Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plectrum is held between the fingers during strumming, then the musician can control the plectrum to play accurately, but the plectrum may slip, move, or shift due to smooth surface and sweaty fingers

Engineering Contradiction:

Improvestability of plectrum gripVSAvoidgrip control

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a plectrum holder as an intermediary device between the fingers and the plectrum. The holder includes a finger loop that receives the finger and a plectrum loop that secures the plectrum, with a connection between them. This intermediary structure prevents direct contact between sweaty fingers and the plectrum, eliminating slipping and shifting while maintaining control.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the plectrum holder uses a monolithic formation with predetermined angle between loops, then stability is improved, but the device complexity increases

Engineering Contradiction:

Improvestability of plectrum positionVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The plectrum holder is segmented into distinct functional components: a finger loop for receiving the finger, a plectrum loop for securing the plectrum, and a connection between them. The predetermined angle (e.g., 90 degrees) between the loops creates stable geometric relationships that maintain plectrum positioning without requiring complex mechanisms.

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If the plectrum loop and finger loop are monolithically formed, then manufacturing precision is improved, but the ease of manufacture decreases

Engineering Contradiction:

Improvealignment precision of loopsVSAvoidmanufacturing process simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The finger loop, plectrum loop, and their connection are merged into a single monolithic structure formed from one piece of material. This eliminates the need for separate parts and assembly operations, ensuring precise alignment and predetermined angles are maintained throughout manufacturing. The unified structure guarantees consistent geometric relationships between components.

Inventive Principle:

Principle #5Merging (Combining)
