Fluid Line Quick Connector With Concealed QR Status Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick connectors for fluid lines lack efficient and automated methods for verifying proper connections, often requiring manual visual inspection and physical interaction, which can be cumbersome and less reliable.
Innovation Solution
Incorporation of a data matrix and a retainer assembly with a primary and secondary latch mechanism that allows for remote verification of connection status, enabling automated detection and verification of proper connections through a data matrix that is concealed or revealed based on the position of the secondary latch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual visual inspection is used to verify connections, then physical interaction and viewing by assembler/inspector is required, but the process becomes cumbersome and less reliable
Solution Approach 1:
The patent replaces manual visual inspection with an automated optical scanning system. A data matrix code on the quick connector is read by an automated scanner, eliminating the need for physical interaction and manual viewing by assemblers or inspectors. This substitution of mechanical/manual verification with automated optical detection resolves the contradiction by improving reliability through automation while simplifying operation.
2Extent of automation
If data matrix is always visible for verification, then automated detection is enabled, but the data matrix may be accessed or tampered with during operation
Solution Approach 1:
The patent implements a dynamic concealment mechanism where the data matrix is hidden during normal operation and only revealed during verification. The secondary latch mechanism dynamically changes the visibility state of the data matrix - concealed when the quick connector is assembled (preventing tampering) and revealed when verification is needed (enabling automated detection). This dynamic state change resolves the contradiction between automation enablement and tampering prevention.
Solution Approach 2:
The patent uses the preliminary action of assembling the quick connector to automatically conceal the data matrix before verification occurs. The assembly process itself performs the action of hiding the data matrix by closing the secondary latch, which secures the data matrix in a concealed position. This preliminary concealment action prevents tampering while preserving the ability to verify through automated scanning when needed.
3Object-affected harmful factors
If secondary latch conceals data matrix during operation, then tampering is prevented, but verification requires additional latch operation
Solution Approach 1:
The patent merges the verification trigger function with the existing secondary latch mechanism. The same secondary latch that conceals the data matrix during operation also serves as the trigger for revelation during verification. By pressing the secondary latch, the user simultaneously triggers the revelation mechanism and initiates the verification process. This merging of functions reduces device complexity by eliminating separate trigger mechanisms while maintaining protection during operation.
Data Source
AI summary
A fluid line quick connector serves to join fluid lines together in vehicle applications, as well as in industrial-manufacturing, aircraft, marine, and agricultural applications, among other possibilities. The fluid line quick connector has a retainer assembly with a primary latch and a secondary latch. A data matrix is provided, and can be in the form of a quick response (QR) code, as an example. In use, when the secondary latch is in the open position, the data matrix is partially or more concealed. And when the secondary latch is in the closed position, the partial or more concealment is absent and the data matrix can be properly read.
