Adjustable Door Fitting with Movable Distance Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door fittings require different configurations for various door and frame offsets, leading to inefficiencies in minimizing air or substance penetration.
Innovation Solution
A door fitting with a rotatable body and a moveable distance element between a support plate and the body, allowing adjustment of the offset to achieve optimal sealing pressure, compatible with multiple door types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed offset fitting is used, then the structure is simple, but it cannot accommodate different door and frame offsets
Solution Approach 1:
The distance element is made movable between a first position and a second position, allowing the offset between the support plate and body to be dynamically adjusted. This enables the fitting to adapt to different door and frame offsets while maintaining a relatively simple overall structure.
Solution Approach 2:
The offset parameter of the fitting is changed by moving the distance element between different positions. The distance element provides a first offset in the first position and a second offset in the second position, allowing the fitting to be adapted to different door configurations without changing the basic fitting structure.
2Reliability
If the body abuts the door directly, then the structure is simple, but air penetration cannot be minimized for doors with different offsets
Solution Approach 1:
The distance element acts as an intermediary component between the support plate and the body. By adjusting the position of this intermediary element, the offset between the support plate and body can be controlled, ensuring proper sealing pressure for doors with different offsets while maintaining structural simplicity.
3Reliability
If different fittings are used for different offsets, then sealing can be optimized, but the quantity of fittings needed increases
Solution Approach 1:
A single fitting design incorporates a movable distance element that can be positioned in multiple locations, allowing one fitting type to serve multiple offset requirements. This universal design eliminates the need to stock multiple different fitting types for different door configurations.
4Adaptability or versatility
If the distance element is made movable, then adaptability to different offsets is achieved, but the device complexity increases
Solution Approach 1:
The fitting is segmented into distinct components: the body, the support plate, and the movable distance element. This segmentation allows the distance element to be independently moved between positions without complicating the other components, achieving adaptability with minimal added complexity.

AI summary
The present disclosure relates to a fitting (1) for arrangement to a door and a door frame. The fitting (1) comprises a body (3), a first part (4), and a support plate (6) arranged at a door facing side of the body. The fitting is configured to abut the door when arranged thereto and comprises a distance element (5) in-between the support plate and the body which sets an offset between the support plate and the body. The distance element is moveable between different positions providing different offset between the body and the support plate. This arrangement minimizes the penetration of air or other substance through the door due to an offset between the door and door frame and can be used on different types of doors with different offsets.
