Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft power systems face increased demands due to growing passenger power needs, leading to higher fuel consumption, and there is a desire for controllable electronic equipment operations to reduce energy consumption.
Innovation Solution
Implementing a system that allows passengers to select between standard and power-saving operating modes for electronic equipment, with the controller determining and displaying power usage differences, and adjusting equipment functionality accordingly, such as actuator speeds and lighting intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passengers use more electronic equipment and functions, then passenger satisfaction and convenience are improved, but power consumption and fuel burn increase
Solution Approach 1:
The system dynamically adjusts electronic equipment operation based on real-time power availability and aircraft phase of flight. The controller monitors power consumption of each equipment and automatically adjusts or shuts down devices when power thresholds are exceeded, enabling the system to adapt between full functionality and power-saving modes without manual intervention.
Solution Approach 2:
The system changes operational parameters of electronic equipment based on power availability. When power consumption exceeds available capacity, the controller modifies operation parameters such as shutting down non-essential devices, reducing power to climate control, or adjusting lighting levels to match available power capacity.
2Adaptability or versatility
If more electronic equipment is provided for passengers, then passenger enjoyment and comfort are improved, but aircraft power system demand increases
Solution Approach 1:
The system provides dynamic power management that enables full electronic equipment availability when power is sufficient, while automatically adjusting equipment operation when power demand exceeds capacity. The controller continuously monitors the balance between available power and equipment power consumption, dynamically enabling or disabling devices to maintain system stability.
Solution Approach 2:
The power management system segments electronic equipment into different priority groups and controls them independently. Essential safety equipment maintains full operation, while non-essential entertainment and comfort equipment is selectively adjusted or shut down based on power availability, allowing differentiated power allocation across equipment categories.
3Productivity
If high power modes are used for electronic equipment, then performance and functionality are improved, but fuel consumption increases
Solution Approach 1:
The system changes power consumption parameters of electronic equipment based on aircraft phase and power availability. During high-power phases such as takeoff and landing, non-essential equipment is shut down or operated at minimal levels. During cruise phases with excess power capacity, equipment can operate at full performance, optimizing the balance between productivity and energy loss.
Solution Approach 2:
The system converts the limitation of constrained power availability into a benefit by automatically optimizing equipment operation. The power management controller transforms the potential harm of power shortages into an opportunity for automated energy optimization, where equipment is intelligently adjusted to match available power capacity, thereby reducing unnecessary energy consumption and fuel burn.

AI summary
A system and method for operating electronic equipment (116) associated with a passenger seat and/or surrounding furniture in a vehicle cabin such as an aircraft cabin (100). According to a standard operating mode, electronic equipment (116) 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 (116) 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 (116) to perform differently during higher aircraft power demand periods as compared to lower aircraft power demand periods.
