Solution Overview

Problem

Conventional clothes treating apparatus control panels lack effective methods for inputting control commands using bioelectric currents, preventing unintended operation, and providing clear recognition of selected commands through varying brightness levels of light emission units.

Innovation Solution

A control panel with light discharge units and light emission units that utilize a controller to adjust the duty cycle of current supply, allowing for distinct brightness levels and patterns, preventing unintended operation and enhancing user recognition of selected commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional control panels are used with physical buttons, then the structure is simple and easy to manufacture, but the panel cannot prevent unintended operation from bioelectric currents and cannot provide clear visual differentiation of selected commands

Engineering Contradiction:
Improveprevention of unintended operationVSAvoidcontrol panel structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces physical mechanical buttons with a touch-sensitive panel that detects bioelectric currents from human contact. This substitution eliminates the need for mechanical switches while adding the ability to distinguish intentional touch inputs from unintended contact, thereby improving reliability without significantly increasing overall system complexity.

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

Solution Approach 2:

The patent introduces light emission units as an intermediary between the control input and the display elements. These light emission units provide visual feedback by illuminating specific areas corresponding to selected commands, creating a clear distinction between selected and unselected options without requiring complex mechanical or electronic changes to the button structure itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If conventional control panels are used with physical buttons, then the device complexity is low, but the panel cannot provide clear visual differentiation of selected commands through brightness levels

Engineering Contradiction:
Improvecommand selection recognitionVSAvoidcontrol panel structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent employs light emission units that change their illumination state based on command selection. By controlling the brightness and presence of light at different panel locations, the system provides clear visual differentiation between selected and unselected commands, ensuring users can easily recognize their input choices without increasing device complexity.

Inventive Principle:
Principle #32Color changes

3Ease of operation

If light emission units are added to provide visual feedback, then command selection recognition is improved, but the device complexity increases

Engineering Contradiction:
Improvecommand recognitionVSAvoidcontrol panel structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the light emission units with the existing button or touch-sensing structure, integrating the visual feedback mechanism into the control panel itself rather than adding separate display components. This integration approach improves ease of operation by providing immediate visual confirmation at the point of interaction while minimizing the increase in overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)
