Solution Overview
Problem
Conventional air fan damping structures require additional tools and increase installation time due to complex assembly processes, which complicates the installation and removal of air fans, leading to inefficiencies in reducing vibration and noise.
Innovation Solution
An air fan damping structure featuring a fan frame with a hollow first buffer and a holding member, including an inserting portion and a depressing portion, which form a retaining relationship to simplify installation without tools, utilizing a first buffer with a through hole and a second anchor portion for secure anchoring, along with additional buffers for enhanced cushioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional damping structure with screw fastening is used, then vibration damping effect is achieved, but installation time increases and installation becomes tedious
Solution Approach 1:
The damping structure is divided into separate functional components: a damping element (first buffer) for vibration absorption and a holding member for mechanical attachment. This segmentation allows each component to be optimized independently and simplifies the assembly process by enabling tool-free installation through the holding member's inserting portion that passes through the buffer's through hole.
Solution Approach 2:
The holding member is designed with an inserting portion that can be manually pushed through the through hole of the first buffer without requiring external tools. The retaining portions (latch member and latch trough) automatically engage to secure the assembly, making the installation process self-sufficient and eliminating the need for screwdrivers or other fastening tools.
2Object-affected harmful factors
If a conventional damping structure with screw fastening is used, then vibration damping effect is achieved, but installation complexity increases
Solution Approach 1:
The fastening function is extracted from the damping element itself and separated into a dedicated holding member. This allows the first buffer to focus solely on vibration damping while the holding member handles the attachment function, simplifying the overall design and enabling tool-free installation through the holding member's inserting portion.
Solution Approach 2:
The holding member acts as an intermediary component between the first buffer and the fan frame. It provides the mechanical connection through its inserting portion passing through the through hole, while the retaining portions (latch member and latch trough) mediate the securing process, eliminating the need for screws or other fastening mechanisms.
3Speed
If rotation speed of air fan is increased, then cooling effect is enhanced, but vibration and noise increase
Solution Approach 1:
The first buffer (damping element) is installed beforehand between the fan frame and the chassis to cushion and absorb vibrations generated by high-speed fan operation. This preemptive damping setup prevents vibration transmission to the chassis, reducing noise while allowing the fan to operate at high speeds for effective cooling.

AI summary
An air fan damping structure is installed on an air fan which has a fan frame. The fan frame has an air inlet, an air outlet and a housing space between them to hold a fan blade assembly. The damping structure includes a first buffer and a holding member located on the fan frame. The first buffer is hollow and has a through hole, and a first anchor portion to form an anchor relationship with a second anchor portion formed on the fan frame. The holding member has an inserting portion to run through the through hole and a depressing portion connecting to the inserting portion to receive a force to allow the inserting portion to run through the through hole. The inserting portion and the through hole have respectively a first retaining portion and a second retaining portion to form a retaining relationship.
