Closure and lid and method of forming closure and lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinkware lids lack effective mechanisms for selectively closing and opening to prevent spills while allowing easy consumption and cleaning, with many designs failing to provide secure locking and easy operation.
Innovation Solution
A closable lid assembly featuring a movable slider with a tab or handle that slides between closed and open positions, includes elastic legs for secure engagement with the lid, air vents for pouring, and magnetic or detent mechanisms for locking, allowing easy removal and reattachment for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a movable slider mechanism is added to the lid, then the ease of operation for opening and closing is improved, but the device complexity increases
Solution Approach 1:
The lid is divided into functional segments: a fixed lid body and a movable slider component. The slider can be independently removed from the lid, allowing the lid body to be cleaned separately. This segmentation enables improved ease of operation for opening/closing while managing complexity through modular design.
Solution Approach 2:
The slider is designed as a dynamic component that can move between locked and unlocked positions, and can be completely removed from the lid. This dynamic capability provides easy operation for opening and closing the beverage container while the modular nature helps manage overall device complexity.
2Ease of operation
If the slider is made removable from the lid, then the ease of cleaning is improved, but the reliability of the closure mechanism may worsen
Solution Approach 1:
The closure system is segmented into a permanent lid body and a removable slider. The lid body remains reliably attached to the beverage container, while only the slider is removable for cleaning. This segmentation maintains closure reliability while enabling easy cleaning access.
Solution Approach 2:
The slider component is extracted as a separate removable element from the lid assembly. This allows the slider to be easily removed and cleaned separately, while the lid body remains intact and reliably closed on the container, preserving closure reliability.
3Reliability
If magnetic or detent locking mechanisms are added, then the reliability of the closed position is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed as self-service through magnetic attraction or detent engagement that automatically locks the slider in place without requiring additional active components. The slider simply snaps into position on the lid, providing reliable locking while minimizing added complexity.
Solution Approach 2:
Complex mechanical locking systems are replaced with simpler magnetic or detent-based mechanisms. The magnetic attraction or detent engagement provides reliable locking of the slider to the lid with minimal mechanical complexity, improving reliability without significantly increasing device complexity.
Applied Scientific Principles
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 solution provides a secure seal to prevent spills, easy operation for user convenience, and facilitates cleaning by allowing the slider to be removed and reattached, enhancing the usability and functionality of drinkware lids.
Implementation Method 1
The first leg and the second leg can be configured to resiliently engage the first guide and the second guide
Implementation Method 2
The slider and the lid can include a series of magnets for locking the slider in both the closed position and in the opened position and for maintaining the slider on the lid

AI summary
An example lid assembly can include a lid and a slider. The lid can include a wall defining a recess. The slider can be configured to slide in the recess and can be configured to move between a closed position where the slider covers the opening to aid in preventing spilling of contents of the container and an opened position where the slider uncovers the opening such that the contents of the container can be consumed. The slider can be configured to be removable from the lid and can be replaced back on the lid. Additionally, the slider can be configured to lock into place on the recess in both the closed position and the opened position.
