Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power systems for aircraft accessories are complex, leading to difficulties and time loss during installation and removal, especially during seat repitch or retrofit, due to intricate wiring and discrete connections.
Innovation Solution
A power system comprising a power module unit and detachable mounting rails that provide structural support and electrical power, with wireless control using standard or solid-state relays, allowing for easy installation and removal without the need for extensive wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional complex power delivery and discrete wiring systems are used, then electrical power can be delivered to accessories, but installation and removal become difficult and time-consuming
Solution Approach 1:
The power system is divided into separate functional modules: power delivery modules (PDMs) and power distribution units (PDUs). Each PDM contains integrated wiring and power delivery components that can be independently installed and removed from the aircraft structure, eliminating the need for complex discrete wiring connections during installation and removal operations
Solution Approach 2:
The power delivery modules are designed with standardized interfaces and mounting mechanisms that allow them to be universally installed in various locations within the aircraft cabin. The modules can serve multiple functions including power delivery, structural support, and integration with passenger service units, reducing the need for location-specific custom wiring
2Productivity
If conventional power systems with extensive wiring are used, then reliable power delivery is achieved, but installation time increases significantly
Solution Approach 1:
The wiring, power delivery components, and electrical connections are pre-assembled and integrated into the power delivery modules during manufacturing. This preliminary assembly eliminates the need for time-consuming on-site wiring and connection work during aircraft installation or modification operations
Solution Approach 2:
Multiple functions including power delivery, structural mounting, and electrical connections are merged into single integrated power delivery modules. This consolidation reduces the number of separate installation steps and components that need to be handled individually, significantly speeding up the installation process
3Ease of repair
If complex discrete wiring systems are used, then power can be delivered to multiple accessories, but the system becomes difficult to maintain and modify
Solution Approach 1:
The power distribution system is segmented into modular PDMs and PDUs that can be independently accessed, removed, and replaced. This segmentation allows maintenance personnel to service individual modules without having to work with or disconnect the entire wiring system, greatly simplifying repair and modification operations
Solution Approach 2:
The power delivery modules are designed with features that enable easy identification, removal, and replacement by maintenance personnel without requiring specialized tools or extensive technical knowledge. Standardized connectors and mounting mechanisms allow the modules to essentially self-install and self-configure when replaced

AI summary
A power system for an aircraft. The power system comprises a power module unit and at least one mounting rail detachably coupled to the power module unit. The mounting rail provides structural support and electrical power to the power module unit. A power system in one embodiment may use mounting rails that double as power rails supplying power to the power module unit. Control is accomplished over a wireless link. The power rail control may be accomplished remotely via a standard or solid state relay. Normal rail power for the rail mounted power module may come from the utility bus.
