Ball-and-socket coupling for manual spray head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual spray heads connected to flexible hose lines via screw-type couplings lack mobility and twisting capability, leading to unintentional loosening and wear due to transverse stress during use.
Innovation Solution
A ball-and-socket joint coupling is introduced between the manual spray head and the hose line, allowing for increased mobility and twisting without unscrewing, while maintaining a secure seal and separate functions for holding and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-type coupling is used to connect the manual spray head and the hose line, then the connection is secure and reliable, but the mobility and twisting capability of the manual spray head are restricted
Solution Approach 1:
The coupling is divided into two functional segments: a screw-type connection component for reliable attachment and a ball-and-socket joint component for mobility. This segmentation allows each part to perform its specialized function without compromising the other.
Solution Approach 2:
The ball-and-socket joint acts as an intermediary element between the screw-type connection and the manual spray head, allowing rotational movement while maintaining the secure connection provided by the screw threads.
2Ease of operation
If the manual spray head is made more mobile and twistable, then the usability is improved, but the screw connection may unintentionally loosen and wear occurs
Solution Approach 1:
The coupling transitions from a static rigid screw connection to a dynamic system with a ball-and-socket joint that allows controlled movement. This dynamic design accommodates the mobility needs while the screw threads maintain connection stability through their self-locking characteristic.
3Stability of the object's composition
If a rigid screw connection is used, then the connection stability is maintained, but the wear near the clamping point increases due to transverse stress
Solution Approach 1:
The ball-and-socket joint introduces spherical geometry to the coupling, allowing rotational movement that eliminates transverse stress on the screw connection. The spherical interface accommodates movement in multiple directions without creating bending loads on the threaded fasteners.

AI summary
A manual spray head can be connected with a flexible hose line by means of a coupling that has a ball-and-socket joint inserted between the manual spray head and the hose line. This arrangement not only increases the mobility and flexibility between the manual spray head and the flexible hose line, but also permits twisting of the manual spray head relative to the hose line without fear of unscrewing the screw-type connection or similar coupling provided between the manual spray head and the hose line.
