Altitude Or Depth Control TRIZ Cases
- WIG Ground-Effect Elevation Control Using Distributed Surface Sensors
Distributed surface sensors and closed-loop control keep a WIG craft within ground effect over varying terrain, reducing drag and fuel use.
- UAV Altitude Control Using Surrounding Height Maps
A UAV sets its flight ceiling from nearby terrain and building heights, balancing take-off safety limits with access to elevated targets.
- Heave-Synchronized Landing Platform Assembly for Moving Sites
A processor times UAV landing to the downward heave phase and aligns platform angle with vehicle attitude to reduce damage at moving sites.
- Radio Triangulation Landing for GPS-Denied UAV Approach
Two-way ranging from ground radios lets a UAV triangulate position and land accurately without GPS or bulky ground radar.
- Autopilot Approach Mode Auto-Arming for Pilot Incapacitation
Timed monitoring and staged pilot alerts auto-arm autopilot approach mode when manual arming is missed during landing approach.
- Watercraft Landing Guidance Using Predicted Motion and Optical Signals
Predicted watercraft motion and optical navigation-light signaling guide aircraft approach routes to cut collision risk without aircraft modification.
- VTOL Landing Profile Control for Minimum-Jerk Touchdown
A minimum-jerk landing profile smooths VTOL descent and touchdown to limit tilt or drift after rotor slowdown, even in turbulence.
- UAV Landing Guidance Using GPS, Position Correction, and Light Signals
A three-phase UAV landing approach combines GPS, transponder-based position correction, and light signals for precise guidance in inaccessible zones.
- Climb-Optimized Takeoff System Pitch Attitude Control
A Climb-Optimized Takeoff System adjusts pitch attitude during air transition to maximize height gain.
- GNSS Landing Anomaly Detection via Inertial Deviation Comparison
A coast-skip reset trigger anomaly detector compares blended and raw GNSS deviations to identify data errors during approach.
