Rack Rail Catch Mechanism for Serviceable Equipment Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current racking systems for equipment, such as computer servers and audio/video devices, face challenges in providing both space efficiency and in-rack serviceability, as rail-mounted systems are not serviceable and slides require additional horizontal space, leading to potential equipment tipping and damage.
Innovation Solution
A racking system featuring a rail with a catch mechanism that moves between engaged and disengaged positions, allowing for partial equipment removal while preventing tipping, includes a latch and slot configuration with various positions to ensure secure attachment and stable positioning within the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If slides are used to enable partial equipment removal, then in-rack serviceability is improved, but horizontal space consumption increases
Solution Approach 1:
The patent transitions from horizontal space consumption (slides) to vertical space utilization (rails with L-shaped cross-section). The rail system uses the vertical dimension for support while minimizing horizontal footprint, allowing equipment to be partially removed vertically without requiring additional horizontal space within the rack.
Solution Approach 2:
The rail system incorporates a dynamic catch mechanism that can be moved between engaged and disengaged positions. This dynamic element allows the rail to transition from a fixed support structure to one that permits controlled partial removal of equipment, enabling serviceability without requiring the static horizontal space of slides.
2Area of stationary object
If rails are used for space efficiency, then horizontal space consumption is reduced, but in-rack serviceability deteriorates due to equipment tipping risk
Solution Approach 1:
The catch mechanism serves as an intermediary element between the rail and equipment housing. It provides the necessary support and restraint to prevent tipping during partial removal, acting as a mediator that enables serviceability while maintaining the space-efficient rail configuration. The catch can be engaged to prevent tipping or disengaged to allow removal as needed.
Solution Approach 2:
The system changes the support parameter from single-direction (traditional rail) to multi-directional by incorporating the catch mechanism. The catch can engage in different positions and orientations, providing support forces in multiple directions to prevent tipping while maintaining the compact horizontal footprint of the rail system.
3Ease of repair
If equipment is partially removed from rail for servicing, then in-rack serviceability is improved, but equipment stability deteriorates causing potential tipping
Solution Approach 1:
The catch mechanism provides preliminary anti-action by being positioned to counteract the tipping force before it can cause damage. When engaged, the catch preemptively restrains the equipment from rotating or tipping during partial removal, preventing the harmful effect before it occurs.
Solution Approach 2:
The catch acts as an intermediary support element that maintains equipment stability during partial removal. It provides the necessary counterbalancing force to prevent tipping while allowing the equipment to be sufficiently removed for servicing, mediating between the need for serviceability and the need for stability.

AI summary
A racking system for storing equipment in a rack includes a rail that is configured to be attached to the rack and a housing that receives the equipment. One of the housing and rail includes a catch, and the other of the housing and the rail includes a slot for engaging the catch. The catch is movable between a first position and a second position. In the first position, the catch engages the slot and extends away from a surface of either the housing and the rail, and in the second position, the catch is withdrawn from engaging the slot. The catch rotates upon moving between the first position and the second position, and the catch is biased towards the first position.
