Pivotable Lid Assembly for Controlled Dispensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers lack effective mechanisms for controlled and portioned dispensation of contents, leading to overconsumption and potential contamination.
Innovation Solution
A lid assembly comprising an upper and lower lid, where the upper lid is pivotable to create a dispensation chamber and tortuous path, allowing controlled dispensation of contents by adjusting the position of the divider relative to the dispensation opening, facilitating user control over the amount dispensed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional container lid is used, then the structure is simple, but the dispensation control is poor leading to overconsumption
Solution Approach 1:
The lid assembly is divided into an upper lid and a lower lid that can move relative to each other. The upper lid segments the dispensing function by creating a movable dispensation opening that can be positioned at different locations along the containment portion, enabling portion control while maintaining a relatively simple overall structure.
Solution Approach 2:
The upper lid is designed to be movable relative to the lower lid, transforming the static lid structure into a dynamic system. The upper lid can pivot between a first position (closed) and a second position (open), and the dispensation opening can be positioned at different locations along the containment portion, providing operational control for portion management.
2Ease of operation
If the lid is fully open for dispensation, then access is easy, but contamination risk increases
Solution Approach 1:
The lid assembly enables partial opening for dispensation rather than requiring full opening. The upper lid can be positioned to create a tortuous path that limits direct access to the contents while still allowing controlled dispensing, reducing contamination risk while maintaining ease of operation for the intended dispensing function.
Solution Approach 2:
The containment portion acts as an intermediary structure between the user and the container contents. The tortuous path created by the movable upper lid and containment portion provides a controlled interface that allows dispensation while minimizing direct exposure to contaminants, serving as a protective mediator.
3Object-affected harmful factors
If a tortuous path is created for dispensation, then contamination is reduced, but the dispensation path complexity increases
Solution Approach 1:
The dispensation path is segmented into distinct sections: the dispensation opening in the upper lid, the elongated recess in the containment portion, and the lower opening in the lower lid. This segmentation creates the tortuous path while using simple geometric features rather than complex mechanical components.
Solution Approach 2:
The tortuous path is created dynamically through the relative positioning of the movable upper lid and the stationary containment portion, rather than through a fixed complex structure. The path geometry changes with lid position, simplifying the overall device design while achieving contamination reduction.
