Multi-compartment Container with Circumferential Weld Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-compartment containers for flat objects face issues such as paper getting caught in weld projections, dirt penetration, surface kinks, and premature wear due to inadequate connections between compartments, leading to handling difficulties and reduced stability.
Innovation Solution
The container features partially connected side walls with circumferential weld seams that create pocket-like compartments with at least one closed side, ensuring edges align for stability and preventing objects from getting between compartments, with a reinforcement layer for added strength and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual compartments are connected with weld patterns that leave edges free, then manufacturing is simplified, but paper gets caught on projections and cannot be pushed in
Solution Approach 1:
The patent applies local quality by differentiating the treatment of compartment edges: some edges are connected with weld seams while other edges remain free or have different connection types. This allows the container to have smooth edges at loading positions (preventing paper catching) while maintaining structural connections at other positions, thus resolving the contradiction between manufacturing simplicity and operational ease.
2Strength
If weld patterns do not reach the edge, then material penetration occurs between compartments, but complete welding provides better structural integrity
Solution Approach 1:
The patent segments the welding pattern into multiple zones: complete weld seams at certain positions for structural integrity, and partial or no welding at edge positions to prevent material penetration. This segmentation allows different functional requirements to be met at different locations, resolving the contradiction between strength and preventing harmful factor entry.
3Stability of the object's composition
If individual compartments are not connected at open sides, then the container is not compact, but connection creates stability
Solution Approach 1:
The patent applies local quality by selectively connecting compartments at specific locations (e.g., at closed sides or partially at open sides) rather than uniformly connecting all edges. This allows the container to achieve sufficient stability at connection points while maintaining overall compactness and flexibility, resolving the contradiction between stability and compactness.
4Ease of operation
If flat objects are pushed in without proper compartment guidance, then objects get between compartments, but proper guidance increases manufacturing complexity
Solution Approach 1:
The patent applies local quality by providing guidance features (such as protrusions or reinforced edges) only at specific locations where objects are most likely to get caught, rather than throughout the entire compartment structure. This localized approach prevents object misplacement while minimizing the increase in manufacturing complexity, resolving the contradiction between operational ease and device complexity.
