Solution Overview

Problem

Existing service frameworks for developing application services face challenges in managing module dependencies and compatibility, particularly when modifications to one module affect dependent modules.

Innovation Solution

A computer-implemented method for a service framework that provides modules of a module stack to clients, determines if the provided module has been modified, and supplies dependency data to ensure compatibility and manage dependencies between modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If modules are provided to clients without dependency tracking, then the service framework is simpler and faster, but modifications to one module cause difficulties in dependent modules

Engineering Contradiction:

Improvemodule deployment speedVSAvoidmodule compatibility

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The service framework performs preliminary action by determining dependency data before providing modules to clients. The framework proactively identifies which modules depend on the provided module and prepares compatibility information in advance, preventing compatibility issues before they occur during module execution.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The service framework implements feedback by determining whether the provided module has been modified by the client and using this information to adjust the module provision process. The framework continuously monitors module modifications and updates dependency tracking accordingly, ensuring compatibility is maintained throughout the module lifecycle.

Inventive Principle:

Principle #23Feedback

2Reliability

If dependency data is determined and provided for all modules, then module compatibility is improved, but the service framework complexity increases

Engineering Contradiction:

Improvemodule compatibilityVSAvoidservice framework structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The service framework applies segmentation by handling dependency data determination on a per-module basis rather than requiring comprehensive analysis of the entire module stack. The framework determines dependency data only for the provided module and its direct dependencies, breaking down the complex task into manageable segments that can be processed independently.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The service framework uses an intermediary approach by introducing dependency data as a separate, structured component that mediates between the provided module and dependent modules. This dependency data structure acts as an intermediary layer that contains compatibility information, allowing the framework to manage complexity through organized information storage and retrieval rather than direct complex interactions between all modules.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the service framework provides detailed service interface data including service proxy and service stub data, then client-accessibility and communication reliability are improved, but the data transmission volume and processing requirements increase

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidinterface data volume

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The service framework performs preliminary action by providing service interface data, including service proxy and service stub data, in advance before the client needs to access the module. This advance provision of interface information ensures communication reliability is established beforehand, allowing the client to properly configure connections and understand the module interface contract without delay.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The service interface data serves multiple functions simultaneously: it defines the communication contract between client and module, provides connection management information, specifies buffer allocation requirements, and outlines data serialization formats. By consolidating these multiple functions into a single interface data structure, the framework reduces the total quantity of separate data transmissions needed while maintaining comprehensive communication reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A computer-implemented method for a service framework to develop application services, including: providing at least one module of a module stack to a client; determining if the provided module has been modified by the client; determining dependency data, at least including information on the dependency of further modules of the module stack from the provided module; and providing the dependency data of the other modules of the module stack from the provided module.
