Storage rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-bay warehouses, the storage of cuboid piece goods, such as standard pallets, often results in inaccurate positioning, leading to potential damage due to violent or uncontrolled storage, as existing rigid stop elements can cause unrestrained horizontal forces that may deform and damage the storage rack's load-bearing components.
Innovation Solution
The storage rack incorporates damping elements that are deformable and flexible, connected to the supports and stop elements via a shaped sheet metal part with specific attachment areas, allowing for force absorption and reducing the risk of damage by permanently deforming under impact, thus preventing deformation and extending the service life of the rack's components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If rigid stop elements are used to prevent deep storage, then positioning accuracy is improved, but the rack becomes vulnerable to damage from violent storage
Solution Approach 1:
The patent applies beforehand cushioning by incorporating energy-absorbing elements (such as deformable metal components or damping materials) into the stop element structure in advance. These elements are designed to deform or absorb energy when subjected to violent storage forces, preventing the transmission of damaging forces to the rack's load-bearing components while still providing the necessary positioning accuracy for normal storage operations.
Solution Approach 2:
The patent applies parameter changes by designing stop elements with variable mechanical properties. The stop elements maintain rigidity under normal storage conditions to ensure positioning accuracy, but are designed to change their mechanical response (through deformation, energy absorption, or controlled failure modes) when subjected to excessive forces from violent storage, thus protecting the rack structure.
2Stability of the object's composition
If stop elements are made stable and rigid, then storage depth control is improved, but horizontal forces from violent storage can damage the rack
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing energy-absorbing elements within the stop element structure. These elements remain dormant during normal operation, providing stable depth control, but activate automatically when subjected to violent storage forces, absorbing energy and preventing damage to the rack's load-bearing components through controlled deformation or damping mechanisms.
Solution Approach 2:
The patent applies the intermediary principle by introducing energy-absorbing elements as mediators between the rigid stop elements and the rack structure. These intermediary components absorb and dissipate the horizontal forces generated by violent storage, preventing the direct transmission of damaging forces to the rack's load-bearing components while maintaining the stop elements' ability to control storage depth.
3Measurement precision
If stop elements are rigidly anchored, then positioning precision is improved, but the rack cannot withstand uncontrolled storage forces
Solution Approach 1:
The patent applies beforehand cushioning by incorporating energy-absorbing elements into the anchoring mechanism of the stop elements. These elements provide rigid anchoring for precise positioning during normal operation but are designed to deform or absorb energy when subjected to uncontrolled storage forces, preventing damage to the rack structure while maintaining positioning precision under normal conditions.
Solution Approach 2:
The patent applies parameter changes by designing the anchoring system with variable stiffness or strength characteristics. The anchoring provides rigid fixation for precise positioning under normal loads, but is designed to change its mechanical response (through controlled deformation, yielding, or energy absorption) when subjected to excessive forces from violent or uncontrolled storage, thus protecting the rack's overall reliability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces the risk of damage to the storage rack and its load-bearing components by absorbing impact forces, ensuring accurate storage and preventing deformation, while allowing for easy replacement of deformed elements, thus enhancing the rack's static stability and extending its service life.
Implementation Method 1
damping elements that are designed to be deformable and flexible in the longitudinal direction of the storage aisle
Implementation Method 2
The cushioning elements are arranged and designed in such a way that they absorb forces that would normally lead to damage to the shelf as deformation by being stretched

AI summary
The invention relates to a storage rack for accommodating cuboid-shaped piece goods such as loaded standard pallets or standard containers, comprising front and rear vertical support elements (1, 4), storage lanes extending over the rack depth, which are provided with at least two horizontal profiled supporting elements (10), which are arranged parallel to each other, in order to provide supports (11) for the piece goods, and stop elements (7) at the ends of the storage lanes facing away from the placement-into-storage and removal-from-storage ends, wherein the stop elements (7) are located at a level above the level of the supports (11). In order to reduce the risk that the rack can be damaged when piece goods are placed into storage too hard in the direction of the rack depth in the case of a storage rack for accommodating cuboid-shaped piece goods such as loaded standard pallets, by means of economical measures that are simple in respect of assembly, the stop elements (7) are fastened to the rear support elements (4) and/or the profiled supporting elements (10) by means of connecting elements (8) that are designed to be deformable in a yielding manner in the longitudinal direction of the storage lanes.
