Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cold forming or extrusion processes are used to manufacture metal frame profiles, then the structural integrity and insulation performance are improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The frame is divided into separate flat metal frame elements that are assembled together using adhesive tapes and welding studs, rather than manufacturing complex extruded profiles as single pieces. This segmentation simplifies manufacturing while maintaining structural integrity through the assembly connection system.
Solution Approach 2:
The invention uses a composite construction combining flat metal frames with insulating bodies positioned between them in sandwich construction. This approach achieves thermal insulation performance without requiring complex extruded profiles, simplifying the manufacturing process while maintaining insulation effectiveness.
2Temperature
If complex extruded profiles are used, then the insulation performance is improved, but the assembly difficulty and time increase
Solution Approach 1:
The frame system is segmented into separate flat metal frame elements with insulating bodies, which are assembled using simple adhesive tapes and welding studs. This segmentation reduces assembly complexity compared to installing complex extruded profiles, while the insulating bodies maintain thermal insulation performance.
Solution Approach 2:
Adhesive tapes serve as intermediaries to simplify the connection between flat metal frame elements and insulating bodies, making assembly easier. The welding studs provide additional mechanical connection while maintaining simplicity in the assembly process.
3Productivity
If standardized manufacturing processes are used, then the production efficiency is improved, but the design versatility decreases
Solution Approach 1:
The frame system uses standardized flat metal frame elements and insulating bodies that can be assembled in various configurations. This segmentation allows efficient standardized production of components while enabling versatile design adaptations by changing the arrangement and dimensions of the modular elements.
Solution Approach 2:
The flat metal frame elements and insulating bodies serve multiple functions: structural support, thermal insulation, and adaptability to different window and door configurations. This universality allows the same basic components to be used in various designs, maintaining production efficiency while achieving design versatility.

Function Achieved in This Case
This method simplifies the production and assembly of window and door elements, reducing costs and enabling versatile designs, while maintaining structural integrity and aesthetic appeal.
Implementation Method 1
The end faces of the insulating body are provided with adhesive and/or adhesive tapes for fixing the supporting metal flat frames
Implementation Method 2
the attachment of the metal flat frames to the insulating body consists in the metal flat frames being equipped with welding studs and the insulating body being equipped with corresponding blind holes into which the welding studs can snap for fixation
Implementation Method 3
it is common practice to use so-called insulating profiles, so that the outer metal frame surface is thermally insulated from the inner metal frame surface
