Multi-compartment container with a flexible partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-compartment containers used for carrying premeasured baby formulas and granulated food items tend to cross-contaminate contents due to leakage when flipped or moved, making it challenging to meet the dietary needs of small children while traveling.
Innovation Solution
A multi-compartment container with radially extending, flexible partitions that flex against the lid's inner surface, creating a seal to prevent leakage between compartments, and a snap-fit lid attachment for easy dispensing of contents without spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-compartment containers are used to separate different baby formulas, then the contents are separated into different compartments, but the contents leak and cross-contaminate when the container is flipped or moved
Solution Approach 1:
The partition walls are made of flexible material that can deform to seal against the container walls and each other. This flexibility allows the partitions to maintain their sealing function during flipping and movement while still separating the compartments effectively, preventing cross-contamination without compromising ease of operation
Solution Approach 2:
The partition system is designed to be dynamic rather than rigid, allowing the partitions to move and adapt their shape in response to container orientation changes. This dynamic behavior enables the partitions to maintain effective seals during various handling conditions, resolving the contradiction between reliability during movement and ease of operation
2Strength
If rigid partitions are used to separate compartments, then the structural integrity is maintained, but leakage occurs at the partition edges when the container is moved or flipped
Solution Approach 1:
The partition edges are made flexible to conform to the container walls and maintain contact during movement. This flexibility compensates for any gaps or misalignments that occur during handling, ensuring reliable sealing while the overall partition structure maintains sufficient structural integrity to separate compartments
Solution Approach 2:
The partition system likely combines rigid and flexible materials, with the bulk of the partition providing structural integrity and the edges made flexible for sealing. This composite approach allows the partition to simultaneously maintain its shape and seal effectively during dynamic handling conditions

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The flexible partitions effectively prevent cross-contamination by sealing each compartment, ensuring that contents remain separate during use and transport, enhancing the convenience of meeting a child's dietary needs on the go.

AI summary
A container assembly having a container, a lid having a spout, and a partition to separate the container into multiple subcompartments. The partition has a flexible edge which is in contact with an inner surface of the lid. When the lid rotates about the container, the flexible edge is biased against the lid and is capable of being deformed.
