Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If basic construction profiles and accessories are used for door frames and door leaves, then manufacturing simplicity is maintained, but diversified thermal insulation cannot be achieved
Solution Approach 1:
The profile is divided into multiple hollow chambers (first, second, and third chambers) separated by partition walls, with each chamber capable of containing different thermal insulation materials. This segmentation allows diverse thermal insulation configurations using the same basic profile structure.
Solution Approach 2:
Different regions of the profile (different chambers) can be filled with different thermal insulation materials tailored to specific thermal insulation needs, while the overall profile structure remains standardized. This enables localized optimization of thermal insulation without changing the entire profile design.
2Temperature
If thin-wall profiles with multiple chambers are used, then thermal insulation is improved, but manufacturing complexity increases
Solution Approach 1:
The extrusion process divides the profile into multiple chambers during manufacturing, allowing complex thermal insulation structures to be created through a single extrusion operation rather than post-manufacturing assembly, thereby maintaining manufacturing simplicity.
Solution Approach 2:
The same thin-wall profile structure with standardized chambers and connection mechanisms can be used across different door and frame applications, enabling mass production with consistent thermal insulation performance while reducing per-unit manufacturing complexity.
3Adaptability or versatility
If profile spacers with multiple sockets are used, then connection versatility is improved, but component complexity increases
Solution Approach 1:
The profile spacer incorporates multiple types of sockets (first, second, and third sockets) in a single standardized component, enabling it to connect with various elements (transom bars, door leaves, frame elements) without requiring different spacer designs for different applications.
Solution Approach 2:
Instead of creating different connector components for different connection needs, the invention inverts the approach by integrating multiple connection capabilities into a single spacer component, simplifying the overall system through component consolidation.

AI summary
The subject of the invention is the structural connection of door leaf and door frame, the task of which is to ensure diversified thermal insulation depending on the needs while applying the same base profiles of frame and door leaf. The structural connection of door leaf and door frame, is comprised of a thin-wall frame profile and a thin-wall door leaf profile composed of a dimensional compound profile circumflexing the glazed panel secured at its perimeter with a thermal insulating insert and sealed on one side of the glazed panel with an external panel gasket and with an internal pane gasket pressed by a glazing strip on the other side. The thin-wall profile (3) of the frame (2) has three closed chambers (9), (10), (11), where the internal chamber (10) has opposite trapezoid sockets (12), (12') for the fixed connection with trapezoid protrusions (13), (13') of the spacers (14), (15) while the thin-wall profile (4) of the door leaf (1) has three closed chambers (16), (17), (18), while the internal chamber (17) has trapezoid sockets (19), (19') for the fixed connection with trapezoid protrusions (20), (20') of the profile spacers (21), (22), while in the space (23) between the door leaf (1) and the frame (2), masking gaskets (24), (24') are located, the profile, trapezoid protrusions of which (25), (25') are inserted into the rhombus-shaped sockets (26), (26') of the profile spacer (15). (21), while between the door leaf (1) and frame (2) closing strips have been placed (8), (8').
