Model Car Track Circuit Arrangement for Constant Power Supply

Solution Overview

Problem

Model car racing tracks with existing circuit arrangements do not provide a constant supply voltage for electrical consumers like pit stop modules or lap counters, leading to potential interruptions due to battery exhaustion.

Innovation Solution

A circuit arrangement where the positive and negative busbars of two tracks are directly connected to the supply terminals, providing a constant DC voltage for electrical consumers, eliminating the need for batteries and ensuring uninterrupted power supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrical consumers are powered by batteries in the prior art circuit, then they can operate independently, but the operation may be interrupted due to battery exhaustion

Engineering Contradiction:

Improvepower supply reliabilityVSAvoidbattery operating time

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The invention extracts the battery from the power supply system and replaces it with a direct connection to the track's existing DC supply voltage. The electrical consumer is connected between the positive and negative busbars that are already present on the track, eliminating the need for separate battery power sources at each consumer location.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The track's existing busbar system, originally designed solely for powering model cars, is made multi-functional by using it to also power electrical consumers. The positive and negative busbars serve dual purposes: propelling model cars and supplying power to stationary consumers simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple batteries are used to power electrical consumers on the track, then each consumer can operate independently, but the device complexity increases

Engineering Contradiction:

Improveconsumer placement flexibilityVSAvoidpower supply structure

Core Design Contradiction:
