Rotating Clamping Angles for Frame Wall Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing frames to walls, particularly using PU foam, are time-consuming, dependent on temperature and humidity, and can result in shifting or warping frames due to foam expansion, leading to additional costs and time for removal and replacement.
Innovation Solution
A device comprising a retaining plate with rotationally fixed clamping angles, each with planar clamping elements and connecting pieces, allows for quick and simple securing of frames to walls by adjusting the span width of the clamping angles to achieve a sufficient clamping force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If PU foam is used for securing frames to walls, then the frame can be easily installed, but the installation time increases due to waiting for foam curing
Solution Approach 1:
The patent extracts and eliminates the PU foam curing step from the installation process by using a mechanical clamping device with wall anchors that provide immediate securing force, replacing the time-dependent chemical curing process with an immediate mechanical fastening system
Solution Approach 2:
The patent replaces the chemical-based PU foam securing system with a mechanical clamping device consisting of clamping angles, a retaining plate, and wall anchors, which provides immediate mechanical securing without requiring chemical curing time
2Ease of manufacture
If PU foam is used for securing frames, then the frame can be installed without additional hardware, but the securing quality becomes dependent on temperature and humidity
Solution Approach 1:
The patent replaces the environmentally sensitive PU foam chemical bonding system with a temperature-independent mechanical fastening system using wall anchors and clamping elements that provide reliable securing regardless of thermal or humidity conditions
Solution Approach 2:
The patent changes the securing mechanism from a chemically-based process (PU foam) whose properties vary with temperature and humidity to a mechanically-based process whose performance is independent of these environmental parameters
3Ease of manufacture
If PU foam is used for securing frames, then the installation process is simple, but the frame may shift or warp due to foam expansion
Solution Approach 1:
The patent extracts and removes the expansion mechanism from the securing process by replacing PU foam with a rigid mechanical clamping system that maintains constant dimensional stability and prevents frame shifting through fixed geometric constraints
Solution Approach 2:
The patent applies preliminary anti-action by using clamping elements that preemptively counteract any potential frame movement or warping through continuous mechanical constraint, preventing the instability problems caused by foam expansion
4Ease of manufacture
If a clamp with round or tubular connecting elements is used for securing frames, then the device can be assembled, but the handling becomes difficult due to orientation issues
Solution Approach 1:
The patent applies asymmetry by using planar clamping elements with specific geometric orientations that provide intuitive alignment and eliminate handling difficulties associated with symmetric round or tubular connecting elements

AI summary
A device for securing frames, including a retaining plate and two clamping angles, the clamping angles being retained on the retaining plate so they can shift in relation thereto. To ensure simple handling, the angles are arranged on the retaining plate rotationally fixed and each includes at least one clamping element and at least one connecting piece. Methods are included for securing a frame to a wall, whereby one angle is connected to a retaining plate that is secured to an inner side of the frame. To secure the frame simply, it is inserted into a wall opening and a second angle is connected to the plate in a rotationally fixed manner across from the first angle, after which the first and second angles are connected using at least one adjusting means and a span width is reduced until a sufficient clamping force on the wall is reached.
