OS-Independent Device Driver Framework for Enterprise Hardware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device drivers are often OS specific, device type specific, and manufacturer specific, making it difficult to seamlessly deploy new OS or hardware devices in enterprise environments, requiring frequent modifications to legacy applications and lacking a common software driver stack across business verticals.
Innovation Solution
Development of an OS-independent device driver framework that provides a normalized interface for application access to peripheral devices, utilizing a loader to execute within its own processing context, allowing interactions through an OS-independent interface and enabling sharing across applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device drivers are made OS specific to ensure proper device operation and security, then device reliability and security are improved, but adaptability and ease of deployment deteriorate
Solution Approach 1:
The patent introduces an intermediary layer called the 'device driver framework' that mediates between applications and peripheral devices. This framework provides a standardized interface that translates OS-specific driver calls into a common language, allowing applications to interact with devices without needing OS-specific driver implementations. The framework acts as a universal translator that maintains reliability while enabling cross-OS compatibility.
Solution Approach 2:
The device driver framework is designed to be universal, serving multiple operating systems (Windows, Linux, macOS) and multiple device types through a single standardized interface. The framework implements a plug-and-play architecture where devices are registered with the framework, which then automatically handles device-specific operations through standardized abstractions, eliminating the need for separate drivers for each OS and device type.
2Reliability
If separate device drivers are provided for each OS and device type, then device-specific functionality is optimized, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent segments the device driver functionality into distinct modular components: a universal framework layer, device-specific plugin layers, and application interface layers. Each segment handles specific responsibilities independently, allowing the system to maintain device-specific optimization while reducing overall complexity through modular architecture. The framework handles common operations, while device-specific plugins only implement what is unique to each device type.
Solution Approach 2:
The patent merges multiple separate driver implementations into a single unified framework that can handle different device types. Instead of having separate driver stacks for Windows, Linux, macOS and for different device categories, the framework combines these into one integrated system where device-specific functionality is implemented through standardized interfaces and plugin mechanisms.
3Adaptability or versatility
If legacy applications are modified to support new OS or hardware interfaces, then adaptability to new systems is improved, but loss of time and development effort increase
Solution Approach 1:
The device driver framework serves as an intermediary that shields legacy applications from OS and hardware changes. Applications continue to use the standardized framework interface rather than being directly coupled to OS-specific APIs or hardware devices. When OS updates or new hardware is introduced, only the framework needs updating, not the applications, as the framework absorbs the changes through its abstraction layer.
Solution Approach 2:
The framework performs preliminary action by pre-implementing standardized interfaces and device registration mechanisms before applications need to interact with new OS versions or hardware. The framework establishes the communication protocols and abstraction layers in advance, so applications can immediately use the framework without modification when new hardware or OS versions are deployed.
4Reliability
If manufacturer-specific device drivers are used to optimize performance, then device performance is improved, but ease of manufacture and deployment across different verticals deteriorate
Solution Approach 1:
The framework provides a universal platform that can be deployed across different business verticals and device types using the same standardized interface. Manufacturers can register their devices with the framework once, and the same framework implementation serves all verticals (retail, healthcare, finance, etc.) without requiring separate driver stacks for each industry or device category.
Solution Approach 2:
The framework allows device performance optimization through parameter changes rather than different implementations. Device-specific performance tuning is achieved by modifying configuration parameters and registration details within the unified framework, rather than creating separate driver codebases. This enables manufacturers to optimize performance for specific devices while maintaining the same overall architecture and deployment process.

AI summary
A device driver is configured to provide access to at least one peripheral device through a normalized interface. A loader is provided with the device driver. When the loader is executed, the loader loads the device driver to an operating system (OS) within its own independent processing context. The interactions through the normalized interface are OS independent.
