Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission is implemented using data bus (ARINC 429 or 664 bus), then device interconnection is achieved, but transmission rate is low and cable weight increases
Solution Approach 1:
The patent replaces the mechanical cable-based data bus system with a wireless communication system. Each airborne device is equipped with a wireless communication module that can transmit and receive data packets wirelessly, eliminating the need for physical cable connections between devices while maintaining data transmission functionality.
Solution Approach 2:
The patent extracts the data transmission function from the cable-based bus system and implements it independently through wireless communication modules integrated into each airborne device. This allows devices to communicate without being physically connected through heavy cables.
2Adaptability or versatility
If numerous airborne devices are interconnected using data bus, then device connectivity is achieved, but the number and weight of aircraft cables increase significantly
Solution Approach 1:
The patent implements a universal wireless communication interface that can be integrated into any airborne device regardless of its specific function. This universal interface enables any device to communicate with any other device wirelessly, providing flexible interconnection without requiring dedicated cables for each device pair.
Solution Approach 2:
The patent replaces the cable-based mechanical connection system with a wireless electromagnetic field-based communication system, eliminating the need for physical cable infrastructure while maintaining full device interconnection capability.
3Reliability
If shielded cables are used for data transmission, then signal quality is maintained, but desoldering occurs over time reducing transmission quality
Solution Approach 1:
The patent replaces the cable-based transmission medium with wireless electromagnetic wave transmission, eliminating the physical cable that is subject to desoldering and connection degradation over time. This improves long-term reliability by removing the vulnerable mechanical connection points.
Solution Approach 2:
The patent extracts the data transmission function from the cable medium entirely, implementing it through wireless communication modules that transmit data through electromagnetic fields rather than physical conductors, thereby eliminating the cable service life limitation.
4Weight of stationary object
If wireless transmission apparatus is integrated into airborne devices, then cable quantity is reduced, but device structure complexity increases
Solution Approach 1:
The patent merges the wireless communication module directly into the airborne device structure, combining multiple functions (wireless transmission, reception, and processing) into an integrated unit that works seamlessly with the device's existing bus interface without adding external complexity.
