Solution Overview

Problem

Existing sample analyzing systems face challenges in efficiently handling and capping secondary tubes due to variations in cap types and handling requirements across different stations, leading to inefficiencies and increased costs.

Innovation Solution

A sample analyzing system with a cap selection module that selects appropriate cap types (uncapped, first cap type, or second cap type) for secondary tubes based on scheduled stations and processes, optimizing handling and compliance with regulations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single cap type is applied to all secondary tubes, then the capping process is simple and fast, but it cannot meet the different requirements of various stations and regulations

Engineering Contradiction:
Improveadaptability to different station requirementsVSAvoidcapping system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The capping system is made dynamic by allowing the cap type to be selected and changed based on the destination station and regulatory requirements. The cap selection module dynamically determines which cap type (first or second) to apply to each secondary tube, enabling the system to adapt to different requirements without being fixed to a single cap type configuration

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The capping function is segmented into multiple cap types (first cap type and second cap type) with different characteristics. Each cap type is suited for specific station requirements or transportation regulations. The system divides the single capping function into multiple specialized capping options that can be selectively applied

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple cap types are used for different stations, then specific station requirements are met, but the handling process becomes more complex and time-consuming

Engineering Contradiction:
Improvecompliance with station requirementsVSAvoidcapping process efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The cap type is selected in advance based on the predetermined destination station and regulatory requirements before the capping process begins. The cap selection module determines the appropriate cap type beforehand, allowing the actual capping operation to proceed quickly without delays caused by on-the-spot decision-making or trial-and-error approaches

Inventive Principle:
Principle #10Preliminary action

3Reliability

If caps are applied to all secondary tubes, then transportation regulations are met, but unnecessary caps increase handling complexity and cost

Engineering Contradiction:
Improvecompliance with transportation regulationsVSAvoidhandling process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of uniformly applying caps to all secondary tubes, the system applies caps selectively based on local requirements of each destination station and regulatory constraints. The cap selection module determines which specific secondary tubes require capping and which cap type should be applied, ensuring that caps are only added where necessary for compliance or operational requirements

Inventive Principle:
Principle #3Local quality

AI summary

A sample analyzing system (1) for analyzing a sample contained within a primary tube entering the sample analyzing system (1) comprises a plurality of stations (11, 12, 13, 14, 15) for analyzing samples and/or for storing samples and/or for transporting samples to an offline analyzer. An aliquoter station (3) is configured to, depending on which tests are scheduled for the sample within the primary tube, fill a share of the sample contained in the primary tube into at least one secondary tube, wherein the secondary tube is scheduled for being sent to at least one selected station (11, 12, 13, 14, 15) from the plurality of stations (11, 12, 13, 14, 15). A first cap station (4a) is configured to apply a cap of a first cap type to the secondary tube. A second cap station (4b) is configured to apply a cap of a second cap type to the secondary tube, wherein the second cap type differs from the first cap type. A cap selection module (6) is configured to select a capping selection for the secondary tube, wherein capping selections include one or more of an uncapped state, a first cap state, wherein the secondary tube is closed by a cap of the first cap type, and a second cap state, wherein the secondary tube is closed by a cap of the second cap type. Therein, the sample analyzing system (1) is further configured to, depending on the selected capping selection, provide the secondary tube with a cap of the first cap type at the first cap station if the first cap state is selected, or with a cap of the secondary cap type at the second cap station if the second cap state is selected, or leave the secondary tube uncapped if the uncapped state is selected, before the secondary tube is send to its at least one selected station (11, 12, 13, 14, 15).
