Solution Overview

Problem

Existing devices for stabilizing folded packages, such as cigarette packets, are not versatile and struggle to adjust operating parameters like pressure and temperature effectively, leading to inconsistent connections with specific adhesive materials.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If temperature and pressure are maintained constant by the operating unit along the entire path, then the device structure is simple, but the connection quality of package portions deteriorates

Engineering Contradiction:
Improvedevice structureVSAvoidconnection quality
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The heating path is divided into multiple independent heating zones (first heating zone, second heating zone, third heating zone) along the conveyor path. Each zone can independently control temperature and pressure parameters, allowing different portions of the package to receive optimized stabilization treatment according to their specific adhesive requirements, thereby improving connection quality without excessive overall complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different heating zones are assigned different temperature and pressure characteristics tailored to local needs. For example, the first heating zone operates at higher temperature for initial adhesive activation, while subsequent zones use lower temperatures for controlled drying. This localized parameter optimization ensures each area receives exactly what its adhesive material requires, resolving the contradiction between simple structure and high connection quality

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the device is designed to be versatile with adjustable parameters, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improveparameter adjustabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The operating unit incorporates adjustable mechanisms that allow temperature and pressure parameters to be dynamically modified for different adhesive materials and package types. The heating zones can be independently controlled to provide flexible parameter combinations, enabling the device to adapt to various production requirements while maintaining a relatively simple overall structure through modular design

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If multiple heating zones with independent control are implemented, then manufacturing precision improves, but device complexity and cost increase

Engineering Contradiction:
Improveconnection qualityVSAvoiddevice structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The stabilization process is segmented into multiple heating zones along the conveyor path, each with independent temperature and pressure control. This segmentation allows precise control of adhesive drying and setting at different stages, significantly improving connection quality. The modular zone structure manages complexity by breaking down the control system into manageable, independently adjustable units rather than one complex monolithic system

Inventive Principle:
Principle #1Segmentation
