Solution Overview

Problem

Existing horizontal-type automatic packaging machines struggle to adapt to pouches of different formats, requiring different operations and product fillings, without needing to change machine configurations.

Innovation Solution

A packaging machine with a track and carriage assemblies that can grip pouches, processing modules with configurable tools, and control units that can be easily added, removed, or reconfigured to handle different pouch formats and operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the packaging machine uses fixed processing units for specific pouch formats, then the machine can perform precise operations for that format, but the machine cannot adapt to different pouch formats without reconfiguration

Engineering Contradiction:
Improveadaptability to different pouch formatsVSAvoidmachine configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a movable processing unit that can be repositioned along the conveyor track to different stations. This dynamic positioning capability allows the same processing unit to adapt to different pouch formats by changing its location along the track, rather than requiring fixed dedicated units for each format. The processing unit maintains operational precision while gaining versatility through its ability to move to appropriate positions for different pouch types.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a universal processing unit that can handle multiple pouch formats through repositioning along the conveyor track. Instead of having separate specialized units for each pouch format, a single multi-functional processing unit serves all formats by being moved to different stations, thereby reducing overall system complexity while maintaining adaptability.

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

2Adaptability or versatility

If the packaging machine is reconfigured for each pouch format, then it can handle different formats precisely, but the production time and commissioning complexity increase

Engineering Contradiction:
Improvehandling different pouch formatsVSAvoidproduction time and commissioning time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The movable processing unit enables rapid reconfiguration by simply changing the position of the unit along the conveyor track rather than requiring physical reassembly or complex setup changes. This dynamic repositioning significantly reduces the time needed to switch between different pouch formats during production or commissioning phases.

Inventive Principle:
Principle #15Dynamics

3Productivity

If multiple fixed processing units are installed for different formats, then all formats can be handled simultaneously, but the machine becomes more complex and less flexible

Engineering Contradiction:
Improvesimultaneous handling of different formatsVSAvoidnumber of processing units
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Instead of installing multiple fixed processing units to handle different formats simultaneously, the patent uses a single movable processing unit that can be positioned at different stations along the conveyor track. This dynamic approach maintains productivity by allowing the unit to service different pouch formats at appropriate locations while significantly reducing the total number of processing units required.

Inventive Principle:
Principle #15Dynamics

AI summary

A packaging machine (100) comprising a track with a number of carriage assemblies moveable along the track and able to hold in a suspended fashion a flexible pouch and to convey them along at least a section of the track; a series of processing modules (6a, 6b) moveably engaged with a common supporting rail (12), the processing modules having configurable tools able to perform an operation on the conveyed pouches; and a corresponding series of control units (5a, 5b), each control unit to control the configurable tools of a processing module or the configurable tools of a set of functionally-related processing modules, the control units being moveably engageable in a static frame (101) to which the supporting rail (12) of the processing modules (6a, 6b) is also solidly joined to.
