Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple microphones are arranged near striking surfaces with holders attached to shells or rims, then sound quality is improved, but device complexity and installation time increase significantly

Engineering Contradiction:

Improvesound qualityVSAvoidequipment quantity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple microphones into a single integrated sound pickup device with a unified housing structure. The housing contains multiple microphones positioned at different locations and orientations, eliminating the need for separate holder attachments on each drum component while maintaining comprehensive sound capture capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sound pickup device is designed as a universal multi-functional unit that can capture sounds from multiple drum components simultaneously. The integrated housing with multiple microphones oriented in different directions enables the device to function as multiple individual microphone units would, reducing overall equipment quantity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple microphones are arranged near striking surfaces with holders attached to shells or rims, then sound quality is improved, but installation time increases significantly

Engineering Contradiction:

Improvesound qualityVSAvoidinstallation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines multiple microphones into a single integrated sound pickup device with a unified housing structure. The housing contains multiple microphones positioned at different locations and orientations, eliminating the need for separate holder attachments on each drum component while maintaining comprehensive sound capture capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The microphones are pre-positioned and fixed within the housing during manufacturing, with their orientations and positions optimized for capturing drum sounds. This preliminary arrangement eliminates the need for on-site adjustment and positioning of individual microphones, significantly reducing installation time.

Inventive Principle:

Principle #10Preliminary action
