Solution Overview

Problem

Current digital model railway systems lack a method to effectively track and record the usage and operational parameters of model railway items, making it difficult to determine maintenance needs and simulate realistic usage profiles.

Innovation Solution

A method and digital model railway decoder that store time-dependent operating state parameters such as speed, distance, engine torque, and power in an event memory, allowing for the creation of usage profiles and facilitating maintenance by logging the operational data, which can be accessed by users and service personnel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If operating state parameters are stored in an event memory as a function of time, then information about usage and operational reliability is improved, but device complexity increases due to additional memory and processing requirements

Engineering Contradiction:
Improveoperational reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The model railway item autonomously records its own operating state parameters (speed, distance, engine torque, power) in its event memory without requiring external monitoring equipment. The item serves itself by automatically logging usage data, eliminating the need for complex external measurement and recording systems while improving reliability tracking.

Inventive Principle:
Principle #25Self-service

2Ease of repair

If time-dependent operating state parameters are recorded, then maintenance needs can be identified, but loss of time occurs due to data storage and processing requirements

Engineering Contradiction:
Improvemaintenance needs identificationVSAvoiddata storage and processing time
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The event memory continuously records operating state parameters during normal operation, so that when maintenance is needed, the data is already prepared and stored. This preliminary data collection eliminates the need for time-consuming measurements and data gathering during maintenance intervals, allowing service personnel to immediately assess usage and determine required maintenance tasks.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If an event memory is implemented in the model railway item, then usage profiles can be created, but manufacturing complexity increases

Engineering Contradiction:
Improveusage profile creationVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The event memory and signal processing device serve multiple functions: they record operating state parameters, create usage profiles, enable maintenance tracking, and provide operational reliability data. By making the decoder multi-functional, the patent avoids adding separate dedicated systems for each function, thereby reducing overall manufacturing complexity while achieving adaptability and versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The method involves engaging model railway articles (12) in different operating conditions during operation of a model railway system. An operating condition parameter is time-dependent stored during the operation of the model railway articles in an event storage of the model railway article. The operating condition parameter is stored at regular time intervals. The time intervals are predetermined by a user. Speed of an electric motor (16) of the model railway article is used for determining the operating condition parameter. An independent claim is also included for a digital model railway decoder for executing a method for operating a digital electrical model railway.
