Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication systems are used in aircraft, then data transmission reliability is maintained, but system flexibility and scalability are reduced while maintenance complexity increases
Solution Approach 1:
The patent replaces wired mechanical communication systems with wireless communication systems. The wireless avionics communication network eliminates physical cable connections while maintaining data transmission reliability through protocol layers, error correction mechanisms, and redundant communication paths, thereby improving system flexibility and scalability.
Solution Approach 2:
The patent introduces communication protocol layers and network management entities as intermediaries between wireless communication components. These intermediaries ensure reliable data transmission by handling error correction, data prioritization, and network coordination, compensating for the lack of physical connection stability inherent in wireless systems.
2Stability of the object's composition
If wired communication systems are used in aircraft, then data transmission stability is maintained, but maintenance costs and complexity increase due to excessive cables
Solution Approach 1:
The patent extracts and eliminates the physical cable infrastructure from the avionics communication system. By removing excessive cables and wired connections, the system reduces maintenance complexity and costs while maintaining data transmission stability through wireless communication protocols and network management mechanisms.
Solution Approach 2:
The patent substitutes mechanical wired connections with wireless communication systems. This replacement eliminates the need for physical cable maintenance, connection inspections, and hardware repairs, thereby reducing maintenance complexity while maintaining transmission stability through software-based error correction and protocol management.
3Adaptability or versatility
If wireless communication is implemented in aircraft, then system flexibility and scalability are improved, but data loss and reliability concerns arise
Solution Approach 1:
The patent implements error correction codes, data redundancy mechanisms, and buffer memory systems as beforehand cushioning measures. These pre-configured protective mechanisms compensate for potential wireless communication failures, data corruption, or packet loss, ensuring reliable data transmission while maintaining system flexibility and scalability.
Solution Approach 2:
The patent incorporates feedback mechanisms including acknowledgment protocols, error detection and correction systems, and network status monitoring. These feedback loops enable the wireless avionics network to detect and correct transmission errors, request retransmission of lost data, and adapt to changing communication conditions, thereby maintaining reliability while preserving system flexibility.
4Object-affected harmful factors
If wired communication systems are used in aircraft, then security against unauthorized access is maintained through physical connectivity control, but scalability and deployment flexibility are reduced
Solution Approach 1:
The patent replaces physical connectivity-based security with software-based security mechanisms including encryption, authentication protocols, and access control lists. These electronic security measures protect wireless communications from unauthorized access while allowing flexible system deployment and reconfiguration without physical cable changes.
