Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If digital images are stored in PACS or VNA for archiving, then storage and backup capabilities are improved, but integration with modern pathology workflows becomes challenging
Solution Approach 1:
The patent introduces a workflow server as an intermediary component that mediates between the PACS/VNA storage system and the pathology workflow systems. The workflow server receives workflow information from external systems, manages image analysis tasks, and coordinates between different components without requiring direct integration between PACS and workflow systems, thus maintaining storage capabilities while improving workflow adaptability
Solution Approach 2:
The system is divided into separate functional modules: image receiving unit, image analysis unit, image evaluation unit, assembly and unification unit, and workflow server. This segmentation allows each module to operate independently with well-defined interfaces, enabling the PACS storage system to maintain its archiving function while the workflow server handles workflow integration, resolving the contradiction between storage capability and workflow adaptability
2Quantity of substance
If images are accessed through a gateway from workstations, then centralized storage is achieved, but processing speed and data availability are reduced
Solution Approach 1:
The system performs preliminary actions by pre-processing images through automatic analysis (tumor cell detection, biomarker quantification, pattern recognition) and quality testing before final archiving. The workflow server pre-coordinates analysis tasks and prepares images in advance, reducing the need for complex gateway operations and improving subsequent access speed
Solution Approach 2:
The patent replaces the traditional mechanical gateway-based access system with a workflow server that uses standardized interfaces and automated task coordination. The workflow server directly manages image flow between storage and analysis units, eliminating the bottleneck of gateway-mediated access while maintaining centralized storage architecture
3Quantity of substance
If multiple devices are used in PACS system, then storage and access capabilities are improved, but device complexity increases
Solution Approach 1:
The workflow server is designed as a universal multi-functional component that handles multiple tasks: receiving workflow information, managing image analysis tasks, coordinating between units, and interfacing with external systems. This multi-functionality consolidates what would otherwise require multiple specialized devices, reducing system complexity while maintaining enhanced storage and access capabilities
