Door Cover Profile Offset From Fastening Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing door designs with a gap on the hinge side pose a risk of finger pinching, especially for children, as the gap size changes with the door's pivot, and current solutions do not provide a flexible and effective security enhancement.
Innovation Solution
A door design incorporating a cover profile that is offset from the fastening profile, with a hinge section positioned above and below the door hinge, allowing for adjustable distance and a flat geometric configuration, which partially covers the gap between the door leaf and frame, and includes a breaking groove for easy customization around the door hinge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover profile is added to cover the hinge-side gap, then safety against finger pinching is improved, but device complexity increases
Solution Approach 1:
The cover profile is divided into a first cover portion and a second cover portion that can be independently positioned and adjusted. This segmentation allows each portion to be optimized for specific functions (covering the gap vs. adjusting distance) while simplifying the overall installation and adjustment process, thereby reducing the operational complexity despite adding safety coverage.
Solution Approach 2:
The distance adjustment mechanism enables the second cover portion to be dynamically repositioned along the fastening profile relative to the door hinge. This dynamic adjustment capability allows the system to adapt to different door configurations and hinge positions, maintaining safety effectiveness while providing flexibility that reduces the need for custom-designed solutions for each scenario.
2Reliability
If the cover profile is positioned close to the door hinge, then coverage effectiveness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The system transitions from a fixed-position cover profile to a dynamically adjustable one. The second cover portion can be repositioned along the fastening profile to achieve optimal coverage of the hinge-side gap, eliminating the need for precise pre-manufacturing positioning. This dynamic adjustment compensates for variations in door and hinge dimensions, maintaining coverage effectiveness without stringent manufacturing precision requirements.
Solution Approach 2:
The position parameter of the cover profile is made variable through the distance adjustment mechanism. By allowing the second cover portion to be repositioned to different locations along the fastening profile, the system can adapt to different door configurations and hinge positions, ensuring effective gap coverage without requiring the cover profile to be manufactured with high precision for a specific fixed position.
3Ease of manufacture
If the cover profile design is simplified for easier manufacture, then ease of manufacture is improved, but adaptability to different door configurations decreases
Solution Approach 1:
The cover profile incorporates a distance adjustment mechanism that provides dynamic positioning capability. This allows a relatively simple, standardized cover profile design to adapt to different door configurations by repositioning the second cover portion along the fastening profile, thereby maintaining ease of manufacture while achieving versatility across various door and hinge configurations.
Solution Approach 2:
The cover profile is designed as a universal component that can be applied to different door configurations. The distance adjustment mechanism enables a single standardized cover profile design to serve multiple functions and adapt to various door widths, hinge positions, and gap sizes, eliminating the need for custom-designed cover profiles for each application while maintaining ease of manufacture.

AI summary
The invention relates to a door comprising a door leaf (202), a door hinge (200), a door frame (201), a fastening profile (100), and a cover profile (101; 500), wherein the door leaf (202) has two main surfaces and two secondary surfaces, the area of each of the main surfaces being many times larger than the area of the secondary surfaces, wherein the door hinge (200) is attached to a lateral end region of the door leaf (202), wherein the door leaf (202) is pivotably connected to the door frame (201) via the door hinge (200), wherein the fastening profile (100) is attached to the door leaf (202) or to the door frame (201), wherein the cover profile (101; 500) is connected to the fastening profile (100), and wherein the cover profile (101; 500) forms a gap between the door leaf and the door frame (201). (202) and the door frame (201) at least partially covers the area adjacent to the side end area, wherein the cover profile (101; 500) covers a hinge section (108;501) which is arranged exclusively above and below the hinge (200), wherein the hinge section (108; 501) is arranged in a horizontal direction parallel to the main surfaces and offset from the fastening profile (100).
