Aircraft Communication System Parallel Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft communication systems are inadequate for transmitting data quickly, as they rely on a single communication device or system, which can be slow and inadequate in emergency situations.
Innovation Solution
The system divides data streams into packets and transmits them simultaneously through multiple available communication devices or systems, using a data processing interface and routers to manage protocols and allocate packets based on availability and data rate, ensuring rapid transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a single communication device or system is selected for data transmission, then the system complexity is reduced and ease of operation is improved, but the transmission speed and productivity are insufficient for urgent messages
Solution Approach 1:
The patent segments the data stream into multiple data packets that can be transmitted simultaneously through different communication devices. This segmentation allows parallel transmission across multiple channels (e.g., SATCOM, HF, VHF), thereby increasing overall transmission speed while managing complexity through structured packetization and routing
Solution Approach 2:
The patent merges multiple communication devices and systems into a unified transmission architecture where data packets are distributed across different communication channels simultaneously. This combining of multiple devices operates in parallel to achieve higher aggregate throughput, resolving the contradiction between speed and complexity by leveraging multiple pathways
2Productivity
If the highest data rate communication device is selected exclusively, then transmission speed is maximized, but reliability and adaptability are reduced due to single-point failure risks and protocol limitations
Solution Approach 1:
The patent combines multiple communication devices with different data rates and protocols into a unified transmission system. By distributing data packets across multiple devices simultaneously, the system achieves higher aggregate throughput while maintaining reliability through redundancy - if one device fails, other devices can continue transmission
Solution Approach 2:
The system dynamically adjusts transmission parameters by selecting different communication devices based on real-time conditions such as data rate, availability, and protocol requirements. This parameter flexibility allows the system to optimize both speed and reliability by adapting to changing operational conditions
3Loss of time
If data is transmitted through multiple communication devices simultaneously, then transmission time is minimized and productivity is improved, but device complexity and difficulty of detecting and measuring transmission status increase
Solution Approach 1:
By segmenting data into packets with identification markers, the system enables parallel transmission across multiple devices while simplifying status monitoring. Each packet's structure includes metadata that facilitates tracking and accounting, making it easier to detect transmission status despite the increased number of active devices
Solution Approach 2:
The patent incorporates feedback mechanisms where the system monitors transmission status across multiple devices and adjusts packet routing accordingly. This feedback loop simplifies the measurement of transmission status by providing structured information about packet delivery, allowing the system to manage complexity through intelligent control
