Solution Overview

Problem

Existing packaging systems for hose-shaped foil are inefficient and complex, particularly in terms of packaging time and object handling, as they primarily operate vertically and lack optimized mechanisms for handling and transporting objects between conveyors.

Innovation Solution

A system that enables horizontal wrapping of objects using hose-shaped stretch foil, featuring a control unit that directs a packaging frame with gripping arms equipped with activated rollers between conveyors, allowing for efficient object handling and transportation, and an optional laterally movable packaging frame for simultaneous foil gathering and packaging, along with a cone-shaped device for easy foil opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If vertical wrapping is used with traditional hood packaging installations, then the packaging process is established, but the production cycle efficiency is reduced and complexity increases

Engineering Contradiction:
Improveproduction cycle efficiencyVSAvoidpackaging system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent inverts the traditional vertical wrapping approach by implementing horizontal wrapping. The packaging frame moves horizontally between conveyors, and the foil is wrapped around objects in a horizontal plane rather than vertically. This inversion simplifies the overall system architecture and accelerates the packaging cycle by eliminating complex vertical movement mechanisms.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transitions from vertical (one-dimensional) wrapping to horizontal (two-dimensional) wrapping by positioning the packaging frame to move laterally between conveyors. This dimensional change allows for more efficient space utilization and reduces the complexity of vertical positioning mechanisms while maintaining effective packaging functionality.

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

2Ease of operation

If traditional vertical packaging frames are used, then object wrapping is achieved, but object handling and transportation between conveyors becomes inefficient

Engineering Contradiction:
Improveobject handling efficiencyVSAvoidpackaging time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The packaging frame is designed as a dynamic structure that can move horizontally between conveyors and adjust its position relative to objects on the conveyor belt. The gripping arms are equipped with activated rollers that can dynamically engage and disengage from the foil, enabling efficient object handling and reducing packaging time through rapid positioning and wrapping actions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The activated rollers on the gripping arms serve as intermediaries between the packaging frame and the hose-shaped stretch foil. These rollers efficiently transfer the wrapping force to the foil while facilitating smooth object handling, reducing friction and packaging time through optimized contact mechanics.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If hose-shaped stretch foil is used for wrapping, then object protection and stability are provided, but the foil gathering and opening mechanisms become complex

Engineering Contradiction:
Improveobject protectionVSAvoidfoil gathering mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The packaging frame is divided into multiple gripping arms, each equipped with its own activated rollers for independent foil gathering and manipulation. This segmentation allows each gripping arm to handle specific portions of the hose-shaped stretch foil independently, simplifying the overall gathering mechanism while maintaining reliable object protection through coordinated action of multiple segments.

Inventive Principle:
Principle #1Segmentation
