Modular Power Distribution Assembly for Aircraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power distribution nodes in electrical power systems, such as those in aircraft, are not optimized for minimal installation volume, leading to larger-than-necessary rack assemblies with unused or underutilized components.
Innovation Solution
A modular power distribution assembly comprising a first power module with a power input and bus bar connector, and a set of second power modules with power switches and bus bar connectors, which are physically secured to align and receive a continuous bus bar, along with end modules equipped with communication interfaces, power supplies, and switching modules for efficient power distribution and conversion.

Engineering Contradiction Analysis
1Volume of moving object
If conventional rack assemblies are used for power distribution nodes, then power conversion and switching functions can be provided, but the installation volume is larger than necessary and components are unused or underutilized
Solution Approach 1:
The power distribution system is divided into modular power modules that can be independently configured. Each module contains specific power conversion or switching functions, allowing the system to be assembled with only the necessary components for each application, thereby reducing installation volume while maintaining required functionality.
Solution Approach 2:
The power modules are designed with universal interfaces and standardized configurations that allow them to perform multiple functions. A single module type can be used in different positions and configurations to provide various power conversion and switching operations, eliminating the need for dedicated components for each function and reducing overall system volume.
2Adaptability or versatility
If larger rack assemblies are used to ensure all power distribution functions are available, then versatility is improved, but weight increases
Solution Approach 1:
By segmenting the power distribution system into functional modules, only the required modules are installed in each rack position. This eliminates the weight of unused components that would be present in a conventional full-featured rack assembly, while still providing all necessary power distribution functions through selective module placement.
Solution Approach 2:
The system allows dynamic configuration of power distribution capabilities by selecting and arranging different module types in different rack positions. This enables the weight and functionality parameters to be optimized for each specific application rather than being fixed by a standardized large rack design.
3Reliability
If more components are included in power distribution nodes to ensure reliability, then reliability is improved, but device complexity increases
Solution Approach 1:
Multiple power distribution functions (conversion, switching, protection) are merged into integrated power modules. Each module combines several functions that would traditionally require separate components, thereby maintaining reliability through functional redundancy while reducing the overall number of discrete components and simplifying the system architecture.
