Pendulum Closure for Direction-Independent Decanter Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for water decanters are complex, leading to incomplete reclosure and potential contamination, as they require manual operation and often allow pouring only in one direction.
Innovation Solution
A self-sustaining closure device with a swinging lid and pendulum system that automatically opens and closes the pouring opening based on the container's orientation, using cantilever arms and sealing lips for reliable fixation and direction-independent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual closure device is used, then the container can be closed, but it requires additional manual effort and often allows pouring only in one direction
Solution Approach 1:
The closure device automatically opens and closes itself based on the container's orientation. The pendulum mechanism detects when the container is tilted for pouring and automatically triggers the lid to open, then closes it when the container is upright, eliminating the need for manual operation.
Solution Approach 2:
The closure device uses a dynamic pendulum mechanism that responds to changes in container orientation. The pendulum's position changes with the container's tilt, dynamically controlling the lid's opening and closing states based on real-time orientation rather than requiring manual intervention.
2Reliability
If a complex closure device is used, then the container can be sealed, but it leads to incomplete reclosure and potential contamination
Solution Approach 1:
The closure device ensures reliable sealing by automatically returning to the closed position when the container is upright. The pendulum mechanism self-corrects the lid position, ensuring complete reclosure without manual intervention, which prevents contamination.
Solution Approach 2:
Instead of requiring manual closing action, the device inverts the approach by using gravity and the pendulum mechanism to automatically pull the lid closed when the container is upright, ensuring reliable sealing through passive gravitational force rather than active manual operation.
3Adaptability or versatility
If a fixed lid mechanism is used, then the structure is simple, but it cannot allow automatic opening based on container orientation
Solution Approach 1:
The lid is transformed from a fixed structure to a dynamic swinging mechanism connected to a pendulum. This allows the lid to automatically open in any direction when the container is tilted, providing direction-independent pouring capability while maintaining relatively simple construction.
Solution Approach 2:
The closure device is segmented into independent functional components: the frame, the swinging lid, and the pendulum mechanism. This segmentation allows each component to perform its specific function independently, enabling automatic opening in any direction while keeping the overall structure manageable.

Function Achieved in This Case
Ensures reliable automatic opening and closing of the container without additional manual effort, preventing contamination and allowing pouring in any direction, while being reusable and cost-efficient.
Implementation Method 1
the lid and pendulum are configured to rotate with respect to the closure opening when the container is held in a slanted or horizontal manner
Implementation Method 2
at least one sealing lip arranged at an outer wall of the frame, which comes to rest against an inner wall of the container when the closure device is inserted into the pouring opening of the container

AI summary
A closure device for a container, and preferably for a water decanter, comprising a frame comprising a closure opening and which is preferably round and configured for insertion into a pouring opening of the container, a lid, which is connected to a pendulum and which is suspended in the closure opening of the frame, and configured to swing therein, wherein the lid is configured to close and seal the closure opening when the container is substantially upright, and wherein the lid and pendulum are configured to rotate with respect to the closure opening when the container is held in a slanted or horizontal manner. The closure device preferably comprises at least one cantilever arm secured to an inner wall of the frame at a first end and connected to the lid at a second end so that the lid is configured to swing with respect to the closure opening.
