Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing load wrapping technologies struggle to accommodate specialized load requirements efficiently, particularly in cases where loads deviate from standard cuboid shapes or have unique features like corner boards, top sheets, or irregular layers, often requiring dedicated and costly machinery that is not practical for all applications.

Innovation Solution

The implementation of a method and apparatus that utilize wrap profiles with controlled cycle interruptions, allowing for manual operator interventions and adjustments during the wrapping process, such as pausing, changing speed, or altering the dispense rate, to handle specialized load requirements without the need for expensive machinery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If dedicated machinery is used to handle specialized load requirements, then the ability to handle specialized loads (corner boards, top sheets, irregular layers) is improved, but the cost and device complexity increase significantly

Engineering Contradiction:

Improveability to handle specialized load requirementsVSAvoidcost and complexity of dedicated machinery

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system is designed to perform multiple functions by selecting from different wrap profiles that can handle various load configurations (standard loads, loads with corner boards, loads with top sheets, irregular layers) using the same basic wrapping machinery, eliminating the need for dedicated specialized equipment for each load type

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If a standard wrapping cycle is used for all loads, then the productivity and efficiency are improved, but the ability to accommodate specialized load requirements deteriorates

Engineering Contradiction:

Improvewrapping speed and efficiencyVSAvoidability to accommodate specialized load requirements

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts wrapping parameters and cycle characteristics by selecting different wrap profiles based on load requirements. The control system can modify wrap speed, wrap pattern, and operational parameters in real-time to accommodate specialized loads while maintaining high productivity through automated profile selection

Inventive Principle:

Principle #15Dynamics

3Productivity

If wrap parameters are optimized for standard loads, then the wrapping efficiency is improved, but the suitability for specialized loads deteriorates

Engineering Contradiction:

Improvewrapping efficiencyVSAvoidsuitability for specialized load configurations

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system changes operational parameters by selecting from multiple predefined wrap profiles, each optimized for specific load types. The control system adjusts wrap speed, wrap pattern, tension, and other parameters based on the selected profile, allowing efficient wrapping of both standard and specialized loads without sacrificing optimization

Inventive Principle:

Principle #35Parameter changes
