Solution Overview

Problem

Existing edge protection mounting devices for sheet coils are bulky and time-consuming, particularly when applying material to both inner and outer edges.

Innovation Solution

A compact edge protection mounting device with sideways-mounted arm arrangements and guides that allow for quick application of edge protection material to both inner and outer edges of sheet coils, using a system with two edge protection mounting devices and a sheet coil rotating arrangement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If traditional edge protection mounting devices are used, then edge protection material can be applied to sheet coils, but the devices are bulky and the system occupies excessive space

Engineering Contradiction:
Improvesystem footprintVSAvoidedge protection application capability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The mounting arm arrangement is repositioned from a vertical configuration (above/below the coil) to a horizontal configuration (at the side of the coil). The material guide directs edge protection material sideways onto the coil edges, enabling the system to operate from the lateral dimension rather than requiring vertical space, thus reducing overall system footprint while maintaining full edge protection functionality

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

2Productivity

If traditional edge protection mounting devices are used, then edge protection can be applied, but the process is time-consuming

Engineering Contradiction:
Improveedge protection application speedVSAvoidwrapping cycle time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The edge protection mounting device is integrated with the sheet coil wrapping system, combining two previously separate operations (edge protection application and coil wrapping) into a single coordinated process. The mounting arm and material guide work simultaneously with the wrapping mechanism, allowing edge protection material to be applied and wrapped in one continuous motion, thereby eliminating sequential delays and accelerating the overall process

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If traditional edge protection mounting devices are used, then both inner and outer edges can be protected, but the device complexity increases

Engineering Contradiction:
Improveinner and outer edge protection capabilityVSAvoidmounting device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting arm arrangement with the material guide is designed as a universal device that can apply edge protection material to both inner and outer coil edges using the same basic mechanism. By positioning the device at the side of the coil and utilizing the sideways material guidance, a single configuration handles multiple protection scenarios without requiring separate complex subsystems for inner and outer edge treatment

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An edge protection mounting device for use in a system for sheet coil packaging is provided. The edge protection mounting device includes a mounting arm arrangement including at least one edge protection material guide, configured to feed out and guide edge protection material into correct positions along at least one edge of a sheet coil. The at least one edge protection material guide is shaped to guide the edge protection material so that it is displaced sideways from the mounting arm arrangement. Further, a system for sheet coil packaging is provided, including a sheet coil wrapping arrangement, a sheet coil rotating arrangement, and two edge protection mounting devices. A method of sheet coil packaging is also provided, including wrapping a sheet coil using a sheet coil wrapping arrangement, and feeding out edge protection material along edges of the sheet coil using two edge protection mounting devices.
