Spring-Loaded Pin for Slide Stainer Power Loss Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide staining systems face challenges in reliability, performance, and cost efficiency, particularly in preventing free-fall during power loss and optimizing agitation phases in the staining process.
Innovation Solution
A slide stainer assembly with a spring-loaded pin to prevent free-fall vertical translation during power loss and a user-interactive slide transporter that can adjust vertical translation and agitation intensity by moving the slide carrier in and out of the staining vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional slide staining system operates without a power loss protection mechanism, then the device complexity is reduced, but the reliability deteriorates due to potential free-fall damage during power outages
Solution Approach 1:
The spring-loaded pin is pre-positioned and spring-loaded to automatically engage with the slide carrier during power loss events, providing protective cushioning against free-fall damage without requiring complex detection or control systems
2Productivity
If automated batch staining is implemented, then productivity increases, but the risk of harmful factors worsens due to potential free-fall damage to slides during power loss
Solution Approach 1:
The spring-loaded pin converts the harmful effect of gravity during power loss into a beneficial cushioning force, where the spring mechanism absorbs impact energy and protects the slides from damage that would otherwise occur during automated operation
3Adaptability or versatility
If fixed agitation parameters are used in automated staining, then the ease of operation improves, but the adaptability deteriorates due to inability to customize agitation intensity
Solution Approach 1:
The system transitions from fixed agitation parameters to dynamic, user-configurable parameters where the height and number of agitation cycles can be customized through the user interface, allowing adaptation to different staining requirements while maintaining automated operation

AI summary
A slide stainer and a method for operating the slide carrier is disclosed. The slide stainer includes a slide carrier that carries one or more laboratory slides; a vessel that is capable of carrying fluid for staining the laboratory slides and that is sized to accommodate the laboratory slides; a slide transporter that moves the slide carrier into and out of the vessel; and a spring loaded pin that engages with a surface of the slide stainer to limit free-fall translation of the slide carrier in an event of a power loss. Additionally, during an agitation phase of a slide staining process, the slide transporter is configured to translate the slide carrier in an upward direction to a pre-determined height that is set by a user of the slide stainer, and the slide transporter translates the slide carrier in a downward direction back into the vessel.
