Spring-Locked Temperature Sensor for Vibration-Stable Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature sensors face challenges in maintaining reliable contact with the measured part, leading to potential degradation in temperature measurement performance, especially under varying loads and vibrations.
Innovation Solution
A temperature sensor design featuring a flexible thin-plate wire with a biasing member that includes a pressing part, a biasing spring, and a spring presser held by a holding member, where the spring presser has elastically deformable locking pieces that are regulated to prevent release from the holding member, ensuring consistent contact with the measured part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking piece is constrained in intersecting direction to prevent release, then the stability of locking is improved, but the device complexity increases
Solution Approach 1:
The regulating part is integrated into the existing structure of the biasing member, combining the locking regulation function with the overall biasing mechanism. This merging approach prevents release of the locking piece while avoiding the need for separate, additional complex components, thus maintaining structural efficiency.
2Measurement precision
If the sensor part is pressed firmly toward the part to be measured, then the temperature measurement precision is improved, but the sensor part may detach under vibrations and loads
Solution Approach 1:
The locking piece and locking part are configured to engage beforehand, creating a pre-established secure connection. This preliminary locking action ensures that the sensor part remains firmly pressed toward the part to be measured even before vibrations or loads occur, maintaining both measurement precision and contact stability.
Solution Approach 2:
The biasing part applies a continuous biasing force that counteracts external forces such as vibrations and loads. This counteracting force ensures the sensor part remains firmly pressed toward the part to be measured, maintaining measurement precision while preventing detachment under adverse conditions.

AI summary
A temperature sensor including a sensor part and a biasing member that is capable of pressing the sensor part. Here, the biasing member includes a pressing part, a biasing part, and a part to be held. The part to be held includes a locking piece that is elastically deformable in an intersecting direction intersecting with the pressing direction, and hooks that are locked by the holding member in a state where movement of the hooks to the other side in the pressing direction is regulated. The biasing member includes a regulating part that regulates movement of the locking piece in the intersecting direction and prevents release of locking between the hooks and the holding member.
