Sliding Fastening Tab Mounting Frame for Sanitary Fittings

Solution Overview

Problem

Existing mounting systems for sanitary fittings suffer from weakened mechanical strength due to stress concentration at bending points, compromising overall stability.

Innovation Solution

A mounting system featuring a hollow profile with a slidable fastening tab that moves between a starting and mounting position, allowing flexible adaptation to mounting situations without impairing mechanical stability, using a guide receptacle and snap connections for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the fastening tab is bent about a bending point to provide pivotability, then the fastening tab can be pivoted relative to the connecting piece, but stress concentration occurs at the bending point which weakens the mechanical strength

Engineering Contradiction:

Improvepivotability of fastening tabVSAvoidmechanical strength of fastening tab

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The fastening tab is divided into two separate components: a connecting piece with a guide receptacle and a separate fastening tab. The fastening tab slides within the guide receptacle rather than being bent, eliminating stress concentration while maintaining pivotability. This segmentation allows independent optimization of each component's function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fastening tab is designed to be movable within the guide receptacle, transitioning from a static bent configuration to a dynamic sliding mechanism. This allows the fastening tab to pivot relative to the connecting piece through controlled movement along a defined path, avoiding permanent deformation and stress concentration.

Inventive Principle:

Principle #15Dynamics

2Strength

If the fastening tab is made fixed to ensure mechanical strength, then structural stability is improved, but flexibility to adapt to different mounting situations is reduced

Engineering Contradiction:

Improvemechanical strength of fastening tabVSAvoidflexibility to mounting situations

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The fastening tab is designed to be movable within the guide receptacle, transitioning from a static bent configuration to a dynamic sliding mechanism. This allows the fastening tab to pivot relative to the connecting piece through controlled movement along a defined path, avoiding permanent deformation and stress concentration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The guide receptacle acts as an intermediary component that guides and constrains the movement of the fastening tab. This intermediary structure enables the fastening tab to move and adapt to different mounting situations while maintaining proper alignment and avoiding uncontrolled deformation that would compromise strength.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the fastening tab is made long to extend beyond the hollow profile for fastening, then fastening capability is improved, but the risk of stress concentration and mechanical weakness increases

AI summary

A mounting system for fastening a sanitary fitting having a mounting frame having at least one hollow profile, the side walls of which define an internal space The frame has an end face at the end thereof, and the frame has at least one bearing structure for mounting a sanitary fitting. At least one fastening unit is provided with a support element with a guide receptacle and a fastening tab which is mounted in the guide receptacle so as to slide relative to the support element from a starting position into a mounting position. The support element can be inserted in the internal space of the hollow profile, and, in the mounting position, the fastening tab extends out of the guide receptacle and out of the internal space beyond the end face of the hollow profile.
