Solution Overview

Problem

Conventional packaging bodies for wire coils are inefficient in maximizing the number of coils loaded in a container while ensuring protection against collapse and scratching, due to their design which limits the arrangement and stability of the coils during transport.

Innovation Solution

A packaging body design that holds wire coils sideways with a horizontal axis, utilizing base beams, cross beams, a coil holding stand with a recessed section and corrugated engagement sections, and roll cushions to securely position and restrain the coils within the container, allowing for efficient stacking and movement restriction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a regular octagonal abutment member is used to surround the wire coil, then the wire coil is protected from collapse, but the outer shape becomes larger and fewer wire coils can be loaded in a container

Engineering Contradiction:
Improveprotection against collapseVSAvoidouter shape size
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The packaging body is divided into multiple functional components: base beams for support, cross beams for structural integrity, and a coil holding stand with recessed sections for precise coil positioning. This segmentation allows each component to perform its specific function efficiently without requiring an oversized outer structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the orientation of the wire coil from vertical axis to horizontal axis, and positions it sideways in the container. This dimensional change allows more efficient space utilization and enables tighter packing arrangements that reduce the overall outer shape footprint

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If regular octagonal abutment members are arrayed in a staggered pattern, then positioning and movement restriction is achieved, but gaps form between packaging bodies reducing loadable quantity

Engineering Contradiction:
Improvepositioning and movement restrictionVSAvoidnumber of wire coils loadable
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The packaging body uses asymmetric base beam configurations and directional corrugated engagement sections that interface with adjacent packaging bodies in a interlocking manner. This asymmetric design eliminates gaps between units and enables tighter, more efficient array arrangements in the container

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The base beams of adjacent packaging bodies are connected through corrugated engagement sections, merging the structural units into a unified stable array. This connection eliminates movement restrictions and gaps, allowing maximum utilization of container space

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the wire coil is held vertically on a pallet, then the conventional packaging structure is simple, but the wire coil is more susceptible to collapse during vessel transport

Engineering Contradiction:
Improvepackaging structure simplicityVSAvoidresistance to collapse
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The coil holding stand includes pre-formed recessed sections that are designed to accommodate the wire coil in a horizontal sideways position before transport. This preliminary positioning action ensures the coil is optimally supported and restrained against collapse from the outset, without requiring complex additional support structures during transit

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided is a packaging body 1 for a wire coil 6 which holds the wire coil 6 sideways, a plurality of the packaging bodies 1 being to be loaded in a single shipping container 2. The packaging body 1 comprises: a plurality of base beams 15 disposed on a container floor surface 4 and extending in one direction from a door of the shipping container 2 toward its back; a cross beam 33 extending in the width direction of the shipping container 2 and coupling the plurality of base beams 15; and a block-shaped coil holding stand 19 provided on the cross beam 33 and including a recessed section 21 in which to accommodate the wire coil 6 sideways with the axial direction of the cylinder oriented in the width direction of the shipping container 2, the coil holding stand 19 being a stand to which to lash the wire coil 6. The coil holding stand 19 includes a corrugated engagement section 23 on its front surface and back surface as viewed from the door 12 of the shipping container 2 toward its back, the wave direction of the corrugated engagement section 23 being oriented in the width direction of the shipping container 2 in plan view. The corrugated engagement section 23 engages a corrugated engagement section 23 of another packaging body 1. In this way, it is possible to provide a packaging body capable of increasing the number of wire coils loadable in a container as compared to the conventional art without impairing the function of protecting wire coils.
