Arrester Hooks TRIZ Cases

A contracting suction cup and distributed contact points let small aerial vehicles dock stably on unprepared surfaces with high attachment stiffness.

A tethered parent-child UAV uses tension feedback, rail support, and wing-angle control to prevent crashes and keep delivery flight stable.

A rail-hung connector and wire-lift mechanism let a UAV switch rails, lower packages precisely, and reduce crash risk during urban delivery.

Flexible shafted adhesive elements conform to complex surfaces while maintaining adhesion and reducing residue or sheet breakage during peeling.

A contracting suction cup and surrounding contact points let small aerial vehicles dock securely on unprepared surfaces with higher stiffness.

A rail connector, motor speed control, and body tilt adjustment help a delivery UAV prevent crashes and stay stable during anomalies.

A rail connector and movable block let a delivery UAV run at lower rotor speed while maintaining guided motion, crash protection, and precise delivery.

Deployable augers or arcuate anchors hold a lightweight UAV on soil or a landing pad, preventing lift-off during agricultural data capture.

Suspension cables and a receiving latch enable fixed-wing UAV take-off and recovery on moving vehicles despite wind, turbulence, and deck obstacles.

In-board wing hooks couple to a recovery cable near the wing root, enabling runway-free UAV landing with lower weight and less structural stress.

A drogue canopy controller adjusts the surface area of an inflatable drogue to match varying airspeeds.

A capture device uses a resilient landing depression to absorb kinetic energy from unmanned aerial vehicles during arrest.

Inflatable ballutes expand a kill vehicle cross section to increase collision probability, reducing navigation precision requirements and system complexity.

Segmented pins measure soil resistance and depth to resolve measurement precision versus device complexity.

An inflatable airbag system uses selective vent valves to manage gas flow during impact and re-inflate for post-crash flotation.

Internal pneumatic rotors steer projectiles by expelling air radially, eliminating drag from external control surfaces.

Pivot assembly decouples vertical damper actuator from trapeze deployment mechanism.

An integrated rotor hook captures a recovery line during flight, eliminating heavy landing gear and reducing system weight while ensuring safe deceleration.

Carrier aircraft deploys a capture line to retrieve unmanned aerial vehicles, eliminating the need for ground runways in constrained environments.

Pivoting pole pairs and tear straps absorb impact energy, protecting lightweight aircraft structures from damage during mobile recovery operations.
