Closure and lid and method of forming closure and lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinkware lids fail to effectively prevent spills when in closed positions and are not easily removable for cleaning, leading to maintenance issues.
Innovation Solution
A closable lid assembly with a manually movable slider mechanism, featuring magnetic coupling between upper and lower sleds, which slides between closed and open positions, and includes a gasket for sealing and a vent mechanism to allow air flow during pouring, allowing for easy disassembly and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closure lid is designed to seal the container opening, then spill prevention is improved, but the lid becomes difficult to remove for cleaning
Solution Approach 1:
The lid assembly is divided into separate components: a lid body, a closure mechanism, and a slider. The closure can be detached from the lid body by removing the slider, allowing the closure to be separately cleaned while maintaining the sealing function when assembled.
2Reliability
If a slider mechanism is added to control opening closure, then spill prevention is improved, but device complexity increases
Solution Approach 1:
The closure mechanism is extracted as a separate removable component from the lid body. The slider serves as a simple retention feature rather than a complex locking mechanism, allowing the closure to be easily removed and reattached without complicated assembly steps.
3Strength
If the slider is permanently attached to the lid, then structural integrity is improved, but ease of cleaning is reduced
Solution Approach 1:
The slider is designed with dynamic retention - it holds the closure in place during normal use through friction and geometry, but can be easily removed by applying slight lateral force. This allows the system to transition between a secured state (during use) and a disassembled state (for cleaning).
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 lid assembly effectively prevents spills by securely sealing the container and allows easy cleaning by being removable, while the vent mechanism facilitates air flow during pouring, enhancing user convenience.
Implementation Method 1
a magnet assembly including a magnet and a distal end configured to contact the closure when the closure is in the closed position. The magnet assembly can be configured to generate a magnetic force that is effective to retain the closure 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 formed from upper and lower sled elements that are magnetically coupled to one another.
