Solution Overview

Problem

Existing cooking attachments for food processors do not efficiently manage condensate flow, leading to increased water usage and prolonged heating times due to direct contact between food and the base openings, which impedes steam and condensate flow.

Innovation Solution

A cooking attachment with a capillary system that directs condensate into the food processor vessel using capillary action, combined with a base design featuring spacers and tapered base openings to separate and optimize steam and condensate flow, reducing resistance and facilitating quicker cooking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the base of the cooking attachment has openings for steam and condensate flow, then steam can enter the cooking attachment and condensate can drain, but food may come into direct contact with the base openings which impedes steam and condensate flow

Engineering Contradiction:
Improvecooking speedVSAvoidflow resistance
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The base opening is segmented into two distinct functional zones: a steam opening region and a condensate opening region. This segmentation allows steam and condensate to flow through separate areas, preventing mutual interference and ensuring that food contact with one region does not block the other flow path, thereby maintaining low flow resistance and efficient cooking

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the base opening are assigned different local qualities: the steam opening region is optimized for steam ingress while the condensate opening region is optimized for condensate egress. This local differentiation ensures that each flow type has its own optimal pathway, reducing flow resistance and preventing food contact from blocking the wrong opening type

Inventive Principle:
Principle #3Local quality

2Productivity

If condensate is collected in the cooking attachment, then it can be drained back into the container, but water usage increases and heating time is prolonged

Engineering Contradiction:
Improvecooking efficiencyVSAvoidheating time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

A capillary structure acts as an intermediary element between the cooking attachment interior and the container. This capillary mediator enables selective transport of condensate back into the container while blocking steam flow, allowing efficient water recovery without requiring full drainage cycles that would prolong heating time

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The capillary structure utilizes surface tension and capillary pressure parameters to control fluid transport. By designing the capillary dimensions and material properties, the system changes the transport parameters to favor condensate回流 while maintaining steam barrier function, thus improving cooking efficiency without extending heating time

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the base opening allows both steam and condensate flow, then both functions are served, but the opposing flows interfere with each other increasing resistance

Engineering Contradiction:
Improveflow managementVSAvoidflow interference
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The base opening is divided into a steam opening region and a condensate opening region, creating separate flow paths for steam and condensate. This spatial segmentation eliminates flow interference by ensuring that steam entering through one region does not conflict with condensate draining through another region, while still serving both functions through the integrated base structure

Inventive Principle:
Principle #1Segmentation
