Dual-Lid Container With Opposing Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for consumer items, such as flavour pouches, lack separate and independently accessible compartments, which can lead to contamination and complexity in manufacturing and assembly.
Innovation Solution
A container design featuring a body portion with a curved base wall and two removable lids, where one compartment is convex and the other concave, allowing for separate and independent access while discouraging simultaneous opening to minimize contamination, and simplifying manufacturing by eliminating the need for permanent connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single compartment container is used, then the structure is simple, but contamination risk increases when multiple items are stored
Solution Approach 1:
The container is divided into multiple separate compartments (first compartment for unused items, second compartment for used items) that are physically isolated from each other by the base wall. This segmentation allows independent storage and access to different item types or usage stages, preventing cross-contamination while maintaining a relatively simple overall container structure.
2Reliability
If multiple compartments are provided with separate access, then contamination is prevented, but the lid structure becomes complex
Solution Approach 1:
The lid system is segmented into two separate lids (first lid and second lid) that can be independently removed and replaced. Each lid provides independent access to its corresponding compartment without requiring complex hinge mechanisms or interconnected structures, simplifying the overall lid design while maintaining separate access capability.
Solution Approach 2:
The compartments are arranged in different spatial dimensions (opposite sides of the base wall) rather than stacking one above the other. This dimensional arrangement allows each compartment to have its own lid that attaches to the body portion in a straightforward manner, avoiding the need for complex multi-layer lid structures.
3Stability of the object's composition
If permanent connection means (hinge) are used to attach lid to body, then lid stability is improved, but manufacturing and assembly complexity increases
Solution Approach 1:
The permanent connection means (hinge) are extracted from the design entirely. Instead of using hinges to permanently attach the lid to the body portion, the invention employs simple removable lids that attach and detach directly. This extraction eliminates the manufacturing and assembly complexity associated with hinge mechanisms while providing sufficient stability for the intended use.
4Strength
If lids are connected to each other, then structural integrity is improved, but ease of operation decreases
Solution Approach 1:
The lids are segmented into separate, independent units (first lid and second lid) that are not connected to each other. This segmentation allows each lid to be easily removed and replaced independently without the mechanical complexity of connecting mechanisms, while the overall structural integrity is maintained through the separate attachment of each lid to the body portion.
