Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector temperature detection assemblies face reliability issues due to the elastic thermal conductive pad loosening when subjected to pulling forces, leading to inconsistent thermal contact and inaccurate temperature detection.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastic thermal conductive pad is inserted into the slot of the housing with an interference fit, then the thermal contact between the pad and connection terminal is initially good, but the pad is easy to loosen and be pulled out when subjected to pulling force
Solution Approach 1:
The fixing structure is divided into multiple components: the retainer with clamping arms, the housing with positioning slots, and the elastic thermal conductive pad. This segmentation allows each component to perform its specific function - the retainer provides mechanical retention, the housing provides positioning, and the pad maintains thermal contact, collectively solving the pulling force resistance problem while preserving thermal reliability
Solution Approach 2:
The retainer is pre-installed on the housing before the elastic thermal conductive pad is inserted. The clamping arms are positioned in advance to clamp the pad after insertion, preventing the pad from being pulled out before the temperature sensor assembly is fully assembled and secured
2Reliability
If the elastic thermal conductive pad is made elastic to maintain thermal contact, then thermal conductivity is improved, but the pad cannot resist pulling forces effectively
Solution Approach 1:
The retainer acts as an intermediary between the housing and the elastic thermal conductive pad. It transfers and distributes the mechanical retention force to the pad through its clamping arms, allowing the pad to maintain its elastic properties for thermal contact while the retainer handles the pulling force resistance
Solution Approach 2:
The temperature detection assembly combines materials with different properties: the elastic thermal conductive pad uses elastic materials for thermal contact, while the retainer and housing use rigid materials for mechanical strength and force resistance, creating a composite structure that leverages the advantages of each material type
