Machines/Engines TRIZ Cases
- Flexible Coupling for Camshaft Phaser Torsional Connection
Arc-shaped flexible connectors accommodate radial and axial movement between camshaft phasers, resolving tolerance variability in concentric assemblies.
- Single Well Nuclear Density Gauge for High-Pressure Vessels
Nested source and transmission chambers install via one vessel nozzle, reducing radiation absorption by thick walls while preserving structural integrity.
- Wind Turbine Blade with Auxiliary Support and Reverse-Airfoil Drag Element
Auxiliary supports stabilize hybrid blades exploiting lift and drag forces, reducing turbulence and improving vertical axis turbine efficiency.
- Polymeric Structural Oil Pan with Cavity for Vibration Reduction
Composite polymeric oil pans replace heavy metal units, using layered materials and structural cavities to maintain rigidity while lowering weight and cost.
- Buoyancy-Driven Power System Using Rotor-Vessels
A buoyancy-driven power system uses rotor-vessels to convert mechanical energy into electrical current.
- High-Pressure Fuel Pump Filter Concave Edge Design
Concavely curved screen edges widen axial web sections to resist bending stress, maintaining throughput area while preventing inward folding.
- Humidity-Driven Rotary Engine Using Water-Responsive Materials
Water-responsive materials expand and contract to drive a rotary engine generating electricity from ambient humidity gradients.
- Gas Idling Transition Passage for Dual-Purpose Carburetor
Segmented parallel air inlet pipes ensure stable engine idling by resolving insufficient gas intake and suction vacuum issues.
- Integrated Drain Valve for Fluid Filter Servicing
A fluid filter incorporates a structural drain valve that must open before the cartridge removal.
- Generator Management System Fuel Tracking
An information processing apparatus aggregates fuel, position, and state data from generators to resolve information loss during disaster response.
- Illuminated Sight Glass with Recessed LED for Safe Fluid Inspection
A sight assembly integrates an internal light source within a body portion to illuminate fluid flow through an aperture.
- Cooling Duct Piston Inlet Angle Optimization
Shaping the cooling duct piston inner surface inlet angle to 85–95 degrees eliminates countersinking steps and reduces production costs.
- Air-intake duct with segmented coupling and guide members
Segmenting the air-intake duct into an elastic rubber coupling member and a lightweight air guide member reduces weight while maintaining air-tight sealing.
