Solution Overview

Problem

Existing packaging machines for products like beds and bed headboards experience production stops and reduced efficiency when changing package rolls, as the integrated structure of input, closing, and edge adhesion units requires manual intervention and line halts, complicating operator operations.

Innovation Solution

A modular coating unit with an upper and lower carrier, a welding unit, and a mechanism allowing the coating unit to move between operation and waiting positions, utilizing wheels, rails, rack and pinion gears, and a press arm to facilitate automatic and efficient roll changes without stopping the production line.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the coating unit is integrated with the input unit and passage conveyor, then the packaging machine has a stable and compact structure, but the production line must stop when the package roll needs to be changed

Engineering Contradiction:
Improvestructural stabilityVSAvoidproduction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The coating unit is divided into separate modules: an upper carrier module and a lower carrier module, each capable of independent movement. This segmentation allows one module to be replaced while the other remains in position, enabling continuous production without stopping the entire line.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coating unit is designed with dynamic positioning capability, allowing it to move between an operation position (where it performs coating) and a waiting position (where it can be replaced). This dynamic mobility resolves the contradiction by enabling the system to adapt its configuration based on operational needs.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the coating unit is integrated with the input unit and passage conveyor, then the packaging machine operates as a unified system, but the operator finds it difficult to replace package rolls

Engineering Contradiction:
Improvesystem integrationVSAvoidroll replacement ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

By segmenting the coating unit into separable upper and lower carrier modules, the system maintains overall integration while enabling easy replacement. The modular design allows operators to quickly swap rolls without dismantling the entire coating system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The package roll is extracted as a separate, replaceable component from the integrated coating unit. This extraction allows the roll to be independently removed and replaced without affecting the rest of the system, significantly improving operational ease.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If the coating unit is fixed in position, then the packaging machine has simpler structure, but production stops when package roll needs changing

Engineering Contradiction:
Improvestructural simplicityVSAvoidproduction downtime
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The coating unit is transformed from a fixed structure to a dynamic one that can move between operation and waiting positions. This dynamic capability adds minimal complexity while eliminating production downtime during roll changes, as the replacement can occur in the waiting position without interrupting the coating operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coating unit can be positioned in advance in the waiting position before a roll change is needed. This preliminary positioning allows the replacement operation to be prepared ahead of time, ensuring continuous production flow when the actual roll change occurs.

Inventive Principle:
Principle #10Preliminary action
