Solution Overview

Problem

Conventional washing apparatuses have complex and dispersed user interfaces, making it difficult for users to select wash courses and options intuitively, with limited ability to add new courses and a cluttered control panel design that is not user-friendly, especially for inexperienced users.

Innovation Solution

A washing apparatus with a simplified user interface featuring a rotary knob for course selection, a display for course and option screens, and a single variable input unit that converts input information, allowing users to select and change options without cluttering the control panel, with light transmission units for intuitive data representation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple select units and display units are provided for diverse wash courses and options, then the washing apparatus can provide comprehensive functions, but the control panel becomes cluttered and difficult to operate

Engineering Contradiction:
Improvewash course selection capabilityVSAvoiduser interface complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges multiple select units and display units into a single integrated touch-sensitive display panel. The display panel combines course selection, option selection, and information display functions into one unified interface, eliminating the need for separate rotary knobs, push buttons, and LED indicators for each function. This consolidation maintains comprehensive wash course capabilities while dramatically simplifying the control panel layout and improving ease of operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The touch-sensitive display panel serves multiple functions simultaneously: it displays wash course information, accepts course selections, presents option selections, and provides feedback to users. This single universal interface replaces numerous specialized components, allowing the system to maintain diverse functionality while reducing physical complexity and improving user interaction.

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

2Adaptability or versatility

If a conventional control panel with multiple dispersed select units is used, then diverse functions can be accessed, but inexperienced users find it difficult to use

Engineering Contradiction:
Improvefunction accessibilityVSAvoiduser experience for inexperienced users
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The touch-sensitive display panel acts as an intermediary between the user and the complex washing machine functions. It provides a intuitive graphical interface that translates user touches into specific course and option selections, while also translating machine status into easily understood visual displays. This intermediary layer shields inexperienced users from the complexity of multiple separate controls while maintaining full access to diverse washing functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The display panel uses visual changes including color variations, brightness adjustments, and graphical element transformations to provide intuitive feedback to users. Different colors and visual states indicate different operational modes, selection states, and machine status, making it easy for inexperienced users to understand what is happening without needing to interpret complex mechanical indicator systems.

Inventive Principle:
Principle #32Color changes

3Area of stationary object

If the control panel internal space is limited, then the device remains compact, but additional user interface functions cannot be added

Engineering Contradiction:
Improvecontrol panel sizeVSAvoiduser interface expandability
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The touch-sensitive display panel provides a dynamic interface that can change its content and functionality based on the current operational context. The same physical panel area can display different information and accept different types of inputs depending on what stage of operation the machine is in, effectively providing expanded functionality within a fixed physical footprint. The interface can be reconfigured software-wise to add or emphasize different functions without adding physical components.

Inventive Principle:
Principle #15Dynamics
