Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If deep learning-based image processing is used to improve diagnostic accuracy, then measurement precision is improved, but processing time increases and productivity decreases

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidprocessing speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the image processing workflow into distinct stages: preprocessing (noise filtering, contrast enhancement), feature extraction (identifying cellular structures, nuclei, cytoplasm), and deep learning-based classification. This segmentation allows critical path operations to be optimized separately, enabling parallel processing of independent stages and reducing overall processing time while maintaining diagnostic accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary actions by pre-processing images before deep learning analysis, including noise reduction, contrast normalization, and preliminary segmentation. These preliminary steps reduce the complexity of the main deep learning task, allowing faster processing while preserving the diagnostic information needed for accurate classification.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If multiple images are captured to improve measurement precision, then diagnostic accuracy is improved, but the time required for observation increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges multiple image capture operations into a single coordinated imaging sequence, where multiple focal planes or angular views are captured in rapid succession without requiring repeated sample preparation or re-positioning. This combining approach maintains the ability to perform multi-image analysis for improved precision while minimizing the total observation time through efficient resource utilization.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 1:

The patent introduces an intermediary layer between conventional image processing and final diagnostic interpretation. This intermediary consists of deep learning models that process extracted features and provide probabilistic classifications, allowing conventional fast processing methods to continue operating while enhancing diagnostic accuracy through the intermediary's pattern recognition capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 1:

The patent implements a universal deep learning framework that can process multiple types of microscopic images (different stains, different magnifications, different sample types) through a single trained model architecture. This multi-functionality reduces device complexity by eliminating the need for separate processing pipelines for different image types, while still achieving high diagnostic accuracy across diverse applications.

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