Solution Overview

Problem

Existing methods for handling cardboard blanks lack efficiency in forming them into specified formats for further processing, as they do not effectively manage the transition from flat blanks to formed packaging trays.

Innovation Solution

A device with an erecting mechanism featuring engagement elements that can transition from a receiving configuration to a forming configuration, allowing for the simultaneous erection of side regions and adjustment of base regions to change the format of the cardboard blanks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional handling methods are used for cardboard blanks, then the process is simple, but the productivity and efficiency of forming multiple blanks into specified formats is low

Engineering Contradiction:
Improveforming efficiencyVSAvoidhandling device complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single handling device: receiving multiple cardboard blanks, erecting their side regions, and repositioning them into different formats all occur in one integrated device during a single handling operation, eliminating the need for separate devices for each function

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The handling device is designed to perform multiple operations simultaneously: it receives multiple blanks in various configurations, erects side regions of different blanks at the same time, and repositions them into different final formats, making the device universally applicable to multiple processing needs

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

2Loss of time

If cardboard blanks are handled individually, then the handling process is simple, but the time required to form multiple blanks is excessive

Engineering Contradiction:
Improveprocessing timeVSAvoidforming throughput
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

Multiple cardboard blanks are received, erected, and repositioned simultaneously in a single handling operation. The device processes several blanks in parallel rather than sequentially, combining what would traditionally be separate operations into one unified process that occurs at the same time

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device maintains continuous productive action by simultaneously performing receiving, erecting, and repositioning operations on multiple blanks without idle time between operations. All useful actions occur in parallel, maximizing the utilization of the handling device throughout the processing cycle

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If the side regions are erected after positioning, then the positioning is simple, but the overall process efficiency is reduced

Engineering Contradiction:
Improveforming speedVSAvoidcoordination mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The side regions of the cardboard blanks are erected during the handling operation itself, before the blanks are delivered to the next processing station. This preliminary erection action ensures that blanks arrive at subsequent stations already in their final three-dimensional form, eliminating the need for separate erecting operations later

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The erecting operation is merged with the positioning and handling operations. The device simultaneously performs side region erection and format repositioning during the same handling cycle, combining what would traditionally be sequential operations into a single integrated action

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If multiple formats are prepared separately, then each format can be optimized, but the device complexity and space requirements increase

Engineering Contradiction:
Improveformat flexibilityVSAvoidhandling system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handling device incorporates movable and adjustable components that allow it to dynamically reposition cardboard blanks into different formats. The device can adapt its configuration during operation to accommodate multiple final formats, transforming from a static positioning system to a dynamic repositioning system that can handle various arrangements

Inventive Principle:
Principle #15Dynamics
