Solution Overview

Problem

Laboratories face challenges during peak times when a large number of sample containers arrive quickly, leading to instrument overload, clogging, and increased workload for personnel, while conventional solutions like additional instruments result in high costs and underutilization.

Innovation Solution

A laboratory automation system comprising a storage unit with a pick-and-place unit, working section, storing section, and transfer unit, which allows sample containers to be stored and processed when laboratory instruments become available, thereby managing peak loads efficiently without the need for additional instruments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If additional laboratory instruments are obtained to handle peak loads, then the laboratory can process more sample containers during peak times, but this results in high costs, space consumption, and underutilization of the additional instruments during non-peak times

Engineering Contradiction:
Improveprocessing capacity during peak timesVSAvoidnumber of laboratory instruments
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The storage unit receives and stores sample containers in advance before they are processed by the laboratory instrument. During peak times, sample containers are accumulated in the storage unit and then processed sequentially as the instrument becomes available, eliminating the need for multiple parallel instruments and avoiding underutilization during non-peak times.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the laboratory processes sample containers at a faster rate, then peak loads can be handled more efficiently, but this may compromise sample quality for samples requiring immediate processing such as centrifugation

Engineering Contradiction:
Improveprocessing speedVSAvoidsample quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Samples requiring immediate processing such as centrifugation are identified and processed as priority tasks. The control unit manages the processing queue to ensure that time-sensitive samples are handled with appropriate urgency while maintaining overall system productivity during peak loads.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If more conveying units are added to handle increased sample flow, then the laboratory can manage peak loads better, but this increases device complexity and space requirements

Engineering Contradiction:
Improvesample container throughputVSAvoidlaboratory space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The storage unit serves as a buffer that accumulates sample containers before they are conveyed to the laboratory instrument. This preliminary storage eliminates the need for multiple parallel conveying units, as samples are processed sequentially from the storage unit as the instrument becomes available, reducing overall space requirements.

Inventive Principle:
Principle #10Preliminary action
