Door Assembly Adapter Profile for Continuous Edge and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing door systems face challenges in achieving a continuous, visually appealing edge profile due to different profile heights for side panels and door frames, leading to increased manufacturing costs and complexity, especially when using plastic profiles with various decorations.
Innovation Solution
The door system utilizes an existing wing profile as a base profile for the fixed side part, with an adapter profile bridging the air gap between the sash and threshold, allowing the wing profile to form the lower crossbar and creating a continuous visible edge, while also providing additional sealing and drainage functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If different profiles with different heights are used for side panel and door frame, then the door leaf can move freely on the threshold, but the edge heights differ creating visual disruption
Solution Approach 1:
An adapter profile is introduced as an intermediary element between the base profile and the sash profile on the side panel. This adapter profile has a first section that connects to the base profile and a second section that connects to the sash profile, thereby mediating the height difference and creating a continuous visible edge while preserving the air gap for door movement
Solution Approach 2:
The side panel profile is segmented into three distinct parts: the base profile (first profile), the adapter profile (second profile), and the sash profile (third profile). This segmentation allows each part to fulfill its specific function - the base profile provides structural support, the adapter bridges the height difference, and the sash profile maintains the air gap for door movement
2Shape
If special profiles are manufactured to achieve continuous edge finish, then aesthetic appearance is improved, but manufacturing costs and complexity increase significantly
Solution Approach 1:
The adapter profile serves multiple functions: it creates the continuous visible edge for aesthetics, bridges the height difference between base and sash profiles, enables the use of standard sash profiles without modification, and provides a platform for foil finishing. This multi-functionality eliminates the need for numerous special-purpose profiles
Solution Approach 2:
Instead of manufacturing different profiles with different heights for various sash profile types, the invention changes the parameter approach by using a universal adapter profile that can accommodate different sash profile types through adaptive connection methods, thereby standardizing the solution across multiple applications
3Shape
If adapter profiles are used to bridge the air gap, then continuous visible edge is achieved, but additional profiles and colors must be manufactured and stocked
Solution Approach 1:
The adapter profile is designed as a universal component that can work with multiple types of sash profiles and base profiles. By providing connection options for different profile types and allowing foil finishing to match various colors, the system reduces the need for numerous specialized adapter profiles

AI summary
A profile system for a door assembly (1) with a frame, a door leaf (3) and a fixed side panel (2, 4), wherein the side panel (2, 4) and the door leaf (3) each have a profile frame in which a panel (31, 32) is enclosed, comprises at least: - a leaf profile (10) for forming the profile frame of the door leaf (3), - a frame profile (30) and a base profile for forming the side panel (2, 4) and - a threshold element (40). The leaf profile (10) can be connected to the threshold element (40) via an adapter profile (20), wherein the height of the adapter profile (20) essentially corresponds to the height of an air gap between the threshold element (40) and the door leaf (3).The sash profile (10) has a rebate projection (14) on its side (12) facing the interior of the building, which is to be arranged laterally next to the adapter profile (20) and which extends to below a sash profile underside (13) on which the adapter profile (20) can be mounted.
