Solution Overview

Problem

Existing train detection systems on railway lines are inflexible, require multiple dedicated hardware units for different track circuit types, and are costly to maintain and adapt, especially in varying weather conditions, leading to inefficiencies and increased implementation times.

Innovation Solution

A system combining hardware and software units where a single processing and control unit, with interchangeable software programs, manages multiple interface units for different train detection methods, allowing adaptation to various track circuit types and conditions without replacing hardware, and enabling centralized management through a digital communication network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated hardware units are used for different track circuit types, then reliability is improved, but device complexity and cost increase

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single hardware platform that can perform multiple track circuit functions through software configuration. The operating unit includes a processor and memory that can be programmed to support different track circuit types (audio frequency, impulsive, axle counting, communication), eliminating the need for separate dedicated hardware units for each function while maintaining reliability through standardized architecture.

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

Solution Approach 2:

The patent utilizes parameter changes by modifying software parameters and configuration settings rather than hardware components to adapt the operating unit to different track circuit types. The system changes operational parameters through software updates, allowing the same physical hardware to function differently based on programmed parameters, thus reducing complexity while preserving reliability.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If dedicated hardware units are used for different track circuit types, then functional capability is improved, but adaptability to weather conditions deteriorates

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the operating unit adaptable through software updates rather than fixed hardware design. The system can dynamically adjust its functionality to respond to different weather conditions and track circuit requirements by loading different software configurations, enabling the same hardware to adapt to changing environmental conditions without physical modification.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses universality to create a single operating unit that can handle multiple track circuit types and weather conditions through software programming. This universal design allows the system to adapt to various operational scenarios including different weather conditions without requiring separate dedicated hardware for each scenario, thereby improving adaptability while managing complexity.

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

3Adaptability or versatility

If hardware replacement is performed to adapt to new track circuit technologies, then adaptability is improved, but loss of time and cost increase

Engineering Contradiction:
ImproveadaptabilityVSAvoidimplementation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies copying by using software copies or virtual images to represent different track circuit technologies within the same hardware platform. Instead of physically replacing hardware units, the system creates software-based representations of different track circuit types that can be loaded and executed on the existing hardware, enabling rapid adaptation without physical replacement and thus reducing implementation time.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent utilizes parameter changes by modifying software parameters and configuration files to adapt the operating unit to new track circuit technologies. This approach allows the system to change its operational characteristics through software updates rather than hardware replacement, significantly reducing the time required for adaptation and eliminating associated costs.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If multiple dedicated operating units are installed for different track circuit types, then functional capability is improved, but device complexity and cost increase

Engineering Contradiction:

Solution Approach 1:

The patent applies universality by designing a single operating unit that can perform multiple track circuit functions through software configuration. The operating unit includes a processor and memory that can be programmed to support different track circuit types (audio frequency, impulsive, axle counting, communication), eliminating the need for separate dedicated hardware units for each function while maintaining functional capability.

Inventive Principle:

Solution Approach 2:

The patent uses merging by combining multiple track circuit functions into a single integrated operating unit. Instead of having separate hardware units for different track circuit types, the system merges these functions into one unified platform that can execute different operational modes through software, thereby reducing overall system complexity while preserving full functional capability.

Inventive Principle:
Principle #5Merging (Combining)
