Sanitary Mount Fastener With Tool-Free Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for sanitary items on building walls lack simplicity in handling and user understanding, with limitations in tool-free fine adjustment and attachment to mounting frames.
Innovation Solution
A fastening device featuring a bolt that can be axially displaced from a non-contact to a contact position, acting as both a coarse adjustment axial slide and a rotary handle for fine adjustment, with a channel-shaped connecting part and radial shoulders for easy operation, and optionally enhanced with surface features for quick recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fastening device with separate coarse and fine adjustment mechanisms is used, then the adjustment functionality is complete, but the device complexity and handling difficulty increase
Solution Approach 1:
The patent combines the coarse adjustment (axial sliding) and fine adjustment (rotational) functions into a single latch element. This latch can move axially along the screw element and also rotate, integrating two adjustment mechanisms into one component, thereby reducing overall device complexity while maintaining complete adjustment functionality
Solution Approach 2:
The latch is designed as a multi-functional element that performs both coarse adjustment through axial displacement and fine adjustment through rotation. This universal component eliminates the need for separate adjustment mechanisms, simplifying the device structure and improving ease of operation
2Productivity
If a quick adjustment mechanism is implemented, then adjustment speed increases, but the ability to perform fine manual adjustment is lost
Solution Approach 1:
The latch is designed with dynamic capabilities, allowing it to switch between two modes of operation: axial sliding for quick coarse adjustment and rotation for precise fine adjustment. This dynamic behavior enables the user to perform both rapid positioning and precise tuning with a single component
Solution Approach 2:
The invention changes the operational parameters of the latch by allowing it to transition between axial movement (for quick adjustment) and rotational movement (for fine adjustment). This parameter change enables the system to achieve both fast positioning and precise control
3Reliability
If the screw element remains continuously engaged with the internal thread, then secure fastening is maintained, but repositioning and adjustment become difficult
Solution Approach 1:
The system dynamically switches between two states: engaged state where the screw element is threaded into the internal thread for secure fastening, and disengaged state where the screw element is radially displaced for easy repositioning. The latch controls this dynamic transition, allowing users to achieve both secure mounting and easy adjustment as needed

AI summary
The invention relates to a device (1) for fastening a sanitary item, in particular a washbasin or a mounting frame for holding a sanitary item, to a building wall or to a support, with a bolt-shaped or rod-shaped screw element (4) which has an external thread at least along one longitudinal section (4.1) has, and a nut-like counter-element. So that such a device can be produced inexpensively and offers quick adjustment that is easy to operate without tools, the invention provides that the counter-element is composed of a channel-shaped connecting part (5) with an inner part thread (5.7) and a latch (6), with the Connecting part (5) has a free space into which the screw element (4) can be displaced radially in order to loosen the screw element (4) from the inner part thread (5.7), the bolt (6) on the connecting part being essentially axial to the longitudinal axis of the screw element ( 4) is displaceable from a non-contact position to a contact position and vice versa, and wherein the bolt (6) in the contact position holds the screw element (4) in engagement with the inner part thread (5.7).
