Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If unpowered loading vehicles are used, then the structure is simple and cost is low, but movement flexibility is poor and automation degree is low

Engineering Contradiction:
Improvemovement flexibilityVSAvoidvehicle structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vehicle is divided into modular components: power module, running gear, frame structure, and control systems. Each module can be independently configured or removed, allowing the vehicle to transition between powered and unpowered modes, thus improving flexibility without permanently increasing structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vehicle incorporates a detachable power module that can be connected or disconnected from the running gear based on operational requirements. This dynamic configuration allows the same vehicle structure to adapt between different operating modes (self-powered or locomotive-pulled), enhancing movement flexibility.

Inventive Principle:
Principle #15Dynamics

2Productivity

If unpowered loading vehicles are used, then the vehicle structure is simple, but transfer efficiency is low and operation time is long

Engineering Contradiction:
Improvetransfer efficiencyVSAvoidvehicle structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The vehicle is pre-equipped with a power module and control systems that are ready for activation. When operational conditions require faster transfer, the power module can be engaged without requiring structural modifications or additional assembly, thus improving transfer efficiency while maintaining relatively simple baseline structure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The vehicle can autonomously control its own power module through the onboard control system, which automatically manages power distribution to running gears and coordinates with positioning and coupling systems. This self-service capability reduces the need for external assistance during transfers, improving efficiency without proportionally increasing structural complexity.

Inventive Principle:
Principle #25Self-service

3Extent of automation

If manual driving is adopted, then the control system is simple, but automation degree is low and labor cost is high

Engineering Contradiction:
Improvedriving automationVSAvoidcontrol system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The onboard control system serves multiple functions: it controls the power module, manages the running gears, coordinates the automatic coupler, and integrates with the positioning system. This multi-functional control architecture achieves high automation without requiring separate dedicated systems for each function, thus limiting the increase in overall control system complexity.

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

Solution Approach 2:

The control system continuously receives feedback from sensors monitoring vehicle position, power module status, and running gear conditions. This feedback enables automated adjustment and coordination of various subsystems, achieving high-level automation through intelligent control rather than through mechanical complexity.

Inventive Principle:
Principle #23Feedback

4Productivity

If repeated withdraws from ongoing journey are required during container transfer, then the vehicle can adapt to transfer operations, but operation time increases and efficiency decreases

Engineering Contradiction:
Improvecontainer transfer efficiencyVSAvoidoperation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The vehicle maintains continuous movement capability through its self-powered operation. The power module enables the vehicle to proceed directly to container transfer locations without needing to withdraw from the ongoing journey and wait for locomotive availability, thus maintaining continuous useful action and improving transfer efficiency while reducing operation time.

Inventive Principle:
Principle #20Continuity of useful action
