Spars/Stringers TRIZ Cases

Battery inserts nested in aircraft structural cells store power while distributing loads, cutting weight and preserving stiffness.

Reference-hole positioning lets aircraft wing seals be applied before assembly, cutting interior access, damage risk, and assembly time.

Temporary C-shaped stiffeners or straps reinforce thin ribs and flanges during panel forming to prevent crippling without adding permanent weight.

An eccentric bush and threaded rail adjust airfoil components in orthogonal directions to correct misalignment, speed assembly, and meet tolerances.

Inclined asymmetric riblets cut surface friction while avoiding the fragility of ultra-thin plate-shaped riblets in practical use.

Common rib geometry and pultruded composite skins simplify wing assembly, cutting labor and build time while preserving structural integrity.

A Y-shaped composite coupler joins adjacent wing tubes and a central panel to raise joint strength while limiting weight and delamination.

A bridge-over connector links breather pipes to aircraft stringer ducts without intrusion, easing replacement while limiting pressure loss and electrostatic risk.

A Y-shaped woven composite coupler joins adjacent pressurized tubes and a central panel to raise joint strength while limiting weight and delamination.

A pull-rod deforms the plug and expels viscous sealant through orifices, enabling fast one-sided sealing of irregular cavities.

A pull-rod deforms a seal-filled envelope to plug narrow wing box cavities from one side without high injection pressure.
