Heating cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating cookers with stirring functions struggle to effectively mix cooking materials containing both liquid and solids, as solids with lower specific gravity float on the liquid surface and are not adequately stirred, and high-speed stirring can cause solids to break apart.
Innovation Solution
A heating cooker with a stirring body that includes both a lower blade to push solids near the bottom surface towards the inner peripheral surface and an upper blade to cause solids above the lower blade to sink towards the bottom surface, improving mixing efficiency without excessive breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional stirring body rotates near the bottom surface of the cooking container, then the stirring function operates at normal speed, but solids with lower specific gravity float on the liquid surface and are not adequately stirred
Solution Approach 1:
The stirring body is segmented into multiple blades positioned at different vertical levels (upper blades and lower blades). The upper blades are positioned to reach the liquid surface to stir floating solids, while the lower blades operate near the bottom surface. This segmentation allows simultaneous stirring of solids at different depths without requiring high-speed rotation that would break apart the solids.
2Quantity of substance
If the stirring body rotates at high speed to stir floating solids, then mixing efficiency improves, but solids break apart and lose their shape
Solution Approach 1:
The stirring body is divided into multiple blades at different vertical positions. The upper blades engage floating solids at the liquid surface while the lower blades stir solids near the bottom, achieving comprehensive mixing without requiring high rotational speed that would damage solid integrity.
Solution Approach 2:
The stirring action is extended from a single horizontal rotation to a multi-dimensional approach with blades distributed vertically throughout the liquid depth. This vertical dimensionality allows the stirring body to reach solids at different levels simultaneously, improving mixing efficiency without increasing rotational speed.
3Device complexity
If a single rotating stirring body is used, then the device structure remains simple, but it cannot effectively stir both floating solids and solids near the bottom surface
Solution Approach 1:
The stirring body is segmented into multiple blades positioned at different vertical levels within a single rotating structure. This segmentation enables the stirring body to effectively stir solids throughout the entire liquid depth while maintaining a relatively simple integrated structure that rotates as one unit.
Solution Approach 2:
The multi-blade stirring body performs multiple functions simultaneously: the upper blades stir floating solids at the liquid surface while the lower blades stir solids near the bottom surface. This multi-functionality is achieved within a single rotating stirring body structure, avoiding the need for multiple separate stirring mechanisms.
