Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Temperature-controlled baths struggle to maintain a sample's temperature at a fixed level after reaching a target temperature, due to temperature fluctuations caused by air with adjusted temperature coming into contact with the sample.
Innovation Solution
A temperature-controlled bath system with a thermally conductive wall separating the temperature-controlled chamber and the sample holding chamber, featuring a connection cut-off mechanism that allows for swift temperature changes and subsequent isolation to maintain the sample's temperature, utilizing blower means to circulate and control gas temperature, and including features like radiator plates and optically transparent windows for measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If temperature control means sends air with adjusted temperature to change sample temperature, then temperature change speed is improved, but temperature stability after change deteriorates
Solution Approach 1:
The system divides the chamber into a temperature-controlled chamber and a sample holding chamber separated by a thermally conducive wall. This segmentation allows independent temperature control of each chamber, enabling rapid temperature changes in the sample chamber without causing fluctuations in the sample temperature.
Solution Approach 2:
The thermally conducive wall acts as an intermediary between the temperature-controlled chamber and the sample holding chamber. It transfers temperature changes from the controlled chamber to the sample chamber gradually and smoothly, preventing direct thermal shock and temperature fluctuations to the sample.
2Adaptability or versatility
If connection between chambers is maintained for continuous temperature control, then temperature adjustment flexibility is improved, but temperature stability deteriorates
Solution Approach 1:
The connection cut-off means enables dynamic control of the connection state between chambers. The system can switch between connected and cut-off states based on operational requirements, allowing flexible temperature adjustment when connected and stable maintenance when cut-off.

AI summary
A temperature-controlled bath capable of swiftly changing the temperature of a sample to a target temperature and maintaining the temperature of the sample at a fixed temperature after the temperature change is provided. A temperature-controlled bath includes a temperature changing means, a temperature-controlled chamber, a sample holding chamber, and connection cut-off means. The temperature changing means is disposed in the temperature-controlled chamber, and the temperature of the temperature-controlled chamber is adjusted by the temperature changing means. The sample holding chamber is separated from the temperature-controlled chamber by a thermally conducive wall, and contains a sample therein. The connection cut-off means change a connection between the temperature-controlled chamber and the sample holding chamber to a connected state or a cut-off state.
