Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Stickers made of paper or resin used in packaging systems are not durable and can easily peel off, leading to hygiene issues and detection challenges, especially with small pieces adhering to containers, which are difficult to detect using metal detectors.

Innovation Solution

Implementing information display members with metal portions that display information without shaving the metal, using treatments like hot rolling, cold rolling, and blasting, and illuminating with specific light wavelengths to enhance visibility and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If stickers made of paper or resin are used, then various processing such as printing and surface processing can be easily applied, but the stickers are not durable and may easily peel off from the packaging system

Engineering Contradiction:

Improveease of processingVSAvoiddurability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent changes the material parameter from paper/resin to metal, fundamentally altering the durability characteristics while maintaining manufacturability through metal-specific processing methods such as printing, anodizing, and embossing

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The information display member combines metal base material with various surface treatments and coatings to achieve both durability and ease of processing, creating a composite structure that leverages the advantages of different materials

Inventive Principle:

Principle #40Composite materials

2Productivity

If a sticker piece peels off and adheres to a container, then the container may be sent to subsequent stages, but small sticker pieces are difficult to detect through visual inspection or metal detectors

Engineering Contradiction:

Improvepackaging throughputVSAvoiddetection difficulty

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent employs chromatic color display on the metal surface to create high visual contrast, making any detached pieces easily detectable through visual inspection while maintaining the metal's inherent detectability by metal detectors

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The information display member creates a detectable signal (through color, shape, or magnetic properties) that copies the detectability characteristics needed for quality control, ensuring that any detached pieces can be identified as anomalies

Inventive Principle:

Principle #26Copying

3Stability of the object's composition

If information is displayed on a metal portion by shaving the metal, then information can be permanently marked, but the metal portion becomes thinner and more susceptible to damage

Engineering Contradiction:

Improveinformation permanenceVSAvoidmetal thickness

Core Design Contradiction:

Stability of the object's compositionVSStrength

Solution Approach 1:

The patent applies local quality changes through surface treatments such as anodizing, embossing, or laser marking that modify only the surface layer of the metal to display information, leaving the bulk metal thickness and strength intact

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent replaces the mechanical shaving process with alternative information display methods such as surface coating, anodizing, or laser marking, which achieve permanent information display without removing metal material

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
