Solution Overview

Problem

Existing packaging methods for fibrous materials, such as cellulose acetate tow bales, are complex, expensive, and prone to failure due to high internal pressures, often requiring heat sealing, vacuum sealing, or additional restraints like straps, which can be dangerous and inefficient.

Innovation Solution

A method involving placing a fibrous material between an upper and lower sheet, folding the sheets to create overlapping edges, and applying a perimeter tape with an adhesive layer to secure them, which can withstand internal pressures without additional restraints or sealing methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heat sealing or vacuum sealing methods are used to package fibrous materials, then packaging reliability is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improvepackaging reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the complex heat sealing and vacuum sealing equipment from the packaging system. Instead of using these complex sealing methods, the patent employs simple adhesive tapes to secure the packaging sheets, thereby maintaining packaging reliability while dramatically reducing device complexity and manufacturing costs.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces expensive, complex sealing equipment with inexpensive adhesive tapes. The tapes serve as disposable, simple fastening elements that effectively secure the packaging without requiring complex sealing machinery, thus resolving the contradiction between reliability and device complexity.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Strength

If additional restraints like straps are used to withstand internal pressure, then packaging strength is improved, but device complexity and safety risks increase

Engineering Contradiction:

Improvepackaging strengthVSAvoiddevice complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The invention merges the functions of multiple separate components (packaging sheets and restraining straps) into a single integrated system. The packaging sheets themselves are designed to withstand internal pressure through proper folding and adhesive bonding, eliminating the need for separate restraining straps and thereby reducing device complexity while maintaining packaging strength.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The packaging sheets serve multiple functions simultaneously: they contain the fibrous material, resist internal expansion pressure, and provide structural integrity. This multi-functionality eliminates the need for additional restraining components, resolving the contradiction between strength and device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If excessive compression is applied to reduce bale height, then transport efficiency is improved, but packaging material stress increases

Engineering Contradiction:

Improvetransport efficiencyVSAvoidpackaging material stress

Core Design Contradiction:

ProductivityVSStress or pressure

Solution Approach 1:

The invention applies adhesive tapes to the packaging sheets before the fibrous material undergoes excessive compression during baling. This pre-application of adhesive bonding provides cushioning and stress distribution, allowing the packaging to withstand the high compression forces required for transport efficiency without failing due to excessive stress concentration.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The packaging system uses composite construction with multiple sheets and adhesive tapes working together. This composite structure distributes compression stresses across multiple layers and bonding points, enabling the packaging to handle excessive compression for improved transport efficiency while preventing stress-induced failure of individual components.

Inventive Principle:

Principle #40Composite materials
