Welding Wire Container Cover Structure for Strength and Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage containers for welding wire require separate head cap members, are vulnerable to external impacts, and have complex recycling processes, leading to increased production costs and environmental concerns.
Innovation Solution
A storage container design that includes a cover with a perforated portion for easy recycling, is resistant to external impacts and buckling loads, and does not require a separate head cap member, utilizing a paper material for the container and incorporating strength reinforcement and shock absorption parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional storage container uses metal members and separate head cap members for strength, then the container has sufficient strength, but the recycling process becomes complex and production costs increase
Solution Approach 1:
The patent merges the head cap member and the container body into a single integrated structure. The cover includes an integrated reinforcement structure that combines the sealing flange and reinforcement functions in one piece, eliminating the need for separate metal members and head cap members. This integration simplifies the overall structure and makes the entire container recyclable as a single unit.
Solution Approach 2:
The patent changes the material parameter from metal to paper-based material for the reinforcement structures. The reinforcement structure is made of paper material with increased density or layered construction to achieve the necessary strength without requiring metal components. This material parameter change enables the entire container to be recyclable while maintaining structural integrity.
2Ease of manufacture
If a storage container is made of paper material to simplify recycling, then the container is easy to recycle, but it becomes vulnerable to external impacts and buckling loads
Solution Approach 1:
The patent employs composite material structures where multiple paper-based layers are combined to create a reinforcement structure with enhanced mechanical properties. The cover includes a paper-based reinforcement structure with potential variations in density, layering, or fiber orientation that provides impact resistance and buckling resistance while maintaining paper material recyclability throughout the entire container.
Solution Approach 2:
The patent applies local quality enhancement by concentrating reinforcement structures at critical areas of the cover where strength is most needed, such as the sealing flange area and regions susceptible to buckling. This localized reinforcement provides necessary strength at key points while keeping the overall container simple and fully recyclable.
3Adaptability or versatility
If separate head cap members are used for different storage container types, then the container can be customized for specific uses, but production costs increase
Solution Approach 1:
The patent designs the cover with an integrated reinforcement structure that serves multiple functions simultaneously: sealing, reinforcement, and adaptability for different container types. The modular cover design allows it to function as both a sealing element and a structural reinforcement component, eliminating the need for separate head cap members for different container configurations and reducing production costs.
