Solution Overview

Problem

Existing depalletization devices are complex, bulky, and lack flexibility in handling various geometric arrangements of pallet layers, resulting in inefficient disassembly and orientation of boxes, with limited precision and repeatability.

Innovation Solution

A depalletization device with a simplified design featuring an entry conveyor, loading/unloading device, exit conveyors, and a control system that uses motors and rollers to extract and orient layers and boxes, allowing for flexible handling of layers in any format by transferring entire layers onto alternating conveyors and using separate rollers to separate rows and columns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple conveyors and fixed obstacles are used to separate and orient boxes, then the boxes can be divided into groups and oriented, but the device becomes complex and bulky

Engineering Contradiction:
Improveability to handle various geometric arrangementsVSAvoidnumber of conveyors and obstacles
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device divides the layer into rows and columns using separate rollers that can be independently adjusted. The rollers are segmented into different sets (first rollers for rows, second rollers for columns) that can be positioned and configured separately, allowing flexible handling of various geometric arrangements without requiring a complete redesign of the entire conveyor system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rollers are made movable and adjustable rather than fixed. The position and configuration of the rollers can be dynamically changed to accommodate different layer formats and box arrangements. This dynamic capability allows the same device to handle multiple geometric configurations without adding permanent fixed obstacles for each possible arrangement.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If additional auxiliary devices are added to separate rows and columns, then the precision of separation improves, but the device complexity increases

Engineering Contradiction:
Improveprecision and repeatability of box orientationVSAvoidnumber of auxiliary devices
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The rollers serve multiple functions: they separate rows, separate columns, and orient boxes in different directions. The same roller mechanism can be configured to perform different separation tasks by adjusting their position and arrangement, eliminating the need for dedicated auxiliary devices for each specific separation function.

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

Solution Approach 2:

The device achieves precision through adjustable parameters such as roller position, spacing, and configuration rather than through complex mechanical structures. By changing the parameters of the existing rollers (their positions and arrangements), the system can precisely separate and orient boxes for different geometric arrangements without adding more devices.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If the device is designed to handle limited layer formats, then the design is simpler, but the flexibility to handle various geometric arrangements is reduced

Engineering Contradiction:
Improvesimplicity of building and maintainingVSAvoidflexibility with layer formats
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The roller positions and configurations are made adjustable rather than fixed for specific formats. This allows the same device to adapt to different layer formats and geometric arrangements by repositioning the rollers, providing flexibility without requiring multiple specialized devices for each format.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The roller system is designed to universally handle multiple layer formats and geometric arrangements through a single configurable mechanism. The same rollers can be repositioned and reconfigured to work with different box sizes, layer dimensions, and geometric patterns, making the device versatile while maintaining relative simplicity.

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