Solution Overview

Problem

Washing machines lack the ability to automatically identify the properties of laundry and adjust their functions accordingly, leading to potential damage or inefficiency when dealing with special loads such as duvets or padded clothing.

Innovation Solution

A washing machine and cloud server system that uses object sensing and machine learning to identify the properties of laundry through sensors and images, determining the optimal wash course by analyzing features like height, weight, and image data, and adjusting operations to prevent issues like water splash and unbalanced power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If washing machine uses basic sensor functions to detect laundry, then device complexity is reduced, but measurement precision and identification accuracy of laundry properties deteriorate

Engineering Contradiction:
Improvesensor system complexityVSAvoidlaundry property identification accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent combines multiple sensing functions (image recognition, weight measurement, volume detection) into an integrated sensing system. The control unit merges data from the image sensor, weight sensor, and volume sensor to comprehensively identify laundry properties, resolving the contradiction by achieving high measurement precision through functional integration rather than through complex individual sensors.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control unit serves multiple functions: it controls washing operations, processes image data, analyzes weight information, calculates volume, and identifies laundry properties. This multi-functional approach allows the system to achieve comprehensive laundry identification without requiring separate complex dedicated sensors for each measurement type.

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

2Measurement precision

If washing machine adds multiple sensors and image analysis capabilities to identify laundry properties, then measurement precision improves, but device complexity increases

Engineering Contradiction:
Improvelaundry property identification accuracyVSAvoidsensing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control unit acts as an intermediary that processes raw sensor data and translates it into meaningful laundry property identification. Instead of requiring complex sensors, the system uses simple sensors whose outputs are processed by the control unit's image processing and analysis capabilities, achieving high measurement precision through intelligent data processing rather than through complex sensing hardware.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces complex mechanical or electronic sensing mechanisms with a combination of simple sensors and software-based image processing. The control unit uses image analysis algorithms to identify laundry properties, substituting what would otherwise require complex physical sensors with computational methods that achieve the same measurement precision with simpler hardware.

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

3Ease of operation

If washing machine uses simple function setting to operate, then ease of operation is improved, but adaptability to different laundry types deteriorates

Engineering Contradiction:
Improvefunction setting simplicityVSAvoidlaundry type adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The washing machine automatically identifies laundry properties using image sensors, weight sensors, and volume sensors, then autonomously determines appropriate washing functions and parameters. The control unit processes sensor data to identify laundry type, material, and characteristics, then automatically selects the optimal wash course without requiring user input, achieving both ease of operation and high adaptability through self-service functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors sensor inputs (image data, weight, volume) and uses this feedback to automatically adjust washing parameters. The control unit processes real-time sensor feedback to identify laundry properties and dynamically selects appropriate washing functions, enabling the machine to adapt to different laundry types while maintaining simple operation for the user.

Inventive Principle:
Principle #23Feedback

4Device complexity

If washing machine lacks automated laundry identification, then device complexity is reduced, but productivity and washing efficiency deteriorate

Engineering Contradiction:
Improveautomation system complexityVSAvoidwashing efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system performs preliminary identification of laundry properties using image sensors, weight sensors, and volume sensors before the washing cycle begins. The control unit analyzes sensor data to determine laundry type and characteristics in advance, then pre-configures optimal washing parameters, enabling efficient washing operations without requiring complex real-time adjustments during the cycle.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The washing machine automatically identifies laundry properties and determines optimal washing parameters without user intervention. The control unit processes sensor data to autonomously select wash courses, water levels, and timing, achieving high productivity through automated decision-making that eliminates manual function setting while maintaining system accessibility.

Inventive Principle:
Principle #25Self-service
