Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor pressing members often result in uneven force distribution when pressing sensors against measurement targets, leading to potential inaccuracies in sensor measurements.
Innovation Solution
A sensor pressing member with an elastic body that includes a cavity, allowing for uniform pressure distribution by sandwiching the sensor against the measurement target, and a recessed side surface to prevent protrusion and ensure consistent force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional sensor pressing member uses a thin plate-shaped elastic member to press the sensor, then the sensor can be pressed against the measurement target with predetermined pressure, but the force pressing down on the sensor becomes uneven depending on the area, leading to measurement inaccuracies
Solution Approach 1:
The elastic body is provided with a cavity (porous structure) that allows it to deform more uniformly when pressing the sensor against the measurement target. This cavity structure enables the elastic body to distribute the pressing force evenly across the sensor surface, preventing localized stress concentration and ensuring uniform contact pressure, thereby improving measurement accuracy
Solution Approach 2:
The invention changes the structural parameters of the elastic member by introducing a cavity, transforming it from a solid thin plate to a hollow elastic body. This parameter change allows the elastic body to achieve better force distribution characteristics while maintaining the required pressing force, resolving the contradiction between force uniformity and measurement precision

AI summary
A sensor pressing member to which a sensor is attached such that the sensor is exposed toward a measurement target. The sensor pressing member presses the sensor in a first direction relative to the measurement target to bring the sensor into contact with the measurement target. The sensor pressing member includes an elastic body positioned opposite the measurement target with the sensor in between in the first direction. The elastic body includes a cavity therein.
