Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple sound data transfer routes are configured to enable comprehensive fault detection, then the ability to identify faulty routes is improved, but the device complexity increases due to multiple transfer routes and comparison mechanisms

Engineering Contradiction:

Improvefault detection precisionVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates multiple copies of sound data transfer routes (first transfer route and second transfer route) that process the same sound data independently. By comparing results from these duplicate routes, the system can identify faults with high precision while maintaining manageable complexity through systematic replication rather than complex multi-dimensional routing.

Inventive Principle:

Principle #26Copying

2Measurement precision

If sound data is transferred through multiple routes for comparison, then fault identification capability is improved, but the loss of time increases due to multiple transfer and comparison operations

Engineering Contradiction:

Improvefault identification capabilityVSAvoidtime for transfer and comparison

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by configuring multiple sound data transfer routes in advance before actual sound processing begins. The routes are pre-established and ready for simultaneous operation, allowing fault detection to occur during normal sound processing without requiring additional sequential comparison steps, thus minimizing time loss.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If multiple sound data transfer routes are implemented, then the reliability of the sound system is improved through fault detection, but the ease of operation deteriorates due to complex route management and diagnosis

Engineering Contradiction:

Improvesound system reliabilityVSAvoidroute management ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the result generating unit compares output from multiple transfer routes and automatically identifies which route is faulty. This closed-loop feedback system eliminates the need for manual route management or complex diagnostic procedures, maintaining high reliability while preserving ease of operation through automated fault identification.

Inventive Principle:

Principle #23Feedback
