Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dynamic mechanical analyzers are unable to measure dynamic viscoelasticity of viscous fluid samples such as polymer melt viscosity, thermosetting resins, adhesives, and paints due to the inability to retain and stabilize these samples during temperature changes.
Innovation Solution
A sample container with a lower-end-closed tubular shape and an insertion jig having a smaller cross-sectional area than the sample cup opening, capable of transferring vibration to the sample, made from materials with high thermal conductivity like aluminum, gold, silver, or platinum, which allows for stable dynamic viscoelasticity measurement. The sample container design includes features such as a removable side portion for easy cleaning and a sharpened leading end for easier insertion into high viscosity samples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional sample container is used, then solid samples can be measured for dynamic viscoelasticity, but viscous fluid samples cannot be retained or stabilized during temperature changes
Solution Approach 1:
The patent introduces an insertion jig as an intermediary component that extends into the viscous fluid sample through the sample cup opening. This jig serves as a mediator to transfer vibration from the measurement device to the sample, enabling dynamic viscoelasticity measurement of viscous fluids that cannot be directly retained or stabilized in conventional containers.
2Use of energy by moving object
If the sample container is made of materials with high thermal conductivity, then thermal efficiency is improved, but manufacturing cost increases
Solution Approach 1:
The patent specifies that the sample container should be made of materials with high thermal conductivity such as aluminum, gold, silver, copper, or platinum. This parameter change in material selection optimizes thermal efficiency for temperature-controlled measurements, allowing efficient heat transfer during dynamic viscoelasticity measurements of viscous fluid samples.

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 measurement of dynamic viscoelasticity for viscous fluid samples by efficiently transferring vibrations and maintaining thermal conductivity, allowing for the reuse or disposable nature of the sample container based on the sample type.
Implementation Method 1
an insertion jig having a cross section smaller in area than the opening of the sample cup, being insertable into the sample cup through the opening, and being capable of transferring vibration to a sample contained in the sample cup
Implementation Method 2
the sample container is made of aluminum, gold, silver, copper, or platinum... since the sample container is made of a material with high thermal conductivity, it is possible to efficiently heat or cool the sample
