Solution Overview

Problem

The operating speed of stamp application apparatuses for containers is limited by the time required for hot glue to dry, leading to instability in the fixing of folded stamp portions, which can detach if the glue has not reached sufficient drying, necessitating slower operation to ensure adhesion.

Innovation Solution

Incorporating a pneumatic system that uses compressed air to press the folded stamp portion against the container, combined with a folding unit that accompanies the container during movement, to ensure stable fixation and accelerate glue drying, thereby increasing production capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the folding unit operates at high speed, then productivity increases, but the stamp portion may detach due to insufficient glue drying time

Engineering Contradiction:
Improveproduction capacityVSAvoidfixing stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The folding member applies pressure to the stamp portion before the glue has fully dried, pre-compressing the folded portion against the container surface. This preliminary action ensures immediate adhesion while the glue cures, allowing high-speed operation without detachment

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The folding member is designed to move dynamically with the container during transport, maintaining continuous contact and pressure on the stamp portion throughout the drying process. This dynamic adaptation ensures consistent fixation stability regardless of operational speed variations

Inventive Principle:
Principle #15Dynamics

2Reliability

If the folding member accompanies the container during movement, then fixation stability is maintained, but operating speed decreases

Engineering Contradiction:
Improvefixing stabilityVSAvoidoperating speed
Core Design Contradiction:
ReliabilityVSSpeed

Solution Approach 1:

The folding member maintains continuous pressure on the stamp portion throughout the entire transport cycle, from folding to final fixation. This uninterrupted action ensures the glue dries properly while the stamp remains securely pressed against the container, enabling faster operation without compromising fixation quality

Inventive Principle:
Principle #20Continuity of useful action
