Solution Overview

Problem

The operation of kitchen appliances with control panels, such as hobs, extractor hoods, and lighting, is complex due to the need to recognize and interact with multiple control elements at different positions, which can be difficult and cumbersome.

Innovation Solution

A kitchen furniture system with a freely movable and wireless control panel that uses a sensor system to detect its position and properties, allowing for intuitive control of various appliance functions without physical connection, using technologies like wireless communication and sensors to adjust processes like temperature, lighting, or water supply based on the panel's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If control elements are positioned at different fixed locations on kitchen appliances, then each appliance can be operated independently, but the user must move between multiple positions to operate different appliances, increasing operation complexity and time

Engineering Contradiction:
Improveease of operationVSAvoidtime to operate multiple appliances
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines multiple control elements into a single centralized control panel that can control multiple kitchen appliances (hob, extractor hood, lighting) from one location. This merging of control functions allows the user to operate all appliances from a single position, eliminating the need to move between different appliances and their respective control elements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control panel is designed with universal functionality to control multiple different types of kitchen appliances through a single interface. The system can adapt to control various appliances (hob zones, extractor hood, lighting) using the same control elements, making the control system versatile and reducing the number of separate control locations needed.

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

2Adaptability or versatility

If control elements are distributed at different positions on appliances, then each appliance has its own control, but the layout can make it difficult to identify control positions and increase operational labor

Engineering Contradiction:
Improvecontrol flexibilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple distributed control elements into a single integrated control panel, simplifying the overall control system architecture. Instead of having separate control elements on each appliance, all controls are combined in one location, reducing the complexity of identifying and accessing multiple control positions while maintaining the ability to control all appliances.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If control panels are fixed on appliances, then the control layout is stable, but the control position cannot be adjusted to different locations on the work surface

Engineering Contradiction:
Improvecontrol position stabilityVSAvoidcontrol position flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent implements a movable control panel that can be dynamically repositioned to different locations on the work surface while maintaining stable operation. The control panel can be freely moved and repositioned by the user, yet once positioned, it provides stable and reliable control of all appliances. This dynamic positioning capability allows the control system to adapt to different user preferences and kitchen layouts.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces traditional mechanical cable connections with wireless communication technology, allowing the control panel to be freely positioned without physical constraints. The wireless communication system enables the movable control panel to maintain stable electrical and data connections with the appliances regardless of its position on the work surface.

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