Derinding Cutting Device Packaging with Opaque Foldable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic packaging for cutting devices used in derinding and membrane skinning is partially recyclable and transparent, posing a risk of injury during handling due to visibility of the blade, making it difficult to replace blades safely and efficiently.
Innovation Solution
A packaging design using opaque materials like paper or cardboard, with rounded edges on the cutting device and a specific foldable structure that protects the blade, allowing for safe handling and easy orientation, reducing the risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transparent plastic packaging is used, then the user can see the blade path and orientation, but the packaging is less recyclable and poses injury risk
Solution Approach 1:
The patent introduces an intermediary element (transparent window or labeling system) that allows blade orientation information to be communicated to the user without requiring the entire packaging to be transparent. This mediator transmits the necessary visual information while maintaining the protective opacity of the packaging material, thus reducing injury risk while preserving ease of operation.
Solution Approach 2:
Instead of making the packaging transparent to show the blade, the patent uses copying by creating visual representations (labels, diagrams, or transparent windows showing only critical orientation information) that replicate the necessary blade path and orientation data. This allows users to obtain the needed information without exposing them to the actual sharp blade through transparent packaging.
2Reliability
If opaque packaging material is used, then recyclability is improved, but the user cannot see the blade path and orientation
Solution Approach 1:
The packaging is segmented into different functional zones: opaque material for protection and recyclability, and transparent windows or labeled areas for information display. This segmentation allows the packaging to simultaneously achieve recyclability through opaque material and information transmission through localized transparent sections or printed guidance.
Solution Approach 2:
The patent employs color changes and visual contrasts through labeling systems, printed diagrams, or colored transparent windows that highlight blade orientation information on otherwise opaque packaging. This allows critical information to stand out against the opaque background, maintaining both recyclability and information accessibility.
3Object-affected harmful factors
If transparent packaging is used, then injury risk is reduced, but the packaging is less environmentally friendly
Solution Approach 1:
The packaging applies local quality by making only specific localized areas transparent (windows or label regions) rather than the entire packaging. This allows injury risk reduction through visible blade orientation information in critical areas while maintaining recyclability through opaque environmentally friendly materials in the rest of the packaging structure.
