Distributed Graphics Processing for Incremental HMI Certification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On-board human-machine interface systems for aircraft face challenges with obsolete components requiring frequent re-certification due to changes, leading to time-consuming and costly modifications, and varying industry standards necessitate reconfiguration and additional certifications.
Innovation Solution
A graphic data processing system with distributed formatting means across multiple cores, allowing partial or full partitioning, enabling incremental certification and modular updates without affecting the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If components are grouped into a single physical core to simplify system architecture, then device complexity is reduced, but any component update requires re-certification of the entire system
Solution Approach 1:
The patent divides the processing chain into separate logical processing units that can be distributed across multiple physical cores. Each processing unit (graphics processing, display processing, audio processing, etc.) can be independently updated and certified without affecting other units, thus resolving the contradiction between simplified architecture and update flexibility.
2Adaptability or versatility
If components are distributed across multiple cores to enable independent updates, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal processing architecture where multiple processing units can operate across different cores with standardized interfaces and communication protocols. This multi-functional design allows the same processing units to be distributed across various core configurations without increasing complexity, as the universal interface layer abstracts the distribution complexity.
3Ease of manufacture
If commercial off-the-shelf components are used to reduce manufacturing costs, then ease of manufacture is improved, but system determinism and control are worsened
Solution Approach 1:
The patent segments the processing chain into independent logical units that can be implemented using COTS components. Each segment can be individually validated and certified, allowing the use of cost-effective commercial components while maintaining overall system determinism through modular validation of each segment's behavior.
4Adaptability or versatility
If the processing chain is reconfigured to meet different industry standards, then adaptability is improved, but re-certification requirements increase time and cost
Solution Approach 1:
The patent implements a dynamic processing chain where processing units can be selectively activated or deactivated based on the required industry standard. The system can adapt its configuration to meet different standards (aerospace, automotive, medical) by enabling specific processing units while keeping others inactive, avoiding the need for physical reconfiguration and extensive re-certification.
