Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature determination devices face challenges due to poor heat transfer between the object and the temperature sensor, resulting in inaccurate temperature readings.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the determination element is arranged within the wall without direct contact to the object, then electrical insulation is improved, but heat transfer deteriorates
Solution Approach 1:
A thermally conductive contact element is introduced as an intermediary component between the object and the determination element. This contact element serves as a thermal bridge that conducts heat from the object to the determination element while maintaining electrical insulation through the non-conductive wall material, thus resolving the contradiction between electrical insulation and heat transfer.
Solution Approach 2:
The thermal connection path is segmented into distinct functional zones: the object surface, the thermally conductive contact element, the wall material providing electrical insulation, and the determination element. This segmentation allows each component to optimize its specific function - thermal conduction where needed and electrical insulation where required.
2Measurement precision
If a thermally conductive contact element is introduced to improve heat transfer, then temperature determination accuracy is improved, but device complexity increases
Solution Approach 1:
The contact element is merged with the wall structure, where the thermally conductive material is integrated directly into the wall body. This combining approach eliminates the need for separate mounting fixtures or additional components, reducing overall device complexity while maintaining the thermal bridge function.
Solution Approach 2:
The contact element serves multiple functions simultaneously: it acts as a thermal bridge for heat transfer, provides mechanical support for the determination element, and creates a stable mounting interface. This multi-functionality reduces the need for additional specialized components.
