Common Operating System Feature Set Dependency Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of dependencies among operating system components makes testing and modification costly and difficult, especially as the size of the operating system increases, due to a lack of effective dependency management during development cycles.
Innovation Solution
A common operating system feature set is established with a minimal memory footprint, organized into component groups with defined dependencies and API sets, including a hardware abstraction layer, kernel, dynamic link library layers, and a networking layer, to provide a reliable and flexible base for various configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating system includes a large number of components to provide comprehensive functionality, then the functionality and versatility are improved, but the complexity of dependencies among components increases, making testing and modification more costly and difficult
Solution Approach 1:
The patent segments the operating system into distinct layers (hardware abstraction layer, kernel, system services, application programs) with clearly defined interfaces between them. This segmentation reduces dependency complexity by establishing hierarchical boundaries where each layer has specific responsibilities and dependencies on lower layers, making the system more manageable and testable while maintaining comprehensive functionality.
2Adaptability or versatility
If the number of components in the operating system increases to cover more scenarios, then the adaptability is improved, but the testing cost and difficulty increase due to complex dependencies
Solution Approach 1:
By dividing the operating system into independent layers with well-defined interfaces, the patent enables modular testing where each layer can be tested separately. This reduces testing time and cost because dependencies are minimized and controlled through the hierarchical structure, allowing parallel testing of different layers without requiring complete system integration for each test.
Solution Approach 2:
The patent creates a universal kernel and hardware abstraction layer that can support multiple application programs and system services across different scenarios. This multi-functional base layer reduces testing requirements because the core infrastructure is tested once and then reused across various configurations, rather than requiring separate testing for each scenario.
3Adaptability or versatility
If comprehensive operating system services are provided through multiple components, then the service coverage is improved, but components at lower layers have access to fewer services due to hierarchical dependencies
Solution Approach 1:
The hierarchical segmentation allows lower layers to access services through well-defined interfaces and abstraction mechanisms. The hardware abstraction layer and kernel provide standardized service access points that lower-layer components can use without needing direct access to upper-layer services, maintaining ease of operation while preserving comprehensive service coverage.
