Solution Overview

Problem

Existing packing body structures suffer damage due to direct contact of fastening bands with packaging edges during stacking and transportation, concentrating stress loads and causing damage to packaging bodies at edge positions.

Innovation Solution

A method involving the use of upper and lower reinforcing sheet materials to wrap the packaging bodies, with fastening bands placed between these sheets to distribute the force and prevent edge damage, while maintaining a groove for forklift insertion and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If fastening bands are placed directly on packaging bodies to secure the stack, then the packaging bodies are firmly fastened and transport stability is improved, but the packaging bodies at edge portions suffer stress concentration and damage

Engineering Contradiction:
Improvetransport stabilityVSAvoidedge damage
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces reinforcing sheet materials as intermediary elements between the fastening bands and the packaging bodies. These sheets are placed at the edge portions of the stacked packaging bodies, allowing the fastening bands to secure the stack firmly while distributing the stress across the reinforcing sheets rather than concentrating it on the packaging body edges, thus preventing damage while maintaining transport stability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If reinforcing materials are added to protect packaging edges, then damage prevention is improved, but the complexity of the packing process increases

Engineering Contradiction:
Improveedge protectionVSAvoidpacking process complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The reinforcing sheet materials are placed on the packaging bodies before the fastening bands are applied. This preliminary placement ensures that the protective sheets are already in position to distribute stress, and the fastening bands can then be simply wrapped around the stack without requiring additional complex mechanisms or steps for edge protection

Inventive Principle:
Principle #10Preliminary action

AI summary

A method of producing a packing body that prevents stacked packaging bodies from becoming damaged at a low cost. The method includes the steps of; stacking a plurality of packaging bodies 10, placing reinforcing sheet materials 13, 14 so as to wrap outer peripheries of side surfaces of the packaging bodies 10 that have been stacked, and fastening the packaging bodies 10 that have been stacked by placing a fastening band 12 from an outer side of the reinforcing sheet materials 13, 14. The step of placing reinforcing sheet materials 13, 14 includes placing the reinforcing sheet materials 13, 14 on the side surfaces of the packaging bodies 10 to protrude an end portion of the reinforcing sheet material 13 from an upper surface of a packaging body 10 in an uppermost layer and to protrude end portion of the reinforcing sheet material 14 from a lower surface of a packaging body 10 in a lowermost layer. The step of fastening the packaging bodies 10 that have been stacked includes bending the end portion of the reinforcing sheet material 13 that protrudes from the upper surface of the packaging body 10 in the uppermost layer and the end portion of the reinforcing sheet material 14 that protrudes from the lower surface of the packaging body 10 in the lowermost layer towards a side of an upper surface of the uppermost layer and towards a side of a lower surface of the lowermost layer, respectively, covering an edge portion of each packaging body 10, and placing the fastening band 12 on the edge portions with the reinforcing sheet materials 13, 14 interposed therebetween.
