Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual USB recording media insertion is used to load performance and setting data, then data can be transferred to the electronic musical instrument, but the operation becomes cumbersome and complex

Engineering Contradiction:

Improveease of data loadingVSAvoidoperation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical USB insertion method with a wireless communication system. The electronic musical instrument communicates with a mobile terminal via wireless communication to automatically transfer performance data and setting data, eliminating the need for manual USB media insertion and significantly simplifying the data loading operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables automatic data transfer where the electronic musical instrument autonomously communicates with the mobile terminal to retrieve and load performance data and setting data without requiring user intervention for media insertion or file selection, making the system self-service oriented

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If multiple mobile communication terminals are capable of communicating, then more users can access the instrument, but identifying the correct terminal becomes complex

Engineering Contradiction:

Improvemulti-terminal compatibilityVSAvoidterminal identification

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The identification unit receives identification information from multiple mobile terminals and provides feedback to determine which terminal should be connected. The system uses this feedback mechanism to automatically select the appropriate terminal based on stored identification data, resolving the complexity of multi-terminal identification

Inventive Principle:

Principle #23Feedback
