Without Power Ampliication TRIZ Cases

Slat control system extends leading edge devices from sealed to gapped positions, reducing approach noise and aerodynamic drag during aircraft landing.

Movable disk couples and decouples actuator torque transmission via retaining part rupture to prevent seizure damage.

Integrated sensor units compare actuator outputs to detect skew conditions and malfunctions, reducing system weight while maintaining measurement precision.

A piston assembly with a pressure relief valve holds an aircraft wing trailing edge in neutral position under constant supply pressure.

Pivoted linkages in a spar assembly warp the wing, reducing actuator weight and stress penalties.

Lateral moving mechanism reduces wing thickness, lowering air resistance and drag.

Spring-loaded bistable mechanism deploys slats to spoil airflow and reduce wing loading when gust thresholds are exceeded, avoiding structural weight penalties.

Elastically deformable interconnection portions maintain slat pitch angle while accommodating skewing forces between tracks.

A selectively self-locking actuator uses a split nut and ball screw to reduce motor current during static holding.

Cross-axis flexure pivots create negative stiffness that counteracts centrifugal forces, reducing actuator weight and power requirements.

A detection device uses a deflector to skew the support frame, identifying actuator faults through mechanical displacement.

Segmented flaperon linkage uses fusable joints to shear under obstruction loads.

A hybrid gear arrangement uses a friction drive to transmit torque between axles without mechanical play.
