Solution Overview

Problem

Existing palletizing devices require a significant time and effort to move filled sacks from the feed position to the sliding position due to a large feed distance, which increases the overall duration of the palletizing process.

Innovation Solution

The palletizing device design includes a feed belt that protrudes into the frame of the pushing device, reducing the feed distance between the feed and shifting positions, allowing the feed position to be completely within the frame, thereby minimizing the movement path and time required for this transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the feed belt is arranged laterally next to the sliding surface, then the feeding structure is simple, but the feed distance becomes large and palletizing time increases

Engineering Contradiction:
Improvefeeding structureVSAvoidpalletizing time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The feed belt is extended in the longitudinal direction to protrude into the frame of the pushing device, changing the spatial arrangement from a purely lateral configuration to one that utilizes the longitudinal dimension. This dimensional extension reduces the feed distance without adding complex lateral structures.

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

Solution Approach 2:

The feed belt performs preliminary conveying action by delivering filled sacks directly to a position within the pushing device frame, pre-positioning the sacks closer to the sliding surface before the pushing operation begins. This preliminary positioning reduces the subsequent movement required.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If the feed distance is reduced by protruding the feed belt into the pushing device frame, then the palletizing time is reduced, but the device complexity increases

Engineering Contradiction:
Improvepalletizing timeVSAvoidfeed belt arrangement
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The feed belt serves multiple functions: it conveys filled sacks from the feeding device and simultaneously positions them within the pushing device frame. This multi-functionality achieves time reduction without requiring separate positioning mechanisms, thereby limiting complexity increase.

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

Solution Approach 2:

The feed belt is integrated with the pushing device frame structure, merging the conveying function with the positioning function. This integration achieves the dual goal of reducing feed distance and minimizing additional structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Length of moving object

If the feed belt protrudes into the frame of the pushing device, then the movement path is minimized, but the structural complexity of the frame increases

Engineering Contradiction:
Improvemovement pathVSAvoidframe structure
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The frame structure is segmented to accommodate the protruding feed belt, with the frame divided into regions that support the belt extension. This segmentation allows the feed belt to protrude without requiring complete frame redesign, limiting structural complexity increase.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The feed belt is nested within the frame structure in such a way that it protrudes into the frame space without requiring external support structures. The belt is accommodated within the existing frame geometry, minimizing additional structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)
