Solution Overview

Problem

Existing household appliance control devices are complex and costly due to the large number of control means and indicator lights, leading to user confusion and space constraints, as well as inefficient use of features depending on the operating mode.

Innovation Solution

A control panel with adaptive functionality where the same control means can control different functions based on the selected operating mode, with display changes indicating function shifts, reducing the number of control means and optimizing space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large number of control means and indicator lights are used to cover multiple functions and operating modes, then the appliance can offer more functions and modes, but the device complexity increases and users find it difficult to operate

Engineering Contradiction:
Improvenumber of functions and operating modesVSAvoidnumber of control means and indicator lights
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single control means is designed to control multiple functions depending on the selected operating mode. The control means is associated with a display that changes to indicate which function is currently active, allowing one physical control element to serve multiple purposes across different operating modes.

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

Solution Approach 2:

The function controlled by the control means changes dynamically based on the selected operating mode. The display associated with the control means evolves to reflect the current function, allowing the control panel to adapt its functionality rather than requiring static controls for each possible function.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple control means are installed to cover all functions, then all functions can be controlled, but the space required on the control panel increases

Engineering Contradiction:
Improvenumber of controllable functionsVSAvoidcontrol panel surface area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

By making the control means universal across different operating modes, the physical space required is reduced. Instead of having separate controls for each function, a single control means handles multiple functions, thereby reducing the total area needed on the control panel.

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

Solution Approach 2:

Multiple control functions are merged into a single control means. The control means is combined with a display element that provides context-specific information about which function is active, merging the control and indication functions into a compact unit.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If different control means are provided for different operating modes, then each mode can be optimized, but the device complexity and cost increase

Engineering Contradiction:
Improveoperating mode functionalityVSAvoidnumber of control means
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control means is designed to be universal rather than mode-specific. A single control means works across multiple operating modes, with the associated display indicating which function is active in each mode. This reduces the total number of control means while maintaining optimized functionality for each mode.

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

4Adaptability or versatility

If a large number of control means are used, then comprehensive control is achieved, but manufacturing cost increases

Engineering Contradiction:
Improvenumber of functionsVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By designing control means that work across multiple operating modes rather than having separate controls for each mode, the bill of materials is reduced. Fewer physical control elements and indicator lights are needed, directly reducing manufacturing costs while maintaining comprehensive function coverage.

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

Solution Approach 2:

Multiple control functions are merged into single control means, reducing the total component count. The combination of control means with associated displays that change based on operating mode creates a more efficient design that uses fewer components overall, reducing manufacturing complexity and cost.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The device has a control panel comprising a control unit (41) e.g. push button or sensitive key, and a processing unit (40) processing control signals provided by the control unit. The control unit controls a function associated to an operation mode of a household appliance, and is associated to a display unit (42). The display unit displays pictograms reflecting a state of the appliance and indicates operation and control possibilities of the appliance. The function and the display unit change according to a selected operation mode of the panel, where the panel has distinct operation modes.
