Cosmonautic Vehicles TRIZ Cases
- Flexible Propellant Tank Membrane for Safe Space Metering
A multilayer inflatable membrane separates and meters propellant in space while reducing leak risk and material compatibility issues.
- Androgynous Coupling with Radial Locking for Low-Force Alignment
Radial locking contours and blocking elements align coupling partners and secure form-fit engagement with lower coupling and decoupling force.
- Heaterless Insertless Hollow Cathode for Fast Low-Power Electron Emission
Direct electrical discharge replaces resistive heating in a hollow cathode, cutting startup time and power demand for small-satellite thrusters.
- Space Solar Cell String Protection Layout for Replaceable Diodes
Separate front-side covers and metal-strip connections make string protection diodes easier to replace while reducing back-side wiring and heat buildup.
- Magnetic Tank Support Assembly for Cryogenic Heat Isolation
Repulsive tank and structure magnets suspend a cryogenic vehicle tank without struts, cutting heat conduction and boil-off.
- Wire Weave Manufacturing with Looping Crossing Wire Control
Controlled looping of a crossing wire around longitudinal wires enables thin-weave production with low strain, stable joints, and space-ready integrity.
- Collecting Electrode Geometry for Temperature-Resistant Photoelectric Elements
By constraining collecting electrode dimensions, this case reduces thermal-stress peeling and preserves photoelectric function through temperature cycles.
- Heaterless Dispenser Cathode Ignition Circuit for Satellite Propulsion
A high-voltage ignitor and sustaining circuit starts electron discharge without cathode heaters, cutting weight and improving satellite propulsion reliability.
- Ferrofluid Attitude Control Without Reaction Wheels or Fuel
Rotating magnetic fields drive ferrofluid in a closed loop to generate reversible angular momentum for precise spacecraft attitude control without wheels or fuel.
