Radiator Fan Buckle Assembly for Dual-Side Secure Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steel wire buckles cannot fix two radiator fans on both sides of a heat sink or liquid cooling radiator, and their functionality is compromised by structural changes in the radiator.
Innovation Solution
A radiator fan fixing buckle device with a first buckle and a second buckle, formed by bending a metal strip, allows for quick fixation of two radiator fans on both sides of a radiator by hooking and locking them together, ensuring they remain secured without external force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional steel wire buckles are used to fix radiator fans, then the fixing process is simple, but the buckles cannot secure two radiator fans on both sides and cannot adapt to structural changes in the radiator
Solution Approach 1:
The buckle device is divided into two separate buckles (first buckle and second buckle) that work together as a system. Each buckle is independently formed from a metal strip and performs a specific function, with the first buckle providing the locking mechanism and the second buckle providing the hooking structure. This segmentation allows each component to be optimized for its specific role while maintaining overall adaptability and reliability.
Solution Approach 2:
The first buckle is nested within the structure formed by the second buckle. Specifically, the first buckle hook is inserted through the second buckle's metal strip, and the first locking portion engages with the second buckle, creating a nested configuration where one buckle is partially contained within the structural framework of the other. This nesting provides both adaptability and secure fixation.
2Reliability
If multiple screws are used to fix radiator fans, then the fixing is secure, but the installation process is complex and time-consuming
Solution Approach 1:
The invention replaces the traditional screw-based mechanical fastening system with a buckle-based system. Instead of using multiple screws that require threading and tightening operations, the device uses elastic metal strip buckles that utilize elastic deformation and mechanical interlocking. The first buckle's locking portion engages with the second buckle's structure, providing secure fixation through elastic retention rather than threaded engagement, significantly simplifying the installation process while maintaining fixing security.
Solution Approach 2:
The buckle device incorporates self-locking and self-retaining features. The first locking portion automatically engages with the second buckle structure when the buckles are assembled, and the elastic properties of the metal strips provide continuous retention force without requiring additional fastening operations. The design allows the buckles to self-adjust and self-secure, eliminating the need for complex installation procedures while ensuring reliable fixation.
3Device complexity
If a single buckle design is used, then the structure is simple, but it cannot prevent separation of the buckles under external force
Solution Approach 1:
The anti-separation function is achieved by dividing the buckle system into two distinct buckles with complementary functions. The first buckle provides the locking mechanism with its locking portion, while the second buckle provides the hooking structure with its open ends. This segmentation allows each buckle to be relatively simple in structure while the combination provides robust anti-separation capability. The first buckle's locking portion engages with the second buckle's metal strip, creating an interlocked configuration that prevents separation without requiring either individual buckle to be complex.

AI summary
A radiator fan fixing buckle device and a radiator fan fixing buckle device assembly structure are disclosed. The radiator fan fixing buckle device includes a first buckle and a second buckle. Each buckle has a vertical strip, and two horizontal strips connected to two ends of the vertical strip. The first buckle has a latching protrusion in the middle of the vertical strip, and the free ends of the horizontal strips are respectively bent into a buckling portion. The fixed ends of the horizontal strips of the second buckle are respectively bent into a hook portion, and the fee ends of the horizontal strips are respectively bent to form a buckling portion. Thereby, the two buckles can fix two cooling fans on the two sides of a radiator, and the two buckles are buckled together and cannot be separated without external force.
