Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the area in which there is the sample is estimated only on the basis of the position of the cell nucleus, then the specification process is simple, but the accuracy of specifying the analysis area is insufficient

Engineering Contradiction:
Improvespecification process complexityVSAvoidanalysis area specification accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent introduces a second fluorescent substance as an intermediary marker in the solution to define the boundary of the analysis area. This intermediary element mediates between the simple specification process and accurate area definition, allowing the system to achieve high precision without excessive complexity by using the second fluorescent substance as a reference framework

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter basis for area specification from solely nuclear position coordinates to a dual-parameter system combining nuclear position with the spatial distribution of the second fluorescent substance. This parameter transformation enables more accurate analysis area definition by incorporating additional spatial information from the fluorescent solution distribution

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If dual fluorescent substances and lights are used to generate and process images for precise area specification, then the analysis accuracy is improved, but the device complexity increases

Engineering Contradiction:
Improvesample analysis accuracyVSAvoiddual fluorescent system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent makes the imaging system universal by enabling it to capture and process multiple fluorescent signals (first and second fluorescent substances) through the same optical path and imaging device. This multi-functionality allows the system to achieve high analysis accuracy by utilizing both fluorescent markers without requiring separate specialized devices for each, thereby managing complexity through resource sharing

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the detection of two different fluorescent substances into a unified imaging and processing workflow. By combining the optical paths, imaging devices, and analysis procedures for both fluorescent markers into an integrated system, the patent achieves high measurement precision while controlling device complexity through consolidation rather than multiplication of components

Inventive Principle:
Principle #5Merging (Combining)
