1Extent of automation

If multiple processing modules are combined to automate the entire sample processing workflow, then the extent of automation is improved, but the device complexity increases due to unclear module arrangement and conveyance handling

Engineering Contradiction:
Improveautomation of sample processingVSAvoidmodule arrangement complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The automatic processing system is divided into distinct functional modules: a staining module for staining processing, a post-processing module for dehydration/sealing processing, and a conveyance module for transporting slide glasses. Each module has a dedicated function, and the conveyance module includes separate conveyance paths (first conveyance path for staining samples, second conveyance path for post-processing samples) to handle different workflow types independently, reducing operational complexity while maintaining high automation.

Inventive Principle:
Principle #1Segmentation

2Productivity

If separate conveyance paths are provided for different processing workflows, then the productivity is improved by reducing time loss, but the device complexity increases due to additional conveyance structures

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidconveyance structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The conveyance module provides different conveyance paths tailored to specific processing needs: a first conveyance path for samples requiring staining processing and a second conveyance path for samples requiring only post-processing. This localized optimization allows samples to take the appropriate path based on their processing requirements, eliminating unnecessary steps and reducing time loss while maintaining manageable system complexity through modular design.

Inventive Principle:
Principle #3Local quality

3Productivity

If the staining unit and post-processing unit are disposed with the loading and collection unit in between, then the productivity is improved by optimizing workflow, but the device complexity increases due to non-linear arrangement

Engineering Contradiction:
Improveoverall process efficiencyVSAvoidmodule disposition complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system employs a dynamic module disposition where the loading and collection unit is strategically positioned between the staining unit and post-processing unit. This arrangement allows the conveyance module to flexibly route samples through different paths: samples can be conveyed from the loading unit to the staining unit, then to post-processing, or directly from the loading unit to post-processing. This dynamic configuration optimizes workflow efficiency by eliminating unnecessary conveyance steps while maintaining clear module functions.

Inventive Principle:
Principle #15Dynamics
