Door Frame Stop Profile with Adjustable Securing Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door frame sets are not flexible enough to accommodate doors of different types and wall configurations, requiring tailor-made solutions that can be expensive and inconvenient, especially when it comes to securing screws in the wall opening.
Innovation Solution
A door frame set with a stop profile and securing means that can be positioned and secured in two configurations – for doors that can be pulled or pushed open – using a securing profile that can be attached to a stop profile without the need for screws, allowing for greater flexibility and compatibility with various door and wall types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional door frame sets with wooden or aluminium profiles are used, then doors can be hung in wall openings, but each door type (pushed or pulled open) requires a different door frame set, reducing flexibility and increasing cost
Solution Approach 1:
The stop profile is designed with a universal securing body that can accommodate both pushed-open and pulled-open door configurations using the same profile design. The securing means can be positioned at different locations on the stop profile to support different door opening directions, eliminating the need for separate door frame sets for different door types.
Solution Approach 2:
The door frame set incorporates adjustable positioning capabilities where the securing means can be located at different positions on the stop profile. This dynamic adaptability allows the same stop profile to function with both pushed-open and pulled-open doors by simply changing the securing means position, rather than requiring fixed, different designs for each door type.
2Reliability
If screws are used to secure the door frame set in the wall opening, then the door frame set can be firmly fixed, but covering elements are required to obscure screws and cover holes, increasing device complexity
Solution Approach 1:
A securing profile acts as an intermediary element between the stop profile and the wall opening. This securing profile is designed to be inserted into the wall opening and secured there, providing a mounting surface for the stop profile without requiring visible screws or covering elements. The securing profile mediates the connection, eliminating the need for aesthetic covering components while maintaining secure fixation.
3Ease of manufacture
If the stop profile is designed for a specific door opening direction, then the door frame set can be simplified, but it cannot be reused for different door orientations, reducing adaptability
Solution Approach 1:
The stop profile is segmented into functional zones with the securing body positioned to allow flexible placement of securing means. This segmentation enables the same profile design to be used for different door orientations by simply changing where the securing means is attached, rather than requiring different profile designs for each orientation.
Solution Approach 2:
The stop profile design incorporates universal features that allow it to serve multiple door opening directions. The securing body and its positioning are designed to accommodate both pushed-open and pulled-open configurations, making the profile universally applicable across different door orientations without requiring redesign.

AI summary
The present invention relates to a door frame set for hanging a door (1) in a wall opening (2), comprising a stop profile (3), which comprises, at one end, a stop (3a), and comprises, at another end, a face (3b) which is at right angles to the stop face and securing means by means of which the stop profile (3) can be secured in the wall opening (2) both in a first position, in which the stop (3a) forms a stop face for a door (1) which can be pulled open, and in a second position, in which the stop (3a) forms a stop face for a door (1) which can be pushed open. The present invention also relates to a door assembly comprising such a door frame set.
