Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional microtomy for producing tissue sections is a time-consuming manual process, and automating the transfer of cut sections to slides without compromising quality is challenging, especially for rapid sectioning required in clinical settings, and there is a need for efficient storage and follow-on diagnostic capabilities.
Innovation Solution
An automated tape transfer system using a continuous adhesive tape to support tissue sections from a sample block, transferring them to slides, and integrating imaging and storage systems for quality control and data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated microtome sectioning is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The automated sectioning system is divided into distinct functional modules: a microtome unit for cutting sections, a transfer mechanism for moving sections to adhesive tape, and an imaging system for quality control. Each module operates semi-independently, allowing the system to achieve high productivity through coordination of simpler subsystems rather than requiring a single complex automated unit.
Solution Approach 2:
Adhesive tape serves as an intermediary carrier between the microtome blade and the final slide destination. The tape collects multiple tissue sections sequentially during automated cutting, then transports them as a group to the slide station. This intermediary approach simplifies the transfer mechanism compared to direct individual section handling, reducing overall system complexity while maintaining high throughput.
2Productivity
If manual section transfer to slides is performed, then device complexity remains low, but productivity decreases
Solution Approach 1:
Tissue sections are transferred to adhesive tape during the sectioning process itself, before final slide mounting is required. This preliminary transfer creates a buffered intermediate storage system where sections are organized and protected on the tape, enabling batch processing and decoupling the sectioning speed from the slide mounting pace, thereby increasing overall throughput.
Solution Approach 2:
The adhesive tape automatically captures and retains tissue sections through its adhesive properties as they are cut by the microtome. This self-service mechanism eliminates the need for manual picking and handling of each section, allowing continuous automated sectioning without compromising transfer accuracy, thus significantly improving productivity with minimal automation complexity.
3Reliability
If sections are stored on adhesive tape, then storage cost decreases, but reliability of section retention decreases
Solution Approach 1:
The system creates a temporary adhesive copy of the tissue section on the tape during the transfer process. This adhesive copy serves as an intermediate representation that preserves section integrity during transport and storage. The section can later be transferred to the final slide mount, ensuring reliable retention throughout the process while using simple adhesive tape instead of complex storage infrastructure.
