Solution Overview

Problem

Existing cooktops with integrated downdraft hoods require labor-intensive operations for removing and cleaning the collecting tray, which hampers efficiency in maintenance and hygiene.

Innovation Solution

The cooktop employs magnetic coupling means for the collecting tray, allowing for quicker installation, removal, and simplification of cleaning by using a plurality of magnetic elements for fixation to the support element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to fix the tray to the support element, then the tray is securely fixed, but the operation to remove and clean the tray becomes labor-intensive

Engineering Contradiction:
Improvefixation reliabilityVSAvoidtray removal ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical screw fixation system with a magnetic field-based fixation system. Magnets embedded in the support element automatically hold the tray in place through magnetic attraction, eliminating the need for screws. This substitution maintains secure fixation while enabling easy tray removal by simply overcoming the magnetic force, directly resolving the contradiction between fixation reliability and ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic fixation system provides self-aligning and self-holding functionality. When the tray is placed on the support element, the magnetic fields automatically engage to secure it without requiring manual screw tightening. For removal, the user only needs to lift the tray slightly to break the magnetic hold, making the entire fixation and release process self-service oriented and eliminating labor-intensive operations.

Inventive Principle:
Principle #25Self-service

2Reliability

If screws are used to fix the tray, then the tray remains stable during use, but cleaning and maintenance time increases

Engineering Contradiction:
Improvetray stabilityVSAvoidcleaning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The magnetic fixation system replaces time-consuming screw operations with instantaneous magnetic engagement and release. During cleaning, the tray can be quickly removed by overcoming the magnetic force and reattached by simply placing it back, reducing cleaning time significantly while maintaining tray stability during cooking operations through consistent magnetic holding force.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If magnetic elements are used for coupling, then tray installation and removal become quicker, but the fixation strength may be reduced

Engineering Contradiction:
Improvetray installation speedVSAvoidfixation strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The magnetic fixation system concentrates magnetic force at specific contact points between the tray and support element, creating localized high-strength fixation zones. This distributed magnetic coupling provides sufficient holding strength during normal use while allowing quick release when lifting force is applied, resolving the contradiction between installation speed and fixation strength.

Inventive Principle:
Principle #3Local quality
