Solution Overview

Problem

Existing devices for handling stacked layers of goods require time-consuming manual adjustments and product-specific setups when changing products, leading to inefficiencies in adapting to new product formats.

Innovation Solution

A device and method that includes a sliding frame for moving the top layer and a fixing device with adjustable elements, guided by sensors for automatic positioning, to securely transfer layers while maintaining the integrity of intermediate layers, allowing rapid adaptation to different product configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual adjustment of holding devices is performed for each product change, then the holding devices can be positioned accurately for the specific container arrangement, but the adjustment process becomes time-consuming and disrupts production

Engineering Contradiction:
Improvepositioning accuracy of holding devicesVSAvoidadjustment time during product changes
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary detection of container positions and intermediate layer locations using sensors before the actual holding device adjustment. This advance information gathering allows the control unit to pre-calculate optimal holding positions, eliminating the need for time-consuming manual measurement and positioning during production changes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The holding devices are equipped with automatic positioning capability that uses sensor data to self-adjust their locations. The control unit automatically moves the holding devices to the correct positions based on detected container arrangements, making the system self-sufficient and eliminating dependency on manual intervention for repositioning.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If holding devices are manually repositioned for different container sizes and shapes, then the device can adapt to new product formats, but production interruptions occur during the repositioning process

Engineering Contradiction:
Improveadaptability to different container formatsVSAvoidproduction continuity during product changes
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system detects container positions and intermediate layer locations in advance using sensors, allowing the control unit to pre-plan and execute holding device repositioning operations before the next production batch begins. This preliminary action enables seamless transitions between different container formats without stopping production.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The holding devices are designed with dynamic positioning capability, allowing them to move automatically between different locations based on detected product configurations. This dynamic adjustment system can quickly adapt to various container sizes and shapes while maintaining continuous operation, as the devices can be repositioned during production cycles rather than requiring separate setup time.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the intermediate layer is not securely fixed during layer removal, then the device structure remains simple, but the intermediate layer may be pulled along with the container layer, disrupting further processing

Engineering Contradiction:
Improvesimplicity of device structureVSAvoidstability of intermediate layer positioning
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The intermediate layer fixing system uses automatic detection of layer positions and intermediate layer locations to self-position holding devices. The control unit automatically adjusts holding device positions based on sensor feedback, making the system self-regulating and eliminating the need for complex manual adjustment mechanisms while ensuring reliable intermediate layer stabilization during container layer removal.

Inventive Principle:
Principle #25Self-service
