Rotatable Connector Wire Spooling for Respiratory Gas Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swivel ports for respiratory gas delivery systems require complex assembly and multiple parts, leading to issues with wire pinching and tangling during rotation, which complicates the integration of power supply for heating mechanisms.
Innovation Solution
A rotatable connection assembly with a housing, port assembly, and wire assembly that allows for the spooling of electrical wires around a central axis, enabling rotation without pinching or tangling, while providing power to connected components like heating tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional swivel ports are used to provide power for heating mechanisms, then power supply is achieved, but wire pinching and tangling occurs during rotation
Solution Approach 1:
The wire assembly is segmented into multiple wires that are individually routed through separate channels in the rotatable connection assembly. This segmentation prevents the wires from tangling with each other during rotation, as each wire travels through its own dedicated pathway, eliminating the wire pinching and tangling problems associated with conventional swivel ports.
2Reliability
If conventional swivel ports with multiple parts are used, then power supply capability is achieved, but assembly process becomes complex and lengthy
Solution Approach 1:
The invention merges the housing, port assembly, and wire assembly into a single integrated rotatable connection assembly. The housing forms a chamber that receives and guides the wire assembly, while the port assembly is integrated into the housing structure. This consolidation reduces the number of separate parts and simplifies the assembly process, eliminating the need for complex multi-step assembly procedures required by conventional swivel ports.
3Adaptability or versatility
If wires are routed through a rotatable connection assembly, then power can be supplied to rotating components, but wire pinching and tangling occurs
Solution Approach 1:
The invention introduces channels as intermediary structures within the housing that guide and constrain the wire assembly. These channels act as mediators between the stationary power source and the rotating component, providing a controlled pathway that allows the wires to flex and move during rotation without pinching or tangling. The channels ensure proper wire routing while maintaining rotational freedom.

AI summary
A connection assembly for rotateably and electrically coupling an accessory to a main device includes a housing portion, a rotatable port assembly, and a wire assembly. An end of the port assembly is coupled to the accessory. The port assembly includes an electrical connector member having a first connector end electrically coupled to the accessory. The wire assembly has an electrical wire member having a first end electrically coupled to a second connector end of the electrical connector member and a second end electrically coupled to a power supply. The wire member is spooled around the port assembly and encased in a chamber defined between the housing portion and the port assembly. Rotation of the port assembly in opposite directions causes the electrical wire member to spool more and less tightly around the port assembly without causing pinching or tangling of wires.
