Innovation Solution
A sliding rail fixing structure that includes a fastening plate, a fastening seat, a clip, elastic members, and sleeves, allowing for tool-free assembly and disassembly of pillars using elastic forces and rotational mechanisms to secure and release the pillars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws and tools are used to fix the sliding rail to the pillar, then the connection strength is improved, but the assembly and disassembly process becomes complex and time-consuming
Solution Approach 1:
The fastening mechanism is segmented into multiple components: a fastening plate with limiting holes, fastening seats, clips with elastic members, and positioning holes. This segmentation allows the complex fastening function to be divided into simpler sub-functions (limiting, fastening, positioning) that can be executed through simple manual operations rather than requiring tools
Solution Approach 2:
The elastic members (springs) provide self-service fastening by automatically engaging with the positioning holes when the clips are inserted. The elastic force enables the clips to snap into place without requiring tools, and the same elastic mechanism allows for easy release by overcoming the elastic force,实现 tool-free assembly and disassembly
2Stability of the object's composition
If screws are used to secure the sliding rail, then the structural stability is improved, but the assembly time increases
Solution Approach 1:
The fastening plate and fastening seats are pre-configured with limiting holes and positioning holes in specific locations. This preliminary arrangement ensures that when the clips are installed, the sliding rail is automatically positioned and secured with stable connection without requiring time-consuming alignment and screw fastening operations
Solution Approach 2:
The traditional screw-based mechanical fastening system is replaced with an elastic snap-fit mechanism. The elastic members provide the necessary fastening force through their elastic deformation, substituting the screw-thread mechanical engagement with a simpler elastic-capture mechanism that achieves both stability and speed
3Reliability
If a traditional screw-based fastening system is used, then the connection reliability is improved, but the operational complexity increases
Solution Approach 1:
The clips act as intermediary components that bridge the fastening plate and the sliding rail. These clips with elastic members serve as mediators that translate simple insertion motion into reliable fastening, eliminating the need for complex screw operations while maintaining connection reliability through the elastic engagement mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and efficient assembly and disassembly of server cabinet pillars without the need for tools, improving operational efficiency and reducing assembly time.
Implementation Method 1
two elastic members (60)... Under the elastic force of the elastic member (60), the two sleeves (50) are extendable out of the two restriction holes (14)
Implementation Method 2
a clip (30)... The two hook portions (34) of the clip (30) pass through the two restriction holes (14)... When the rotation portion (32) rotates around a preset angle, the two hook portions (34) move away from the first pillar (70)

AI summary
A sliding rail fixing structure in a server includes a sliding rail, a fastening plate with a fastening seat, and a clip. The fastening plate defines a restriction hole. The fastening seat includes a supporting member. The supporting member passes through the restriction hole to be positioned at a side of the fastening seat. A size of the supporting member matches a size of an installing hole defined on a pillar. The supporting member is positioned in the installing hole when the pillar is positioned at the side of the fastening seat. The clip can rotate on the fastening seat and includes a hook portion. The hook portion hooks onto the pillar to assemble the pillar to the sliding rail fixing structure. When the clip rotates through a preset angle, the hook portion moves away from the pillar to disassemble the pillar.
