Fan Assembly Protrusion-Slot Mounting Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting and dismounting fans in computer systems are labor-intensive and inconvenient due to the need for screwing through holes, which complicates the assembly and disassembly process.
Innovation Solution
A fan assembly comprising a mounting bracket with a clamp panel structure and a fixing bracket with protrusions and slots, allowing for secure engagement and easy attachment of the fan, reducing the complexity of assembly and disassembly through a connector system that uses elastic deformation for alignment and secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw mounting means are used to secure the fan to the chassis, then the fan can be firmly mounted, but the assembly and disassembly process becomes labor-intensive and inconvenient
Solution Approach 1:
The mounting system is divided into separate functional components: a mounting bracket with clamp panels for securing the fan, and a fixing bracket with protrusions and slots for positioning. This segmentation allows each component to perform its specific function independently, enabling secure mounting while simplifying the overall assembly process through modular installation.
Solution Approach 2:
The mounting bracket acts as an intermediary component between the fan and the chassis. Instead of directly screwing the fan to the chassis, the mounting bracket provides a intermediate structure with clamp panels that secure the fan, while the fixing bracket with protrusions and slots provides an intermediary positioning mechanism that simplifies alignment and attachment.
2Reliability
If through holes and screws are used for mounting, then the fan can be securely fixed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The mounting bracket and fixing bracket are pre-configured with clamp panels, protrusions, and slots during manufacturing. These preliminary structural preparations eliminate the need for on-site drilling, threading, and screwing operations, allowing for rapid assembly by simply engaging the pre-formed connection features.
Solution Approach 2:
The traditional screw-based mechanical fastening system is replaced with a protrusion-slot engagement system combined with clamp panels. This substitution eliminates the need for screws, drill holes, and threading operations, significantly reducing assembly complexity and time while maintaining secure fixing through the interlocking protrusion and slot mechanism.
3Reliability
If traditional screw mounting is used, then the fan can be securely mounted, but the disassembly process becomes labor-intensive
Solution Approach 1:
The mounting system transitions from a static screw-fastened connection to a dynamic engagement system where the clamp panels can be released and the protrusions can be disengaged from the slots. This dynamic design allows for easy disassembly by simply releasing the clamp panels and pulling the protrusions out of the slots, while maintaining stable mounting during operation through the secure engagement of the same features.

AI summary
A fan assembly includes a mounting bracket, a fan mounted on the mounting bracket and a fixing bracket. The fixing bracket includes two sidewalls mounted on two sides of the fan and a connecting wall mounted on a top of the fan. Two first protrusions are located on each side of the fan; two second protrusions adjacent to the two first protrusions are located on each side of the fan; two first slots are defined in each of the two sidewalls corresponding to the first protrusions; a plurality of second slots are defined in the connecting wall corresponding to the second protrusions; the first protrusions are engaged with the first slots; the second protrusions are engaged with the second slots; and one of the two sidewalls is mounted to the mounting bracket to fix the fan and the fixing bracket on the mounting bracket.
