Solution Overview

Problem

Household electrical appliances often have cluttered user interfaces that occupy valuable space and confuse users, especially those less familiar with the appliances, due to the increasing complexity of controls and switches.

Innovation Solution

A system comprising a household electrical appliance with a compact, RFID-based interaction method using a body with an electronic device and antenna that can be applied to an application surface, allowing for intuitive control through radio frequency communication, reducing the need for external controls and providing a flexible and user-friendly interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional user interface with control switches and pushbuttons is used, then the appliance can be controlled, but the interface occupies considerable space on the outer enclosure

Engineering Contradiction:
Improvecontrol functionalityVSAvoidouter enclosure space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The control interface is extracted from the appliance body and placed on a removable body that can be held by the user. This allows the control functions to be separated from the main appliance structure, freeing up space on the outer enclosure while maintaining full control functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A wireless communication system serves as an intermediary between the appliance and the user's handheld body. The control signals are transmitted wirelessly (via RFID or similar technology), eliminating the need for physical control switches and pushbuttons on the appliance exterior.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple controls and switches are added to handle increasing technological content, then more functions are available, but users become confused

Engineering Contradiction:
Improvefunctional complexityVSAvoiduser confusion
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control interface is segmented into a separate, portable body that contains all controls. This segmentation allows the complex control system to be isolated from the appliance, making the appliance exterior simple and clean while concentrating all control functions in one manageable location that the user can hold and operate intuitively.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system provides intuitive, self-explanatory control through the handheld body interface. The body serves as a self-contained control unit that guides the user through operations without requiring complex appliance-mounted controls, reducing user confusion while maintaining high functional versatility.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If a compact RFID-based interaction method is used, then space is optimized and user-friendliness is enhanced, but the system requires radio frequency communication infrastructure

Engineering Contradiction:
Improvecontrol interface spaceVSAvoidcommunication system requirements
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The traditional mechanical control system (physical switches, buttons, and wiring) is replaced with a radio frequency communication system. This substitution eliminates the need for extensive wiring and physical control interfaces on the appliance, reducing space requirements and simplifying the appliance structure while enabling wireless control through the handheld body.

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