Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a connection verifier that ensures a secure fluid connection in automotive systems, as incomplete connections can lead to leaks and other serious consequences, and existing solutions do not effectively verify the secure engagement of fluid connectors.
Innovation Solution
A connection verifier system comprising a cap, body, circuit board, and boot that uses sensors and a probe to detect the presence of snap rings, providing feedback through indicators, vibrations, or sound, and transmitting secure connection status wirelessly or via cable, ensuring proper fluid connection verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fluid connector uses a retaining clip or snap ring to secure the tube end form, then the connection can be made simple and quick, but the connection may fail if the tube end form is not fully inserted, causing fluid leaks
Solution Approach 1:
The patent implements a verification system that provides feedback to confirm proper connection. Sensors detect whether the tube end form is fully inserted into the fluid connector by monitoring the position of the retaining clip or snap ring. This feedback mechanism alerts the operator if the connection is incomplete, preventing fluid leaks while maintaining quick connection capability.
Solution Approach 2:
The patent replaces purely mechanical connection verification with sensor-based detection systems. Instead of relying solely on mechanical engagement of the snap ring, electronic sensors detect the connection status and provide verification signals, transitioning from mechanical-only to sensor-enhanced connection verification.
2Device complexity
If no connection verification system is used, then the device remains simple, but incomplete connections can lead to fluid leaks and serious consequences
Solution Approach 1:
The verification system provides automated feedback to confirm proper connection status. Sensors detect whether the tube end form is fully inserted and communicate this information to the operator through visual or electronic signals, ensuring reliable connection verification without significantly increasing system complexity.
Solution Approach 2:
The system performs self-verification of the connection status through integrated sensors that automatically detect whether the tube end form is properly seated. This self-service capability eliminates the need for manual verification steps while maintaining system simplicity.
3Productivity
If manual verification of fluid connections is performed, then the system remains simple, but it is time-consuming and prone to human error
Solution Approach 1:
The patent replaces manual visual inspection with automated sensor-based detection systems. Sensors electronically detect the connection status of tube end forms, providing rapid and accurate verification without human intervention, thereby increasing productivity while managing system complexity through standardized sensor integration.
Solution Approach 2:
The verification system performs automatic self-checks of connection status through integrated sensors that continuously monitor whether tube end forms are properly seated. This eliminates the need for manual verification steps, increasing productivity while keeping the system relatively simple through automated self-verification.
