Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat dissipation fans are not visually appealing and do not allow for aesthetic enhancement when exposed, as they are not designed to be decorative or light-permeable, compromising the appearance of products they are installed in.
Innovation Solution
A heat dissipation fan structure incorporating a housing, first and second circuit boards, a light guide plate, a light-permeable element, and a vane assembly, which allows light emission and diffusion to create a pattern visible through a light-permeable material, enabling both heat dissipation and decorative light display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional heat dissipation fans are used, then heat dissipation function is achieved, but aesthetic appearance is compromised
Solution Approach 1:
The patent combines the heat dissipation fan function with a light guide plate and light-permeable elements to create a dual-functional component that serves both thermal management and aesthetic illumination purposes, eliminating the need for separate decorative lighting components
Solution Approach 2:
The fan assembly is designed to perform multiple functions simultaneously: heat dissipation through fan operation and aesthetic light display through the light guide plate and light-permeable elements, making the component universally useful for both functional and decorative requirements
2Shape
If a light guide plate and light-permeable elements are added to the fan, then aesthetic light display is achieved, but device complexity increases
Solution Approach 1:
The light guide plate, light-permeable elements, and fan structure are merged into a single integrated assembly where components serve multiple purposes: the light guide plate diffuses light while also serving as part of the housing structure, and light-permeable elements are incorporated directly into the fan blade design
Solution Approach 2:
The patent employs a nested structure where the light-permeable element is positioned within the fan blade, the light guide plate is integrated into the housing surrounding the motor, and multiple components are layered concentrically around the central motor assembly, creating a compact nested arrangement
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
The fan structure effectively dissipates heat while showcasing a pattern of light, enhancing the aesthetic appeal of the product and the fan itself, providing a functional and visually pleasing solution.
Implementation Method 1
The light guide plate faces the light emission unit in order to evenly diffuse the light emitted by the light emission unit
Implementation Method 2
The light-blocking portion is made of a material impermeable to light while the light-permeable portion allows passage of light

AI summary
A heat dissipation fan structure capable of showing a pattern of light includes a circuit board, a light guide plate, a light-permeable element, and a vane assembly sequentially connected together. The circuit board is provided with a light emission unit. The vane assembly has a light-permeable wall made of a light-permeable material. The light emitted by the light emission unit is evenly diffused by the light guide plate, passes through the light-permeable element, and is rendered into a specific pattern (e.g., a decorative design and/or characters) by the light-permeable portion of the light-permeable element, wherein the light-permeable portion is shaped according to user needs. The light-permeable material of the light-permeable wall of the vane assembly allows the decorative design and/or characters of light to be seen externally. The heat dissipation fan structure, therefore, can show a pattern of light in addition to dissipating heat.
