Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multicomponent medical raw data is compressed using conventional methods, then data transmission and storage efficiency is improved, but compression speed and decoding efficiency deteriorate due to the large amount of data

Engineering Contradiction:
Improvedata volumeVSAvoidcompression speed
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent segments the multicomponent medical raw data into multiple independent component datasets (e.g., bone, soft tissue, air components in CT; different receiver channels in MRI). Each component dataset is compressed separately using conventional compression methods, rather than compressing all components together as a single large dataset. This segmentation enables parallel processing of multiple smaller datasets, significantly improving compression speed while achieving efficient overall compression ratios.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multicomponent medical raw data is compressed using conventional methods, then data transmission and storage efficiency is improved, but decoding efficiency deteriorates

Engineering Contradiction:
Improvedata volumeVSAvoiddecoding time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The decoded compressed data is organized into separate component datasets corresponding to different anatomical or functional components. Each component dataset is decoded independently and then synthesized to reconstruct the complete medical image or dataset. This segmented approach reduces the computational complexity of decoding by avoiding the need to process the entire multicomponent dataset simultaneously, thereby improving decoding efficiency.

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If conventional compression methods are applied to multicomponent medical data, then storage efficiency is improved, but data processing complexity increases

Engineering Contradiction:
Improvestorage capacityVSAvoidprocessing complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent divides the complex multicomponent medical data into multiple simpler component datasets that can be processed using standard compression algorithms. Each component is identified and separated based on its unique characteristics (e.g., density ranges in CT, signal frequencies in MRI), allowing the use of optimized compression parameters for each component type. This approach reduces overall processing complexity while achieving superior storage efficiency compared to treating all data uniformly.

Inventive Principle:
Principle #1Segmentation

4Loss of information

If large amounts of multicomponent medical raw data are transmitted, then data completeness is improved, but transmission speed deteriorates

Engineering Contradiction:
Improvedata completenessVSAvoidtransmission speed
Core Design Contradiction:

Solution Approach 1:

The patent compresses multicomponent medical raw data by segmenting it into multiple component datasets, applying compression algorithms to each component separately. This reduces the overall data volume while preserving the integrity and completeness of all medical information. The compressed component datasets can then be transmitted more efficiently, achieving both fast transmission speeds and complete data transfer.

Inventive Principle:
Principle #1Segmentation
