Low-temperature storage system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-temperature storage systems have inefficient space utilization and poor cooling efficiency due to unusable idle spaces during the transfer of storage objects, leading to increased energy consumption.
Innovation Solution
A low-temperature storage system with a rotary storage shelf and a moving mechanism that includes a holding part capable of linear movement, allowing for efficient transfer and orientation of storage racks without intersecting the rotary storage shelf's axis, thereby optimizing space usage and cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tray is oriented to directly face the picking robot during transfer, then the transfer operation can be performed in line with the picking robot and rotation center axis, but unusable idle spaces remain on both sides of the transfer area, resulting in larger installation space and non-optimal space efficiency
Solution Approach 1:
The patent applies asymmetry by positioning the holding part's center axis to be offset from the rotary storage shelf's rotation center axis. This asymmetric arrangement allows the moving mechanism to be disposed closer to one side of the transfer area, eliminating unusable idle spaces on both sides and improving space efficiency while maintaining transfer functionality.
2Ease of operation
If unusable idle spaces are present in the transfer area, then the picking robot can be positioned in line with the transfer area, but cooling efficiency deteriorates and energy consumption increases
Solution Approach 1:
By offsetting the holding part's center axis from the rotary storage shelf's rotation center axis, the patent eliminates unusable idle spaces in the transfer area. This asymmetric configuration improves cooling efficiency by removing air stagnation zones and reduces the energy consumption required for cooling the storage chamber.

AI summary
To provide a low-temperature storage system that can reduce unusable idle spaces to improve space efficiency for storing storage objects and to prevent a drop in cooling efficiency with simple structure. The low-temperature storage system includes a low-temperature storage chamber accommodating a rotary storage shelf, a moving mechanism having a holding part to carry a storage rack thereon for loading and unloading a storage object in the storage rack, and a picking stage. The holding part is located such that its center axis along a direction of its back and forth movement does not intersect a rotating shaft of the rotary storage shelf. The rotary storage shelf stores the storage rack such that the storage rack, when brought to a removal position, is oriented in a same direction as that of a storage rack placed on the picking stage.
