Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power communication architecture for aircraft is complex, requiring each power electronic module to host its own control laws and sensors, leading to increased development and integration challenges, and lacks efficient monitoring of unassigned loads, resulting in potential safety issues and inefficiencies.
Innovation Solution
A power communication architecture where the power electronic module management unit (PEMMU) centralizes control laws and integrates current loops, simplifying control and communication by standardizing interfaces and eliminating parallelization buses, while enabling permanent monitoring of loads through a single component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each power electronic module hosts its own control laws and sensors, then the system achieves distributed control and redundancy, but the device complexity and development integration challenges increase significantly
Solution Approach 1:
The patent introduces a central control unit as an intermediary that manages control laws and coordinates multiple power electronic modules. This mediator handles the complexity of distributed control by centralizing the control law storage and distribution, allowing modules to operate in parallel while maintaining system-wide coordination without each module needing independent control capabilities
Solution Approach 2:
The patent merges the control law functionality from individual power electronic modules into a single centralized control unit. This consolidation reduces device complexity by eliminating redundant control law storage across multiple modules while maintaining the benefits of distributed power electronic operation through centralized intelligence
2Adaptability or versatility
If multiple power electronic modules operate in parallel on the same load, then the system achieves load sharing and redundancy, but communication requirements and integration challenges increase
Solution Approach 1:
The centralized control unit serves multiple functions simultaneously: it stores control laws, manages parallel module coordination, handles load sharing calculations, and provides system-wide monitoring. This multi-functional approach eliminates the need for complex peer-to-peer communication between modules while achieving load sharing and redundancy
3Extent of automation
If power electronic modules require more intelligence for autonomous operation, then the system achieves better autonomous control, but development and integration challenges increase
Solution Approach 1:
The patent extracts the intelligence and control law processing requirements from individual power electronic modules and places them in a dedicated centralized control unit. This separation allows the power electronic modules to be manufactured and tested independently with simpler functionality, while the centralized unit handles all complex control logic and autonomous decision-making
