Articulation Fitting With Swivel Limiter For Sanitary Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary objects, such as hand showers, require an articulated mount that is easily adjustable yet stable in position, space-saving, and prevents undesirable orientations like pointing against the ceiling, with existing solutions failing to balance these requirements effectively.
Innovation Solution
An articulated mount featuring a rotationally symmetrical joint head with a disk-shaped surface, a bearing shell with a disk or spherical design, and a screw-nut mechanism for adjustable pivoting, along with an internal swivel angle limiter to restrict movement to specific planes, ensuring stability and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ball head with flattened area and spring-loaded piston is used, then the articulated arm can be fixed in a specific position, but the structure becomes more complex and larger
Solution Approach 1:
The invention extracts the spring-loaded piston and flattened area from the ball head, replacing them with a simpler nut that directly engages with the bearing shell's internal thread. This removes unnecessary complexity while maintaining the position stability function.
Solution Approach 2:
Instead of using a spring-loaded piston to press against a flattened ball head surface, the invention inverts the approach by having the nut engage directly with the bearing shell's internal thread structure. This reversal simplifies the mechanism while achieving the same fixing function.
2Ease of operation
If a plate screw is used to press the ball socket against the ball, then the joint can be adjusted, but the structure becomes more complex and the adjustment mechanism less smooth
Solution Approach 1:
The invention merges the ball socket and bearing shell into a single integrated component with an internal thread. The nut directly engages this integrated structure, eliminating the need for separate plate screws and reducing overall structural complexity while maintaining smooth adjustment.
Solution Approach 2:
The bearing shell with internal thread serves multiple functions: it acts as both the bearing structure and the mounting interface for the nut. This multi-functionality eliminates the need for separate plate screws, simplifying the overall structure while maintaining adjustment capability.
3Ease of operation
If the joint head has a large diameter rotationally symmetrical surface, then the articulated arm can pivot smoothly, but the space required for storage increases
Solution Approach 1:
The invention transitions from a traditional ball head design to a disk-shaped joint head with a rotationally symmetrical surface. This dimensional change allows for smooth pivoting motion while reducing the storage space requirement, as the disk can be compactly arranged within the bearing shell.
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 articulated mount allows smooth adjustment while maintaining stability and preventing undesirable orientations, ensuring the sanitary object remains secure and visually appealing, meeting the requirements of space-saving and user-friendly operation.
Implementation Method 1
The storage includes a screw that is stretched through an opening in the joint head and screwed to a nut of the storage
Implementation Method 2
The joint head, which has a rotationally symmetrical lateral surface, is mounted in the bearing. The axis of rotation of the rotationally symmetrical lateral surface of the articulated head then forms the axis about which the articulated arm can be pivoted
