Solution Overview

Problem

Existing automatic analysis devices with integrated multiple functions require complex and time-consuming preparations when one measuring unit is unavailable, leading to unnecessary work and potential reagent waste due to lack of reflection of unit availability in display systems.

Innovation Solution

An automatic analysis device with a sample disk, reagent disk, and multiple measuring units, featuring a control part that adjusts display based on unit availability, preventing unnecessary preparations by reflecting unit necessity-of-use through a display system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single device integrates multiple measuring units for different analysis types, then device versatility and space utilization are improved, but preparation complexity and time consumption increase due to multiple maintenance, reagent replacement, calibration, and quality control requirements

Engineering Contradiction:
Improvedevice versatilityVSAvoidpreparation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is segmented into multiple independent measuring units (e.g., biochemical analysis unit, immunological analysis unit, hemostatic function unit), each capable of independent operation. The control part divides preparation tasks by measuring unit, allowing operators to focus on specific units without being overwhelmed by all units simultaneously. This segmentation reduces perceived complexity while maintaining overall versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display part dynamically adjusts its content based on the operational status of measuring units. When a unit is unavailable for some reason, the display automatically hides preparation information related to that unit, creating a dynamic interface that adapts to current device state. This dynamic behavior simplifies operator workload by eliminating irrelevant preparation tasks.

Inventive Principle:
Principle #15Dynamics

2Reliability

If preparation operations are required for all measuring units regardless of availability, then system reliability is maintained, but time loss and reagent waste increase due to unnecessary preparations

Engineering Contradiction:
Improvesystem reliabilityVSAvoidtime loss
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control part continuously monitors the availability status of each measuring unit and provides feedback to the display part. Based on this feedback, the display selectively shows or hides preparation information. This feedback mechanism ensures that operators only prepare for available units, eliminating time loss and reagent waste from unnecessary preparations while maintaining reliability through targeted preparation of functional units.

Inventive Principle:
Principle #23Feedback

3Loss of information

If the display shows all preparation information for all measuring units, then complete information is provided, but operator workload increases due to unnecessary preparation tasks

Engineering Contradiction:
Improveinformation completenessVSAvoidoperator workload
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display part applies local quality by selectively presenting information tailored to specific measuring units based on their availability status. For unavailable units, preparation information is hidden; for available units, preparation information is displayed. This localized information presentation maintains completeness for relevant units while reducing overall operator workload by eliminating irrelevant information from the interface.

Inventive Principle:
Principle #3Local quality
