Cushioning Material with Separated Sections to Prevent Impact Peeling

Solution Overview

Problem

Conventional corrugated cardboard cushions experience peeling at the boundary between the flat surface section and the side surface section when impacted, leading to displacement and loss of cushioning function.

Innovation Solution

The cushioning material features a flat surface section and a side surface section connected by a connecting section in a separated state, with the gluing section positioned away from the product's edge contact point to prevent peeling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the flat surface section and side surface section are fixed together by a gluing section at the boundary, then the cushioning material maintains structural integrity, but peeling occurs at the boundary when impact is applied

Engineering Contradiction:

Improvestructural integrityVSAvoidpeeling resistance

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The cushioning material is divided into a flat surface section and a side surface section that are connected through a connecting section rather than being rigidly fixed together. This segmentation allows each section to move independently during impact, preventing peeling while maintaining overall structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting section is designed to allow relative movement between the flat surface section and side surface section. This dynamic connection enables the sections to adapt to impact forces without peeling, transforming a static rigid connection into a dynamic flexible one.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If the gluing section is positioned at the boundary between flat surface section and side surface section, then the material is easy to manufacture, but the cushioning function is lost due to displacement

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidcushioning function

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The cushioning material is divided into a flat surface section and a side surface section that are connected through a connecting section rather than being rigidly fixed together. This segmentation allows each section to move independently during impact, preventing peeling while maintaining overall structural integrity.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If the flat surface section and side surface section are rigidly connected, then the structure is stable, but the material cannot accommodate impact forces and peeling occurs

Engineering Contradiction:

Improvestructural stabilityVSAvoidimpact resistance

Core Design Contradiction:

Stability of the object's compositionVSStrength

Solution Approach 1:

The cushioning material is divided into a flat surface section and a side surface section that are connected through a connecting section rather than being rigidly fixed together. This segmentation allows each section to move independently during impact, preventing peeling while maintaining overall structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting section changes the rigidity parameter of the connection between sections, transitioning from a rigid fixed connection to a flexible movable connection. This parameter change allows the structure to accommodate impact forces while maintaining stability during normal use.

AI summary

A cushioning material includes: a flat surface section flatly placed on the product; a side surface section provided on a side surface of the flat surface section; and a connecting section that connects the flat surface section and the side surface section in a separated state.
