Cosmonautic Vehicles TRIZ Cases
- Planetary Gear Angular Momentum Engine for Vehicle Resistance
A planetary gearbox and tungsten weight convert rotational centripetal force into linear force to overcome changing vehicle resistance.
- Projectile Gyroscope Compensation Using Image-Based Attitude Feedback
Image-derived rotation angles correct low-cost projectile gyroscope drift in real time, enabling accurate navigation without GPS.
- Gimbaled Spacecraft Thruster MPC Under Shared-Angle Constraints
A receding-horizon MPC coordinates coupled gimbaled thrusters for pose and momentum control while handling shared-angle limits and plume-safe placement.
- Separable Roller Screw Assembly for Low-Shock Spacecraft Release
A planetary roller screw release mechanism replaces pyrotechnic separation to cut shock, manage axial loads, and improve spacecraft release control.
- Elastic Locking Assembly for Precise Deployment Alignment
Elastic strips and a spring-loaded movable body capture and align deployed structural parts for precise, reliable locking in flexible assemblies.
- Additive Spacecraft Panel Structure With Truss Core and Integrated Features
A single-build panel with two skins and a printed truss core improves thermal management while reducing labor, assembly, and post-processing.
- Selective Data Compression for Bandwidth-Limited Satellite Transmission
Content-aware compression assigns appeal factors to data so satellites preserve critical information while reducing transmission load.
- Spacecraft Docking Ring With Regenerative Resistance Damping
Regenerative current in linear actuators adds passive resistance during contact, correcting spacecraft misalignment and damping inertia without complex control.
- Tethered Ion Blocker Layout to Prevent Ion Self-Impingement
A tethered ion blocker uses planetary magnetic-field curvature to intercept ions, boost thrust, and prevent spacecraft self-impingement.
- Ion Engine Frequency Generator Resonance Tracking Control
Waveform edge-offset feedback adjusts switch timing to keep an ion engine frequency generator at resonance during plasma ignition.
- Spacecraft Docking Ring With Regenerative Damping for Misalignment
Regenerative current in linear actuators creates passive resistance during contact, correcting spacecraft misalignment and damping inertia without complex control.
- Ion Engine Frequency Generator Control for Resonant Plasma Ignition
Voltage-current edge offset feedback adjusts switch-on timing to keep an ion engine frequency generator at resonance during plasma ignition.
- Tri-Axis Magnetoresistance Sensing With Flux Concentrator Bridge
A flux concentrator and fixed Wheatstone bridge enable compact tri-axis magnetic sensing with fewer structures and simpler manufacturing.
