Sink Drain-Engaging Bowl With Separate Food and Fluid Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food preparation and serving bowls lack a solution for effectively separating cleaned food from uncleaned components during preparation, leading to inconvenience and potential contamination, especially when using a sink with a drain, as clean food can become mixed with remnants and the drain can become blocked.
Innovation Solution
A drain-engageable bowl with an axial passage and annular projection that allows for separate fluid drainage from the bowl and sink, featuring a sealable closure and optional check valve to prevent backflow, enabling independent use of the bowl and sink with a flexible engagement that allows tilting and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bowl is used for food preparation over a sink, then food can be cleaned and separated from remnants, but the drain can become blocked and clean food can become mixed with uncleaned components
Solution Approach 1:
The device divides the sink space into two separate functional zones: an inner bowl area for cleaning and preparing food, and an outer sink area for holding uncleaned ingredients and remnants. The axial passage and annular projection create independent drainage pathways, allowing each zone to drain separately without mixing contents, thus preventing contamination and drain blockage
Solution Approach 2:
The device acts as an intermediary structure between the food being prepared and the sink drain. By positioning the bowl within the sink and providing separate drainage paths through the axial passage and annular projection, it mediates the separation of clean food items from uncleaned remnants while maintaining independent drainage functionality
2Object-affected harmful factors
If cleaned food is positioned on a counter for separation, then contamination is prevented, but additional cleaning is required and time is consumed
Solution Approach 1:
The device merges the food cleaning, separation, and drainage functions into a single integrated unit. The bowl with axial passage allows food to be cleaned and separated within the same structure that provides drainage, eliminating the need to transfer food to a counter and avoiding additional cleaning steps
3Temperature
If a pan is used for cooling food in a sink, then cooling efficiency is improved, but the sink surface becomes blocked and unusable
Solution Approach 1:
The device nests the bowl within the sink space, allowing the bowl to be positioned in the sink for cooling purposes. The annular projection and axial passage design enables the bowl to occupy the sink's drainage area without blocking the sink surface, maintaining both cooling efficiency and sink usability

AI summary
A drain engageable bowl having an interior cavity with an opening at a bottom end thereof. The opening aligns with an axial passage running though an annular projection connected to the bowl and aligned with the opening. The annular projection is adapted to frictionally engage with an interior of a sink drain, and hold the bowl elevated above the lower surface of a sink surrounding the drain. Sealable openings in the sidewall of the annular projection provide an actuable drain for fluid from the sink keeping it separated from the interior cavity of the bowl.
