Rack Slide Assembly With Hook Locking Against Chassis Slippage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rack systems lack a mechanism to securely install a chassis to the rack, leading to potential slippage and equipment damage or injury.
Innovation Solution
A slide assembly comprising a first and second rail, a first and second bracket, and an engaging member with a resilient force to maintain the chassis in place, utilizing a hook portion that inserts into an engaging space bounded by the rack posts, preventing the chassis from being pulled out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bracket assembly is used to install a chassis to a rack, then the structure is simple, but the chassis may slip off from the rack easily causing equipment damage or injury
Solution Approach 1:
The installation mechanism is segmented into multiple functional components: a bracket assembly with bracket body and engaging member, a separate resilient member (spring), and a hook portion on the chassis. This segmentation allows each component to perform its specific function while working together to provide secure chassis installation without excessive overall complexity.
Solution Approach 2:
The resilient member (spring) provides automatic engagement force to the engaging member, creating a self-locking mechanism that secures the chassis without requiring additional fastening operations. The spring's elastic force automatically maintains engagement pressure, making the system self-regulating and reliable.
2Reliability
If a secure engagement mechanism is added to prevent chassis slippage, then the chassis security is improved, but the installation and removal operation becomes more complex
Solution Approach 1:
The engaging member is designed to be movable relative to the bracket body, allowing it to dynamically adjust its position during installation and removal. The resilient member provides continuous force to maintain engagement, while the movable design allows easy release when needed, balancing security with operational ease.
Solution Approach 2:
The engaging member acts as an intermediary between the bracket assembly and the chassis hook portion. It translates the simple insertion motion of the chassis into a secure engaged state, and vice versa for removal, simplifying the user's interaction while ensuring reliable security.
3Reliability
If a resilient member is used to maintain engagement force, then the chassis security is improved, but the device complexity increases
Solution Approach 1:
The resilient member (spring) is a passive component that automatically provides engagement force without requiring external power sources, control systems, or additional actuators. It self-regulates the engagement force based on its elastic properties, maintaining reliability while adding minimal complexity.
Solution Approach 2:
The resilient member changes the physical parameter of engagement force dynamically, providing continuous pressure to maintain security. By using a simple elastic element rather than an active control system, the patent achieves force maintenance with minimal added complexity.

Function Achieved in This Case
The slide assembly effectively secures the chassis within the rack, preventing slippage and ensuring safe installation and removal.
Implementation Method 1
A resilient member provides a force to the engaging member to maintain the first fastening portion to be connected to the first post of the rack

AI summary
A slide assembly (12) used for installing a chassis (74) to a rack (10) includes an engaging member (58) which includes a body portion (60), a first fastening portion (62) and a second fastening portion (64). The first and second fastening portions (62, 64) are perpendicularly connected to an end of the body portion (60). The second fastening portion (64) bends and extends from an end of the first fastening portion (62). An engaging space (66) is bounded by the second fastening portion (64) and the rack (10) when the slide assembly (12) is installed to the rack (10). A hook portion (84) of the chassis (74) can be inserted into the engaging space (66) to contact against the second fastening portion (64) so that the chassis (74) is not allowed to be pulled out from the rack (10) when the chassis (74) is installed to the rack (10).
