Solution Overview
Problem
Existing temperature measurement devices face challenges in accurately and quickly measuring temperatures of objects, especially batteries, while minimizing electricity flow and contact pressure, particularly when there is a large distance between the object and the temperature-sensitive section.
Innovation Solution
A temperature measuring device comprising an electrical temperature measuring instrument with a heat transfer part made of elastomer, embedding the temperature-sensitive section, and a heat insulation part covering one side of the heat transfer part, which has higher thermal conductivity than the insulation part, allowing efficient heat transfer while reducing electrical contact and contact pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature sensitive section is placed close to the object for temperature measurement, then measurement accuracy and speed improve, but electrical contact and contact pressure increase
Solution Approach 1:
The patent introduces an elastomeric material as an intermediary between the temperature sensitive section and the object being measured. This elastomer serves multiple functions: it provides thermal conduction path for accurate temperature measurement, while simultaneously providing electrical insulation to prevent short circuits, and its elastic properties reduce contact pressure on the measured object.
2Measurement precision
If heat insulation is applied to the heat transfer part, then heat dissipation is reduced improving measurement accuracy, but thermal conduction to the temperature sensitive section is also reduced
Solution Approach 1:
The patent applies heat insulation selectively to specific regions of the elastomeric heat transfer part. The heat insulation layer is applied to the outer surface of the elastomer, creating a structure where the inner region maintains high thermal conductivity for rapid heat transfer to the temperature sensitive section, while the outer insulated region prevents heat loss to the environment, thus improving measurement accuracy without compromising response speed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate and rapid temperature measurement with reduced electricity flow and minimal contact pressure, as demonstrated by improved performance compared to comparative examples, with a temperature difference of about 2 degrees Celsius and measurement delay of 30 seconds in steady state.
Implementation Method 1
the heat transfer part having a thermal conductivity that is greater than a thermal conductivity of the heat insulation part
Implementation Method 2
the heat is difficult to dissipate by thermal conduction from the heat transfer part by means of the heat insulation part covering a single side of the heat transfer part
Implementation Method 3
since the temperature sensitive section is embedded in the heat transfer part, electrical contact can be avoided between the object for which the temperature is to be measured and the temperature sensitive section
