Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling and stacking of oil pipes is used, then operators can directly stack pipes, but labor intensity increases and safety factors decrease

Engineering Contradiction:

Improveease of operationVSAvoidsafety factors

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The oil pipe handling device enables self-service operation where the mechanical system automatically grasps, transports, and stacks oil pipes without requiring manual handling by operators, thereby reducing labor intensity while maintaining operational simplicity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical handling system with an automated mechanical handling device that uses grasping assemblies, positioning members, and controlled movement mechanisms to manipulate oil pipes, improving both ease of operation and safety factors

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If manual stacking of oil pipes is performed, then flexibility in handling is maintained, but working efficiency decreases

Engineering Contradiction:

Improveflexibility in handlingVSAvoidworking efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The handling device incorporates dynamic components including movable grasping assemblies, adjustable positioning members, and controllable movement along rails, enabling the system to adapt to different oil pipe configurations while maintaining high working efficiency through automated operation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent designs a universal handling device that can process oil pipes of different specifications through adjustable grasping mechanisms and positioning systems, providing both flexibility in handling various pipe types and high productivity through automated stacking operations

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If operators manually handle oil pipes, then direct control is achieved, but labor intensity increases and safety risks increase

Engineering Contradiction:

Improvedirect controlVSAvoidsafety risks

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary mechanical handling system that acts as a mediator between operators and oil pipes, allowing operators to control the stacking process through the mechanical device while avoiding direct contact with heavy pipes, thereby reducing safety risks while maintaining operational control

Inventive Principle:

Principle #24Intermediary (Mediator)

4Extent of automation

If vertical-type handling devices are used, then automation is achieved, but horizontal stacking capability is lost

Engineering Contradiction:

ImproveautomationVSAvoidhorizontal stacking capability

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The patent transitions from vertical-type handling to a horizontal stacking configuration by designing the base with horizontal bearing areas and positioning members arranged to support oil pipes in a horizontal orientation, while maintaining automation through the movable grasping assembly that operates along horizontal rails

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
