Innovation Solution

A transport unit for a shelf warehouse that includes a frame housing open on two sides, a storage area for temporary object storage, and a gripper with a means of interference and positioning tools, allowing for efficient storage and retrieval of components by minimizing relative movement and optimizing storage density.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If components are stored in a warehouse system with storage compartments, then components can be kept in stock for delivery to workstations, but the time required to deliver components from storage to goods issue point increases production inefficiency

Engineering Contradiction:
Improveproduction efficiencyVSAvoiddelivery time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The transport unit is pre-positioned at the goods issue point with its gripper ready to immediately retrieve components from storage compartments. The unit can quickly move between storage locations and the goods issue point, performing preliminary positioning actions that minimize delivery time without requiring complex real-time decision-making systems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The transport unit acts as an intermediary device between the storage compartments and the goods issue point. It features a gripper mechanism that can securely hold components during transit and a positioning device that ensures precise placement at the goods issue point, thereby streamlining the transfer process and reducing delivery time.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If a large number of different components are stored in a small space, then storage density increases, but access time to specific components increases

Engineering Contradiction:
Improvestorage capacityVSAvoidaccess time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The storage system is segmented into multiple storage compartments arranged in a compact configuration. Each compartment can be independently accessed by the transport unit's gripper, allowing for efficient retrieval of specific components without requiring access to the entire storage structure. This segmentation enables high storage density while maintaining quick access to individual components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transport unit employs a positioning device that operates in multiple dimensions to locate and retrieve components from densely packed storage compartments. By utilizing vertical and horizontal positioning capabilities, the system can access specific components in a compact three-dimensional storage arrangement, thereby maintaining both high storage capacity and rapid access times.

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

3Area of stationary object

If storage compartments are made compact to increase storage density, then space utilization improves, but the complexity of storing and retrieving diverse components increases

Engineering Contradiction:
Improvestorage spaceVSAvoidsystem complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The transport unit is designed as a universal device that can handle various types of components through its adaptable gripper mechanism. The gripper can adjust its gripping force and configuration to accommodate different component sizes and shapes, while the positioning device provides standardized multi-axis movement. This universality allows the system to manage diverse components in compact storage compartments without significantly increasing system complexity.

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