Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous data processing systems, especially in aeronautical networks, the complexity of configuring communication systems increases with the number of systems connected, requiring extensive adaptation and maintenance, as each system has a unique data format, making data exchange and system integration time-consuming and costly.
Innovation Solution
A method where a centralized memory stores all necessary information in a simple, homogeneous, and unique format, allowing all processing systems to access and understand data messages with a standardized configuration, minimizing data size and facilitating seamless communication across systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple heterogeneous processing systems are connected to a local network, then system functionality and data processing capability are improved, but communication configuration complexity and integration time increase
Solution Approach 1:
The patent implements a universal message format that can be used across all heterogeneous processing systems in the network. The standardized message structure with universal fields (message identifier, length, parameters) allows different systems with different data formats to communicate without requiring system-specific communication protocols, thereby reducing configuration complexity while maintaining system functionality.
Solution Approach 2:
The patent changes the parameter representation by storing communication configuration data (message formats, data structures, translation rules) as retrievable parameters in a centralized database rather than hardcoding them in each system. This allows the system to adapt to different communication scenarios by retrieving appropriate parameter configurations, reducing the complexity of integrating new systems.
2Ease of manufacture
If each processing system uses its own unique data format, then system-specific processing requirements are met, but data exchange between systems becomes time-consuming and costly
Solution Approach 1:
The patent introduces a centralized database as an intermediary that stores standardized message format definitions and translation rules. When data needs to be exchanged between systems with different formats, the receiving system retrieves the appropriate format definition from the database and uses it to interpret or translate the incoming data, eliminating the need for complex real-time format conversion and reducing data exchange time.
Solution Approach 2:
The patent performs preliminary action by pre-defining and storing all message format specifications, data structures, and translation rules in the centralized database before actual data exchange occurs. This allows systems to quickly retrieve and apply the correct format definitions during communication without performing complex format analysis in real-time, thereby reducing data exchange time while maintaining system-specific processing capabilities.
3Adaptability or versatility
If translation means are installed to enable data exchange between heterogeneous systems, then system interoperability is improved, but configuration and maintenance complexity increase
Solution Approach 1:
The patent merges all translation rules, message format definitions, and communication configuration data into a single centralized database that is accessible by all processing systems. This eliminates the need for separate translation modules in each system and consolidates configuration management in one location, significantly reducing configuration and maintenance complexity while maintaining full system interoperability.
Solution Approach 2:
The patent enables systems to self-configure by allowing them to autonomously retrieve message format definitions and translation rules from the centralized database based on the communication requirements. This self-service approach eliminates the need for manual configuration of translation means and reduces maintenance burden, as updates to communication protocols can be centrally updated in the database without requiring system-by-system reconfiguration.
4Productivity
If a new system is installed on the network, then network capability is expanded, but adaptation of existing translation means is required
Solution Approach 1:
The patent performs preliminary action by pre-storing all message format definitions, data structures, and translation rules in the centralized database before new systems are installed. When a new system joins the network, it can immediately retrieve the appropriate format definitions from the database and begin communicating without requiring time-consuming adaptation of translation means, thus expanding network capability quickly while minimizing integration time.
Solution Approach 2:
The patent implements a universal message format and centralized configuration database that can accommodate multiple different system types and data formats. This universal approach allows new systems to be integrated into the network without requiring custom translation adaptations, as the standardized format and centralized database automatically support the new system's communication requirements, thereby expanding network capability while reducing integration time.
