Self-Clamping Adapter for Door Profile Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door fitting technologies require extensive pre-measurement and customization, limiting adaptability and adjustability during installation, and often necessitate complex preparation like drilling and milling, which reduces efficiency and makes on-site corrections difficult.
Innovation Solution
A door profile with a self-clamping adapter system that allows door fittings to be easily mounted in a U-shaped channel with clamping ribs, enabling quick and efficient installation without pre-drilling, and allowing for adjustments and corrections on-site, using a clamping plate that rotates to secure the adapter in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If door fittings are fixed using bolts or screws in a concealed hinge arrangement, then the hinge can be invisibly incorporated in a wall, but adjustment is difficult and pre-measurement is essential
Solution Approach 1:
The hinge system transitions from a static fixed arrangement to a dynamic adjustable one through the introduction of a regulating screw that enables controlled movement of the hinge leaf relative to the fixing plate, allowing post-installation adjustments while maintaining concealed appearance
Solution Approach 2:
The system incorporates self-adjustment capabilities through the regulating screw mechanism that allows users to manually adjust the hinge position without requiring disassembly or complex tools, enabling self-correction of installation errors
2Manufacturing precision
If door fittings are custom-made to specific measurements, then precise fit is achieved, but installation time increases and on-site adaptability decreases
Solution Approach 1:
The hinge system is divided into modular components (fixing plate, hinge leaf, regulating screw) that can be manufactured separately with standard dimensions and assembled on-site, eliminating the need for custom-made units while maintaining precise fit through the adjustment mechanism
Solution Approach 2:
The fixing plate is pre-equipped with adjustment features and mounting holes that enable quick installation and subsequent regulation, allowing standard components to be prepared in advance rather than requiring custom fabrication for each installation
3Adaptability or versatility
If multiple screw operations are required for adjustment, then limited adjustment is possible, but the process becomes complex and time-consuming
Solution Approach 1:
The adjustment function is extracted as a separate, dedicated mechanism (regulating screw) independent of the mounting screws, allowing adjustment operations to be performed separately and simplifying the overall process by dedicating specific components to specific functions
4Measurement precision
If door profiles are permanently adjusted to measurements, then precise positioning is achieved, but error correction becomes difficult
Solution Approach 1:
The hinge positioning system transitions from a permanent fixed arrangement to a dynamic adjustable one, allowing the hinge leaf to be repositioned relative to the door profile after installation through the regulating screw mechanism, enabling error correction without permanent modification

AI summary
The present invention relates to a door profile, comprising a wall profile and a fitting profile, wherein the fitting profile comprises a substantially U-shaped channel, which U-shaped channel comprises two upright ribs and a connecting rib, wherein the U-shaped channel comprises at least one clamping rib on one of the upright ribs; the door profile further comprising at least one self-clamping adapter, the adapter comprising a receiving body wherein the receiving body comprises at least one clamping element, and wherein the clamping element comprises a clamping plate with a width profile dimensioned to fit between the clamping rib and the opposing upright rib, and with a length profile dimensioned not to fit between the clamping rib and the opposing upright rib, the clamping plate being rotatable relative to the adapter; and wherein a substantially flat slot is defined between said clamping rib and the connecting rib suitable for fixedly clamping said clamping plate. Further aspects relate to a self-clamping hinge and a self-clamping adapter.
