Adjustable Mounting Bracket for Flush Plaster Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation support arrangements face challenges in achieving precise positioning and flush integration with masonry surfaces due to tolerances in masonry and installation boxes, leading to tilted arrangements and difficulties in plastering.
Innovation Solution
Incorporating adjustable screws that are rotatably but axially fixed on the installation support, allowing for precise alignment and adjustment relative to the base body, without clamping the support against the base, and using a flexible sealing element to prevent plaster material penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening screws are used to clamp the installation support against the base body, then the installation support is securely fastened, but the positioning accuracy deteriorates due to tolerance accumulation in masonry and installation boxes
Solution Approach 1:
The fastening screw is designed with a two-stage function: initially acting as a positioning element that can be adjusted to achieve precise alignment, and then locked in position to provide secure fastening. This dynamic transformation from adjustable to fixed state resolves the contradiction between positioning accuracy and fastening security.
Solution Approach 2:
The fastening screw serves dual purposes: it both positions the installation support precisely and secures it firmly. By integrating positioning and fastening functions into a single component, the system eliminates the need for separate positioning mechanisms, thereby maintaining positioning accuracy while ensuring reliable fastening.
2Reliability
If the installation support is clamped tightly against the base body, then fastening security is improved, but the ability to adjust position deteriorates
Solution Approach 1:
The fastening screw transitions from an adjustable state during positioning to a locked state for secure fastening. This dynamic behavior allows the system to achieve both position adjustment capability and fastening security at different stages of installation.
Solution Approach 2:
The positioning adjustment is performed preliminarily before final fastening. The fastening screw is first used to achieve precise positioning, then locked in place to provide secure fastening. This sequence of preliminary positioning followed by final securing resolves the contradiction between adjustability and fastening security.
3Manufacturing precision
If multiple components are used to achieve precise positioning, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The fastening screw is designed to perform multiple functions: positioning, alignment, and secure fastening. By making the fastening screw a multi-functional component, the system achieves precise positioning without adding separate positioning mechanisms, thereby maintaining simplicity while improving positioning accuracy.
Solution Approach 2:
The positioning function and fastening function are merged into a single fastening screw component. This consolidation eliminates the need for additional positioning elements, reducing device complexity while maintaining positioning accuracy through the screw's adjustable and lockable characteristics.

AI summary
The invention relates to a mounting bracket arrangement comprising a frame-like mounting bracket which has a sleeve-like receptacle designed to receive and hold an insert element and which has a projecting front edge, and at least one plastering flange on the mounting bracket with through holes for fastening screws, wherein the plastering flange adjoins the receptacle laterally and is set back from the front edge of the receptacle, wherein the mounting bracket can be inserted into a recessed installation space of a base body with a substantially flat surface and can be fixed in a plastering position, and the frame-like mounting bracket is designed to be plastered in the installation space in the base body in the plastering position, leaving the receptacle exposed, at the same height as the substantially flat surface, wherein plastering material covers the plastering flange and extends to the front edge of the receptacle.According to the invention, at least one fastening screw is designed as an adjusting screw, which is rotatably but axially fixed mounted on the mounting bracket, and at least one adjusting screw is arranged by which the mounting bracket can be freely adjusted relative to the base body for position adjustment in the plastering position and can be locked in the desired position.
