Solution Overview

Problem

Current palletizing methods require specialized article handling heads for each different article size, leading to high costs and operational disruptions, and are unable to efficiently accommodate uniquely sized articles due to the need for multiple heads and time-consuming modifications.

Innovation Solution

A method using a pair of opposed planar gripping members that can apply compressive force to articles of varying sizes, allowing for the formation of article arrays and pallets without the need for multiple heads, by positioning and manipulating the gripping members to accommodate different article arrangements and sizes within the same handling head.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If specialized article handling heads are used for each different article size, then the palletizing precision and reliability are improved, but the device complexity and cost increase, and the adaptability decreases

Engineering Contradiction:
Improvepalletizing reliabilityVSAvoidhandling head complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal handling head design with a compliant gripper that can accommodate multiple article sizes and configurations through electronic control and force feedback, eliminating the need for multiple specialized heads while maintaining reliable palletizing performance across different article types

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

2Manufacturing precision

If multiple specialized article handling heads are constructed for different article sizes, then the manufacturing precision for specific article types is improved, but the loss of time for head changes and the adaptability worsen

Engineering Contradiction:
Improvearticle placement precisionVSAvoidhead change time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The handling head incorporates a compliant gripper with force feedback control that dynamically adjusts its gripping force and position to accommodate different article sizes and configurations, allowing the system to adapt to various article types without physical head changes while maintaining precise placement

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses electronic control to dynamically adjust gripping parameters such as force magnitude and application points based on detected article characteristics, enabling the same physical head to achieve precise manipulation across different article sizes without mechanical reconfiguration

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If specialized article handling heads are used for each article type, then the ease of operation for specific article types is improved, but the adaptability to handle uniquely sized articles worsens

Engineering Contradiction:
Improvehandling operation easeVSAvoidarticle size adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The handling system incorporates sensors and force feedback that allow the gripper to automatically detect and adapt to different article characteristics during operation, eliminating the need for manual head selection or configuration while maintaining ease of use across different article types

Inventive Principle:
Principle #25Self-service
