Thermochromic Torque Seal for Electrical Connection Overheating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional torque seals for electrical connections do not provide adequate indication of overheating, which can lead to failure and potential fires due to improper torque specification or design, and they lack monitoring for continuous temperature assessment.
Innovation Solution
A color-changing torque seal that uses thermochromic material to visually indicate temperature changes, allowing for both loose connection detection and overheating monitoring, with automated image processing to determine corrective actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional torque seals are used to indicate loose connections, then visual indication of loose connections is provided, but indication of overheating is not provided
Solution Approach 1:
The torque seal is designed to perform multiple functions: it maintains the visual indication of loose connections while adding temperature monitoring capability through thermochromic material. This allows a single component to provide both mechanical connection status and thermal condition indication, resolving the contradiction between reliability and versatility.
Solution Approach 2:
The patent incorporates thermochromic material that changes color in response to temperature changes, enabling the torque seal to indicate overheating conditions. This color change mechanism adds thermal monitoring capability to the existing mechanical indication function, expanding the seal's versatility without compromising its reliability.
2Reliability
If continuous temperature monitoring is implemented, then overheating detection is improved, but device complexity increases
Solution Approach 1:
The torque seal incorporates thermochromic material that automatically changes color in response to temperature changes without requiring external power, sensors, or electronic components. This self-service approach provides continuous temperature monitoring while maintaining simplicity, as the monitoring function is intrinsic to the seal material itself rather than requiring separate monitoring systems.
Solution Approach 2:
The patent replaces complex electronic temperature sensing and signaling systems with a passive thermochromic material that provides temperature indication through inherent color changes. This substitution eliminates the need for power sources, electronic circuits, and additional components, reducing device complexity while maintaining reliable overheating detection.
