Solution Overview

Problem

Conventional home appliance control systems require users to manually select and change control codes for each appliance, making it cumbersome to control multiple devices using a unified remote control.

Innovation Solution

A wireless network-based integrated remote control system using zigbee communication forms a Wireless Personal Area Network (WPAN) to transmit control messages based on appliance product information, transforming these messages into infrared signals for control, and dynamically updates the list of controllable appliances as the user moves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a unified remote control stores control codes for multiple home appliances, then it can control various appliances, but the user must manually search and select each appliance from a list, increasing operation complexity

Engineering Contradiction:
Improveability to control multiple home appliancesVSAvoidmanual code selection process
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system enables home appliances to automatically transmit their presence information and control codes to the remote control device. When a user approaches an appliance, the appliance self-services by pushing its control information to the remote control, eliminating the need for manual searching and selection from a list.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The remote control device receives real-time feedback from home appliances about their presence and status through automatic information transmission. This feedback mechanism allows the remote control to dynamically update its interface with currently detectable appliances, reducing user effort in navigating through static lists.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the remote control displays a static list of all home appliances, then complete control is possible, but the list does not update when user position changes, reducing operational efficiency

Engineering Contradiction:
Improvecontrol coverage of all appliancesVSAvoidcontrol efficiency based on user position
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The remote control interface dynamically adapts based on user position and movement. As the user moves through different locations in the home, the system automatically updates the displayed appliance list to reflect currently nearby appliances, optimizing control efficiency for the current context while maintaining access to all appliances when needed.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the system uses infrared remote control for each appliance, then reliable control is achieved, but the user needs to hold and aim the remote at each specific appliance, increasing operational steps

Engineering Contradiction:
Improvecontrol signal transmissionVSAvoidpointing and aiming requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The remote control device serves as an intermediary that consolidates control functions. Instead of requiring the user to directly aim at each appliance, the remote control receives automatic information about nearby appliances and mediates the control process by presenting a simplified interface that handles the complexity of appliance identification and signal direction automatically.

Inventive Principle:
Principle #24Intermediary (Mediator)
