Solution Overview

Problem

Existing methods for covering paperboard boxes with hot adhesive require complex and costly management, including a preparatory phase and precise viscosity control, limiting flexibility and productivity, and lack fully automated solutions for industrial production using cold adhesive applications.

Innovation Solution

A multi-station equipment using a carousel with peeling devices and suction plates applies cold-sticker sheet portions to paperboard boxes, eliminating the need for hot adhesive management and enabling automatic operation for high productivity and simplicity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If hot adhesive covering is used, then the covering process can be automated, but the device complexity and management cost increase due to adhesive distribution systems and viscosity control requirements

Engineering Contradiction:

Improveautomation of covering processVSAvoidcomplexity of adhesive management system

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the hot adhesive distribution system from the covering process. Instead of using a complex adhesive management system with heating and viscosity control, the invention uses pre-prepared self-adhesive sticker sheet portions that are applied cold, thereby removing the troublesome adhesive distribution apparatus while maintaining automated covering capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The adhesive function is performed in advance by pre-coating the sticker sheet portions with adhesive and allowing them to set. This preliminary action eliminates the need for on-demand adhesive heating and distribution, simplifying the covering device while maintaining automation

Inventive Principle:

Principle #10Preliminary action

2Productivity

If hot adhesive covering is used, then continuous production is possible, but the loss of time increases due to preparatory warm-up phase and viscosity maintenance

Engineering Contradiction:

Improvecontinuous production capabilityVSAvoidwarm-up and viscosity control time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The sticker sheet portions are pre-prepared with adhesive coating before production. This eliminates the need for a warm-up phase to activate the adhesive, allowing immediate start of production and eliminating time spent on viscosity maintenance, thereby reducing loss of time while maintaining continuous production capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses disposable self-adhesive sticker sheet portions that are pre-prepared and applied as needed. This eliminates the need for maintaining a continuous supply of hot adhesive, reducing the time required for adhesive system preparation and maintenance while enabling continuous production

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Device complexity

If manual cold sticker application is used, then the device complexity is reduced, but the productivity decreases and the process remains artisan rather than industrial

Engineering Contradiction:

Improvesimplicity of equipmentVSAvoidproduction volume

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The sticker sheet portions are self-adhesive, meaning they carry their own adhesive coating and require no additional glue application equipment. This self-service characteristic allows simple handling and application mechanisms to achieve high productivity, transforming the artisan process into an industrial one without complex equipment

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical adhesive distribution systems with a simpler system based on pre-adhered sticker sheets. The application mechanism only needs to position and press the pre-prepared sticker portions, eliminating the need for complex glue pumps, heating elements, and viscosity control systems, thereby achieving high productivity with simplified equipment

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
