Slow Cooker Lid Latch for Leak-Resistant Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slow cookers face challenges in transporting contents without spillage due to loose lid engagement and lack of secure sealing, leading to potential spillage of liquid foods during movement.
Innovation Solution
A kitchen appliance design featuring a housing with a pivotally mounted handle that secures the lid in sealing engagement with the container rim, utilizing a gasket for a liquid-tight seal and a latching mechanism to prevent leakage, allowing for secure transport while enabling easy lid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is made loosely engaged for easy removal, then ease of operation is improved, but sealing reliability deteriorates causing spillage during transport
Solution Approach 1:
The handle is pivotally mounted to allow dynamic movement between a first position (lid removal) and a second position (sealing engagement). This dynamic mechanism resolves the contradiction by enabling the lid to be easily removed when the handle is in the first position while maintaining secure sealing when the handle is in the second position.
Solution Approach 2:
The handle acts as an intermediary mechanism between the user and the lid sealing system. By pivoting the handle between two positions, it mediates between the conflicting requirements of easy removal and secure sealing, controlling the engagement state of the lid with the container rim.
2Reliability
If the lid is securely engaged to prevent spillage, then sealing reliability is improved, but ease of operation deteriorates making lid removal difficult
Solution Approach 1:
The pivotal mounting of the handle creates a dynamic system where the handle can be easily positioned in either the first or second position. This resolves the contradiction by making lid removal simple (via pivotal movement to first position) while maintaining secure sealing (via pivotal movement to second position).
Solution Approach 2:
The lid assembly is segmented into the lid itself and the pivotally mounted handle mechanism. This segmentation allows the handle to independently control sealing engagement while the lid remains easily removable when the handle is in the appropriate position.
3Device complexity
If conventional slow cooker components are used without secure engagement, then device complexity is reduced, but loss of substance increases due to spillage during transport
Solution Approach 1:
The pivotally mounted handle provides a simple yet effective dynamic mechanism that prevents food spillage during transport. This resolves the contradiction by adding minimal complexity (a single pivotal handle) to achieve the goal of preventing substance loss during movement.
Solution Approach 2:
The handle mechanism is designed to be self-operating through its pivotal movement. When positioned in the second position, it automatically secures the lid to prevent spillage without requiring additional active components or complex control systems.

AI summary
A kitchen appliance includes a housing that defines a cavity. The housing has a housing rim defining an opening to the cavity. A heating or cooling element is disposed within the housing to heat or cool the cavity. A container has a generally hollow interior and a container rim. A lid is sized and shaped to at least partially cover the opening of the container when placed on the container. The lid has an exterior surface and an opposing interior surface. At least one handle is pivotally mounted to one of the exterior surface of the side wall of the housing and the exterior surface of the lid. The handle is pivotable between an engaged position to retain the lid in sealing engagement with the container rim and disengage position to permit the lid to be removed from the container rim.
