Screwless Cooling Fan Locking Mechanism for Computer Casings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling fan installation in computer casings requires screws, making assembly and disassembly cumbersome and inconvenient.
Innovation Solution
A cooling fan locking device with a primary housing, side housing, and flexible press plate that uses ventilation holes, positioning slots, and projection parts to latch and lock the fan securely without screws, allowing for quick assembly and disassembly by elastic displacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the fan, then the fan is securely fixed, but the assembly and disassembly process becomes cumbersome and inconvenient
Solution Approach 1:
The fixing mechanism is divided into separate components: a fixing plate with positioning slots and a pressing plate with projection parts. This segmentation allows for quick insertion and locking without requiring screws, resolving the contradiction between secure fixing and ease of assembly/disassembly
Solution Approach 2:
The pressing plate is designed to be elastically deformable, allowing dynamic compression during installation to lock the projection parts into the positioning slots. This elastic deformation enables quick locking without screws while maintaining secure fixing during operation
2Reliability
If screws are used to fix the fan, then the fan remains securely in place, but the time required for assembly and disassembly increases
Solution Approach 1:
The fixing plate and pressing plate are pre-assembled as a unit with the fan, so that during installation only the pressing plate needs to be compressed onto the fixing plate. This preliminary preparation eliminates the need for time-consuming screw fastening operations while maintaining secure fixing
Solution Approach 2:
The elastic deformation of the pressing plate allows for rapid compression and locking of the projection parts into the positioning slots. This dynamic mechanism enables quick assembly and disassembly operations without the time required for screw fastening, while still providing reliable secure fixing

AI summary
A cooling fan device for a computer including a fan device having a primary housing and a side housing. A computer casing a side walls having an area with air permeable holes, right positioning slots, and a left positioning slot. Projection parts of the primary housing are latched into the right positioning slots, and a flange part on a press plate is latched into the left positioning slot, such that the fan device can be quickly assembled on or disassembled from the computer casing without using screws.
