Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steel frame doors with fire-break systems face installation challenges due to fixed sizes, leading to poor appearance and potential damage during construction, and existing telescopic frames lack sufficient adjustability and mechanical resistance for varied wall thicknesses.
Innovation Solution
A telescopic wall-clamping frame unit made of steel with a pressure angle and wall clamp, allowing for adjustable installation over 65mm, enhancing mechanical resistance and enabling secure fitting without screws, suitable for steel frame doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed size wall-clamping frames are installed before finishing work, then installation is simpler, but the door frame may receive blows, stains, scratches or other imperfections during construction
Solution Approach 1:
The wall clamp incorporates a telescopic mechanism with movable elements that allow dynamic adjustment of the clamping length. The clamp can extend and retract to accommodate different wall thicknesses and provide protection during construction, then be adjusted to a compact form for final installation. This dynamic capability enables the frame to adapt to construction conditions while maintaining protection capabilities.
2Ease of manufacture
If fixed size wall-clamping frames are used, then installation process is simplified, but they cannot adapt to varied wall thicknesses
Solution Approach 1:
The wall clamp incorporates a telescopic mechanism with movable elements that allow dynamic adjustment of the clamping length. The clamp can extend and retract to accommodate different wall thicknesses and provide protection during construction, then be adjusted to a compact form for final installation. This dynamic capability enables the frame to adapt to construction conditions while maintaining protection capabilities.
Solution Approach 2:
The telescopic mechanism allows the wall clamp to change its dimensional parameters, specifically the clamping length, to match different wall thicknesses. By adjusting the extension of the telescopic elements, the clamp can be configured for various wall dimensions without requiring multiple fixed-size frames, thus simplifying the installation process while maintaining adaptability.
3Ease of manufacture
If telescopic frames with small adjustment range are used, then manufacturing is simpler, but they cannot cover wide wall thickness variations
Solution Approach 1:
The wall clamp is divided into multiple telescopic segments or elements that can extend and retract relative to each other. This segmentation allows the clamp to achieve a large overall adjustment range by combining the movement of multiple segments, while each individual segment maintains a manageable and simple manufacturing complexity. The modular segmented structure enables extended functionality without proportionally increasing manufacturing difficulty.
4Object-affected harmful factors
If wall clamps are installed before finishing work to protect the frame, then protection is provided, but installation time increases due to verification of fixed measures

AI summary
In order to obtain a regulation of over 65 millimetres and improve the installation of the product, the invention consists of a unit formed by a frame, to which an angle pressure is attached, consisting of two steel profiles joined at a minimum distance by means of welding points. The internal profile is L-shaped and the internal one is similar, with an end fold. This pressure angle serves to guide, house and secure the wall clamp correctly by means of the pressure it exerts on it, so the unit is coupled to a variable thickness wall and creates a space to place various insulating materials. We have planned a version in which the frame and one piece of the pressure angle form a single element attached to the second piece of the pressure angle with screws, thus supporting the wall clamp as in the first version.
