Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate insulating block and sash frame seal are used, then assembly is more complex, but manufacturing precision can be improved
Solution Approach 1:
The insulating block and sash frame seal are merged into a single integrated component. The insulating block is formed as an integral part of the sash frame seal, eliminating the need for separate assembly steps while maintaining both thermal insulation function and sealing function. This integration resolves the contradiction by achieving both simplified assembly and consistent manufacturing precision through a unified production process.
Solution Approach 2:
The integrated component serves multiple functions simultaneously: it provides thermal insulation, seals the air gap between window frame and sash frame, and maintains structural integrity. This multi-functionality approach allows a single component to replace what would traditionally require multiple separate parts, thereby simplifying assembly while ensuring consistent performance across all functions.
2Loss of energy
If traditional separate components are used, then manufacturing is simpler, but thermal insulation is less effective
Solution Approach 1:
By combining the insulating block and sash frame seal into one integrated component, the patent achieves better thermal insulation performance while maintaining manufacturing efficiency. The integration ensures optimal positioning and contact between the insulating material and the sealing function, eliminating gaps that would occur with separate components, thereby reducing energy loss without significantly increasing manufacturing complexity.
Solution Approach 2:
The integrated component utilizes composite material construction, combining sealing material with insulating material in a unified structure. This allows the component to deliver both sealing and thermal insulation functions with enhanced effectiveness, while the integrated production process avoids the need for additional assembly operations that would increase manufacturing costs.
3Reliability
If the sash frame seal does not overlap the window frame member, then air gap sealing is insufficient, but device complexity increases
Solution Approach 1:
The integration of the insulating block into the sash frame seal creates a unified structure that naturally achieves the required overlap with the window frame member. The single integrated component is designed to extend and overlap the window frame member, ensuring consistent sealing contact and reliable tightness without requiring complex multi-component configurations or additional sealing elements.

AI summary
The invention relates to a roof window (1) with a frame (2) and a sash (4) which is movable relative to the frame (2) and carries a glazing (6). The glazing (6) is supported on a sash frame member (5) of the sash (4), on which a sash frame seal (12) is arranged to bridge an air gap (10) between the frame (2) and the sash (4). When the roof window (1) is closed, the sash frame seal, in cross-section, overlaps at least partially a frame frame member (3) of the frame (2). It is provided that an insulating block (18) arranged between the frame (2) and the sash (4), which engages in the air gap (10), is integrally formed with the sash frame seal (12) for thermal insulation of the roof window (1).
