Solution Overview

Problem

Existing extractor hoods require different platform designs for various installation situations, limiting flexibility and necessitating multiple stock models for different configurations, making it difficult to adapt to changing installation needs.

Innovation Solution

An extractor hood with a platform device that includes a housing and blower system, featuring adjustable outlets for air discharge, allowing the same platform to be used in multiple installation scenarios by switching the blower device's orientation to accommodate different discharge directions, such as rearward, upward, or lateral air flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different platform designs are used for various installation situations, then the extractor hood can be adapted to different discharge directions, but the device complexity and inventory requirements increase

Engineering Contradiction:
Improveadaptability to different installation situationsVSAvoidplatform device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The blower device is designed with adjustable orientation capability, allowing it to be rotated or repositioned within the housing to change the discharge direction. This dynamic adjustment mechanism enables a single platform device to adapt to different installation situations (rearward, upward, or lateral discharge) without requiring multiple fixed-design platforms, thereby resolving the contradiction between adaptability and device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The platform device is designed as a universal unit that can perform multiple functions by adjusting the blower orientation. The same housing and blower assembly can serve different discharge directions, making one platform device replace multiple specialized platforms, thus reducing inventory needs while maintaining versatility across different installation scenarios

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

2Productivity

If multiple platform models are kept in stock for different configurations, then customer requests can be fulfilled quickly, but the inventory costs and storage requirements increase

Engineering Contradiction:
Improveinstallation speedVSAvoidinventory quantity
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

By designing a universal platform device with adjustable blower orientation, the system eliminates the need to maintain multiple specialized platform models in inventory. A single universal platform can be configured for different discharge directions during installation, significantly reducing inventory quantity requirements while maintaining the ability to fulfill various customer requests efficiently

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

Solution Approach 2:

The invention changes the approach from having different physical platform models to having one platform model with adjustable parameters (blower orientation). This parameter-based configuration allows a single inventory item to serve multiple installation needs, reducing stock requirements while maintaining installation speed through quick reconfiguration rather than model switching

Inventive Principle:
Principle #35Parameter changes
