Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal incubation devices often create unwanted temperature gradients, leading to condensation at the top of sample containers, which reduces sample volume and can alter assay results, and existing solutions like heated covers or mineral oil are not effective or compatible with automated processes.
Innovation Solution
A heating element with an opening above the sample well, positioned to heat the top surface of the container, maintaining the top surface at a temperature higher than the sample well, thereby preventing condensation, and allowing for automated access and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heated cover is used to prevent condensation, then condensation is minimized, but access to the sample becomes difficult
Solution Approach 1:
The heating element is segmented into a frame structure with four sides and an open top, allowing the heating function to be separated from the sample access path. This enables samples to be accessed through the open top while the sides remain heated to prevent condensation.
Solution Approach 2:
The cover is completely removed from the heating element design, extracting the obstruction that prevented sample access. The heating function is maintained through the side walls and base, while the top remains open for easy sample manipulation.
2Object-affected harmful factors
If mineral oil is used to create a vapor barrier, then condensation is prevented, but sample access becomes cumbersome and assay compatibility is limited
Solution Approach 1:
A frame-shaped heating element acts as an intermediary structure that provides thermal control without requiring chemical additives. The heating element mediates between the heat source and the sample, preventing condensation through thermal management rather than chemical barriers.
3Device complexity
If the top of the container is not heated, then the heating element structure is simple, but temperature gradients cause condensation
Solution Approach 1:
The heating element applies heat locally to the sides and base of the container through its frame structure, creating a temperature gradient that prevents condensation on the container walls while leaving the top open for access. This localized heating approach targets the specific areas where condensation forms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively minimizes condensation, maintains sample volume, and enables efficient automated processing by maintaining the top surface of the container at a higher temperature than the sample well, preventing condensation and allowing for direct access and manipulation of samples.
Implementation Method 1
