Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple conveyor technologies are used in existing storage systems, then loading units can be transported and handled, but the system becomes complex and expensive with long travel times

Engineering Contradiction:
Improvematerial flow handling efficiencyVSAvoidconveyor system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the functions of storage and retrieval machines (SRM) and line conveyor technology into a single integrated storage structure. The bearing structures with rotated orientations serve dual purposes: storing loading units and transporting them between levels, eliminating the need for separate conveyor systems while reducing complexity and improving efficiency

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bearing structures are designed to perform multiple functions simultaneously: they provide storage capacity for loading units, enable vertical transport between storage areas, and facilitate horizontal movement within levels. This multi-functionality replaces traditional separate conveyor systems, reducing overall system complexity

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

2Ease of manufacture

If conventional SRM and line conveyor technology are used separately, then loading units can be stored and transported, but the system requires extensive infrastructure and high costs

Engineering Contradiction:
Improvesystem implementation costVSAvoidhandling system structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges SRM and line conveyor functions into a single bearing structure system. The first and second bearing structures with rotated orientations integrate storage and transport capabilities, eliminating the need for separate conveyor infrastructure and reducing implementation costs

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces rotational orientation between bearing structures as a new dimensional approach. By rotating the second bearing structure relative to the first, the system achieves efficient three-dimensional space utilization and direct access to loading units, eliminating the need for extensive linear conveyor infrastructure

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

3Area of stationary object

If loading units are transferred between vertically stacked storage areas, then space utilization improves, but travel time increases without efficient transfer mechanisms

Engineering Contradiction:

Core Design Contradiction:
Area of stationary objectVSLoss of time

Solution Approach 1:

The patent uses rotational orientation of bearing structures to create direct access paths between vertically stacked storage areas. The rotated second bearing structure enables loading units to be transferred efficiently between levels without following lengthy horizontal conveyor paths, reducing travel time while maintaining vertical space utilization

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

AI summary

The invention relates to a storage system having a storage arrangement for storing loading units, and to a method for shifting loading units in a storage system. In order to simplify transporting operations during the shifting of loading units (3) in a storage system (1) having a storage arrangement (2), provision is made for the storage arrangement (2) to have at least a first storage region (4) and a second storage region (5), which is arranged vertically (6) above the first storage region (4). The first storage region (4) has a first storage structure (8), which is formed by first storage and retrieval routes (7); the second storage region (5) has a second storage structure (10), which is formed by second storage and retrieval routes (9). A first orientation (11) of the first storage structure (8) is rotated in relation to a second orientation (12) of the second storage structure (10). During the operation of shifting the loading units (3) in the storage system (1), a loading unit (3) is stored in or retrieved from (110) one of the two storage regions (4, 5) of the storage system (1) and transported (120) in said storage region (4, 5). The loading unit (3) is transferred (130) out of the one storage region (4, 5) into the other storage region (4, 5) and the storage unit (3) is transported (140) in the other storage region (4, 5).
