Ring Connector Latch Mechanism for Accurate Fluid Flow Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic fluid flow systems face challenges in maintaining high accuracy of fluid flow monitoring, particularly in low-flow situations, due to the need for precise weight measurements. Secure and reliable interface mechanisms are required to ensure accurate transfer of downward forces and repeated engagements/disengagements with different fluid collection systems.
Innovation Solution
The automatic fluid flow measuring system incorporates a ring connector with a load cell, featuring an engagement structure such as a latch or spring clip mechanism, which securely couples the ring connector to the load cell. This configuration ensures accurate transfer of forces and provides a reliable, repeatable connection for fluid flow monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a secure engagement structure is implemented to ensure accurate force transfer, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces a load cell as an intermediary device between the ring connector and the weighing mechanism. The load cell accurately measures weight changes while the ring connector provides secure mechanical engagement. This intermediary approach separates the measurement function from the connection function, improving measurement precision without requiring the engagement structure itself to be overly complex.
Solution Approach 2:
The interface mechanism is segmented into distinct functional components: the ring connector for secure mechanical engagement, the load cell for precise weight measurement, and the engagement structure for reliable connection. This segmentation allows each component to be optimized independently - the ring connector provides secure force transfer while the load cell handles measurement, resolving the contradiction between measurement precision and device complexity.
2Reliability
If a latch mechanism is used to secure repeated engagements, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The engagement structure is designed to be self-securing through the latch mechanism that automatically engages when the ring connector is properly positioned on the load cell. The system serves itself by having the components guide their own engagement through aligned features and automatic latching, improving reliability without requiring complex manual operation procedures.
Solution Approach 2:
The latch mechanism is pre-configured in an engaged position that automatically secures the connection once the ring connector is placed on the load cell. The alignment features and guide structures are designed beforehand to ensure proper positioning, so the reliable connection is established through the preliminary design of the engagement geometry rather than complex operational steps.
3Measurement precision
If electrical contacts are positioned perpendicular to surfaces, then measurement precision is improved, but manufacturing precision requirements increase
Solution Approach 1:
The electrical contacts are designed with perpendicular orientation to the surfaces, creating equipotential contact areas that ensure consistent electrical connection regardless of minor manufacturing variations. This perpendicular arrangement establishes a reference geometry that maintains measurement precision by ensuring uniform contact pressure and electrical connection across the interface.
Solution Approach 2:
The electrical contact surfaces are designed with asymmetric perpendicular orientation rather than parallel alignment. This asymmetric perpendicular configuration provides a more robust reference for maintaining contact integrity and measurement accuracy, as the perpendicular geometry is less sensitive to lateral misalignments during assembly, thereby reducing the actual manufacturing precision requirements despite the stricter geometric specification.

AI summary
Embodiments disclosed herein are directed to apparatus and methods for automatic fluid flow system connectors. The system generally includes a load cell interface coupled to a console and a ring connector coupled to a fluid collection system. The ring connector can be releasably engaged with the load cell using an engagement structure such as a latch, locking arm, or spring clip mechanism. The ring connector and load cell can include electrical contacts configured to engage along an axis that extends perpendicular to a surface that the electrical contacts are disposed on. Advantageously, reduced wear on the electrical contacts should extend the usable life of the system.
