Pivoting Non-Spill Lid and Handle for Infant Food Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small food containers often lead to spills, especially when used by infants learning to feed themselves, and traditional removable lids are frequently lost or misplaced, failing to address the issue of mess prevention effectively.
Innovation Solution
A non-spill container assembly featuring a cylindrical receptacle with a threaded lid and a flexible, pivoting handle, incorporating a flexible non-spill diaphragm with audible feedback for secure closure and easy food retrieval, designed to prevent spills and facilitate easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable lid is added to the container, then the container can be closed to prevent spills, but the lid is frequently lost, misplaced and difficult to relocate
Solution Approach 1:
The lid is merged with the container body through an integrated design where the lid forms a continuous piece with the container walls. This eliminates the separate removable lid that gets lost, while maintaining the closure function through the folded flap structure that seals the opening.
Solution Approach 2:
The lid structure is designed to be self-retaining through its folded configuration and friction fit with the container rim. The lid automatically stays in place during use and can be easily removed when needed without requiring separate storage or retrieval actions.
2Ease of operation
If the container opening is left open for easy access, then food retrieval is convenient, but spills occur frequently
Solution Approach 1:
The lid is designed as a dynamic folded flap structure that can be easily opened and closed by the user. When closed, it prevents spills; when opened, it allows easy food access. The flexible nature of the folded flap enables quick transitions between open and closed states.
Solution Approach 2:
The lid is constructed as a thin, flexible folded flap that can bend and fold easily. This flexibility allows the lid to be quickly opened for food access while maintaining an effective seal when closed to prevent spills during transport.
3Reliability
If a threaded lid is used for secure closure, then spill prevention is improved, but the device complexity increases
Solution Approach 1:
The closure mechanism is segmented into simple geometric features: an external threaded rim on the container and a corresponding internal threaded structure on the lid. This segmentation into basic threading elements provides secure closure without requiring complex mechanisms.
Solution Approach 2:
The threaded lid structure serves multiple functions: it provides secure closure through threading, maintains the seal through the folded flap design, and enables easy opening and closing. This multi-functionality reduces the need for additional complex components.
