Metal Information Display Attachment for Hygienic Packaging Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stickers made of paper or resin used on packaging systems are prone to peeling off, which can adhere to containers and go undetected, posing hygiene and detection challenges, especially with metal detectors.
Innovation Solution
Use information display members with metal portions that display information without shaving the metal, made of durable materials like stainless steel or aluminum, and treated with processes such as hot rolling and alumite treatment, with lighting units to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If stickers made of paper or resin are used on packaging systems, then they are inexpensive and can easily receive various processing such as printing and surface processing, but they are not durable and may relatively easily peel off from the packaging systems
Solution Approach 1:
The patent changes the material parameter from paper/resin to metal, fundamentally altering the durability and detection properties. This parameter change resolves the contradiction by providing a material that is both durable and detectable, though it requires different manufacturing processes suitable for metal materials.
Solution Approach 2:
The patent employs composite material construction with a metal base layer providing durability and a colored coating layer providing information display functionality. This composite approach maintains ease of information presentation while achieving the durability of metal materials.
2Loss of information
If stickers are used on packaging systems, then information can be displayed, but they may unintentionally adhere to containers undergoing packaging processing and be difficult to detect
Solution Approach 1:
The patent changes the material parameter from non-metallic (paper/resin) to metallic, which fundamentally alters the detectability property. Metal materials can be detected by metal detectors, resolving the detection difficulty while maintaining information display capabilities through surface coloring or marking.
Solution Approach 2:
The patent applies color changes through colored coatings or markings on the metal surface to maintain information display visibility. This allows the metal portion to be both detectable by metal detectors and visually informative for operators.
3Stability of the object's composition
If information is displayed on metal portions by shaving the metal, then information can be permanently marked, but the metal surface is damaged and hygiene is compromised
Solution Approach 1:
The patent changes the marking method from mechanical removal (shaving) to surface application (coating or anodization). This parameter change in the marking process preserves the metal surface integrity and hygiene properties while achieving permanent or semi-permanent information marking.
Solution Approach 2:
The patent uses a composite structure with a metal base layer and a colored coating layer for information display. This allows permanent marking through the coating without damaging the underlying metal surface, maintaining both hygiene and information stability.
