Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature sensor mounting methods fail to accommodate misalignment between the sensor and the surface, leading to sub-optimal contact and inaccurate temperature readings.
Innovation Solution
A temperature sensor assembly with a resilient support and a spring mechanism that allows the sensor to move along a longitudinal axis, accommodating misalignment and ensuring optimal contact with the surface, while a resilient member urges the sensor into position, providing increasing force with deformation to maintain contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed sensor mounting is used, then the sensor position is stable, but the sensor cannot accommodate misalignment with the surface, resulting in sub-optimal contact
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed sensor mounting into a movable one. The sensor is mounted on a resilient support that allows it to move along a longitudinal axis, enabling the sensor to dynamically adjust its position to accommodate misalignment with irregular surfaces while maintaining stable contact during measurement
Solution Approach 2:
The patent applies parameter changes by modifying the physical state of the sensor mounting system. A resilient member (spring) is introduced to provide a variable positioning parameter, allowing the sensor to change its position along the longitudinal axis in response to surface irregularities, thereby optimizing contact conditions
2Measurement precision
If the sensor is made movable to accommodate misalignment, then surface contact is improved, but the sensor mounting complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the sensor mounting system into distinct functional components: a resilient support for positioning, a resilient member (spring) for urging, and a sensor holder for securing. This modular segmentation simplifies the overall design while achieving the desired movement capability for improved measurement accuracy
3Force
If a resilient member is added to urge the sensor into position, then contact force is improved, but the device complexity increases
Solution Approach 1:
The patent applies self-service by utilizing the natural elastic properties of the resilient member (spring) to automatically generate the required contact force. The spring's inherent ability to store and release mechanical energy eliminates the need for external actuation mechanisms, maintaining simplicity while ensuring consistent sensor-to-surface contact force
