Device for the wall installation of a sanitary furniture item
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for wall-installed sanitary furniture, such as toilets, face challenges in blind installation due to misalignment of tightening screws and the risk of screws becoming loose, leading to complicated and prolonged installation processes.
Innovation Solution
A device featuring a clamping sleeve with an external tubular housing and locking means that prevent radial movement, ensuring the orifice remains aligned with the affixing tube's slot, and an access rod with a cover element to prevent screw loss, facilitating precise and rapid installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tightening screw is accessed through a small hole in the lateral wall or from the base of the toilet, then the installation can be performed blind from the exterior, but the tightening screw may become misaligned with the slot in the affixing tube or become loose and fall during the threading operation
Solution Approach 1:
The patent introduces an intermediary structure (the clamping sleeve with external tubular housing and locking means) that mediates between the tightening screw and the affixing tube. The locking means engage with the internal wall of the through-hole to prevent radial movement of the clamping sleeve, ensuring the orifice remains aligned with the slot during blind installation. This intermediary structure eliminates the need to access the tightening screw through small holes while maintaining reliable alignment.
Solution Approach 2:
The patent applies preliminary action by pre-positioning the clamping sleeve with locking means that prevent radial movement before the tightening operation begins. The locking means are designed to engage with the through-hole wall in advance, ensuring that the orifice remains aligned with the slot throughout the tightening process. This preliminary positioning prevents misalignment and screw loss during the actual tightening operation.
2Productivity
If the clamping sleeve is inserted into the affixing tube to suspend the toilet, then the toilet can be affixed to the wall, but the sleeve may move causing misalignment between the tightening screw and the slot
Solution Approach 1:
The patent applies dynamics by designing the locking means to dynamically engage with the internal wall of the through-hole, preventing radial movement of the clamping sleeve. This dynamic engagement ensures that the orifice remains aligned with the slot during the insertion and tightening operations, maintaining precision while enabling rapid installation.
3Ease of operation
If the tightening screw is turned blind from the exterior, then the installation can be completed without removing the toilet, but it is extremely complicated to bring together the tightening key and the tightening screw
Solution Approach 1:
The external tubular housing of the clamping sleeve serves as an intermediary structure that provides direct access to the tightening screw from the exterior. The locking means prevent radial movement of this housing, ensuring the orifice remains aligned with the slot. This intermediary structure simplifies the blind tightening operation by eliminating the need to access the screw through small holes or from the base, while maintaining proper alignment throughout the operation.

AI summary
A device for the wall installation of a sanitary furniture item (15), comprising an affixing tube (17) to be anchored in a wall, a clamping sleeve (1) susceptible to surround in a state of use a section of said affixing tube (17), and a holding piece (2) coupleable with the clamping sleeve (1) via a through-hole (16) in the furniture item (15) in order to hold the sleeve (1) against an internal wall of said furniture item (15) during pre-installation, said clamping sleeve (1) including an orifice (3) provided with an internal thread (4) to receive a tightening screw (12) susceptible to act upon the slanting surface (19a) of a slot (19) in the affixing tube (17) and to cause a thrusting effect of the clamping sleeve (1) against the sanitary furniture item (15) suspended on the wall, characterised in that the clamping sleeve (1) body itself defines an external housing (7) including a section (8) adapted to facilitate the location of the tightening screw (12) or the orifice (3) from the exterior of the furniture item (15), and in that the holding piece (2) of the clamping sleeve (1) comprises locking means (9) for preventing the radial movement of the holding piece (2) relative to the furniture item (15). An access rod (11) for tightening a tightening screw (12) in a thread of an orifice (3) of the clamping sleeve (1) of said device is also provided, wherein said access rod (1 1) is associated with an element (14) which acts as a cover for said orifice (3), said cover (14) element including an orifice for the passage of the said access rod (11).
