Solution Overview

Problem

Automatic analysis devices face reduced throughput due to inefficient loading of liquid containers, as different incubation times and reagent usage rates lead to empty positions being filled based on numerical order, resulting in longer transport distances and increased analysis times.

Innovation Solution

The method involves selecting the order of empty receiving positions to minimize movement of the receiving device or transport device, ensuring that the closest empty position is always chosen for loading, whether through rotational or linear movement, to reduce transport distances and optimize the placement of liquid containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If empty receiving positions are filled based on numerical order, then the loading process is simple and systematic, but the transport distance increases and analysis time is prolonged

Engineering Contradiction:
Improveloading process simplicityVSAvoidanalysis time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the receiving device movable rather than stationary. The device can change its position dynamically to bring empty receiving positions closer to the loading position, optimizing transport distance based on which positions are currently empty. This resolves the contradiction by allowing the system to adapt its configuration rather than following a fixed numerical loading sequence.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit preliminarily identifies which receiving positions are empty before the loading process begins. By knowing in advance which positions need to be filled, the system can plan the optimal movement sequence to minimize transport distance, rather than simply loading positions in numerical order.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the receiving device is moved frequently to access different receiving positions, then loading flexibility increases, but mechanical wear and energy consumption increase

Engineering Contradiction:
Improveloading flexibilityVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies partial action by moving the receiving device only partially or only when necessary, rather than continuously repositioning it. The control unit determines the minimal necessary movement to access empty positions, reducing unnecessary mechanical motion. This resolves the contradiction by providing loading flexibility only when needed while minimizing energy consumption from excessive movement.

Inventive Principle:
Principle #16Partial or excessive action

3Device complexity

If receiving positions are arranged in a fixed numerical sequence, then the loading protocol is straightforward, but transport distance to reach empty positions increases

Engineering Contradiction:
Improveloading protocol complexityVSAvoidtransport distance
Core Design Contradiction:
Device complexityVSLength of moving object

Solution Approach 1:

The patent makes the receiving device dynamically reconfigurable in position, allowing it to move to different locations along its transport path. This dynamic capability enables the system to access empty receiving positions with minimal transport distance, regardless of their numerical sequence position. The loading protocol remains straightforward as the control unit automatically manages the optimization.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to an optimized method for successively loading a receiving device (5) with a plurality of liquid containers in an automated analyzer. An automated analyzer (1) comprises a movable receiving device (5) on which a plurality of receiving positions (4) for each liquid container are arranged, a movable transport device for transporting each liquid container, and a control device, wherein the control device is configured to control a method for successively loading the receiving positions (4) arranged on the movable receiving device (5) with liquid containers in the following steps: • Positioning an empty receiving position (4) in a predetermined loading position (30) by repeatedly moving the receiving device (5);• Inserting each liquid container into an empty receiving position (4) located in the assembly position (30) by means of the movable transport device; characterized in that the sequence in which the empty receiving positions (4) are positioned in the assembly position (30) is selected such that the movement of the receiving device (5) for positioning an empty receiving position (4) in the assembly position (30) is always minimal.
