Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for organizing and automatically handling microscope slides are inefficient in transferring and repositioning slides within cassettes and between a microscope and storage, lacking a reliable mechanism for secure and oriented slide handling.
Innovation Solution
A mechanism comprising a feed arm with a rotatable draw-out spring wire and a slide magazine cassette with paired engagement structures, along with an elevator control system and a controller, enables automatic removal, examination, and repositioning of microscope slides within a cassette, ensuring secure and oriented handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing systems for organizing and automatically handling microscope slides are used, then slide storage and retrieval can be performed, but the systems are inefficient in transferring and repositioning slides within cassettes and between microscope and storage
Solution Approach 1:
The draw-out spring wire is pre-positioned within the feed arm channel, ready to engage slides before transfer operations begin. The engagement structures are pre-configured in the cassette to facilitate immediate slide engagement, eliminating setup time during slide handling operations.
Solution Approach 2:
The draw-out spring wire acts as an intermediary mechanism between the feed arm and the slides, enabling efficient transfer by mechanically engaging the slide edges and pulling them through the system. This intermediary component resolves the inefficiency in direct slide manipulation.
2Reliability
If existing slide handling mechanisms are used, then slides can be moved, but there is a lack of reliable mechanism for secure and oriented slide handling
Solution Approach 1:
The engagement structures are specifically designed with localized features that engage only the edges of the slides, providing secure holding at critical points while leaving the rest of the slide undisturbed. This localized engagement ensures reliable orientation and positioning without requiring complex overall mechanisms.
Solution Approach 2:
The draw-out spring wire automatically engages and disengages slides through its spring-loaded design, self-regulating the force applied to maintain secure contact during transfer operations. The mechanism self-adjusts to maintain reliable slide handling without external intervention.
3Extent of automation
If manual slide handling is performed, then flexibility in positioning is maintained, but automation and throughput are reduced
Solution Approach 1:
Manual mechanical manipulation of slides is replaced by the automated draw-out spring wire mechanism that mechanically engages and transports slides through the system. This substitution maintains precise positioning capability while achieving full automation of the handling process.
