Edge Protection Tool with Material Weakening Zone

Solution Overview

Problem

Existing edge protection devices with material weakening zones suffer from instability and pre-deformation issues during transport and handling, leading to problems when conveyed from strapping device magazines.

Innovation Solution

A device with a tool, such as a rotating roller or cylinder, introduces a material weakening zone into the edge protection just before it is applied to the package, ensuring stability throughout the production, distribution, and handling chain, and optionally using a rigid tool to create a weakening zone by pressing into the edge protection material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a material weakening zone is introduced into the edge protection means during production, then controlled deformation during strapping is improved, but stability during transport and handling deteriorates

Engineering Contradiction:

Improvecontrolled deformationVSAvoidstability during transport

Core Design Contradiction:

Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

The material weakening zone is introduced only shortly before the edge protection means is arranged on the package, not during production. This timing ensures the edge protection maintains full stability during transport and handling, while still achieving controlled deformation when needed for strapping.

Inventive Principle:

Principle #10Preliminary action
