Slide Rail Rack Fastening Member for Chassis Position Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rack systems fail to prevent electronic apparatuses or chassis from being moved out of their predetermined positions, posing an operational challenge.
Innovation Solution
A rack system with a fastening member featuring a blocking portion and an elastic arm, which engages with rack posts to prevent movement by accumulating elastic force and obstructing the path when the apparatus is moved to a specific position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a chassis is mounted on rack posts through slide rails without a fastening mechanism, then the chassis can be easily installed and removed, but the chassis cannot be prevented from being moved from its predetermined position
Solution Approach 1:
The fastening member is designed with an elastic arm that can dynamically change its state between engaged and disengaged positions. The elastic arm automatically engages with the rack post when the chassis is inserted, providing automatic positioning stability, and can be easily disengaged when removal is needed, maintaining ease of operation.
Solution Approach 2:
The elastic arm of the fastening member automatically engages with the rack post through its own elastic deformation when the chassis is inserted into the rack. This self-engaging mechanism provides position stability without requiring additional fastening operations, while still allowing easy removal when the elastic arm is deliberately disengaged.
2Reliability
If a fastening member with blocking portion is added to prevent chassis movement, then position stability is improved, but the device complexity increases
Solution Approach 1:
The fastening member utilizes an elastic arm that functions as a flexible component. This elastic arm can deform to engage and disengage from the rack post, providing position stability through a simple, flexible structure rather than a complex rigid locking mechanism. The elasticity allows the component to absorb movement and maintain engagement automatically.
Solution Approach 2:
The blocking function is extracted as a separate, dedicated fastening member with an elastic arm, rather than integrating it into the chassis or rack structure. This modular approach adds minimal complexity while effectively providing the blocking function to prevent chassis movement from its predetermined position.
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
Effectively prevents the carried object from being moved from its designated position by engaging with rack posts, ensuring stability and maintaining the apparatus in place.
Implementation Method 1
the elastic arm is deflected by an angle and accumulates an elastic force, and the first blocking portion is able to pass over one of the plurality of the posts of the rack. Wherein, when the carried object is located in the second position, the first blocking portion is able to be obstructed on a front side of one of the plurality of posts in response to the elastic force released from the elastic arm

AI summary
A carried object is applied to a rack system. The rack system includes a rack. The rack includes a plurality of posts. The carried object includes a first side wall and a second side wall. Each of the first side wall and the second side wall has a front end portion and a rear end portion. Wherein, an engaging hole is arranged on at least one of the first side wall and the second side wall. A fastening member is arranged at one of the first side wall and the second side wall. The fastening member has a blocking portion extended out of the engaging hole. When the carried object is moved from a first position to a second position, position of a blocking section of the blocking portion of the fastening member is corresponding to one of the plurality of posts of the rack.
