Solution Overview

Problem

Existing extractor hood control systems are cumbersome and unintuitive, especially in dim lighting conditions, as they require users to manually switch on the control panel and position it within their field of vision for function selection and setting, leading to potential accidental settings and complex operation procedures.

Innovation Solution

An extractor hood with a modular operating module featuring a control panel that operates in two modes: a first mode allowing specific function setting by actuating individual areas and a second mode enabling predetermined function setting by actuating multiple areas, reducing accidental settings and simplifying operation by allowing basic functions to be set without explicit selection or activation of the control panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the control panel is arranged out of the user's field of vision to improve appearance and avoid obstruction, then the aesthetic appearance and workspace clearance are improved, but the ease of operation deteriorates as users cannot easily access and adjust functions

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidease of operation
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The control panel is designed to be movable between a first position (protruding from the housing) and a second position (recessed into the housing). This dynamic positioning allows the control panel to be accessible when needed and aesthetically integrated when not in use, resolving the contradiction between appearance and operability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the control panel is switched off to prevent accidental settings, then the reliability against incorrect settings is improved, but the ease of operation deteriorates as users must manually switch it on for every adjustment

Engineering Contradiction:
Improveprevention of accidental settingsVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The control panel is pre-configured with multiple operating modes (first operating mode for specific function setting, second operating mode for predefined function setting) that are automatically activated based on the position or state of the control panel. This eliminates the need for manual switching while maintaining reliability through mode-specific activation requirements.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If individual buttons with printed symbols are provided for each function, then the adaptability and specificity of function control are improved, but the device complexity increases

Engineering Contradiction:
Improvefunction selection capabilityVSAvoidcontrol panel complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control panel areas are designed to serve multiple functions depending on the operating mode. In the first operating mode, individual areas control specific functions; in the second operating mode, combinations of areas control predefined functions. This multi-functionality reduces the need for separate controls while maintaining adaptability.

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