Solution Overview

Problem

Conventional accommodation apparatuses for freezing targets reduce the storage space due to the need for passages to take out specific units, limiting the quantity that can be stored.

Innovation Solution

An accommodation apparatus with detachable shaft members that allow multiple units to be collectively taken out, eliminating the need for additional space for passage, thereby maximizing storage capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If accommodation units are stored at intervals in the vertical direction to enable selective removal, then ease of operation is improved, but storage space volume is reduced due to required passage space

Engineering Contradiction:
Improveselective removal of accommodation unitsVSAvoidstorage space volume
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The shaft member is divided into multiple coupling portions at different heights, allowing selective coupling to specific accommodation units. This segmentation enables individual or grouped removal without requiring lateral passage space, as the shaft can engage with any desired unit level independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The shaft member serves multiple functions: it acts as both a coupling mechanism for selective removal and a structural support element. By integrating the coupling function into the vertical support structure, the need for separate passage space is eliminated, maximizing storage volume while maintaining operational flexibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If passage space is ensured for taking out lower accommodation units, then ease of operation is improved, but the quantity of freezing targets that can be stored is reduced

Engineering Contradiction:
Improvetaking out of lower accommodation unitsVSAvoidquantity of freezing targets
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

Instead of requiring lateral movement space for removal operations, the invention inverts the approach by using vertical shaft engagement. The shaft member couples to the side or bottom of accommodation units and pulls them vertically upward, eliminating the need for lateral passage space and maximizing the quantity of freezing targets that can be stored.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The shaft member acts as an intermediary mechanism between the user and the accommodation units. By coupling to coupling portions on the accommodation units, the shaft enables selective removal without requiring direct manual access or lateral passage space, thus increasing storage capacity while maintaining ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If dead space is formed for passage movement, then ease of operation is improved, but storage space efficiency is reduced

Engineering Contradiction:
Improvemovement of accommodation unitsVSAvoidstorage space efficiency
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The invention merges the passage function with the structural support function by integrating the shaft member into the storage rack structure. The shaft serves both as a support element and as the removal mechanism, eliminating the need for separate dead space for movement and thereby improving storage space efficiency while maintaining operational ease.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

To increase the quantity of freezing targets stored in a storage space of a freezing container. A first accommodation unit 10 accommodating a first freezing target 91 includes a first female screw member 16a to which a part of a shaft member 80A is detachably coupled. A second accommodation unit 20 accommodating a second freezing target 92 includes a second female screw member 26a to which a part of the shaft member 80A is detachably coupled, and is arranged above the first accommodation unit 10 in a state of being stored in a freezing container 300. In a state where the second accommodation unit 20 is arranged above the first accommodation unit 10, the shaft member 80A is coupled to the first female screw member 16a to take out the first accommodation unit 10 and the second accommodation unit 20 collectively.
