Wall Fastening Assembly With Radial Locking for Sanitary Fixtures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for sanitary devices, such as toilets, lack flexibility and universality in design, making it difficult to securely mount devices with conventional round openings without altering their design or requiring complex assembly processes.
Innovation Solution
A fastening system featuring a mounting element with a hollow-cylindrical housing and a laterally or radially movable locking part that can be moved from an insertion position to a locking position, allowing secure attachment to a wall without rotating the housing, and accommodating devices with conventional round openings by using a locking bolt and pin mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening system uses a housing that must be rotated to lock, then the locking mechanism can be secure, but the mounting process becomes more complex and time-consuming
Solution Approach 1:
The locking part is designed to move dynamically from an insertion position to a locking position through radial or lateral movement, eliminating the need for rotational housing movement. This dynamic transformation simplifies the mounting process while maintaining secure locking through the axial stop mechanism formed by the protruding locking element.
2Manufacturing precision
If a fastening system is designed for specific opening shapes, then the locking can be precise, but the adaptability to different sanitary device designs is reduced
Solution Approach 1:
The mounting element is designed with a universal hollow-cylindrical housing and a movable locking part that can accommodate various opening shapes (round, oval, rectangular) in sanitary devices. The locking part's radial movement capability allows it to adapt to different geometries while maintaining precise locking through the axial stop mechanism, making the fastening system universally applicable.
3Ease of operation
If the locking element is set back in the housing, then the insertion is easier, but the locking strength is reduced
Solution Approach 1:
The locking element is initially set back in the housing to facilitate easy insertion of the mounting element into the sanitary device opening. During the locking process, the locking part moves radially or laterally, causing the locking element to protrude axially beyond the housing to form a strong axial stop against the device wall, thereby achieving both easy insertion and strong locking.
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
Enables secure, flexible, and easy mounting of sanitary devices on walls with minimal influence on the device's design, allowing for alignment of the locking pin for optimal attachment and accommodating devices with conventional round openings, ensuring reliable attachment and easy installation.
Implementation Method 1
The locking part can, for example, have elastically deformable or flexibly deformable elements, e.g. a radially flexibly movable locking element. The locking element can be designed, for example, as a spring element that can be pressed radially outwards.

AI summary
The wall mounting system for sanitary fixtures comprises a mounting element (2) for insertion into a mounting wall (9) of the sanitary fixture (1), the mounting element (2) having a receiving area (3) at a distal end. The mounting element (2) is a hollow cylindrical housing (20) comprising a locking element (4) inserted therein. The locking element (4) is arranged to be movable relative to the housing (20) such that the locking element (4) is movable from a first insertion position of the mounting element (2) to a second locking position of the mounting element (2), wherein an outer circumference of a locking element (400) of the locking element (4) does not project radially beyond an outer circumference of the housing (20) in the insertion position, and wherein an outer circumference of the locking element (400) of the locking element (4) projects radially beyond the outer circumference of the housing (20) in the locking position.
