Parachutes TRIZ Cases
- Off-Center Parachute Flight Termination With Redundant Burn-Wire Latches
Redundant burn-wire latches separate the UAV door, while an off-center parachute induces torque for predictable spiral descent.
- Parachute Drogue Delay Mechanism for Wake-Turbulence Avoidance
This case uses a 0.5–2 second mechanical delay between drogue and main parachutes to reduce wake-turbulence collision risk.
- Circuit Anomaly Diagnosis Using Voltage Thresholds for Igniter Circuits
This case uses amplified voltage readings and known resistors to classify normal, shorted, or disconnected igniter circuits.
- Spring-Loaded Load Disconnect With Multidirectional Force Guides
Guides redirect trigger force to spring-loaded carabiners, enabling reliable release despite payload mass and orientation.
- Parachute Canopy Segmentation for Rapid Deployment and Shape Stability
Varied air permeability across parachute panels speeds inflation while outer panels maintain shape and reduce altitude loss.
- Modular Air Delivery Barrel With Shock-Absorbing Payload Protection
A stretchable strap and nested barrels cushion impact loads while modular parts speed setup and replacement after delivery.
- Near-Space Payload Recovery Using Pre-Deployed Anti-Tangle Parachutes
A lighter-than-air launch system uses pre-deployed, separated parachutes to support reliable recovery above 70,000 feet.
- UAV Payload Coupling Slot for Hover-Based Delivery
This UAV coupling slot replaces moving parts with passive geometry for hover-based delivery and retrieval while limiting re-engagement risk.
- Unmanned Fixed-Wing VTOL Aircraft With Six-Unit Thrust Redundancy
This case uses tilting rotors, segmented control surfaces, and parachute deployment to preserve flight stability during failures.
