Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing track gauge changing technology is used, then track changing can be performed, but the track changing stability and reliability are insufficient

Engineering Contradiction:

Improvetrack changing reliabilityVSAvoidtesting and verification

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent creates a test bench that replicates the actual track changing process of a train. The test bench includes a test carriage with wheel pairs that copy the behavior of actual train wheel pairs during track gauge changing, allowing reliable verification without requiring actual train tests

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The test bench is designed to perform multiple functions: it can test different wheel pair configurations, simulate various track gauge changing scenarios, and verify both the feasibility and stability of track changing. This multi-functional design enables comprehensive reliability verification in a single system

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a dual-drive wheel system is implemented, then continuous track changing feasibility can be verified, but the system complexity increases

Engineering Contradiction:

Improvecontinuous track changing feasibilityVSAvoiddual-drive wheel system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The dual-drive wheel system is divided into independent modular components: left drive wheel assembly, right drive wheel assembly, drive mechanisms, and measurement systems. Each module can be independently configured and tested, making the complex system manageable and verifiable

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces measurement rockers and force measurement sensors as intermediary devices between the drive wheels and the wheel pairs. These intermediaries transmit and measure the forces and movements, enabling verification of continuous track changing feasibility without directly complicating the drive mechanism itself

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If force measurement sensors are integrated into the rocker arm, then track changing force can be measured accurately, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The force measurement sensors are integrated directly into the measurement rockers, combining the measurement function with the existing mechanical structure. This merging approach allows accurate force measurement without adding separate, complex measurement systems

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces complex mechanical force transmission and measurement mechanisms with electronic force measurement sensors. The sensors electronically detect forces during track changing, substituting elaborate mechanical linkages and measurement devices with simpler electronic sensing elements

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
