Angled Mounting Bracket for Multi-Layer Wall Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting brackets for windows or doors in multi-layer walls face challenges due to the difficulty in accessing the space between wall layers, which are often filled with insulation materials, making direct and firm support impossible, and requiring great effort and skill for installation.
Innovation Solution
A mounting bracket design featuring a first leg for wall contact, a second leg at a right angle for building element support, with inclined screw openings and a screw head bearing surface on the outside of the second leg, along with positioning and anti-rotation elements, allowing for easy and precise alignment and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional angle brackets are mounted in the space between the two walls, then the building element can be attached to the opening, but the installation requires considerable effort and great skill due to difficult accessibility
Solution Approach 1:
The mounting bracket is divided into two separate legs: a first leg for mounting against the wall and a second leg for mounting the building element. This segmentation allows each leg to be optimized for its specific function and enables simpler installation by reducing the need to access the difficult-to-reach space between walls.
Solution Approach 2:
The second screw opening is positioned in an inclined section that forms a screw head bearing surface on the outside of the second leg, rather than requiring access to the interior space between walls. This dimensional repositioning moves the fastening operation to an externally accessible location, significantly improving ease of installation.
2Ease of operation
If the second screw opening is positioned in an inclined section with screw head bearing surface on the outside of the second leg, then the installation becomes simpler and more accessible, but the structural design becomes more complex
Solution Approach 1:
The inclined section and screw head bearing surface are integrated directly into the second leg as a single structural feature, combining the positioning and support functions into one element. This merging simplifies the overall design while achieving the desired ease of installation.
Solution Approach 2:
The inclined section with screw head bearing surface is pre-formed as part of the second leg during manufacturing, so that when the mounting bracket is installed, the screw head automatically finds its bearing surface without requiring additional positioning steps or complex alignment procedures.
3Reliability
If the mounting bracket uses a diagonal screw connection through both legs, then stable fixation is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The diagonal screw connection serves multiple functions simultaneously: it secures the first leg to the wall, attaches the second leg to the building element, and provides structural stability. This multi-functionality reduces the need for additional fasteners or complex assembly steps, simplifying manufacturing while ensuring reliable fixation.
