Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion sets lack a convenient and secure mechanism for attaching and detaching the hub member, which complicates the connection and rotation of fluid conduits, affecting ease of use and reliability.
Innovation Solution
A hub member with radially compressible pads and movable connection features that allow for secure attachment and detachment, enabling rotation relative to the housing when needed, facilitating easy connection and disconnection with a simple squeezing action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure attachment mechanism is used to ensure reliable connection between hub member and housing, then connection reliability is improved, but the complexity of the connection and detachment operation increases
Solution Approach 1:
The connection features are designed to be movable rather than fixed, allowing them to transition between engaged and disengaged states. The radially inward movement of connection features enables secure attachment while their ability to move provides easy detachment, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The hub member utilizes radial compression as a parameter change mechanism. By applying radial inward force, the connection features move to engage with the housing, creating a secure connection. Releasing the force allows detachment, maintaining simplicity while ensuring reliability.
2Ease of operation
If the hub member is designed to be rotatable relative to the housing to facilitate fluid conduit connection, then ease of operation is improved, but the stability of the connection is reduced
Solution Approach 1:
The hub member allows rotational movement when needed for connecting fluid conduits, then locks into a stable engaged position. The connection features can move radially to provide both rotation capability and stable connection, resolving the contradiction between operational ease and connection stability.
3Ease of operation
If a simple squeezing action is used to attach and detach the hub member, then ease of operation is improved, but the secureness of attachment is reduced
Solution Approach 1:
The simple squeezing action changes the radial position parameter of the connection features, moving them inward to engage with the housing. This single parameter change achieves both easy operation and secure attachment, resolving the contradiction between simplicity and secureness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable and user-friendly mechanism for attaching and detaching the hub member, enhancing the ease of use and reliability of infusion sets by allowing for secure attachment and controlled rotation, thereby improving the overall functionality and usability.
Implementation Method 1
at least a portion of the hub member is configured to compress radially inward relative to the axis in response to the squeezing force being received by the pads

AI summary
A hub member for an infusion set device includes a body and pads configured to receive a squeezing force directed radially inward relative to an axis of the body. The body compresses radially inward relative to the axis in response to the squeezing force. A plurality of connection features on the body are moveable from a first position radially inward toward a second position when the hub member is compressed radially inward. The plurality of connection features engage one or more further connection features on a housing to attach the hub member to the housing when the plurality of connection features are in the first position, and disengage the one or more further connection features to release the hub member when the plurality of connection features are moved toward the second position.
