Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional labeling machines experience adhesive quality loss and roller contamination due to continuous sliding of adhesive-facing labels on cutting rollers, leading to operational inefficiencies and jamming.

Innovation Solution

A combined cutting/transfer roller with non-stick treatment and suction capability, where labels are cut and transferred without direct adhesive contact, preventing adhesive deterioration and contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If labels with adhesive face rest on the cutting roller for separation, then label cutting and transfer can be achieved, but the adhesive quality deteriorates and the roller surface becomes contaminated

Engineering Contradiction:

Improvelabel application efficiencyVSAvoidadhesive quality integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces an intermediary solution by inverting the label orientation so that the non-adhesive back surface contacts the cutting roller instead of the adhesive face. This mediates between the need for label cutting/transfer and the need to preserve adhesive quality, eliminating direct contact between adhesive and roller while maintaining the label application process

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies inversion by reversing the conventional label orientation on the cutting roller. Instead of the adhesive face contacting the roller (conventional method), the label is positioned with its back surface on the roller and adhesive face outward. This inverted approach resolves the contradiction by preventing adhesive contamination while preserving the cutting and transfer functions

Inventive Principle:

Principle #13The other way round (Inversion)

2Object-affected harmful factors

If the cutting roller surface is provided with non-stick treatment, then adhesive contamination is reduced, but operational jammings still occur and adhesive quality loss continues

Engineering Contradiction:

Improveroller contaminationVSAvoidoperational smoothness

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent converts the potential harm of adhesive contact into a benefit by systematically inverting label orientation. This ensures the non-adhesive back surface contacts the roller, transforming what would be a harmful interaction into a beneficial one where the roller surface (even with non-stick treatment) interacts only with the label back, eliminating contamination and operational issues

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The inversion principle directly addresses this contradiction by reversing the contact surface. The label back surface (non-adhesive) contacts the roller instead of the adhesive face, converting the harmful adhesive-roller interaction into a harmless non-adhesive-roller interaction, thereby eliminating both contamination and jammings

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If separate cutting roller and transfer roller are used, then label transfer can be achieved, but the machine structure becomes complex

Engineering Contradiction:

Improvelabel transfer capabilityVSAvoidmachine structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the cutting roller and transfer roller into a single integrated component. The inverted label orientation enables this consolidation because the label back surface contacts the roller for cutting, while the adhesive face remains outward for immediate transfer to the bottle, eliminating the need for a separate transfer roller while maintaining full functionality

Inventive Principle:

Principle #5Merging (Combining)
