Solution Overview

Problem

Existing container storage systems experience uneven wear of components due to biased storage of sample containers, leading to increased maintenance frequency.

Innovation Solution

A container storage apparatus and method that equalizes the use frequency of storage positions by tracking the number of insertions and extractions of containers, using a control unit to determine optimal storage locations based on wear data, and an automatic analysis system that includes a sample container loading and discharging unit, conveyance lines, and an analysis unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large number of sample container storage positions are arranged to store more containers, then the storage capacity is improved, but the wear of components becomes biased to predetermined positions leading to increased maintenance frequency

Engineering Contradiction:
Improvestorage capacityVSAvoidcomponent wear uniformity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system dynamically adjusts container storage positions by tracking the number of insertions and extractions for each case. The control unit assigns containers to cases with lower usage counts, creating a dynamic load-balancing system that prevents any single position from experiencing excessive wear while maintaining high storage capacity.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If containers are stored in biased positions to simplify storage management, then the ease of operation is improved, but the progression of wear of components accelerates

Engineering Contradiction:
Improvestorage management simplicityVSAvoidcomponent lifespan
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The system implements feedback control by continuously monitoring the usage count of each case and using this information to make intelligent assignment decisions. The control unit receives feedback on component wear patterns and adjusts container assignments accordingly, balancing operational simplicity with component longevity through data-driven management.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the same cases are repeatedly used for container storage, then the ease of operation is improved, but the maintenance frequency increases due to component wear

Engineering Contradiction:
Improvestorage consistencyVSAvoidmaintenance frequency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system changes the operational parameters by introducing usage count tracking and adaptive case selection. Instead of using the same cases repeatedly for consistency, the system dynamically selects cases based on their usage history, transforming the storage management approach from static to adaptive while reducing maintenance requirements.

Inventive Principle:
Principle #35Parameter changes

AI summary

There is provided a container storage apparatus that equalizes frequencies of use of a plurality of container storage cases, slows progression of wear of components, and reduces maintenance possibilities. The container storage apparatus includes a case 203 capable of holding and storing a container 201 therein, a storage 9c capable of holding a plurality of cases 203, and a control unit 12 that controls the storage 9c. The control unit 12 includes a number counting unit 121 that acquires, for each of the plurality of cases 203, a first value calculated based on the number of times the container 201 is inserted into the case 203 or the number of times the container 201 is taken out from the case 203, and a determination unit 123 that determines, based on the first value, the case 203 into which the container 201 conveyed from the outside is to be inserted next.
