Solution Overview

Problem

Conventional home appliances require manual reactivation after a predetermined time, causing inconvenience as users must physically interact with them to resume operations, lacking remote-control options in various modes.

Innovation Solution

A home appliance system enabling remote-control modes such as unavailable, one-time-available, and always-available modes, controlled via a portable terminal, with activation/deactivation based on door opening/closing, key inputs, cycle completion, and error detection, and displaying mode states through light-emitting elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the home appliance automatically turns off after a predetermined time duration, then energy consumption is reduced, but the user must physically move to the appliance to re-operate it, increasing inconvenience

Engineering Contradiction:
Improveenergy consumptionVSAvoiduser convenience
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

A portable terminal acts as an intermediary between the user and the home appliance, enabling remote operation through wireless communication. The terminal receives user inputs and transmits control signals to the appliance, eliminating the need for physical presence while maintaining energy-saving automatic shutdown functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/physical interaction system with an electronic communication system. Instead of requiring physical movement to the appliance, the control interface is substituted with a portable terminal that communicates wirelessly, transforming the operation mechanism from mechanical to electronic.

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

2Device complexity

If the home appliance provides fixed operation modes, then the system is simple to implement, but it cannot adapt to different user needs for remote control availability

Engineering Contradiction:
Improvesystem simplicityVSAvoidremote control adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic remote control modes that can switch between unavailable, one-time available, and always available states based on user selection. This dynamic adaptability allows the system to adjust its behavior to different user needs while maintaining a relatively simple underlying architecture through mode-based configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameter of remote control availability by offering different modes (unavailable, one-time, always). This parameter change approach allows the same hardware to adapt to different user requirements without requiring complex customizations, maintaining simplicity while achieving versatility.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the manipulation panel is always active, then the user can easily operate the appliance, but energy consumption increases and safety is reduced when the door is closed

Engineering Contradiction:
Improveoperation accessibilityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The manipulation panel transitions from a static always-active state to a dynamic state that activates only when the door is open. This dynamic behavior reduces energy consumption during door-closed periods while ensuring full accessibility when the door is open, balancing energy efficiency with operational convenience.

Inventive Principle:
Principle #15Dynamics

4Reliability

If the home appliance requires manual reactivation after temporary stop, then the system ensures user presence and safety, but it increases user inconvenience and reduces productivity

Engineering Contradiction:
Improvesafety controlVSAvoidoperation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The portable terminal serves as an intermediary that enables remote reactivation of the appliance. This allows the user to restart operations without physically moving to the appliance, maintaining safety protocols while significantly improving operational efficiency and reducing the time lost during temporary stops.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system prepares for potential reactivation needs by maintaining the capability for remote operation. When a temporary stop occurs, the user can immediately initiate reactivation through the portable terminal without needing to physically approach the appliance, thus maintaining productivity while ensuring controlled operation.

Inventive Principle:
Principle #10Preliminary action
