Solution Overview

Problem

Current household appliances require users to manually input information about the items to be treated, such as type and condition, which can be time-consuming and creates a barrier to using advanced technology, even though automation can improve treatment results.

Innovation Solution

A domestic appliance with a controller that uses an input control part with a camera and computer-like supplementary control part, possibly external, to recognize items automatically or semi-automatically, eliminating the need for code marks on items and providing users with easy-to-understand input options, allowing for fully or partially automated treatment processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual input of item information is required, then treatment accuracy can be ensured, but ease of operation deteriorates

Engineering Contradiction:
Improveitem information accuracyVSAvoiduser input complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The appliance automatically captures images of items using an integrated camera and processes them through image recognition algorithms to identify item type, material, and condition without requiring user input. The system serves itself by autonomously gathering and analyzing item information.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical input methods (buttons, dials, switches) are replaced with an optical system (camera) and computational image recognition process. The mechanical interaction between user and control panel is substituted by automatic visual detection and digital processing.

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

2Ease of operation

If automation is implemented to improve ease of operation, then device complexity increases

Engineering Contradiction:
Improveautomatic item recognitionVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The camera-based input control part serves multiple functions: capturing item images, detecting item presence, and providing visual feedback to users. This single component replaces multiple separate control mechanisms, reducing overall system complexity despite adding automation capabilities.

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

Solution Approach 2:

The camera acts as an intermediary between the user and the control system. Instead of direct user input or complex sensor arrays, the camera mediates by capturing visual information that is then processed to determine treatment parameters, simplifying the interaction interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If code marks are required on items for detection, then measurement precision improves, but ease of manufacture deteriorates

Engineering Contradiction:
Improveitem detection accuracyVSAvoiditem preparation complexity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The system uses the item's natural visual characteristics (color, texture, shape, patterns) that already exist on the items without requiring any additional marking, coding, or preparation. The item serves itself by providing sufficient visual information in its natural state.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The requirement for artificial code marks is extracted and eliminated from the system. Instead of relying on added markers, the system extracts and utilizes the inherent visual features present on all items, removing the manufacturing burden of applying codes.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If comprehensive sensors are used to eliminate manual input, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improveautomatic information captureVSAvoidsensor system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A single camera-based input control part performs multiple detection functions that would otherwise require separate sensors: identifying item type, detecting item condition, determining item presence, and providing user feedback. This multi-functional approach avoids the complexity of multiple specialized sensors.

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