Low-temperature storage system for samples
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cryopreservation equipment requires a large space for lifting mechanisms, making it inconvenient to extract samples, especially in large storage systems, leading to reduced work efficiency.
Innovation Solution
A sample cryogenic storage system with a lifting well assembly, rotary gripping assembly, shovel plate assembly, and cover opening assembly that allows for efficient access and manipulation of samples within a compact storage chamber, including a movable lifting well, 360-degree rotary gripping, and automated cover handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed lifting well mechanism is used to extract lifting baskets from storage equipment, then sample extraction can be performed, but a large space is occupied and the mechanism becomes less convenient
Solution Approach 1:
The lifting well assembly is designed to be movable rather than fixed, allowing it to dynamically reposition itself along the inner wall of the storage chamber. This dynamic positioning capability enables the mechanism to access different storage ports without requiring a large fixed structure, thereby improving operational convenience while reducing space occupation.
Solution Approach 2:
The lifting well assembly moves along the inner wall of the storage chamber in a dimensional space that is separate from the vertical lifting motion. This separation of motion dimensions allows the mechanism to reach multiple storage ports without increasing the footprint area, effectively solving the space-convenience contradiction.
2Quantity of substance
If a large storage range refrigerator is used to store more samples, then storage capacity increases, but it becomes inconvenient to extract the lifting basket and work efficiency is reduced
Solution Approach 1:
The storage chamber is divided into multiple independent storage ports, each accessible by the movable lifting well assembly. This segmentation allows the system to maintain large storage capacity while enabling selective access to individual baskets without requiring the entire system to be accessed, thereby improving work efficiency.
Solution Approach 2:
The movable lifting well assembly acts as an intermediary mechanism that bridges the storage chambers and the operation chamber. It enables efficient transfer of lifting baskets between storage locations and the operation area, maintaining high productivity even as storage capacity increases.
3Ease of operation
If multiple lifting mechanisms are disposed above storage equipment to extract lifting baskets, then sample access is enabled, but a large space is occupied
Solution Approach 1:
The movable lifting well assembly serves multiple functions: it can access different storage ports, lift different lifting baskets, and transfer them to the operation chamber. This multi-functionality eliminates the need for separate lifting mechanisms at each storage port, significantly reducing the total volume occupied by lifting equipment while maintaining full sample access capability.

AI summary
The present invention discloses a sample cryogenic storage system, including an operation chamber and a storage chamber, where the operation chamber is disposed above the storage chamber and may perform an access operation on a sample stored in the storage chamber; a plurality of storage ports are disposed in an upper end surface of the storage chamber; and a lifting well assembly is disposed in the operation chamber, is movably disposed in the operation chamber, and is movable to the corresponding storage ports to lift a lifting basket in the storage chamber. The present invention has the following beneficial effects: the lifting well assembly lifts the lifting basket in the operation chamber, a shovel plate assembly may push out a plate rack of the lifting basket, a rotary gripping assembly may rotate at 360 degrees to grip the plate rack or the sample, a jacking-up mechanism may jack up a transfer tank and dock the transfer tank with the operation chamber, and the rotary gripping assembly may store the sample or the plate rack from the transfer tank into the lifting basket through the shovel plate assembly and the lifting well assembly, so as to store the lifting basket in the storage chamber, thereby greatly improving the work efficiency.
