Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional software is used to match remote control signals, then the device can control multiple household appliances, but the configuration process becomes complex and time-consuming

Engineering Contradiction:

Improveability to control multiple household appliancesVSAvoidconfiguration process complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs automatic appliance identification and remote control signal matching without requiring user intervention. The electronic apparatus autonomously detects appliances, retrieves corresponding remote control codes from a database, and configures the control signals, eliminating the need for manual configuration by users.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Remote control codes for various appliances are pre-stored in a database before actual use. When an appliance needs to be controlled, the system simply retrieves the pre-prepared codes from the database rather than requiring users to search or configure them manually.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If conventional software is used to match remote control signals, then the device can control multiple household appliances, but the matching speed is slow
