Solution Overview

Problem

The large size of corrugated cardboard boxes used for shipping stacked bundles of paper results in high transportation costs and significant storage space requirements, leading to increased inventory loads and storage needs.

Innovation Solution

The method involves compressing stacked bundles of paper into vacuum-packed bodies, which are then packed in a storing body, such as a kraft paper bag, allowing for more efficient use of space and reducing transportation and storage costs by using a packaging member that temporarily maintains a vacuum state, ensuring the packed bodies remain firm and densely packed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stacked bundles of paper are packed in large corrugated cardboard boxes without compression, then the bundles are easily protected and handled, but transportation cost increases and storage space requirements increase

Engineering Contradiction:
Improveprotection and handling easeVSAvoidstorage space
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent applies vacuum compression to change the physical state of the bundled papers, reducing their volume by removing air from the packaging. This parameter change (from atmospheric pressure to vacuum state) allows significantly more bundles to be packed into the same storage space while maintaining protection through the vacuum-sealed packaging member.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent nests multiple vacuum-compressed bundles within a single storing body (kraft paper bag). By compressing individual bundles first and then nesting them together in the final packaging, the system achieves dense packing that reduces overall storage volume while maintaining the integrity of each bundled unit.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Volume of stationary object

If stacked bundles of paper are compressed into vacuum packaged bodies, then storage space is reduced and more bundles fit in the storing body, but the packaging member must be temporarily maintained in vacuum state

Engineering Contradiction:
Improvestorage spaceVSAvoidpackaging member requirements
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The patent employs a packaging member (kraft paper bag) that is simple, inexpensive, and does not require complex vacuum maintenance systems. The bag is sealed to create temporary vacuum compression during transport and storage, then easily opened at the destination without specialized equipment, making the system economically viable despite the vacuum requirement.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The vacuum compression is applied in advance during the packaging process, before the bundles are transported or stored. This preliminary action compresses the bundles into their final compact state, eliminating the need for ongoing vacuum maintenance during storage and simplifying the logistics of handling the packed bundles.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If corrugated cardboard boxes are used for packing, then the bundles are well protected, but transportation cost increases and inventory load increases

Engineering Contradiction:
ImproveprotectionVSAvoidtransportation cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent transitions from bulk unpacked bundles to vacuum-compressed bundles, changing the density parameter of the packaged material. This compression increases the quantity of bundles that can be transported per unit volume, directly reducing transportation costs and inventory requirements while maintaining protection through the sealed packaging.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent combines multiple bundles into a single vacuum-sealed storing body, merging what would traditionally require multiple separate corrugated boxes into one consolidated package. This consolidation reduces the total number of packages to be handled and transported, lowering both transportation costs and inventory management complexity.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This method reduces transportation costs and storage space requirements by allowing more bundles to be packed in a smaller area, with the temporary vacuum packaging ensuring the packed bundles remain firm and stable during handling and storage, and the use of kraft paper bags provides a cost-effective and easily unpackable solution.

Implementation Method 1

a compression process of packaging a plurality of the stacked bundles made of paper in a packaging member and removing air from the packaging member, thereby producing a vacuum packaged body in which the stacked bundles made of paper are vacuum-packaged

AI summary

A method for packing stacked bundles made of paper that can reduce transportation cost of the stacked bundles made of paper and can reduce the storage space in a warehouse, etc., is provided. An operator firstly arranges three bundles of the paper towels 10 laterally and put the three bundles of the paper towels 10 in the packaging member 20. As the packaging member 20, a commercially available bag made of polyethylene is used. Next, by using a vacuum apparatus, air in the packaging member 20 is sucked until a thickness of the bundles of the paper towels 10 reduces about a half or so. According to this procedure, a vacuum packaged body 100 in which three bundles of the paper towels 10 are vacuum-packaged can be obtained. Next, a plurality of the vacuum packaged bodies 100 are packed in a corrugated cardboard box 200. Since a commercially available bag is used as the packaging member 20, the vacuum packaged body 100 is gradually swelling when several hours pass since vacuum-packaging. According to this procedure, the bundles of the paper towels 10 are in the state of being densely packed in the corrugated cardboard box 200. Finally, the operator seals the corrugated cardboard box 200.
