Solution Overview

Problem

Existing cooking attachments for heatable vessels in food processors face challenges in efficiently separating and managing steam and condensate flows, leading to increased water usage and prolonged heating phases due to direct contact between food and base openings, which impedes steam flow and condensate drainage.

Innovation Solution

The design features a funnel-shaped base with separate steam and condensate openings, protected by collar elements and spacers that create flow channels for low-resistance steam and condensate passage, ensuring efficient separation and rapid drainage of condensate back into the vessel, thereby reducing water usage and heating time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the base has openings for steam and condensate flow, then steam can enter the cooking attachment and condensate can drain, but food may block the openings and impede flow

Engineering Contradiction:
Improvecooking speedVSAvoidflow reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces collar elements as intermediary structures that project into the openings from the base. These collar elements serve as mediators between the food and the openings, preventing food from directly blocking the openings while still allowing steam and condensate to flow through. The collar elements create a protective barrier that maintains reliable flow paths.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the openings into distinct steam openings and condensate openings, with collar elements specifically positioned at steam openings. This segmentation allows different functions (steam entry and condensate drainage) to be optimized separately, with collar elements protecting only the steam openings from food blocking while maintaining open paths for condensate flow.

Inventive Principle:
Principle #1Segmentation

2Productivity

If steam openings are positioned higher on the base, then steam can enter the cooking attachment effectively, but condensate may flow into the steam openings and interfere with steam flow

Engineering Contradiction:
Improvesteam generation efficiencyVSAvoidcondensate interference
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The collar elements act as intermediaries that selectively allow steam to pass through while blocking condensate flow into the steam openings. The collar elements are positioned to create a flow path that permits upward steam movement while preventing downward condensate flow, thus mediating between the conflicting requirements of steam access and condensate exclusion.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies local quality by providing collar elements only at specific locations (steam openings) rather than uniformly across the entire base. The collar elements create localized protection zones around steam openings, allowing condensate to flow freely in other areas while preventing condensate intrusion only where steam enters the cooking attachment.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If the base is flat, then manufacturing is simple, but condensate drainage is inefficient due to lack of directional flow

Engineering Contradiction:
Improvebase manufacturing simplicityVSAvoidcondensate drainage speed
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent introduces a slope to the base, creating a curved or inclined surface that directs condensate flow toward the condensate opening. This curvature modification maintains relative manufacturing simplicity while dramatically improving condensate drainage efficiency by utilizing gravity-assisted directional flow rather than relying solely on capillary action or pressure differentials.

Inventive Principle:
Principle #14Spheroidality (Curvature)

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This configuration allows for faster food preparation without increasing heat output, as it optimizes steam and condensate flow, reducing liquid requirements and shortening the heating phase by ensuring condensate is reused in the steam cycle.

Implementation Method 1

The slope of the base relative to a horizontal plane facilitates the drainage of condensate from the steaming attachment into the food processor bowl via the base opening

Methodology Applied
Scientific EffectGravity: Gravitation

Implementation Method 2

at least one circumferential section of the steam opening, facing away from the lowest section, has a collar element projecting from the base. The collar element protects the steam opening from the passage of condensate flowing towards the vessel

Methodology Applied
Scientific EffectPhysical barrier protection: Physical Containment

Implementation Method 3

The base of the cooking attachment can have a plurality of spacers projecting from the base on the side facing the interior of the cooking attachment to space away the food being prepared in the cooking attachment from the base opening, wherein the base opening is at least partially surrounded by the spacers in the circumferential direction
