Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If AGV-based conveyor devices are used for highly variable conveying paths, then adaptability is improved, but conveying capacity deteriorates due to collision avoidance requirements

Engineering Contradiction:
Improveconveying path variabilityVSAvoidconveying capacity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The conveyor device is segmented into multiple independent rack elements that can be individually controlled. Each rack element can move objects independently, allowing parallel operations and eliminating the collision avoidance bottlenecks that limit AGV-based systems. This segmentation enables multiple objects to be conveyed simultaneously along different paths within the same system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs dynamic control where the conveying path and speed of each rack element can be adjusted in real-time based on destination requirements. Objects can be accelerated, decelerated, or redirected at different points along the conveyor tracks, enabling highly variable paths while maintaining high capacity through optimized object flow management.

Inventive Principle:
Principle #15Dynamics

2Productivity

If stationary conveyor units with conveyor drives are used, then conveying capacity is improved, but adaptability to variable conveying paths deteriorates

Engineering Contradiction:
Improveconveying capacityVSAvoidconveying path variability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

While maintaining the high capacity of stationary conveyor units, the system introduces dynamic path selection capabilities. Each rack element can be independently controlled to deliver objects to different destinations along the conveyor tracks, enabling the stationary infrastructure to adapt to variable conveying requirements without sacrificing capacity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conveyor tracks and rack elements are designed to serve multiple functions. The same physical infrastructure can handle both high-capacity bulk conveying and flexible individual object delivery to various destinations, making the system universally applicable to different intralogistics scenarios.

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

3Productivity

If multiple AGVs are increased to compensate for low conveying capacity, then conveying capacity is improved, but device complexity and costs deteriorate due to safety installations

Engineering Contradiction:
Improveconveying capacityVSAvoidsafety installations
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Instead of deploying multiple independent AGVs with their own safety systems, the invention uses multiple controlled rack elements that share a common control infrastructure. This approach achieves equivalent or superior capacity while avoiding the redundant safety installations that would be required for multiple autonomous vehicles.

Inventive Principle:
Principle #26Copying
