Universal Concealed Door Frame for Reversible Swing Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional concealed door frame systems require precise measurement and custom fabrication, necessitating multiple profile models and complex planning, leading to high manufacturing and storage costs, and limiting flexibility in door configurations.
Innovation Solution
A universal frame system with a single profile design that can accommodate different door opening configurations using straight cuts, featuring a projection for alignment, adapters for conventional hinges, and a connecting element for secure assembly, allowing flexibility in door swing directions without requiring off-site preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple door frame profile models are used to accommodate different door swing directions and opening types, then the door frame can be properly configured for specific installations, but the device complexity and inventory management complexity increase significantly
Solution Approach 1:
The patent implements a universal door frame profile that can accommodate both inward and outward opening doors, as well as both right and left door swings, through a single profile design. The profile includes a symmetric hinge attachment section with positioning elements that work identically regardless of door configuration, eliminating the need for multiple specialized profile models while maintaining full adaptability to different door setups
2Adaptability or versatility
If multiple door frame profile models are required for different configurations, then proper door installation is achieved, but manufacturing costs and storage costs increase due to the necessity of multiple profile models
Solution Approach 1:
The universal profile design consolidates multiple configuration-specific profiles into a single standardized component that serves all door configurations through its symmetric hinge attachment mechanism, directly reducing inventory variety and associated manufacturing and storage costs
3Ease of manufacture
If miter-cutting is used to connect profile sections at 90-degree angles, then the frame sections can be joined, but the measurement and execution complexity increases compared to straight cuts
Solution Approach 1:
Instead of cutting the profile sections at complex 45-degree miter angles to achieve 90-degree frame corners, the patent inverts the approach by using straight transverse cuts on all profile sections and achieving the 90-degree corner connections through the design of the connecting elements and positioning features, thereby simplifying the cutting operation while maintaining proper frame geometry

AI summary
The present invention relates to a universal frame for concealed doors, designed to accommodate inward or outward opening configurations and right- or left-hand door swing without requiring specific profiles. The frame consists of four structural components: a rectangular-section profile (1) with an internal channel (8) for inserting hinge adapters (5), a connecting element (4) that joins the vertical and horizontal profiles (3) without requiring miter cuts, adjustable adapters (5) that allow the use of conventional hinges (6), and a cover (7) that conceals the open spaces of the channel (8). The asymmetrical configuration of the profile (1) enables installation in any direction simply by flipping it along its transverse axis. This solution simplifies installation, reduces manufacturing and storage costs, and provides greater flexibility for the installer by allowing the use of any hinge (6) available on the market.
