Thermal Cycler Adaptor With Upstanding Draft Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermal cycler systems often face inefficiencies when designed to be compatible with multiple types of sample holders, particularly due to exposure of the sample block to air drafts when using semi-skirted holders, affecting thermal performance and complicating the removal process.
Innovation Solution
A thermal cycler system incorporating an adaptor with an upstanding peripheral side wall that extends upward to protect the sample block from air drafts and includes features for secure placement and easy ejection of sample holders, compatible with both full-skirted and semi-skirted designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the thermal cycler system is designed to be compatible with multiple types of sample holders (full-skirted and semi-skirted), then the adaptability of the system is improved, but the thermal consistency and performance deteriorate due to air draft exposure
Solution Approach 1:
The patent introduces a shield or baffle structure as an intermediary element between the sample block and the air draft sources. This shield selectively blocks air drafts from reaching the sample block when semi-skirted sample holders are used, while maintaining compatibility with both full-skirted and semi-skirted holder types. The shield acts as a mediator that allows the system to accommodate different holder types without compromising thermal consistency.
2Object-affected harmful factors
If the peripheral side wall of the adaptor extends upward toward the sample holder, then the protection from air drafts is improved, but the device complexity increases
Solution Approach 1:
The patent divides the protective structure into separate functional components: the adaptor with its upstanding peripheral side wall and the sample block with its own peripheral side wall. This segmentation allows each component to perform its specific function independently - the adaptor provides structural support and partial protection, while the sample block provides the thermal processing environment. The segmented design reduces overall complexity compared to a fully integrated protective structure.
3Ease of operation
If the adaptor includes features for secure placement and easy ejection of sample holders, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent incorporates self-ejection features in the adaptor design that automatically eject the sample holder from the sample block after the thermal cycling process completes. The adaptor's upstanding peripheral side wall and associated mechanical features create a self-service system where the sample holder is automatically released and ejected without requiring manual intervention, thereby improving ease of operation while adding minimal complexity through automated mechanical features.

AI summary
A thermal cycler system comprises a sample block configured to receive a sample holder configured to receive a plurality of samples; an adaptor configured to surround a periphery of the sample block; and a drip pan configured to surround a periphery of the adaptor. The drip pan comprises one or more ejector mechanisms and one or more openings, the one or more ejector mechanisms configured to respectively extend through the one or more openings into contact with the sample holder in a state of the sample holder received by the sample block and the adaptor surrounding the periphery of the sample block.
