Fuselage Frames TRIZ Cases
- Aircraft Fairing Fixing Device with Integrated Electrical Contacts
Combines translational fixing and elastic contacts to eliminate separate plug connections in difficult-to-access areas.
- Composite Spar Outward Flanges Assembly
Outward-facing flanges allow external skin attachment, eliminating interior access needs and reducing assembly complexity.
- Aircraft Composite Lamination Using Flat and Wavy Prepreg Portions
Flat and wavy prepreg portions transform into bent sections via forming die pressure, eliminating complex auxiliary yarns to lower production costs.
- Aircraft Interior Component Suspended Mounting System
Suspended mounting mechanism with structure and component holders creates a rear gap for aircraft interior components.
- Aircraft Panel Liquid Diversion via Surface Energy
Surface treatment forms liquid flow paths on aircraft panels to divert moisture, eliminating heavy separate devices that lose effectiveness under compression.
- UAV Energy Dispersion Plug for Crash Safety
A wedge-shaped plug shatters hollow UAV structural members upon impact to disperse kinetic energy.
- High-Wing Aircraft Fuselage Load Transfer via Through-Fuselage Columns
Through-fuselage columns transfer wing downward loads to the main landing gear, resolving the contradiction between structural strength and aircraft weight.
- Y-Shaped Composite Stringer for Aircraft Panel Buckling
An asymmetric Y-shaped composite stringer resolves buckling resistance and torsional behavior trade-offs by maximizing moment of inertia per unit weight.
- Flexible Composite Packer for Aircraft OML Tolerance
A flexible carbon fibre composite packer conforms to airframe surfaces to define a precise inner mould line, resolving Outer Mould Line tolerance challenges.
- Particulate Prepreg Forming Aid for Composite Wrinkle Control
A particulate forming aid deposits spatially varying shear and tack on prepreg plies to enable controlled interlaminar slippage during composite draping.
- Composite Tail Boom Stiffening Framework
Rod and ring stiffeners between skins eliminate adhesives, resolving weight and production complexity trade-offs.
- Bidirectional Electronic Unit Module Insertion
A bidirectional electronic unit compartment enables symmetric module insertion via parallel connection faces and magnetic couplers.
- Aircraft Integration Module for Equipment Assembly
An integration module attaches aircraft equipment and lines outside the fuselage before insertion into the technical bay.
- Gap Filler Roller Assembly for Variable Curvature Composite Fabrication
Rotatable support members adjust roller axes to form variable curvature gap fillers, eliminating abrupt surface changes in aircraft stringer applications.
- Hat Stringer Recess Design for Composite Void Reduction
A hat-shaped stringer incorporates a recessed cap portion to position internal composite walls that reinforce the structure.
- Composite Joint Transverse Flaps Load Continuity
Transverse flaps join intersecting structural members to transmit loads, eliminating extra parts that increase weight and complexity.
- Mandrel Package Manufacturing Apparatus for Composite Stringers
A mandrel package manufacturing apparatus consolidates composite layups using vacuum pressure and radius fillers.
- UAV Frame Assembly with Segmented Circuit Board Access
Segmenting the housing into distinct chambers allows independent maintenance of stacked circuit boards while improving heat dissipation.
- Composite Helicopter Tail Boom Attachment Ring
A composite attachment ring segment connects a helicopter tail boom to the fuselage via longitudinal tension members distributed around its perimeter.
- Contoured Composite Hat Stringer Cap Wrinkling Reduction
An inflatable bladder constrains the cap of a contoured composite hat stringer during forming, eliminating buckling and wrinkling defects.
- Cellular Core with Vertical Stiffeners for Low Frequency Noise Attenuation
Vertical stiffeners in a cellular core maintain structural integrity while resonating chambers attenuate low frequency noise without increasing panel thickness.
