Solution Overview

Problem

Existing extractor hoods face challenges in secure and aesthetically pleasing wall-mounting, particularly with sloping hoods where visible mounting structures detract from the visual appearance and require complex assembly methods.

Innovation Solution

An adapter element made of sheet metal with hanging projections and screw holes is used between the fan box and the mounting wall, allowing for easy and secure attachment of the extractor hood without visible mounting components, utilizing tabs and arms for stable engagement and concealment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional wall mounting methods with visible mounting structures are used, then secure fastening is achieved, but aesthetic appearance deteriorates due to visible mounting components

Engineering Contradiction:
Improvefastening securityVSAvoidvisual appearance
Core Design Contradiction:
StrengthVSShape

Solution Approach 1:

A mounting plate is introduced as an intermediary component between the extractor hood and the wall. The mounting plate contains recesses that completely conceal the suspension projections, while still providing secure mechanical fastening through screw connections. This mediator element hides the mounting structure from view while maintaining fastening strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The suspension projections are nested within recesses of the mounting plate. The projections extend from the extractor hood and are received by corresponding recesses in the mounting plate, with the recesses positioned to completely hide the projections from external view. This nesting arrangement conceals the mounting components while maintaining structural integrity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If complex assembly methods with multiple mounting components are used, then secure fastening is achieved, but assembly simplicity deteriorates

Engineering Contradiction:
Improvefastening securityVSAvoidassembly simplicity
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The mounting plate combines multiple functions into a single component: it provides structural support for wall mounting, contains recesses to conceal suspension projections, and serves as the interface for screw fastening. This merging of functions reduces the number of separate components and simplifies the assembly process while maintaining secure fastening.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If mounting structures are made visible for easy assembly, then assembly simplicity is improved, but aesthetic appearance deteriorates

Engineering Contradiction:
Improveassembly accessibilityVSAvoidvisual appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The mounting plate acts as an intermediary that provides accessible screw mounting points while concealing the suspension projections. The recesses in the mounting plate are positioned to completely hide the projections from external view, while the plate itself provides a clean, finished appearance with visible only the necessary screw heads for assembly.

Inventive Principle:
Principle #24Intermediary (Mediator)
