Steam-Cooking Basket With Removable Rotary Tool for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food preparation appliances with a non-removable rotary tool in the bottom of the container complicate cleaning and tool changes, limiting versatility in culinary preparations.
Innovation Solution
A household appliance with a removable rotary tool and a steaming basket featuring a shutter element at the orifice to prevent food from falling, allowing easy tool removal and cleaning, and enabling the use of different tools for various preparations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotary tool is fixed in the bottom of the container, then the structural integrity is maintained, but the ease of cleaning and tool replacement deteriorates
Solution Approach 1:
The rotary tool is divided into separable components: the tool body and the gripping member. The gripping member remains fixed in the container bottom while the tool body can be removed for cleaning or replacement, resolving the contradiction between ease of cleaning and structural integrity.
Solution Approach 2:
The gripping member is extracted and left fixed in the container bottom, while the removable tool body can be easily detached. This allows the tool to be cleaned or replaced without removing the entire assembly, maintaining structural integrity while improving ease of operation.
2Adaptability or versatility
If the rotary tool is fixed in the bottom of the container, then the structural stability is maintained, but the adaptability for different culinary preparations deteriorates
Solution Approach 1:
The tool system is segmented into a permanent gripping member and a replaceable tool body. This allows users to swap tool bodies for different culinary preparations while the gripping member remains fixed, providing versatility without compromising structural stability.
Solution Approach 2:
The gripping member serves as a universal interface that can accommodate different tool bodies for various culinary preparations. This multi-functionality approach allows the same base structure to support multiple tools, enhancing adaptability while maintaining structural stability.
3Ease of operation
If the orifice in the basket bottom is left open for tool passage, then the ease of tool insertion is improved, but food loss through the orifice worsens
Solution Approach 1:
The shutter element is made mobile, automatically opening when the gripping member passes through and closing when the tool is removed. This dynamic behavior allows easy tool insertion while preventing food loss, resolving the contradiction between operational ease and substance loss.
Solution Approach 2:
The shutter element acts as an intermediary mechanism between the open orifice and the food contents. It selectively opens to allow tool passage and closes to prevent food loss, mediating between the need for easy tool insertion and the need to prevent food loss.
