Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional gripping apparatuses are used, then the lifting and transporting equipment can grip intermodal containers, but the positioning accuracy is poor and working time is excessive

Engineering Contradiction:
Improvepositioning accuracyVSAvoidworking time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The gripping apparatus employs movable gripping means that can dynamically adjust their position and orientation through multiple degrees of freedom (linear and angular movements). This dynamic capability allows the apparatus to adapt to positioning variations and achieve accurate container engagement without requiring extremely precise pre-positioning of the lifting equipment, thereby reducing the time needed for positioning adjustments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The apparatus changes its operational parameters by allowing the gripping means to move along linear paths and rotate through angular ranges. This parameter flexibility enables the system to compensate for positioning errors and achieve accurate gripping through adaptive adjustment rather than relying solely on fixed, precise positioning of the lifting equipment itself.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If traditional gripping apparatuses are used, then the lifting and transporting equipment can grip intermodal containers, but the device complexity is high with many components

Engineering Contradiction:
Improvegripping reliabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gripping means is designed as a multi-functional unit that combines multiple gripping functions within a single integrated structure. By consolidating various gripping actions into one versatile mechanism, the apparatus maintains reliable container gripping capability while reducing the total number of separate components needed in the system.

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

Solution Approach 2:

The patent merges the gripping functions into a unified gripping means structure that integrates multiple operational capabilities. This consolidation approach maintains the reliability of the gripping system while minimizing device complexity by eliminating redundant separate components and streamlining the overall structure.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If traditional gripping apparatuses are used, then the lifting and transporting equipment can grip intermodal containers, but the maneuverability is limited and operational accuracy is reduced

Engineering Contradiction:
ImprovemaneuverabilityVSAvoidoperational accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The gripping means incorporates multiple degrees of freedom including linear movements and angular rotations, providing dynamic adaptability during operation. This dynamic capability enhances both maneuverability (ease of operation) and operational accuracy by allowing real-time adjustments to accommodate variations in container positioning and gripping requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gripping apparatus operates across multiple dimensions by combining linear translations with angular rotations. This multi-dimensional movement capability significantly improves maneuverability and operational accuracy compared to single-axis mechanisms, as it allows the gripping means to approach and engage containers from various orientations and positions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
