Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial aircraft, retrofitting additional electrical loads in passenger supply modules is complex and costly, requiring modifications to the power supply bus or individual modules, as there is no provision for reserve power transmission.
Innovation Solution
A functional enhancement module that includes a controller and power controller to detect and manage the current power flow, ensuring that the combined power take-up of the module and enhancement module does not exceed the power specification, allowing for the integration of additional electrical loads without altering the existing power supply bus or modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional electrical loads are retrofitted in passenger supply modules, then the functionality and power capacity of the module is improved, but the complexity and cost of the power supply system increases due to required modifications
Solution Approach 1:
A power controller is introduced as an intermediary device between the power supply bus and the functional module. This controller monitors the power flow and regulates the power consumption of the functional module and its enhancement, enabling additional electrical loads to be integrated without modifying the existing power supply bus infrastructure.
Solution Approach 2:
The system implements a feedback mechanism where the controller continuously detects the current power flow from the power supply bus and uses this information to dynamically control the power consumption of the functional module. This ensures that the combined power demand never exceeds the bus capacity, allowing versatile power usage without system modifications.
2Power
If the power supply bus is reinforced to transmit additional electric power, then the power transmission capacity is improved, but the manufacturing cost and system complexity increases
Solution Approach 1:
Instead of changing the physical parameters of the power supply bus (such as conductor size or material), the system changes the operational parameters by introducing intelligent control. The power controller dynamically adjusts the power consumption of the functional module based on the detected power flow, effectively increasing the usable power capacity without any physical modifications to the bus.
3Adaptability or versatility
If individual passenger modules are overhauled or replaced to reduce maximum power take-up, then the compatibility with existing power supply bus is improved, but the manufacturing cost and complexity increases
Solution Approach 1:
The system transitions from a static power consumption model to a dynamic one. The power controller continuously adjusts the power consumption of the functional module based on real-time detection of the power supply bus status. This dynamic control enables the module to adapt its power usage to available capacity, achieving compatibility with existing buses without costly overhauls or replacements.

AI summary
A functional enhancement module is for vehicles and for enhancing a functional module which is supplied with electric power via a power supply bus. The functional enhancement module is configured to be supplied with the electric power via the power supply bus. The functional enhancement module includes: a controller having a power specification for a maximum power flow of the functional module and being configured to detect a current power flow at a reference point; and a power controller configured to control a power take-up of the functional enhancement module. The controller is configured to control the power controller in accordance with the detected power flow, such that a combined power take-up of the functional module and the functional enhancement module does not exceed the power specification.
