Solution Overview

Problem

Existing fixing support solutions for sanitary facilities, such as toilets and washbasins, face issues with complexity, limited strength, and stability due to the use of rotating nuts, large dimensions, and material diversity, as well as complexity in production and installation.

Innovation Solution

A fixing support system featuring a split nut with resiliently connected longitudinal half-nuts and an anchor screw with a bent foot, allowing for easy installation and reliable anchoring to masonry, with inclined surfaces controlling clamping and enabling both longitudinal movement and rotation of the anchor screw.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rotating nut with partial thread is used, then the fixing support can be installed, but the device complexity increases and dimensions become larger

Engineering Contradiction:
Improveinstallation capabilityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The nut is divided into two separate half-nuts that are resiliently connected to the connecting pin. Each half-nut contains part of the nut thread, and together they form the complete threading interface. This segmentation simplifies the overall structure by eliminating the complex rotating mechanism while maintaining installation functionality through the split design that allows easier assembly and disassembly.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a box-like elongated body with rotating nut is used, then the fixing function is achieved, but the volume increases

Engineering Contradiction:
Improvefixing functionVSAvoidcomponent volume
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The bulky box-like structure is replaced by a compact connecting pin with resiliently attached half-nuts. The split nut design eliminates the need for a large housing, significantly reducing the volume of the fixing support components while maintaining the essential fixing function through the simplified pin-and-nut arrangement.

Inventive Principle:
Principle #1Segmentation

3Strength

If multiple materials and complex components are used, then the fixing strength is sufficient, but the manufacturing complexity increases

Engineering Contradiction:
Improvefixing strengthVSAvoidproduction complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The invention combines the functions of the connecting pin, nut, and mounting interface into an integrated fixing support system. The half-nuts are resiliently connected directly to the connecting pin, eliminating the need for separate housings and multiple assembly steps. This merging of components simplifies manufacturing while maintaining fixing strength through the direct structural connection and proper material selection for the pin and half-nuts.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to a fixing support for anchoring a supporting frame of a sanitary facility, in particular of a toilet, bidet, washbasin, shower and urinal, to masonry, which comprises a connecting pin (10) adapted to be inserted into the supporting frame (2) and to be locked in the supporting frame (2), whereby the connecting pin (10) is coupled to an anchor screw (13) for fixing to the masonry. The connecting pin (10) is provided at its rear end with a longitudinal split nut (12) which passes through the cavity of a nut lock (14) and which is on its inner side provided with nut sections (1200) with a nut thread parts (12000) into which an outer thread (130) on a shank (131) of the anchor screw (13) fits, whereby the nut lock (14) is reversibly displaceable in the direction of the length of the split nut (12) and the split nut (12) is on its outer surface provided with inclined ramps (1201) adapted to control the clamping of the split nut (12) around the anchor screw (13).
