Incubation Tray Multi-Zone Heating for Uniform Reaction Cup Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing incubation trays for chemiluminescent immunoassays suffer from uneven temperature distribution due to bottom heating, leading to potential incubation failures and inaccurate detection results.
Innovation Solution
The incubation tray employs a dual temperature control mechanism with lower, middle, and upper temperature control components, along with a thermal insulation layer, to maintain uniform and stable temperatures within the incubation chamber, using sensors and overheat protectors to regulate heating circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If bottom heating is used in the incubation tray, then heating function is provided, but uneven temperature distribution occurs within the incubation chamber
Solution Approach 1:
The heating system is segmented into multiple independent heating modules (first heating module at the bottom, second heating module in the middle, third heating module at the top) that can be controlled separately. This segmentation allows different regions of the incubation chamber to be heated independently, resolving the uneven temperature distribution problem caused by single bottom heating while improving incubation reliability through multi-point temperature control.
Solution Approach 2:
Different heating modules are positioned at different locations (bottom, middle, top) of the incubation chamber to provide localized heating. Each heating module addresses the thermal needs of its specific region, creating uniform temperature distribution throughout the entire chamber while ensuring reliable incubation conditions for reaction cups placed at various positions.
2Temperature
If multiple temperature control components are added, then temperature uniformity and stability are improved, but device complexity increases
Solution Approach 1:
The temperature control system is divided into three independent control modules, each with its own heating element and temperature sensor. This segmentation enables decentralized control where each module manages its local temperature zone independently, achieving precise overall temperature control without requiring a single complex centralized control system.
Solution Approach 2:
The temperature control approach transitions from one-dimensional (single bottom heating) to three-dimensional (bottom, middle, and top heating modules distributed throughout the chamber). This spatial distribution of heating and sensing elements across multiple dimensions enables comprehensive temperature control while maintaining manageable system complexity through modular design.
