Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual microtomy is used for tissue sectioning, then the process is simple and easy to operate, but the preparation time is excessively long and throughput is low
Solution Approach 1:
The automated tissue sectioning system divides the workflow into distinct modular components: multiple microtomes for parallel sectioning operations, a hydration system for preparing tissue blocks, a transfer mechanism for moving sections to slides, and a control system for coordinating operations. This segmentation enables high throughput while maintaining operational simplicity through automation.
Solution Approach 2:
The system implements continuous processing by hydrating tissue blocks while other blocks are being sectioned, and by transferring sections to slides during active sectioning operations. This eliminates idle time between operations and maintains continuous productive action across all system components.
2Productivity
If multiple microtomes with parallel processing are implemented, then tissue sectioning efficiency increases, but system complexity and device cost increase
Solution Approach 1:
Multiple microtomes are integrated into a single coordinated system sharing common infrastructure including the hydration system, transfer mechanism, and control software. This merging approach enables parallel processing to increase throughput while avoiding the full complexity of completely independent systems.
Solution Approach 2:
The hydration system and transfer mechanism serve multiple microtomes simultaneously, providing universal functionality that reduces overall system complexity. The control system coordinates all microtomes with a single interface, making the complex multi-device system easy to operate as a unified platform.
3Manufacturing precision
If hydration time is extended to improve tissue quality, then sectioning quality improves, but the overall preparation time increases
Solution Approach 1:
Tissue blocks are hydrated in advance during the sectioning of other blocks, so that when a block reaches the microtome, it is already optimally prepared for high-quality sectioning. This preliminary hydration action eliminates waiting time and ensures quality without extending total preparation time.
Solution Approach 2:
The hydration system operates continuously throughout the sectioning process, hydrating blocks in parallel with sectioning operations rather than sequentially. This continuous action maintains sectioning quality while minimizing the time blocks spend in preparation.
4Productivity
If automated transfer of sections to slides is implemented, then manual labor is reduced and throughput increases, but system complexity increases
Solution Approach 1:
The transfer mechanism automatically picks up sections from the microtome blade and places them on slides without human intervention. The system serves itself by coordinating the transfer operation with the sectioning rhythm, reducing manual labor while keeping the transfer mechanism relatively simple through automation.
