Modular Wiring Configuration Matrix for Aircraft Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronics installation systems in aircraft and spacecraft are complex, heavy, and lack modularity and flexibility, requiring a long and iterative installation process due to customized wiring that is specific to each configuration.
Innovation Solution
A standardized electronics installation system with a connection matrix that allows for interchangeable wiring configuration modules, enabling the same mechanical structure to be used across different aircraft systems by routing data connections through pre-defined slots and configuration modules, which can be easily reconfigured without changing the underlying wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If customized wiring is used for each aircraft configuration, then specific equipment interconnectivity requirements are met, but installation complexity and time increase significantly
Solution Approach 1:
The wiring system is segmented into standardized connection points and modular wiring configurations. Each equipment type has predefined connection points, and wiring is divided into interchangeable modules that can be selectively assembled based on equipment layout, eliminating the need for completely custom wiring in each configuration.
Solution Approach 2:
Wiring configurations are prepared and tested in advance as standardized modules. Connection points are pre-defined for each equipment type, and wiring paths are predetermined, allowing rapid assembly during installation without complex on-site customization.
2Reliability
If separate copper wire based data networks are used for each electronic system, then system independence is maintained, but total weight increases
Solution Approach 1:
Multiple separate copper wire data networks are merged into a single standardized connection infrastructure. All electronic systems connect to the mechanical installation structure through unified connection points, eliminating redundant wiring while maintaining system independence through logical separation in the connection matrix.
Solution Approach 2:
Physical copper wire connections are replaced with a standardized mechanical connection system. The mechanical installation structure provides integrated electrical connections through predefined points, reducing the need for extensive copper wiring while maintaining reliable data transmission pathways.
3Ease of manufacture
If prior knowledge of equipment locations and interconnectivity is required, then wiring can be optimized for specific configurations, but installation process becomes long and iterative
Solution Approach 1:
All wiring configurations are predetermined and standardized in advance. Connection points are pre-defined for each equipment type, and wiring modules are prepared beforehand, eliminating the need for iterative on-site optimization and significantly reducing installation time.
Solution Approach 2:
The connection system is designed to be universal, accommodating multiple equipment types and configurations through standardized connection points. The same mechanical installation structure and connection matrix can serve various equipment arrangements without requiring custom wiring optimization for each case.
4Reliability
If complex customized wiring is installed in electronics bays, then specific system requirements are met, but modularity and flexibility for upgrades are reduced
Solution Approach 1:
The wiring system is segmented into modular, interchangeable components. Each equipment type connects through standardized points, and wiring configurations can be independently modified or upgraded without affecting the entire system, maintaining both functionality and flexibility.
Solution Approach 2:
The connection system is designed to be dynamic and reconfigurable. Equipment can be added, removed, or upgraded by simply changing the connection matrix configuration rather than rewiring the entire system, enabling easy adaptation to new requirements while maintaining reliable connections.
