Integrated Resin Protector Temperature Sensor Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature sensors require increased manhours for fixing due to the need for a metal case and lug terminal, which complicates the process of bringing the heat transfer surface into tight contact with the temperature measurement object.
Innovation Solution
A temperature sensor design that incorporates a thermosensitive body, electric wires, a resin protector, and a fixing element such as a fixing hole or protrusion integrated with the protector, allowing for direct and simplified fixation to a temperature measurement object without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a metal case with lug terminal is used to house the thermosensitive body, then the heat transfer surface can be brought into tight contact with the temperature measurement object, but the working manhours for fixing increase due to additional assembly steps
Solution Approach 1:
The patent merges the fixing element with the protector component, creating an integrated structure where the protector serves dual purposes: protecting the thermosensitive body and providing the fixing function. This eliminates the need for separate metal case and lug terminal components, reducing assembly steps while maintaining tight contact capability through the integrated fixing element.
Solution Approach 2:
The patent extracts the fixing function from the traditional metal case structure and relocates it to the protector component. By taking out the fixing element as a separate functional feature within the protector, the design eliminates the need for complex metal case assembly while preserving the essential fixing capability needed for accurate temperature measurement.
2Reliability
If a metal case including lug terminal is used, then the thermosensitive body can be housed and fixed to the temperature measurement object, but the device complexity increases due to multiple components
Solution Approach 1:
The patent combines multiple functions into the protector component: protection of the thermosensitive body, housing for the thermosensitive body, and providing the fixing element. This merging reduces the total component count while maintaining fixing reliability through the integrated design that ensures proper contact and secure attachment.
Solution Approach 2:
The protector is designed as a multi-functional component that simultaneously serves as a protective enclosure, a housing structure, and a fixing mechanism. This universal design approach eliminates the need for separate metal case and lug terminal components, reducing device complexity while maintaining all necessary functions for reliable temperature measurement.
