Solution Overview

Problem

Existing extractor hood designs face challenges in achieving flexible design options and simplified manufacturing processes, as they often require complex attachment methods like welding or separate profiles, which can result in visible tape or limited geometry and material choices.

Innovation Solution

An extractor hood with a panel system comprising at least two panel parts connected via a single adhesive or magnetic connecting layer to the device body, allowing for secure attachment without visible fasteners and enabling flexible design and simplified manufacturing by eliminating the need for profiles or complex screw connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the decorative panel is glued directly to the device body or attached via a separate profile, then the panel can be secured to the device body, but the attachment method becomes complex and the tape becomes visible in the side view

Engineering Contradiction:
Improvepanel attachment securityVSAvoidattachment structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The front of the device body is divided into a first region (visible front surface) and a second region (rear surface), with the connecting layer applied only to the second region. This segmentation allows the panel to be securely attached while keeping the connection method hidden from view.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A connecting layer (adhesive or magnetic) serves as an intermediary between the panel and the device body, enabling secure attachment without visible fasteners or complex mechanical connections. The connecting layer mediates the connection while remaining concealed on the rear surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the front of the device body is offset backwards to create a step for panel insertion, then the panel can be attached, but welding and grinding are required and the depth of the step cannot be chosen arbitrarily

Engineering Contradiction:
Improvepanel attachment simplicityVSAvoidfront surface flatness
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The connecting layer is applied in the depth dimension (on the rear surface of the front) rather than creating a visible step in the front surface dimension. This allows the front surface to remain flat while still providing attachment capability through the connecting layer positioned in the third dimension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If a separate profile part is provided for panel attachment, then the panel can be securely mounted, but the production process becomes more complex and requires additional components

Engineering Contradiction:
Improvepanel mounting securityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connecting layer is integrated directly onto the front of the device body rather than being a separate profile component. This merging of the attachment mechanism with the device body eliminates the need for separate profile parts while maintaining secure panel mounting.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connecting layer serves multiple functions: it provides secure attachment, remains hidden from view, and can be applied directly to the device body surface. This multi-functional approach eliminates the need for dedicated profile components that would otherwise be required.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If the decorative panel covers only part of the front of the device body, then the electronic components are protected, but the design options for the appliance front are limited

Engineering Contradiction:
Improvedesign flexibilityVSAvoidfront geometry constraints
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The panel configuration is made dynamic and flexible through the use of multiple independently attachable panel parts that can be arranged in various patterns and configurations on the front surface, allowing diverse design options while maintaining protection of electronic components.

Inventive Principle:
Principle #15Dynamics
