Solution Overview

Problem

Conventional packing members formed from a single sheet material lack effective cushioning without increasing overall thickness, necessitating additional components or complex assembly processes.

Innovation Solution

A packing member design featuring a pair of cushioning portions, including a first cushioning portion in the shape of a plate extending along the second direction and a second cushioning portion in an inverted V-shape above the first, formed by bending a single sheet material, providing enhanced cushioning without increasing thickness or requiring additional components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single sheet material is used to form the packing member, then the device complexity is reduced, but the cushioning efficacy is insufficient

Engineering Contradiction:
Improvecomponent countVSAvoidcushioning efficacy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The cushioning portion is divided into multiple segments (first cushioning portion and second cushioning portion) formed from different regions of the same sheet material. The first cushioning portion is formed by bending the sheet material in a first direction, while the second cushioning portion is formed by bending it in a second direction perpendicular to the first, creating segmented cushioning zones that provide enhanced protection without adding separate components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention utilizes multiple spatial dimensions to create cushioning portions at different heights and positions. The first cushioning portion extends in the first direction while the second cushioning portion extends in the second direction perpendicular to the first, creating a multi-dimensional cushioning structure that provides comprehensive protection from a single sheet material

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

2Reliability

If the overall thickness of the packing member is increased to improve cushioning, then the cushioning efficacy is improved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvecushioning efficacyVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cushioning portions are formed by bending the sheet material at specific locations, creating dynamic, flexible cushioning structures rather than rigid thick walls. The bent portions create localized cushioning zones that provide protection through their geometric configuration rather than through increased material thickness, maintaining structural simplicity

Inventive Principle:
Principle #15Dynamics

3Reliability

If additional components are added to provide cushioning, then the cushioning efficacy is improved, but the assembly process becomes more complex

Engineering Contradiction:
Improvecushioning efficacyVSAvoidassembly process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple cushioning functions are merged into a single integrated structure formed from one sheet material. The first and second cushioning portions are created by bending different regions of the same sheet material, eliminating the need for separate cushioning components and simplifying the assembly process to a single forming operation

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A packing member having a storage space formed by bending a single sheet material has a floor, a pair of side walls, and a pair of cushioning portions. The pair of side walls are formed by being bent upward from circumferential edges of the floor and are arranged opposite each other across the storage space in the first direction. The pair of cushioning portions are arranged opposite each other at opposite ends across the storage space in the second direction orthogonal to the first direction. The cushioning portion has a first cushioning portion formed in a shape of a plate extending along the second direction and a plate-form second cushioning portion arranged above the first cushioning portion at an interval from it, extending along the second direction, and formed in an inverted V-shape as viewed from the second direction.
