Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If different profile dimensions are used for varying window widths, then the structural integrity is maintained, but the manufacturing complexity and material costs increase
Solution Approach 1:
The frame is divided into modular components: a universal basic profile and width-adjustable additional elements. These segments can be combined in different configurations to achieve various window widths while maintaining consistent basic profile dimensions, thereby reducing manufacturing complexity while preserving structural integrity
Solution Approach 2:
The basic profile is designed with universal dimensions and features that can accommodate multiple window widths. The same basic profile serves different functions by combining with varying numbers of additional elements, reducing the need for multiple specialized profile types and simplifying manufacturing processes
2Strength
If larger profile cross-sections are used for wider windows, then the structural strength is maintained, but the thermal insulation performance deteriorates
Solution Approach 1:
Instead of using a single large cross-section profile, the frame is segmented into a standard basic profile combined with additional elements. This segmentation allows maintaining the thermal performance of the standard basic profile while achieving the required structural strength through the combined modular structure
Solution Approach 2:
The additional elements are strategically positioned to provide structural reinforcement only where needed for wider windows, while the majority of the frame retains the standard basic profile with optimal thermal insulation properties. This localized reinforcement approach maintains overall thermal performance
3Ease of manufacture
If thicker laminated glass panes are used for standard dimensions, then the manufacturing simplicity is maintained, but the material costs and weight increase
Solution Approach 1:
The universal basic profile with standard dimensions can be used across multiple window width applications, allowing consistent manufacturing processes and standard glass thicknesses. This universality maintains manufacturing simplicity while reducing material costs by avoiding the need for custom-thick glass for each window size variation

Implementation Method 1
filled in the associated formwork with a foaming, hardening, heat-insulating material
Implementation Method 2
filled in the associated formwork with a foaming, hardening, heat-insulating material
Implementation Method 3
the thin-walled elements used in the heat-insulating, translucent covering of the opening have surfaces that delimit the cavity they form and, due to the small cross-sectional thickness of the material forming them, they do not represent elements that conduct heat and form thermal bridges

AI summary
The technical solution relates to the field of translucent building structures arranged in openings of buildings and facilities, preferably windows, but it can also be used in the construction of doors, for example, balcony doors. The object underlying the invention is to create a fully factory-assembled translucent opening covering, which includes universal additional elements of the frame or sash that allow the frame or sash to be manufactured simultaneously in the sheathing. Uniform basic profiles with a fixed cross-section are used for all standard dimensions, and changes in the standard size of their cross-section width are compensated for by modular additional elements. The technical result lies in increasing the level of technological sophistication of heat-insulating, translucent opening coverings.This is achieved in that the heat-insulating, translucent covering of the opening comprises glazing as well as a frame and a sash connected by a window fitting, the frame and sash being formed from the lining layers forming their internal cavities, which are connected to one another and filled with a hardening, heat-insulating foam material in the associated formwork, characterized in that the distal lining layers of the frame and the mutually facing lining layers of the frame and sash are designed to be composable across the width of their cross-section and comprise longitudinally modular basic and additional elements forming them, which are coherent around the circumference of their cross-section. Furthermore, the modular longitudinal additional elements of the sash can be arranged on the side opposite the modular additional elements of the frame.The longitudinal modular add-on elements can have a tenon and groove joint to form a circumferentially closed cross-section of the frame or sash. The distal (from Latin disto - to be distant), i.e., located far, and the proximal (Latin proximus - the nearest), i.e., located closest, modular longitudinal add-on elements of the frame are located, respectively, on the outer and inner perimeters of the frame, on the side of the connecting lining layer. To increase the width of the heat-insulating, translucent covering of the opening, it is connected to additional, modular, longitudinal basic add-on elements of the frame and sash, with their width equal to or less than the width of the longitudinal modular basic add-on elements. The lining layer can be made of thin-walled or hollow material and filled with thermosetting, heat-insulating foam material in the removable accompanying formwork.The cavities of the frame and the sash can be of the same volume, and a longitudinal reinforcing element with a continuous cross-section can be arranged in the cavity of the frame.
