Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft electronic equipment power consumption poses a challenge as it increases demand on the vehicle power system, leading to higher fuel burn during higher power demand periods.
Innovation Solution
A system for selectable power mode operation of electronic equipment in an aircraft passenger cabin, featuring a controller and interface unit that allow passengers to switch between standard and power-saving modes, optimizing power usage based on aircraft power demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic equipment operates in standard operating mode, then passenger comfort and functionality are maintained, but power consumption increases leading to higher fuel burn
Solution Approach 1:
The system dynamically adjusts the operating mode of electronic equipment based on real-time aircraft power demand conditions. The controller monitors power demand periods and automatically switches between standard and power-saving modes, making the system adaptive rather than static. This resolves the contradiction by allowing full functionality when power is abundant while reducing power consumption when demand is high.
Solution Approach 2:
The system changes operational parameters by switching between two distinct operating modes: standard mode with full functionality and power-saving mode with reduced performance. This parameter change approach allows the system to optimize the balance between passenger comfort and power consumption based on external conditions (aircraft power demand), resolving the technical contradiction.
2Loss of energy
If electronic equipment operates in power saving mode during higher aircraft power demand periods, then fuel consumption is reduced, but passenger comfort and functionality are degraded
Solution Approach 1:
The system implements periodic monitoring of aircraft power demand and adjusts operating modes accordingly. During higher power demand periods, it switches to power-saving mode to reduce fuel consumption, while during lower demand periods, it returns to standard mode to restore full functionality. This periodic adaptation resolves the contradiction by temporarily accepting reduced comfort to achieve energy savings when necessary.
Solution Approach 2:
The system dynamically responds to changing power demand conditions by adjusting its operational state. Rather than maintaining a fixed mode, it continuously adapts between standard and power-saving modes based on real-time conditions, allowing it to minimize fuel loss while managing passenger comfort expectations during high-demand periods.
3Adaptability or versatility
If passengers have full control over electronic equipment power modes, then individual preferences are satisfied, but system complexity increases
Solution Approach 1:
The system provides self-service by automatically monitoring aircraft power demand and selecting appropriate operating modes without requiring continuous passenger intervention. The controller autonomously makes decisions based on power demand conditions, reducing the complexity of manual control interfaces while still allowing passengers to access control options when desired.
Solution Approach 2:
The control system dynamically adjusts its level of automation based on conditions. While the system can operate autonomously to simplify the interface, it maintains passenger accessibility to mode selection, creating a flexible control architecture that balances simplicity with adaptability without significantly increasing overall system complexity.

AI summary
A system and method for operating electronic equipment associated with a passenger seat and/or surrounding furniture in a vehicle cabin such as an aircraft cabin. According to a standard operating mode, electronic equipment is activated and/or operable without power consumption restrictions. According to a power saving operating mode, corresponding to an economy mode or a Sabbath mode, electronic equipment is inactivated and/or operable with power consumption restrictions. Operating mode selection may be via an interface unit associated with the passenger seat. In embodiments, power consumption statistics are calculated and displayed to the passenger to indicate an economy score for a flight. In embodiments, selecting power saving mode may cause the electronic equipment to perform differently during higher aircraft power demand periods as compared to lower aircraft power demand periods.
