Solution Overview

Problem

Existing conveying apparatuses for folding apparatuses in packaging machines for pourable products are in need of improvement to enhance efficiency and guidance during the advancement of finalized packages.

Innovation Solution

A conveying apparatus with a folding unit and a manipulation assembly that includes retaining pockets and a conveying device, which guides and manipulates semi-finalized packs into finalized packages by folding sealing fins and flaps onto the central main body, using a control device to manage the position of delimiting elements for stable package advancement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a conventional conveyor belt is used to advance finalized packages, then the packages can be transported, but the guidance and stability during advancement are insufficient, allowing rotations to occur

Engineering Contradiction:
Improvepackage stabilityVSAvoidconveying apparatus complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The conveyor belt is segmented into multiple independent conveyor elements (such as individual fingers or segments) that can move relative to each other. This segmentation allows each element to independently guide and stabilize packages, preventing rotations while maintaining overall system simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conveying apparatus introduces additional dimensional control through vertically adjustable conveyor elements or multi-plane conveyor structures. This allows the system to provide guidance not only in the horizontal transport direction but also in vertical and rotational dimensions, stabilizing packages without requiring a completely complex apparatus.

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

2Ease of manufacture

If the conveying apparatus structure is simplified for ease of manufacture, then manufacturing becomes easier, but the guidance capability during package advancement deteriorates

Engineering Contradiction:
Improveconveying apparatus manufacturabilityVSAvoidpackage positioning precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The conveyor elements are designed with multi-functionality, serving both as simple support structures (easy to manufacture) and as precise positioning guides (high manufacturing precision). Each conveyor element can simultaneously provide mechanical support, lateral guidance, and rotational constraint, achieving both ease of manufacture and positioning precision through universal design.

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

Solution Approach 2:

The conveying apparatus uses adjustable parameters such as conveyor element spacing, height, and angle to optimize both manufacturability and positioning precision. By allowing parameter adjustment rather than requiring complex fixed structures, the system achieves high precision package guidance while maintaining manufacturing simplicity through standardized components.

Inventive Principle:
Principle #35Parameter changes
