Temperature Sensor Mounting Structure Flow Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation structure of existing temperature sensors hampers the responsiveness due to a significant difference in the flow direction of the measurement-subject medium, making it difficult for the medium to enter the introducing hole, thereby deteriorating the sensor's performance.
Innovation Solution
A temperature sensor design featuring a second case with a threaded portion and a projection that changes the flow direction of the measurement-subject medium, ensuring it aligns with the sensor unit, improving the medium's introduction and responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the temperature sensor is installed with the introducing hole perpendicular to the passage flow direction, then the sensor structure is simple and easy to manufacture, but the measurement-subject medium cannot easily enter the introducing hole, deteriorating sensor responsiveness
Solution Approach 1:
The patent introduces a flow direction changing portion that redirects the measurement-subject medium from the passage flow direction to the introducing hole direction. This dimensional redirection allows the medium to enter the introducing hole more easily without changing the overall perpendicular installation configuration, thereby improving responsiveness while maintaining manufacturing simplicity
Solution Approach 2:
The flow direction changing portion acts as an intermediary element between the passage and the introducing hole. It mediates the flow direction transition, enabling the measurement-subject medium to smoothly change direction and enter the introducing hole, thus resolving the contradiction between simple installation structure and improved responsiveness

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 modified structure enhances the responsiveness of the temperature sensor by facilitating easier entry of the measurement-subject medium into the sensor unit, improving its performance and accuracy.
Implementation Method 1
forming a resistance thermometer element(s), a resistance value of which changes depending on the temperature, at the sensor unit to output a sensor signal, which corresponds to the temperature

AI summary
A second case includes a projection that projects on an opposite side of a threaded portion of the second case, which is opposite from a first case, while the projection is placed in a passage when the second case is installed to an installation-subject member. An opening is formed in a visible area of an outer peripheral surface of the projection, which is visible at a time of viewing the outer peripheral surface in a flow direction of the measurement-subject medium upon installation of the second case to the installation-subject member, and the projection includes a flow direction changing portion that changes a flow direction of the measurement-subject medium, which is introduced from the passage into an introducing hole through the opening, from a direction along the passage to a direction toward the sensor unit.
