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 region for course and option information, and a single variable input unit that allows users to select and convert input information without needing multiple input units, reducing clutter and improving usability by concentrating controls around the rotary knob.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple select units and display units are provided for different functions, then the washing apparatus can provide comprehensive washing options and controls, but the control panel becomes cluttered and the user interface becomes complex and difficult to operate

Engineering Contradiction:
Improvewashing optionsVSAvoiduser interface
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The single variable input unit is designed to perform multiple functions including course selection, option selection, and information input by changing its display content based on the current operation state. This multi-functional design eliminates the need for separate input units for different functions, reducing control panel clutter while maintaining comprehensive washing options

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

Solution Approach 2:

Multiple input units and display units are merged into a single integrated variable input unit and display region. The variable input unit can display different input information sources (course selection, option selection, time input, etc.) and the display region shows corresponding content, consolidating what would traditionally require multiple separate components into one unified interface

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the control panel includes many select units and display units for comprehensive functionality, then the washing apparatus can offer diverse washing courses and options, but the internal space becomes insufficient and the design becomes cluttered

Engineering Contradiction:
Improvewashing coursesVSAvoidcontrol panel design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The variable input unit serves as a universal input device that adapts its function based on the current state of the washing apparatus. It can accept course selections, option selections, time inputs, and other commands through a single interface, eliminating the need for multiple dedicated input units and reducing overall device complexity

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

Solution Approach 2:

The variable input unit dynamically changes its display content and input capabilities based on the current operation state. The control unit controls what information is displayed on the variable input unit and display region, allowing the interface to adapt its complexity to match the current operational context rather than presenting all possible controls simultaneously

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If diverse select units are exposed to users, then the washing apparatus can provide comprehensive control options, but inexperienced users find it difficult to identify and use the required controls

Engineering Contradiction:
Improvecontrol functionsVSAvoidcontrol identification
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The variable input unit displays different input information sources in different operational contexts. When course selection is needed, it displays course options; when option selection is needed, it displays option inputs. This context-specific display quality helps users immediately identify the relevant control function without being confused by irrelevant controls

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The display region provides visual feedback showing the current operation state and the input information that the variable input unit is currently accepting. This feedback mechanism guides users through the operation process by clearly indicating what action is expected next, making the control system intuitive even for inexperienced users

Inventive Principle:
Principle #23Feedback
