Intermediate Storage Tower for Piece Goods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intermediate stores for piece goods are structurally complex and difficult to access for loading and unloading, requiring complex devices to adjust height and position for efficient storage and retrieval.
Innovation Solution
A compact intermediate store design featuring vertically adjustable storage discs within a central tube, where the discs move up and down along a groove without altering the tube's position, allowing for stable and accessible loading and unloading at a constant height, using a lifting unit and rotation mechanism integrated into the tube, with a lifting bearing and rotary bearing for guided movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire intermediate store device is moved up and down for height adjustment, then the storage discs can reach different heights, but the structural complexity increases and stability decreases
Solution Approach 1:
The patent divides the height adjustment function into two independent parts: the central tube remains fixed while only the storage discs are moved vertically. This segmentation allows height adjustment without moving the entire device, reducing structural complexity and improving stability.
Solution Approach 2:
The patent introduces bearing journals as intermediary elements that enable vertical movement of storage discs along the fixed central tube. These bearing journals act as mediators between the storage discs and the tube, allowing height adjustment through a simpler mechanism than moving the entire device.
2Adaptability or versatility
If the entire intermediate store device is moved up and down for height adjustment, then the storage discs can reach different heights, but the overall stability of the arrangement decreases
Solution Approach 1:
By segmenting the device into a fixed central tube and movable storage discs, the patent maintains the stability of the main structure (tube) while allowing height adjustment of the storage discs. This segmentation prevents the entire arrangement from becoming unstable during adjustment.
3Adaptability or versatility
If complex lifting and guiding devices are used for height adjustment, then the storage discs can be positioned at different heights, but the device complexity increases
Solution Approach 1:
The bearing journals serve as simple intermediary elements that enable vertical movement without requiring complex lifting and guiding devices. The journals fit into grooves in the central tube, providing a straightforward mechanism for height adjustment.
Solution Approach 2:
The storage discs with integrated bearing journals can move vertically along the grooves of the central tube through their own weight and simple gravitational action, without requiring complex external lifting mechanisms. The system uses its own structure to enable the movement.
4Stability of the object's composition
If the storage tower is surrounded by prismatic cladding with guide elements, then the storage tower can be guided during lifting, but the accessibility for unloading decreases
Solution Approach 1:
The patent removes the surrounding prismatic cladding and guide elements, keeping only the essential groove structure in the central tube. This segmentation eliminates unnecessary structural elements that hinder accessibility while maintaining the guidance function through the simpler groove-bearing journal mechanism.
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 solution simplifies the loading and unloading process by maintaining a constant overall height and stability, reducing the need for complex external adjustments and ensuring easy accessibility, while maintaining structural stability and compactness.
Implementation Method 1
a lifting unit (35) which is arranged in the tube (2) and is connected to the bearing journal (12) in such a way that the bearing journal (12) can be moved vertically within the groove area (29) of the pipe (2) by driving the lifting unit (35)
Implementation Method 2
the ends of the bearing journals (12) are connected to the storage disks (28) in such a way that the storage disks (28) can be moved up and down vertically with the bearing journal (12)
Implementation Method 3
a lifting bearing (13) is provided, which surrounds the bearing pin (12) in the slots of the groove in the manner of a ring. Such support of the journal in the groove has the effect of preventing rubbing against the inner walls of the groove in the tube.
Implementation Method 4
a rotation unit (17) is arranged on the ends of the bearing journal (12) protruding from the tube (2), via which the storage disks (28) are connected to the bearing journal (12) so that they can rotate horizontally

AI summary
The invention relates to an intermediate storage unit for general cargo comprising a storage tower with several circular or polygonal horizontal storage disks 28 arranged vertically one above the other and spaced apart from each other, and mounted on a central tube 2. This intermediate storage unit is made more compact and simpler by the fact that the storage disks 28 are fixedly connected to one another and vertically displaceable on the tube 2, that a groove 29 is formed in a groove area along the length of the tube 2, such that the wall of the tube 2 has vertical slots on two sides of the tube in the groove area, that a bearing pin 12 corresponding to the shape of the groove is inserted horizontally into the tube 2 such that one end of the bearing pin 12 projects horizontally out of the tube 2 through one of the slots, and that a lifting unit is arranged in the tube 2 which is connected to the bearing pin 12 in such a way thatthat the bearing pin 12 within the groove area of the tube 2 is vertically movable by driving the lifting unit via a lifting drive device, and that the ends of the bearing pin 12 are connected to the storage disks 28 in such a way that the storage disks 28 are vertically movable up and down with the bearing pin 12.
