Integrated Pathology Marking for Cassette-Slide Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking technologies for tissue cassettes and glass slides in pathology are separate, leading to increased chances of information errors and misdiagnosis due to non-uniform or missing markings during the transfer of information between different stages.
Innovation Solution
A marking all-in-one machine that integrates simultaneous marking of tissue cassettes and glass slides using a first and second feeding unit, each with a feeding chute and mechanism, and a centralized printing unit with a laser generator, ensuring accurate and efficient marking in a unified process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate marking equipment is used for tissue cassettes and glass slides, then different marking operations can be performed independently, but information recording errors increase due to non-uniform marking and manual information transfer
Solution Approach 1:
The patent combines two separate marking operations (tissue cassette marking and glass slide marking) into a single integrated marking device. The device uses one laser marking unit that can simultaneously or sequentially mark both tissue cassettes and glass slides, eliminating the need for separate marking equipment and manual information transfer between operations.
Solution Approach 2:
The marking device is designed with universal functionality to perform multiple marking tasks using a single system. The laser marking unit can adapt to mark different objects (tissue cassettes and glass slides) with different marking requirements,实现one device performing what previously required two separate devices.
2Adaptability or versatility
If manual information transfer is used between marking stages, then flexibility in handling different information is maintained, but time consumption increases and information errors occur
Solution Approach 1:
The device uses optical copying technology where the marking information for glass slides is automatically copied from the tissue cassette marking information. The laser marking unit reads the barcode or QR code on the tissue cassette, retrieves the corresponding glass slide information, and automatically marks the glass slide with the copied information, eliminating manual information transfer.
Solution Approach 2:
The patent replaces the manual mechanical information transfer process with an automated optical and electronic information system. Instead of manually reading and rewriting information, the system uses barcode/QR code scanning, computer memory, and laser marking to automatically transfer and record information, substituting mechanical manual operations with automated electronic systems.
3Ease of manufacture
If separate marking processes are used for tissue cassettes and glass slides, then each marking can be optimized independently, but the overall marking efficiency decreases due to sequential processing
Solution Approach 1:
The integrated marking device enables continuous marking operations where tissue cassettes and glass slides are marked in a continuous workflow without interruption. The device can mark multiple items sequentially or simultaneously without requiring setup changes or manual intervention between different marking tasks, maintaining continuous productive action throughout the marking process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

AI summary
Disclosed is a marking all-in-one machine. The marking all-in-one machine comprises a first feeding unit, a second feeding unit and a printing unit. A first feeding mechanism is configured to transport tissue cassettes stored in a first feeding chute to a first printing position. A second feeding mechanism is configured to transport glass slides stored in a second feeding chute to the first printing position. The printing unit is configured to simultaneously carry out marking on the tissue cassettes and the glass slides. The first feeding unit and the second feeding unit are simultaneously arranged to simultaneously carry out marking on the tissue cassettes and the glass slides which are in one-to-one correspondence, and the problems of non-uniform marking, missing marking and the like are avoided, so that the accuracy of information recording is improved, and the work efficiency of marking is improved at the same time.
