Fuselage Frames TRIZ Cases

Dividing the cross-member into upper and lower parts creates a dedicated channel for system passage, eliminating complex ground integration steps.

Expanding an outer skin segment with a longitudinal opening compensates for manufacturing tolerances between rigid fuselage sections.

Inverting junction placement to the outer skin surface preserves stringer continuity and structural stability without adding mass or creating aerodynamic drag.

Segmented floor elements transfer loads through mechanical connections to resolve the conflict between structural stability and customer-specific adaptability.

Replacing metallic butt-straps with laminar composite covers featuring joggle layers and clamps reduces drag and erosion while maintaining structural integrity.

Integrated side panels consolidate discrete reinforcements to reduce component count and weight while maintaining mechanical rigidity.

Temporary segmented braces maintain fuselage panel curvature during transport, reducing alignment complexity.

Composite stringers and frames integrate with inner and outer reinforcing elements to ensure continuous load transfer.

Machining recesses into the honeycomb core allows embedding space frame rods, achieving 45% weight reduction while maintaining structural integrity.

Toothing elements on a ductile insert absorb bolt stresses, preventing honeycomb core embrittlement and maintaining mechanical properties.

Polymer foam core sandwich composite meets aviation fire safety standards by embedding thin aluminum foil within fiber layers to reduce smoke density.
