Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual input of processing protocols is used for each tissue sample, then flexibility in processing different sample types is maintained, but error rate increases and time consumption increases

Engineering Contradiction:

Improveprocessing flexibilityVSAvoiderror rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system automatically retrieves processing protocols from LIS/LIMS using sample identifiers (barcodes) without requiring manual intervention. The automated tissue processing system queries the LIMS, receives protocol data, and implements it autonomously, eliminating human error while maintaining adaptability through protocol diversity in the database

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system establishes bidirectional communication between the tissue processing system and LIMS/LIS. Processing status updates are automatically communicated back to the LIMS, creating a feedback loop that ensures data accuracy and enables real-time tracking without manual verification

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If manual input of processing protocols is used for each tissue sample, then protocol customization is possible, but productivity decreases due to tremendous time and effort required

Engineering Contradiction:

Improveprotocol customizationVSAvoidprocessing throughput

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Processing protocols are pre-stored in the LIMS/LIS database with all necessary parameters and specifications. When a sample is introduced, the system automatically retrieves the appropriate pre-defined protocol, eliminating the need for manual protocol creation or configuration for each sample while maintaining full customization capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The automated system serves multiple functions: it identifies samples via barcode, queries the LIMS for protocols, controls tissue processing parameters, and communicates status updates. This multi-functional integration replaces multiple manual operations with a single automated workflow, dramatically increasing productivity

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If automated tissue processing system operates without LIMS integration, then device simplicity is maintained, but information accuracy decreases and workflow automation is limited

Engineering Contradiction:

Improvesystem simplicityVSAvoiddata accuracy

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The LIMS/LIS serves as an intermediary between the automated tissue processing system and the laboratory information ecosystem. It stores, manages, and transmits protocol data and sample information, acting as a centralized database that connects processing equipment with laboratory workflows without requiring complex direct integration between multiple devices

Inventive Principle:

Principle #24Intermediary (Mediator)

4Measurement precision

If real-time communication with LIMS is implemented, then workflow tracking accuracy is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements automated feedback communication where processing status updates are automatically transmitted to the LIMS at key workflow stages. This real-time feedback mechanism provides accurate workflow tracking without requiring complex manual data entry or verification systems

Inventive Principle:

Principle #23Feedback

AI summary

Systems and methods enable fully automated tissue processing using tissue processing components for producing tissue sections from a tissue sample block and to transfer the tissue sections to slides. A control device queries a Laboratory Information Management System (LIMS) with a sample identifier associated with the tissue sample block and receives tissue sample data from the LIMS. The control device generates tissue processing workflow parameters based on the tissue sample data for each tissue processing component to perform an automated tissue processing workflow. The control device automatically controls each tissue processing component according to the tissue processing workflow parameters to process the tissue sample block. The control device generates a block processing update message while the tissue sample block is processed and communicates the block processing update message to the LIMS to enable the LIMS to track the automated tissue processing workflow for the tissue sample block.
