Solution Overview

Problem

Existing packaging devices require manual and time-consuming adjustments to change between different dimensioned packaging blanks, leading to potential errors and disruptions in the packaging process.

Innovation Solution

A packaging device with a horizontal conveyor and a feed system that allows for easy switching between first and second conveyor devices, which are arranged on a common linear guide and coupled to a common drive shaft, enabling automatic adjustment of spacing and positioning for different flat packaging blanks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual adjustment of carrier spacing is used to change between different packaging blanks, then the device can be adapted to different packaging dimensions, but the changeover process becomes time-consuming and requires stopping the entire device

Engineering Contradiction:
Improveadaptability to different packaging blanksVSAvoidchangeover time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamic adjustability of carrier spacing through motorized actuators that can automatically change the distance between carriers based on the packaging blank being used. This allows the system to adapt to different packaging dimensions without manual intervention, resolving the contradiction by making the spacing adjustment dynamic rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit automatically manages the carrier spacing adjustment based on input parameters about the packaging blank. The system self-regulates the actuator positions without requiring operator intervention, enabling quick changeovers while maintaining adaptability to different packaging types.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If manual adjustment of carrier spacing is performed, then different packaging blanks can be accommodated, but the risk of incorrect setting increases leading to handling problems

Engineering Contradiction:
Improveadaptability to different packaging blanksVSAvoidsetting accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The control unit receives input parameters about the packaging blank and automatically calculates and sets the appropriate carrier spacing. This feedback mechanism ensures accurate positioning by eliminating manual measurement and adjustment errors, thereby improving reliability while maintaining adaptability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automated control system that uses sensors and actuators to precisely position carriers. This substitution of manual operation with automated control eliminates human error in spacing adjustment, ensuring consistent and accurate settings for different packaging blanks.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the device is stopped for extended periods during changeover, then manual adjustment can be performed, but productivity is reduced

Engineering Contradiction:
Improveadjustment simplicityVSAvoidpackaging throughput
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The dynamic actuator system enables carrier spacing changes to be performed quickly during operation or with minimal stopping. This dynamic adjustment capability maintains ease of operation while significantly reducing the time the device needs to be stopped, thereby preserving productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit pre-calculates and pre-positions the carriers based on the upcoming packaging blank specifications. This preliminary action allows the system to be ready for the next packaging type with minimal interruption, maintaining both ease of operation and high productivity.

Inventive Principle:
Principle #10Preliminary action
