Server Rail Mounting Latch for Screwless Rack Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rail mounting mechanisms for server racks are inconvenient due to the need for screws to secure multiple rails to supports, which complicates assembly and disassembly.
Innovation Solution
A rail mounting mechanism featuring a base with perpendicularly secured supports, a first guide way with a sliding member and latching assembly, and a second guide way with similar components, allowing for secure attachment and easy removal of rails using sliding and latching mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to secure rails to supports, then the connection is strong and reliable, but the assembly and removal process becomes complex and inconvenient
Solution Approach 1:
The mounting mechanism is divided into separate functional components: a mounting piece with positioning holes, a latching assembly with locking members, and resilient members. This segmentation allows the connection to be established through simple alignment and latching operations rather than requiring multiple screw fastening steps, thereby improving assembly convenience while maintaining connection reliability through the dedicated latching function.
Solution Approach 2:
The patent replaces the traditional screw-based mechanical fastening system with a latching system that uses resilient members (springs) to provide locking force. The locking members engage with positioning holes through a latching mechanism that maintains secure connection through elastic force rather than threaded fastening, simplifying the assembly process while ensuring reliable connection.
2Reliability
If multiple screws and fastening components are used, then the connection is secure, but the device complexity increases
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated latching assembly. The locking members, resilient members, and positioning features are combined into one cohesive unit that performs both positioning and securing functions simultaneously, reducing the number of separate components and simplifying the overall mounting mechanism while maintaining secure connection.
Solution Approach 2:
The latching assembly serves multiple functions: it provides positioning through alignment features, secures the connection through locking members, and maintains constant mounting force through resilient members. This multi-functionality eliminates the need for separate positioning and fastening components, reducing device complexity while ensuring reliable mounting.
3Ease of operation
If a simple sliding mechanism is used without latching, then the ease of operation is high, but the connection reliability is insufficient
Solution Approach 1:
The mounting mechanism transitions from a static screw connection to a dynamic latching system that can quickly engage and disengage. The sliding member moves along guide ways to position the locking members, which then dynamically lock into positioning holes to secure the connection. This dynamic approach maintains ease of operation through simple sliding motion while ensuring reliability through the latching engagement.
Solution Approach 2:
The latching assembly acts as an intermediary between the simple sliding motion and the required secure connection. The sliding member provides easy operation, while the latching members translate this motion into secure engagement with the positioning holes, mediating between the simplicity of sliding and the requirement for reliable attachment.

AI summary
A rail mounting mechanism includes a support, a guide way, a sliding member, and a positioning member. The guide way is configured for slidably receiving a rail and includes a guide body and a mounting piece located on the guide body. The mounting piece is detachably engaged with the support. The sliding member is slidably installed on an outer surface of the guide body and includes a sliding body and an arm piece extending from the sliding body. A resilient member is secured to the sliding body and the guide body. The positioning member is secured to an inner surface of the guide body and includes a side flange. The sliding member is slidable between a first position and a second position.
