Solution Overview
Problem
Storage racks for cuboid-shaped piece goods, such as loaded standard pallets, face damage risks due to insufficient support and positioning inaccuracies, leading to potential falls and structural damage from forceful placement.
Innovation Solution
The integration of deformable connecting elements between stop elements and support elements, which absorb impact forces through plastic deformation, reducing the risk of damage and providing stable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rigid stop elements are used to prevent piece goods from being placed too far into storage, then positioning accuracy is improved, but the rack becomes vulnerable to damage from forceful placement
Solution Approach 1:
The patent applies beforehand cushioning by introducing deformable connecting elements that can absorb impact forces before they reach the support elements. These connecting elements are designed to yield under excessive force, cushioning the blow and preventing damage to the rack structure while still maintaining positioning accuracy during normal operation.
Solution Approach 2:
The patent changes the mechanical parameter of the connecting elements from rigid to deformable. This parameter change allows the stop elements to maintain their positioning function while acquiring the ability to absorb impact energy through controlled deformation, thus resolving the contradiction between positioning accuracy and damage resistance.
2Productivity
If piece goods are placed automatically with high speed, then productivity is improved, but positioning accuracy deteriorates leading to forceful placement
Solution Approach 1:
The deformable connecting elements serve as a cushioning mechanism that compensates for positioning inaccuracies inherent in high-speed automatic placement. By allowing controlled deformation during forceful placement, the system can maintain high productivity without sacrificing reliability, as the cushioning elements prevent damage from occasional misplaced goods.
3Manufacturing precision
If stop elements are located above the support level to prevent over-placement, then positioning accuracy is improved, but impact forces increase when goods are placed forcefully
Solution Approach 1:
The deformable connecting elements act as an intermediary between the stop elements and the support elements. They transmit the positioning function of the stop elements while simultaneously absorbing and reducing impact forces through their deformable nature, thus mediating between the need for accurate positioning and the need to minimize impact forces.
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
The deformable connecting elements effectively absorb and dissipate forces that could cause damage, ensuring the structural integrity of the storage rack and reducing mechanical stress, thereby preventing falls and maintaining the rack's stability during forceful placement.
Implementation Method 1
connecting elements which are designed to be deformable in a yielding manner in the longitudinal direction of the storage lanes
Implementation Method 2
The damping elements are thus arranged and configured so that through deformation and stretching they absorb the forces which could normally lead to damage to the rack

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.
