Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual wire routing evaluation methods are used, then design flexibility is maintained, but data accuracy and reliability deteriorate due to human error and inconsistency
Solution Approach 1:
The patent replaces manual mechanical evaluation methods with an automated computing system that retrieves wire routing data from an authoritative aircraft design database and performs electromagnetic disturbance analysis computationally. This substitution eliminates human error and inconsistency while maintaining design flexibility through programmable evaluation criteria.
Solution Approach 2:
The patent creates a virtual model of wire bundles by retrieving data from the aircraft design database, allowing the system to evaluate routing options without physically manipulating actual wires. This digital copying enables repeated evaluation of multiple routing scenarios without affecting the physical aircraft design.
2Measurement precision
If comprehensive electromagnetic disturbance analysis is performed on each wire bundle, then measurement precision improves, but computing resource consumption increases
Solution Approach 1:
The patent applies partial action by focusing electromagnetic disturbance analysis only on specific wire bundles that are candidates for routing, rather than analyzing all wires in the aircraft. The system selectively evaluates bundles based on their exposure to electromagnetic disturbances, performing comprehensive analysis only where necessary to meet design specifications.
Solution Approach 2:
The patent performs preliminary retrieval of wire bundle data from the authoritative aircraft design database before conducting electromagnetic disturbance analysis. This preliminary data gathering organizes information about wire positions, shielding, and routing paths, enabling more efficient computation during the actual electromagnetic effect estimation without redundant data processing.
3Adaptability or versatility
If wire routing is reevaluated during design changes, then design adaptability improves, but time consumption increases due to reevaluation requirements
Solution Approach 1:
The patent implements feedback by automatically detecting design changes in the aircraft design database and triggering reevaluation of affected wire bundles. The system monitors for changes in wire routing, shielding configurations, or electromagnetic disturbance sources, and only reevaluates bundles whose electromagnetic exposure may have changed, rather than performing full reanalysis of all wires.
Solution Approach 2:
The patent creates a dynamic wire routing evaluation system that adapts to design changes automatically. The system can be reexecuted at any stage during aircraft design, manufacturing, or post-production to account for changes in wire routing decisions, allowing the evaluation process to remain synchronized with the evolving aircraft design without manual intervention.
