Regulations
Business Context
Aircraft are designed with multiple redundant systems to ensure continued safe operation following equipment failures. Hydraulic circuits, electrical generation, flight control computers, navigation systems, communications equipment, and numerous additional systems incorporate redundancy to preserve safety under abnormal conditions. However, every additional component increases aircraft weight.
The Contradiction
Greater redundancy improves reliability, fault tolerance, and operational safety. However, additional redundant equipment increases aircraft weight, fuel consumption, maintenance requirements, lifecycle cost, and environmental impact. Reducing redundancy improves aircraft efficiency but decreases fault tolerance.
Why It Exists
Traditional engineering solutions frequently improve reliability by duplicating physical equipment. Although effective, this approach increases structural complexity and operational cost throughout the aircraft lifecycle.
Triz Perspective
Reliability should increasingly depend upon intelligent system architecture rather than physical duplication alone. AviationTRIZ encourages engineers to redesign redundancy using smarter technologies instead of simply adding hardware.
Solution Directions
Expected Benefits
Improved safety with lower aircraft weight, reduced fuel consumption, simplified maintenance, enhanced sustainability, and greater engineering efficiency.
