Solution Overview

Problem

Current model railroad control systems lack remote control capabilities and compatibility with various digital command control (DCC) command stations, limiting user control and flexibility in operating model trains.

Innovation Solution

A throttle emulator system that includes an emulator module with a DCC interface for connection to a DCC command station, enabling wireless communication with mobile electronic devices for remote control, and accommodating different connector types for compatibility with multiple DCC systems, allowing users to control model vehicles through a user interface on their devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a DCC command station is used to control model trains, then digital control capabilities are improved, but compatibility with different connector types is reduced

Engineering Contradiction:
Improvedigital control capabilitiesVSAvoidcompatibility with different connector types
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The throttle emulator is designed with multiple interchangeable DCC interfaces (e.g., NCE, DecoderPro, ESU, LocoNet connectors) that can be swapped to accommodate different DCC command station types. This allows a single device to work with multiple proprietary connector standards, making the system universal across different manufacturers while maintaining full digital control capabilities.

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

2Measurement precision

If direct control of model trains is implemented, then control precision is improved, but remote control capability is reduced

Engineering Contradiction:
Improvecontrol precisionVSAvoidremote control capability
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The throttle emulator acts as an intermediary device between the mobile device and the DCC command station. It receives control signals wirelessly from the mobile device via Wi-Fi or Bluetooth, processes them, and transmits the corresponding DCC commands to the command station. This intermediary approach maintains precise digital control while enabling remote operation through mobile devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple mobile devices are allowed to control the model train, then user accessibility is improved, but interference between devices is increased

Engineering Contradiction:
Improveuser accessibilityVSAvoidinterference between devices
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The throttle emulator implements a feedback mechanism where it monitors which mobile device is currently authorized to control the model train. When a user logs in through the web interface, the emulator establishes a unique communication session and filters commands to respond only to that specific device. This feedback-based device identification and session management prevents interference between multiple devices while maintaining broad user accessibility.

Inventive Principle:
Principle #23Feedback

AI summary

A throttle emulator system for a model vehicle includes an emulator module and a DCC interface having a connector to permit connection with a DCC command station. The DCC command station is configured to provide digital signals to control the model vehicle. The emulator module is coupled to the DCC interface and configured to transmit command and control signals to the DCC command station, via the DCC interface. The command and control signals are relayed by the DCC command station to control the model vehicle. The emulator module is further configured for wireless communication with a mobile electronic device such that a user can communicate with the emulator module to control the model vehicle through an interface on the mobile electronic device.
