Device for at least partially closing an opening of a cooking vessel, cooking vessel system and kitchen machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
State-of-the-art cooking vessels lack a precise mechanism for partially closing openings, leading to issues with heat and pressure control, noise from closure elements, and accidental removal, which affects the consistency of cooking results and safety.
Innovation Solution
A device with a support element and plug-in element featuring a locking mechanism that securely attaches to the cooking vessel's opening edge, preventing accidental removal and allowing controlled steam escape, while maintaining pressure and heat conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closure element is placed on the opening to partially close it, then steam can escape and heat/pressure can be maintained, but the closure element may lift off and create audible noise
Solution Approach 1:
The closure element is divided into a support element that rests on the opening edge and a plug-in element that inserts through the opening. This segmentation allows the support element to provide stable support while the plug-in element with locking means prevents unwanted movement and noise
Solution Approach 2:
The locking means is designed to be brought into a locking position that interacts with the opening edge to prevent pull-out before cooking begins. This preliminary securing action ensures the closure element remains stable during cooking, preventing lift-off and associated noise
2Ease of operation
If the lid is completely removed to access the cooking vessel, then the user can add ingredients, but heat and pressure cannot be maintained
Solution Approach 1:
Instead of completely removing the lid, the device partially closes the opening by inserting the plug-in element through the opening while the support element rests on the opening edge. This partial closure maintains sufficient heat and pressure for cooking while allowing the device to be added or removed easily
3Ease of operation
If the plug-in element can be easily removed for access, then the user can add ingredients, but the closure element may be inadvertently removed during cooking
Solution Approach 1:
The locking means is preliminarily positioned to engage with the opening edge, creating a secure connection that prevents inadvertent removal during cooking. The user must deliberately manipulate the device to release the locking means, ensuring intentional removal only
4Temperature
If the opening is completely closed with a lid, then heat and pressure are maintained, but the user cannot add ingredients or access the vessel
Solution Approach 1:
The device provides partial closure of the opening rather than complete closure. The plug-in element closes most of the opening to maintain heat and pressure, while the opening itself remains accessible for adding ingredients when the device is not in place
