Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infotainment unit (IVI) testing lacks sophisticated test platforms and best-fit test designs, leading to issues and defects being discovered only in live vehicle scenarios, resulting in brand reputation damage and production delays, with low defect counts and inadequate testing of functional components under cross-domain and peak load conditions.
Innovation Solution
A stability testing framework comprising a cross-domain and stress testing platform to simulate interactions and maximum load scenarios, generating reports on IVI unit stability, including a system with a processor to execute test cases and update frameworks based on defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If conventional testing methods are used, then testing simplicity is maintained, but defect detection capability deteriorates
Solution Approach 1:
The testing system is divided into three distinct testing platforms: cross-domain testing platform, stress testing platform, and aging testing platform. Each platform focuses on specific testing scenarios and functional components, allowing systematic defect detection while managing overall system complexity through modular organization.
Solution Approach 2:
The system performs comprehensive stability testing before the infotainment unit is deployed to production. By conducting cross-domain, stress, and aging tests in advance, potential defects are identified and resolved prior to launch, preventing defects from reaching production while maintaining a controlled testing process.
2Reliability
If comprehensive stability testing is implemented, then reliability improves, but testing time increases
Solution Approach 1:
The comprehensive stability testing is segmented into three parallel testing platforms that can operate simultaneously: cross-domain testing platform for interaction between functional components, stress testing platform for maximum load capacity testing, and aging testing platform for long-duration reliability testing. This segmentation enables parallel execution of multiple test types, reducing total testing time while maintaining comprehensive coverage.
Solution Approach 2:
The aging testing platform conducts long-duration testing to simulate the infotainment unit's performance over extended periods, ensuring continuous operation reliability. By maintaining continuous testing action throughout the development cycle, the system ensures reliability without requiring separate discrete testing phases, optimizing time utilization.
3Strength
If functional components are tested under peak load conditions, then system robustness improves, but testing complexity increases
Solution Approach 1:
The stress testing platform is designed as a separate module within the overall testing system, dedicated specifically to testing functional components under maximum load capacity. This segmentation isolates the complex peak load testing scenarios from other testing activities, making the robustness evaluation process more manageable and systematic while maintaining high testing rigor.
