Rotatable Hose Adapter With Snap Ring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose fittings are either overly complex and expensive for rotatable applications or require multiple types for both rotatable and non-rotatable uses, leading to high storage costs due to the need for multiple inventory items.
Innovation Solution
A rotatable adapter that can be retrofitted to non-rotatable hose fittings, allowing 360° rotation in both directions, featuring a snap ring mechanism for secure connection, media resistance, and compatibility with various hose and cable fittings, including sealing rings for enhanced durability and sealing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotatable hose fitting is designed with a screw attachment and guide attachment rotatably mounted relative to one another, then rotation is enabled, but the design becomes too complicated and expensive
Solution Approach 1:
The invention divides the hose fitting into two separate functional components: a rotatable adapter that handles rotation and a simple screw connection that handles mounting. The adapter includes a first socket for the screw connection and a second socket that rotates relative to it, with a seal between them. This segmentation allows each component to be optimized independently - the screw connection remains simple while the rotation function is added through the adapter mechanism.
Solution Approach 2:
The rotatable adapter acts as an intermediary component between the wall mounting and the hose fitting. It mediates the rotation requirement by providing a rotating connection point while leaving the wall mounting itself simple and non-rotatable. The adapter includes a seal between its sockets to prevent media leakage during rotation, solving the rotation problem without complicating the overall hose fitting design.
2Adaptability or versatility
If both rotatable and non-rotatable hose fittings are kept in stock for different applications, then all application requirements are met, but storage costs increase due to high inventory variety
Solution Approach 1:
The rotatable adapter is designed as a universal component that can be combined with any standard hose fitting or cable fitting. It provides rotation capability for all applications where it is needed, while standard non-rotatable fittings remain unchanged for applications where rotation is not required. This multi-functionality approach allows a single adapter design to serve multiple purposes across different installation scenarios.
Solution Approach 2:
The invention introduces dynamic adaptability by allowing the rotation function to be added or removed based on application requirements. The rotatable adapter can be installed on standard fittings to enable rotation when needed, or left off when rotation is not required. This dynamic configuration approach eliminates the need to maintain separate rotatable and non-rotatable fitting inventories.
3Reliability
If a hose fitting is designed to be rotatable to prevent hose twisting, then hose protection is improved, but the screw attachment can be loosened by tensile forces causing the fitting to tear apart
Solution Approach 1:
The invention separates the tensile load path from the rotation mechanism. The screw connection between the adapter and wall mounting is designed to handle only mounting forces, while the rotation occurs at the second socket where the hose fitting connects. This segmentation prevents tensile forces from acting on the screw attachment during rotation, eliminating the risk of the fitting tearing apart while maintaining hose protection through the rotation capability.
