Solution Overview

Problem

Conventional distributed computing systems lack a mechanism for dynamically updating message consumers to match the software component versions required for processing messages, leading to errors and manual updates by administrators.

Innovation Solution

A method where messages include component dependency identification, allowing a rules engine or update service to automatically download and install necessary software components in the message consumer, ensuring compatibility before processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual update mechanism is used, then system reliability is maintained through version matching, but system productivity deteriorates due to administrator intervention requirements

Engineering Contradiction:

Improveversion compatibilityVSAvoidmessage processing throughput

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The message consumer performs self-updating by automatically detecting version mismatches between its software components and the message queue, downloading required components, and installing updates without administrator intervention. This transforms the manual update process into an autonomous self-service mechanism that maintains version compatibility while eliminating human intervention bottlenecks.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary version checking before message processing by comparing the message consumer's software component versions against the required versions for the message queue. This preliminary detection enables proactive updates to be scheduled and executed before compatibility issues arise, ensuring reliability without interrupting ongoing message processing operations.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If automatic update mechanism is implemented, then system productivity improves through continuous operation, but device complexity increases due to update management components

Engineering Contradiction:

Improvemessage processing throughputVSAvoidupdate mechanism complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

A version information data structure serves as an intermediary between the message consumer and the update mechanism. This structured data contains version identifiers for all software components, enabling automated comparison and update determination without requiring complex real-time negotiation or verification protocols. The intermediary simplifies the update decision-making process while maintaining comprehensive version tracking.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The update mechanism is designed to handle multiple software component types uniformly through a single automated process. The same version checking, downloading, and installation procedures apply regardless of which specific component needs updating, reducing the complexity that would arise from maintaining separate update logic for different component categories.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If version checking is performed before each message processing, then reliability is improved through compatibility assurance, but time consumption increases

Engineering Contradiction:

Improvemessage processing compatibilityVSAvoidupdate execution time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Version compatibility checking is performed as a preliminary action before message processing begins. The system compares the message consumer's current software versions against the required versions and schedules updates in advance. This preliminary verification ensures that compatibility checks are completed once rather than repeatedly during each message processing operation, minimizing time consumption while maintaining reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The update scheduling mechanism dynamically adjusts update execution based on system conditions and message queue state. Rather than performing rigid pre-processing checks that block message handling, the system dynamically determines when updates can be safely scheduled and executed, allowing message processing to continue while updates are prepared and applied at optimal moments.

Inventive Principle:

Principle #15Dynamics

AI summary

A message is received at a message consumer, the received message having a component dependency identification that indicates a version of a software component that is necessary to process the message. The version of the software component is automatically downloaded if the message consumer does not already include the version of the software component. The version of the software component is then used to process the received message.
