Electric Power Distribution TRIZ Cases
- Non-Rotary-Wing Aircraft Propulsion System with Direct AC Wingtip Drive
Segmented power circuits eliminate conversion losses during cruising and enable emission-free take-off by switching to battery storage.
- Split Tubular Bulkhead Seal Fitting for Tool-Free Wiring Installation
Separable multi-piece components allow tool-free installation of existing wiring, reducing connection time by four minutes per fitting.
- DC Overvoltage Protection with Independent Relay Power
Independent relay power ensures protection reliability when monitored AC or DC busses fail, preventing equipment damage.
- Virtual Channel Abstraction Layer for Aircraft Power Control
Virtual channels aggregate control signals to reduce system complexity and communication latency in aircraft electrical power systems.
- Under Floor Wiring Trough for Aircraft Cabin Flatness
Wiring troughs route cables below the floor panel to eliminate raised raceways that obstruct galley carts and create uneven walking surfaces.
- Propulsor Management for Electric Aircraft Drag Reduction
A flight controller detects hover to fixed-wing transitions and moves propulsors to minimize drag, reducing air resistance.
- Capacitive Discharge Bonding Integrity Monitor
Aircraft electronics use capacitive discharge to measure bonding integrity via voltage differentials across chassis interfaces.
- Guard Wire Shielding for Aircraft Power Feeder Reliability
Segmented shielding reduces weight and heat buildup while protecting aircraft electrical systems from lightning strikes.
- Parallel Hybrid Propulsion System Engine Wear Reduction
A parallel hybrid propulsion system supplements gas turbine power with an electrical motor during take-off and climb phases.
- Aircraft Power and Propulsion System with Dual Spool Segmentation
Dual spool segmentation distributes mechanical extraction across four DC channels, maintaining engine surge margin while supporting heavy electrical loads.
- Dual-Function Aircraft Power Switching
An aircraft routes power from a turboshaft generator to either flight motors or an external outlet, delivering electricity to remote disaster zones.
- Turbine Engine Rapid Reactivation via Hybrid Power Storage
Series-connected energy storage elements deliver high voltage to electric machines, resolving insufficient starting torque in conventional 28V systems.
- Aircraft Towing Power Architecture for Electric Brake Systems
Segmenting power circuits isolates nonessential loads, extending backup battery duration while maintaining brake reliability.
