Electrical Food Preparation Appliance With Rotatable Steam Vent Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food preparation appliances lack the ability to modulate the steam exhaust orifice passage section, which is essential for adapting to different cooking recipes and heat-sensitive ingredients, as the passage section cannot be adjusted to suit varying cooking requirements.
Innovation Solution
A household appliance with a removable measuring cap that can occupy multiple stable positions and rotate, allowing the user to vary the steam exhaust orifice passage section by moving or rotating the cap, thereby adjusting the degree of coverage of the steam escape orifices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the steam escape orifice has a fixed passage section, then the device structure is simple, but the adaptability to different cooking recipes and ingredients is poor
Solution Approach 1:
The measuring cap is designed to be rotatable within the opening, allowing the passage section of the steam escape orifice to be dynamically adjusted between multiple stable positions. This enables the user to adapt the steam exhaust capability to different cooking recipes and ingredients by simply rotating the cap to different angular positions, transforming a static structure into a dynamic, adjustable one.
2Productivity
If the steam escape orifice passage section is reduced, then the cooking speed increases for non-heat-sensitive ingredients, but the suitability for heat-sensitive ingredients decreases
Solution Approach 1:
The rotatable measuring cap provides multiple stable positions that correspond to different passage sections of the steam escape orifice. Users can select a smaller passage section (by rotating to certain positions) to accelerate cooking of robust ingredients, or a larger passage section (by rotating to other positions) to protect heat-sensitive ingredients, thus dynamically adapting the cooking process to different ingredient requirements.
Solution Approach 2:
The invention changes the geometric parameter of the steam escape orifice (passage section area) by rotating the measuring cap to different positions. This parameter change allows the system to optimize between cooking speed and ingredient protection depending on the specific cooking task, enabling the same device to handle both fast-cooking robust ingredients and slow-cooking heat-sensitive ingredients effectively.

Function Achieved in This Case
Enables users to adapt the steam exhaust passage section according to the type of food being cooked, ensuring efficient steam escape for heat-sensitive foods and accelerating cooking for less fragile ingredients by reducing the passage section.
