Solution Overview

Problem

Control interfaces for household appliances have become overly complex as their functionalities have increased, making it difficult for users to access and navigate all operating parameters simply.

Innovation Solution

A control interface with a partly transparent panel that uses tactile inputs and dynamic lighting elements to generate graphic symbols based on appliance operation parameters, allowing for context-specific commands and hiding unnecessary options depending on the appliance's mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If control interfaces incorporate more functionalities and controls to allow full control of appliance functions, then the appliance control capability is improved, but the interface complexity increases making it difficult for users to operate

Engineering Contradiction:
Improveappliance control capabilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control interface dynamically adapts its displayed commands based on the appliance's current operating mode. The control unit selectively displays only relevant commands for the active mode, transforming the static interface into a dynamic one that changes according to operational context, thereby reducing perceived complexity while maintaining full functionality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control interface segments the full set of available commands into mode-specific subsets. Instead of presenting all possible controls simultaneously, the interface divides commands into groups relevant to each operating mode, allowing users to access complete functionality through sequential mode-based exploration rather than overwhelming simultaneous display

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If all possible commands are displayed simultaneously on the control interface, then complete access to appliance functions is provided, but the user interface becomes cluttered and difficult to navigate

Engineering Contradiction:
Improveaccess to appliance functionsVSAvoiduser interface navigability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The interface transitions from a static display of all commands to a dynamic display that adapts in real-time based on the appliance's operating mode. The control unit receives mode information and selectively renders only the subset of commands appropriate for that mode, making the interface both comprehensive and navigable

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different portions of the interface display different information based on local context. The interface applies local quality by showing mode-specific commands in relevant interface regions while hiding irrelevant commands, creating a customized view for each operational context rather than a uniform display of all functions

Inventive Principle:
Principle #3Local quality
