Solution Overview

Problem

Current software packages for managing diagnostic messages from vehicle fleets, particularly rail vehicle fleets, are inflexible and time-consuming to update, requiring the creation of new packages for adjustments and updates.

Innovation Solution

A software package structure with a first, unchangeable part containing a large number of diagnostic messages and a second, customizable part that can be updated after creation, allowing users to add, delete, or change information, enabling flexible management and keeping diagnostic information up to date.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a software package is created with all diagnostic messages stored during creation, then the software package is complete and ready for use, but any adjustments or updates require creating a new software package which is time-consuming

Engineering Contradiction:

Improveflexibility to update diagnostic informationVSAvoidtime for creation and release of new software package

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The software package is divided into two distinct parts: a first part containing the core diagnostic messages that remain unchanged, and a second part containing diagnostic information that can be updated independently. This segmentation allows the information part to be modified without recreating the entire software package, thus resolving the contradiction between completeness and updatability.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the software package is made immutable after creation to ensure stability, then reliability is improved, but the ability to update and customize diagnostic information is lost

Engineering Contradiction:

Improvestability of software packageVSAvoidcapability to adjust and update

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

By segmenting the software package into an immutable first part (diagnostic messages) and a mutable second part (diagnostic information), the patent achieves both reliability through the stable core and adaptability through the updatable information section.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the software package are assigned different properties: the first part is fixed and stable while the second part is flexible and updatable. This local differentiation of qualities allows the system to simultaneously maintain reliability and adaptability in appropriate sections.

Inventive Principle:

Principle #3Local quality

AI summary

The invention relates to a method for managing diagnostics messages (A, B, C, D) and diagnostics information (IA, IC, ID) of a vehicle fleet (6), in particular of a rail vehicle fleet (6), using a software package (14). In order to achieve an improved method for managing diagnostics messages (A, B, C, D) and diagnostics information (IA, IC, ID), according to the invention a plurality of diagnostics messages (A, B, C, D) for the vehicles (8) in the vehicle fleet (6) are stored in a first part (16) of the software package (14) when the software package (14) is created. Furthermore according to the invention, information (IA, IC, ID) at least for some of the diagnostics messages (A, B, C, D) is stored (36) and/or amended (34) in a second part (22) of the software package (14) after the software package (14) has been created.
