Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing micromanipulation systems for biological samples face challenges in protecting manipulation tools, such as capillaries, from damage during removal and reinstallation, and in preventing user injury, due to mechanical stress and lack of protection mechanisms.
Innovation Solution
A manipulation system with a protective device that can move relative to the tool in a contactless manner, allowing for safe capillary replacement and protection, featuring a clamping member, protective sleeve, and swivel arm mechanisms to ensure tool safety and user safety without mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the manipulation tool is moved from the working area for replacement or cleaning, then the tool can be replaced or maintained, but the tool may be damaged during displacement or the user may be injured
Solution Approach 1:
A protective device is introduced as an intermediary element between the user and the manipulation tool during tool displacement. The protective device can be moved relative to the tool in a contactless manner, providing safety protection without mechanically contacting the fragile tool, thus preventing both tool damage and user injury during tool replacement operations
Solution Approach 2:
The system is divided into functionally independent components: the manipulation tool, the protective device, and the micromanipulation system. This segmentation allows the protective device to operate independently to provide safety without interfering with the tool's manipulation function, enabling tool replacement while maintaining safety protection
2Reliability
If a protective cap is mechanically engaged with the capillary or injection needle, then the protective device can be secured, but mechanical load is exerted on the capillary which could lead to breakage
Solution Approach 1:
The protective device uses a magnetic field as an intermediary force to secure itself to the micromanipulation system without mechanical contact with the capillary. The magnetically coupled protective device can be moved and positioned without exerting mechanical load on the fragile capillary, eliminating the risk of breakage while maintaining secure attachment
Solution Approach 2:
The mechanical engagement system is replaced with a magnetic coupling system. Instead of using mechanical clips, hooks, or clamps that would contact and potentially damage the capillary, the protective device uses magnetic attraction to secure itself to the micromanipulation system, providing security without mechanical stress on the capillary
3Adaptability or versatility
If the manipulation tool is frequently removed and reinstalled, then tool changes can be made, but recalibration is required each time increasing time loss
Solution Approach 1:
The protective device is pre-configured with the micromanipulation system using magnetic coupling, establishing a stable reference frame before tool changes. This preliminary setup allows for quicker tool replacements without requiring full recalibration, as the magnetic reference system remains in place to guide rapid repositioning of new tools
Solution Approach 2:
The magnetic coupling system provides self-aligning properties that automatically guide the manipulation tool to its correct position during replacement. The magnetic field serves as a self-service positioning mechanism that reduces the need for manual recalibration, allowing tool changes without significant time loss

AI summary
A manipulation system for microscope applications comprises a micromanipulation tool and a protective device protecting the tool, wherein the tool and the protective device are movable relative to one another between a position protecting the tool in a contactless manner and a position releasing the tool for the manipulation.
