Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Embedded software systems lack standardized guidelines for exception and event management, leading to inconsistencies and unreliability due to the complexity of multiple layers and components developed by different teams, resulting in unhandled exceptions and compromised system reliability.
Innovation Solution
A method and architecture for exception and event management that includes a dedicated software framework with a unique base ID for user registration, hierarchical reporting, logging, and handling, using an EEM module to identify, report, and handle exceptions and events across various layers, ensuring consistent and reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multitude of layers and components are used in embedded software systems, then the system functionality and versatility are improved, but the consistency and reliability of exception and event management deteriorate
Solution Approach 1:
The patent applies universality by creating a standardized exception and event management framework that works across all layers and components of the embedded software system. The framework defines universal interfaces, common data structures, and standardized handling procedures that can be applied consistently throughout the diverse system architecture, ensuring that exception management behaves predictably regardless of which layer or component generates the exception.
Solution Approach 2:
The patent implements homogeneity by establishing uniform exception and event management practices across heterogeneous system components. Through standardized APIs, consistent logging formats, and unified handling mechanisms, the framework ensures that exceptions are identified, reported, and managed in a homogeneous manner throughout the entire software stack, eliminating the variability that arises from different teams implementing their own ad-hoc approaches.
2Adaptability or versatility
If different teams or developers develop various layers and components, then the system complexity and adaptability are improved, but the consistency in exception identification, reporting, logging and handling deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the exception management system into distinct, well-defined modules and layers. Each team can develop their component independently using the standardized interfaces, while the framework provides clear boundaries and contracts between components. This segmentation allows parallel development by multiple teams without requiring complex coordination, as each team works within their own module boundaries while adhering to the universal interface specifications.
3Ease of manufacture
If no standardized guidelines are provided for exception management, then the ease of implementation is improved, but the system reliability and debugging efficiency deteriorate
Solution Approach 1:
The patent applies preliminary action by establishing standardized exception management guidelines, interfaces, and frameworks before the actual system implementation begins. The framework pre-defines exception data structures, reporting formats, logging procedures, and handling protocols that all developers must follow. This preliminary standardization ensures that reliability is built into the system from the ground up, while developers can still implement their components easily by simply adhering to the pre-established conventions rather than designing their own exception management approaches.
Data Source
AI summary
A method for providing a dedicated software framework for exception and event management in an embedded software system is disclosed. In one embodiment, each of exceptions/events originated from users are uniquely identified and severity of the exceptions/events is categorized. The users are software subsystems, software layers and software modules in the embedded software system. Further, information regarding the exceptions/events is reported through various layers, subsystems and modules for use by an application. Furthermore, information associated with one or more of the reported exceptions/events is logged using a logging framework. In addition, the exceptions/events are handled to keep applications running without causing an unexpected behavior in the embedded software system.
