Adjustable Storage Rack with Sliding Stanchions for Seismic Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage racks are often fixed in size, making them unsuitable for accommodating objects of different sizes, and adjustable racks may compromise on rigidity and durability, failing to meet seismic standards, especially for storing hazardous materials.
Innovation Solution
An adjustable storage rack design featuring stanchions, side rails, and end rails with adjustable assemblies that allow lateral and fore-aft sliding, ensuring flexibility and rigidity while meeting seismic standards through a combination of brackets, fasteners, and engagement members that securely hold the components in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional storage racks are made adjustable, then adaptability to different sized objects is improved, but rigidity and durability deteriorate
Solution Approach 1:
The storage rack employs adjustable stanchions that can be positioned at different locations along the side rails, allowing the rack to dynamically adapt its configuration. The stanchions are secured using clamp assemblies with tie rods that provide rigid fixation once positioned, thus achieving both adaptability and structural strength.
Solution Approach 2:
The rack is divided into modular components including stanchions, side rails, end rails, and clamp assemblies. This segmentation allows individual components to be adjusted and reconfigured independently while maintaining overall structural integrity through standardized connection mechanisms.
2Ease of operation
If adjustable storage racks are designed with sliding mechanisms, then ease of operation is improved, but structural stability deteriorates
Solution Approach 1:
The clamp assemblies incorporate sliding mechanisms that allow stanchions to be easily repositioned along the side rails. Once positioned, the tie rods are tightened to secure the stanchion firmly, transitioning from a mobile to a fixed state that ensures structural stability during seismic events.
Solution Approach 2:
The adjustment mechanism allows change in the position parameter of stanchions along the side rails. The physical state of the connection changes from loose/slidable to tightly secured when the tie rods are tightened, providing both ease of adjustment and structural stability.
3Strength
If conventional storage racks are made fixed in size, then structural integrity is improved, but adaptability to different sized devices deteriorates
Solution Approach 1:
The rack transitions from a fixed configuration to a dynamically adjustable one where stanchions can be repositioned along the side rails. The structural integrity is maintained through robust clamp assemblies and tie rods that securely fix the stanchions in any chosen position.
Solution Approach 2:
The side rails are designed with multiple engagement points along their length, allowing stanchions to be positioned at various locations. This universal design enables the same rack structure to accommodate devices of different sizes and configurations while maintaining structural strength.

AI summary
An adjustable storage rack configured to support a variety of devices, including valve regulated or flooded lead acid batteries. In one embodiment, the adjustable storage rack includes a series of stanchions, a series of side rails extending between at least two of the stanchions, and a series of end rails extending between two of the side rails. The adjustable storage rack may also include a stanchion adjustment assembly slidably coupling one of the stanchions to one of the side rails. The adjustable storage rack may also include first and second end rail adjustment assemblies. The first end rail adjustment assembly slidably couples a first end portion of one of the end rails to one of the side rails, and the second end rail adjustment assembly slidably couples a second end portion of the end rail to a second one of the side rails.
