Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Specimen analyzers with small display screens face challenges in accurately conveying analysis results due to low visibility and the risk of users overlooking information, particularly when results need to be displayed with small font sizes or across multiple screens.

Innovation Solution

Incorporating a print unit that prints analysis results on a print sheet, allowing for adjustable print area and preventing the display unit from showing these results, thereby ensuring clear visibility and preventing oversight, even on small screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If analysis results are displayed on a small display screen with small font size, then the display screen can show all results, but the visibility and readability of the results deteriorate

Engineering Contradiction:

Improvecompleteness of analysis results displayVSAvoidvisibility of analysis results

Core Design Contradiction:

Loss of informationVSIllumination intensity

Solution Approach 1:

The patent extracts the analysis results display function from the limited display screen and transfers it to an external printer. The display screen only shows a notification that results have been printed, while the actual detailed results are output to paper with sufficient font size and formatting, eliminating the visibility problem while preserving complete information.

Inventive Principle:

Principle #2Taking out (Extraction)

2Illumination intensity

If analysis results are divided and displayed on multiple screens, then the visibility of individual results improves, but the user may overlook some results

Engineering Contradiction:

Improvevisibility of analysis resultsVSAvoidcompleteness of analysis results recognition

Core Design Contradiction:

Illumination intensityVSLoss of information

Solution Approach 1:

The patent removes the results from the multi-screen display system entirely and outputs them to a printer. This eliminates the problem of users overlooking results on multiple screens, as all results are consolidated on a single printed document that users can easily review without needing to navigate through multiple display pages.

Inventive Principle:

Principle #2Taking out (Extraction)

3Device complexity

If a small display screen is used in a simplified specimen analyzer, then the device complexity is reduced, but the reliability of result communication deteriorates

Engineering Contradiction:

Improvesimplicity of specimen analyzerVSAvoidaccuracy of analysis results communication

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent extracts the high-reliability communication function to the printer, which provides a permanent, readable record of results. The simplified display screen only needs to show basic notifications, maintaining device simplicity while the printer ensures reliable and accurate communication of all analysis results to users.

Inventive Principle:

Principle #2Taking out (Extraction)
