Solution Overview

Problem

Existing methods for compacting apparel for packaging are inefficient in reducing volume, resulting in bulky packages that are not space-effective for retail display and storage.

Innovation Solution

A method involving the use of a hydraulic press to apply high pressures in multiple compression steps, forming a rigid bundle of compacted apparel that retains its shape, which can then be shrink-wrapped for further protection and display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional compaction methods are used for apparel packaging, then the packaging process is simple, but the volume reduction is insufficient resulting in bulky packages

Engineering Contradiction:
Improvepackage volumeVSAvoidcompaction process complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The compaction process is divided into multiple sequential compression steps rather than a single operation. Each step applies pressure progressively to the apparel stack, allowing gradual volume reduction while maintaining control over the compaction process and preventing damage to the garments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The compaction employs periodic compression cycles where pressure is applied, held, and released in sequence. This periodic action allows the apparel to be compressed incrementally over multiple cycles, achieving significant volume reduction (up to 44%) while maintaining fabric integrity through controlled pressure application and release intervals.

Inventive Principle:
Principle #19Periodic action

2Volume of moving object

If high pressure compression is applied to reduce volume, then space efficiency improves, but the apparel may be damaged

Engineering Contradiction:
Improvebundle volumeVSAvoidapparel integrity
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The apparel is pre-folded into a compact stack before compression, creating an initial structured form that guides the compression process. This preliminary arrangement ensures that the subsequent high-pressure compression acts uniformly on the material, reducing volume efficiently while preventing damage through controlled pressure distribution.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The compression process uses dynamic pressure control where the hydraulic press adjusts pressure levels during the compression cycles. Pressure is applied progressively and held at specific levels for predetermined times, then released, allowing the system to adapt pressure dynamically to the compression stage, achieving volume reduction while maintaining apparel integrity through controlled mechanical action.

Inventive Principle:
Principle #15Dynamics

3Volume of moving object

If multiple compression steps are used to achieve significant volume reduction, then space efficiency improves, but processing time increases

Engineering Contradiction:
Improvecompacted volumeVSAvoidcompaction processing time
Core Design Contradiction:
Volume of moving objectVSLoss of time

Solution Approach 1:

The compression process maintains continuous useful action through overlapping compression cycles. While one compression step is completing, the next step is prepared and begins immediately afterward, ensuring that the compaction process runs continuously without idle time. This continuous multi-step compression achieves up to 44% volume reduction while minimizing total processing time through efficient sequential execution.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A method is provided for compacting textile articles for packaging. At least one article is placed in a mold. The article is compressed multiple times to form a rigid bundle, each compression including the steps of subjecting the article to a predetermined pressure for a predetermined period. Between each compression, the pressure is released. Each compression reduces the compacted volume of the rigid bundle.
