Hinged Lid Integrated Storage Compartment Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lids with multiple parts often get lost during use due to their unattached nature, failing to effectively serve dual purposes of carrying unused or used products separately from the package contents.
Innovation Solution
A container design featuring a base and cap with a hinged lid that provides access to an integrated storage compartment, allowing the lid to move between open and closed positions, and includes child-resistant features like press-and-twist release mechanisms, ensuring secure engagement and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lid is made as multiple unattached parts to create storage compartments, then the storage functionality is improved, but the parts can get lost during use
Solution Approach 1:
The patent combines multiple lid parts into a single integrated cap assembly where the storage compartment walls are formed as integral portions of the cap structure. The hinge connects the lid to this integrated cap, ensuring all components remain attached and cannot be lost separately while maintaining the multi-compartment storage functionality.
2Adaptability or versatility
If the lid is made as multiple unattached parts, then the storage compartment creation is improved, but the ease of operation deteriorates due to risk of loss
Solution Approach 1:
The patent merges multiple lid components into a single integrated cap structure with integral storage compartment walls, connected via a hinge to the lid. This integration maintains the ability to create separate storage compartments while eliminating the operational inconvenience of handling and risking loss of separate unattached parts.
3Reliability
If the cap is designed with engagement features for the base, then the security of the cap is improved, but the device complexity increases
Solution Approach 1:
The patent segments the engagement mechanism into distinct functional elements: threads on the cap for screwing onto the neck portion, and a separate snap-fit engagement between the cap's open edge and the body portion's groove. This segmentation provides secure multi-stage engagement while keeping each individual mechanism simple and manufacturable.

AI summary
A container includes a base and a cap that engages a portion of the base. The base has a body portion and a neck portion, where the neck portion defines an open end. The cap has a housing and a hinged lid. The housing defines an open cavity in the cap, and the neck portion extends into the open cavity. The hinged lid is movable between an open position providing access to the cavity and a closed portion sealing the cavity.
