Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical cable/wire connectors and mechanical interconnects are used to transfer power and data between modular components, then power and data transfer can be achieved, but the connectors are susceptible to corrosion, damage, dust, debris, moisture, and other environmental factors that deteriorate performance
Solution Approach 1:
The patent replaces mechanical electrical connectors with inductive coupling between coils. Power and data are transferred wirelessly through electromagnetic induction, eliminating physical contact points that are vulnerable to environmental factors. The first coil on the fuselage and second coil on the wing module enable inductive power transfer without exposed connectors.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium for power and data transfer. Instead of direct electrical contact through connectors, the system uses magnetic coupling between coils to transfer energy and information, providing isolation from environmental contaminants while maintaining functional connectivity.
2Adaptability or versatility
If modular components are designed with swapable parts like wings, then adaptability and maintenance ease are improved, but the connection interfaces between modules become exposed to environmental damage
Solution Approach 1:
The patent replaces mechanical electrical connectors at modular interfaces with inductive coupling. The coils are embedded or conformally coated on the module surfaces, allowing frequent attachment and detachment of modular components like wings without degrading connection reliability, as there are no exposed electrical contacts to corrode or damage.
Solution Approach 2:
The patent uses conformal coatings to apply coil structures onto the surfaces of modular components. This thin-film approach allows the coils to conform to the module geometry while remaining protected within or on the surface, maintaining adaptability for modular assembly while protecting the electromagnetic interface from environmental exposure.

AI summary
An aircraft includes a first structure that includes a first surface and a first coil conformed to, or embedded within, the first surface. The aircraft includes a second structure that includes a second surface and a second coil conformed to, or embedded within, the second surface. The second structure is configured to couple to the first structure such that the first coil is aligned with the second coil to enable inductive coupling between the first coil and the second coil.
