmentation simplifies the molding process while the modular nature allows flexible assembly configurations to achieve different lighting effects
Solution Approach 2:
Different local qualities (light-permeable or light-impermeable properties) are assigned to different rings based on the desired lighting effect. The same mold can produce rings with different material properties, and the assembly configuration is adjusted locally to achieve the specific lighting direction or effect required
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the production of various light-emitting fans with different lighting effects using a single mold, reducing mold development costs and allowing for diverse lighting effects without increasing production expenses.
Implementation Method 1
One of the first ring and the second ring is made of light-permeable plastic, the other one of the first ring and the second ring is made of light-impermeable plastic, and light from the light-emitting component is emitted through the first ring or the second ring

AI summary
This disclosure relates to a light-emitting fan includes a fan frame, an impeller, and a light-emitting component. The fan frame includes a base, a first ring, and a second ring. The first ring is disposed on the base. The second ring is disposed on the first ring. The first ring is located between the base and the second ring, and the first ring and the second ring together form an accommodating space. The impeller is located in the accommodating space and rotatably disposed on the base. The light-emitting component is located in the first ring or the second ring. One of the first ring and the second ring is made of light-permeable plastic, the other one is made of light-impermeable plastic, and light from the light-emitting component is emitted through the first or second ring.
