Microtome Blade Protective Device Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microtomes pose a risk of user injury due to the manual operation of protective devices, which are often not used for convenience, leading to high mechanical stress and difficulty in cleaning the cutting edge safely.
Innovation Solution
Implementing sensors to detect state parameters of the microtome, allowing a control device to automatically control the protective device's position, ensuring it is in a protective position when not in use and facilitating safe sample exchange and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective bracket is manually operated by the user, then the user can control when protection is needed, but the risk of user injury increases due to convenience and lack of time
Solution Approach 1:
The protective bracket is equipped with a sensor that automatically detects when the sample holder is in the replacement position and activates the drive device to move the bracket into the protective position, eliminating the need for manual user intervention and ensuring consistent safety
Solution Approach 2:
The sensor continuously monitors the position of the sample holder and provides feedback to the control device, which automatically adjusts the protective bracket's position based on the detected state, creating a closed-loop safety system
2Reliability
If the protective bracket is automatically moved with each cutting movement, then user safety is improved, but mechanical stress and wear increase due to frequent pivoting
Solution Approach 1:
The protective bracket is moved into the protective position in advance when the sample holder reaches the replacement position, and remains there until needed, avoiding frequent unnecessary movements and reducing mechanical wear
Solution Approach 2:
The protective bracket transitions from static or frequently moving positions to a dynamic system that adapts its position based on real-time detection of sample holder position, moving only when necessary
3Ease of operation
If the sample holder is positioned far from the cutting edge for cleaning, then access to the cutting edge is improved, but the protective bracket remains in the protective position requiring manual intervention
Solution Approach 1:
The sensor detects when the sample holder is positioned for cleaning and automatically activates the drive device to move the protective bracket into the release position, providing feedback-based automatic adaptation to the user's needs

AI summary
This invention relates to a microtome comprising a blade and a sample holder for a sample, wherein the sample holder can be adjusted in relation to the blade, and a protective device for the blade, which can be adjusted between a protective position at least partly covering the blade and an exposure position exposing the blade. Condition parameters of the microtome are detected by means of a sensor and evaluated in a control device. The protective device is assigned a drive device, by means of which the protective device can at least be moved out of the exposure position into the protective position, wherein the drive device can be driven by the control device on the basis of at least one condition parameter of the microtome.
