Solution Overview

Problem

Household electrical appliances often have user interfaces that occupy valuable space and confuse users with numerous controls, making them difficult to navigate, especially for those with little experience.

Innovation Solution

A system featuring 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, eliminating the need for external controls and displays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional user interface with control switches and touch screens is integrated into the appliance, then the appliance can be directly controlled, but it occupies considerable space on the outer enclosure

Engineering Contradiction:
Improvedirect control capabilityVSAvoidouter enclosure space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The user interface functions are extracted from the appliance body and placed on separate removable bodies. Each body contains an electronic device with memory and antenna that can be independently held and applied to the appliance, eliminating the need for a permanent control panel on the appliance enclosure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary communication system using radio frequency signals between the removable bodies and the appliance. The appliance contains communication means that interact with the electronic devices on the bodies, allowing control without direct physical interface elements on the appliance surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the user interface includes many controls and switches to handle increasing technological content, then the appliance functionality is enhanced, but users are likely to be confused

Engineering Contradiction:
Improvefunctionality coverageVSAvoiduser interface clarity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control functions are segmented into multiple specialized bodies, each designed for specific tasks or functions. This allows users to only interact with the relevant body for their current need, rather than facing a single complex interface with all functions. Each body can be independently designed with simplified controls appropriate to its specific function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows dynamic selection and combination of different bodies based on user needs. Users can choose which body to use at any given time, and the system adapts to the selected body's capabilities. This dynamic approach replaces static comprehensive interfaces with flexible, context-specific interaction.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If control elements are integrated into the appliance enclosure, then the appliance structure is compact, but the user interface is less flexible and adaptable

Engineering Contradiction:
Improveappliance structureVSAvoiduser interface flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The user interface transitions from a static integrated structure to a dynamic removable system. Bodies can be added, removed, or swapped based on user needs, allowing the interface to adapt while the appliance structure remains stable and unchanged.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The appliance is designed to work with multiple different body types through a universal communication interface. The same appliance can accommodate various bodies with different functions, making the system multi-functional without requiring multiple appliance variants or complex integrated controls.

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