Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If connecting webs are used to connect frame parts, then structural strength is improved, but heat radiation increases creating thermal bridges
Solution Approach 1:
The patent removes the connecting webs from the frame structure. By extracting this heat-conducting element, the thermal bridge is eliminated while the frame parts are connected through alternative means (snap connections with adhesive) that do not create heat radiation pathways.
Solution Approach 2:
The patent introduces adhesive as an intermediary material to connect frame parts. This adhesive layer replaces the metal connecting webs and provides a thermal break, preventing heat radiation while maintaining structural connection through mechanical snap connections reinforced by the adhesive bond.
2Stability of the object's composition
If complex bending processes are used to connect railing parts and insulating frame parts, then form-fitting connection is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the frame into separate modular parts (railing parts, insulating frame parts) that are connected through simple snap connections rather than requiring complex bending processes. This segmentation allows each part to be manufactured independently and assembled easily.
Solution Approach 2:
The patent replaces complex mechanical bending processes with simpler snap connection mechanisms. Instead of bending metal parts to achieve form-fitting connections, the invention uses elastic snap connections that engage through simple insertion movements, significantly simplifying the manufacturing process.
3Ease of manufacture
If snap connections are used without adhesive, then production simplicity is improved, but connection reliability decreases
Solution Approach 1:
The patent combines two connection methods: mechanical snap connections and adhesive bonding. The snap connections provide immediate mechanical engagement and alignment, while the adhesive reinforces the bond and ensures long-term reliability, creating a hybrid connection system that maintains both simplicity and reliability.
Solution Approach 2:
The snap connections perform preliminary alignment and positioning of frame parts during assembly. This preliminary action ensures proper orientation and contact surfaces are correctly positioned before the adhesive sets, allowing the adhesive to bond effectively and ensuring connection reliability without compromising production simplicity.

Implementation Method 1
an elastic or viscous material, preferably with less than 70 Mooney, is provided, which presses on at least one of the engaging parts in the direction of engagement and thus ensures snapping
Implementation Method 2
an elastic or viscous material, preferably with less than 70 Mooney, is provided
Implementation Method 3

AI summary
The profile (1) has engagement parts (8, 9) elastically formed at a frame (2, 3) or insulating frame part (4). Ends, which are facing freely from the frame part, of the parts are connected with connecting bars (10, 11), and form a snap connection with opposite engagement parts (6, 7). An elastic or viscous material (15) with less than 70 Mooney is pressed on the latter parts in an engagement direction. The material is formed from an elastic or viscous adhesive in form of adhesive bead, in a hardened condition, where the bead is supported at a support surface (8') of the latter parts. An independent claim is also included for a method for manufacturing a frame profile.
