Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of multiple fans in computing devices are cumbersome due to the use of screws and complex wiring, leading to difficulties in organizing and managing screws and electrical connections, which complicates the internal structure and airflow.
Innovation Solution
A fan bracket system with positioning pins, magnets, and quick connectors that facilitate easy attachment and detachment of fans, utilizing magnetic attraction and electrical connections through a circuit board assembly to simplify the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fasten fans to the radiator or chassis, then the connection is secure and reliable, but the number of screws increases exponentially with the number of fans, making assembly and disassembly cumbersome and difficult to organize
Solution Approach 1:
The patent combines multiple functions (mechanical fastening, electrical connection, and wire organization) into a single integrated clip component. The clip simultaneously secures the fan to the radiator, connects electrical wires, and organizes cable routing, eliminating the need for separate screws, connectors, and zip ties for each function.
Solution Approach 2:
The clip is designed as a multi-functional component that performs multiple tasks: it acts as a mechanical fastener to secure the fan, provides electrical connection points for wiring, and serves as a cable management element. This universal design reduces the total number of components needed when installing multiple fans.
2Reliability
If each fan is connected to power supply or motherboard through separate electrical connecting wires, then each fan has independent electrical connection, but the internal wiring becomes complicated and messy, affecting fan operation and cooling airflow
Solution Approach 1:
The patent merges electrical connection functions into the clip structure itself. The clip includes integrated connection points and channels that guide and secure wires, combining mechanical support and electrical connectivity into a single component rather than using separate wires and connectors for each fan.
Solution Approach 2:
The clip serves as an intermediary component between the fan and the power supply/motherboard connections. It provides a centralized interface that simplifies wire routing and connection management, acting as a mediator that organizes the electrical connections rather than allowing direct, messy wiring from each fan to the power source.
3Reliability
If multiple screws and electrical accessories are used for fan installation, then secure mechanical and electrical connections are achieved, but additional time and accessories (such as zip ties) are needed to organize wires
Solution Approach 1:
The patent combines mechanical fastening, electrical connection, and wire organization functions into a single integrated clip component. This multi-functional design eliminates the need for separate screws, connectors, and zip ties, reducing both the number of components and the time required for assembly.
Solution Approach 2:
The clip is pre-designed with integrated wire channels and connection points built into its structure. This preliminary design of the wire management features within the clip itself eliminates the need for separate post-installation wire organization steps using zip ties or other accessories.

AI summary
A fan bracket (100, 100A, 100B) for attaching or detaching at least one fan (200) comprising a frame (110), a plurality of positioning pins (120), a circuit board assembly (130), and a magnet (M1-M8) is provided. The positioning pins (120) disposed on the frame (110) are inserted into a plurality of assembling holes (T1-T4) of the fan (200) respectively, wherein different housing parts (A1, A2) of the fan (200) are assembled to each other via screws (SC1-SC4) locked in the assembling holes (T1-T4) respectively. The circuit board assembly (130) disposed in the frame (110) has at least one first quick connector (132, 132A, 132B) protruded out of the frame (110), wherein the first quick connector (132, 132A, 132B) is mated to a second quick connector (250) of the fan (200) in a process of the fan (200) assembling to the fan bracket (100, 100A, 100B) structurally. The magnet (M1-M8) disposed in the frame (110) attracts to at least one magnetic conducting sheet (241-248) of the fan (200).
