Solution Overview

Problem

Traditional gauges for musical instrument strings are often designed for electrical wiring and can damage the delicate surfaces of instruments, while manual reading of string gauge leads to inconsistencies in sound quality due to unknown or mismatched string gauges.

Innovation Solution

An electronic string measurement system with a gauge body and calipers that engage the string to measure its width, generating a signal indicative of the width, and optionally includes a tuner to determine the acoustic frequency, with a display to communicate the results.

VSEngineering Contradiction Analysis

1Measurement precision

If traditional gauges are used for measuring string gauge, then the measurement function is provided, but the delicate surfaces of instruments may be damaged

Engineering Contradiction:

Improvestring gauge measurementVSAvoidsurface damage to instrument

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The caliper tips are covered with a soft coating material that is compliant and non-marring to the instrument surface. This flexible coating allows the calipers to engage the string for measurement while preventing damage to the delicate surfaces of the instrument bridge or tailpiece where the measurement is taken.

Inventive Principle:

Principle #30Flexible shells and thin films

2Ease of operation

If manual reading of string gauge is used, then the measurement process is simple, but inconsistencies in sound quality result from unknown or mismatched string gauges

Engineering Contradiction:

Improvemanual measurement processVSAvoidstring gauge accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The manual reading mechanism is replaced with an electronic digital display that automatically shows the measured string gauge. The electronic gauge provides precise numerical readings eliminates the subjectivity and error associated with manual visual estimation, ensuring accurate string gauge identification for consistent sound quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electronic gauge provides immediate visual feedback through a digital display showing the exact string gauge measurement. This feedback mechanism allows the user to confirm the measurement accuracy and make informed decisions about string replacement, eliminating the uncertainty of manual reading methods.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If electronic gauge with digital display is used, then measurement accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvestring gauge measurement accuracyVSAvoidelectronic gauge structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The electronic gauge is designed to perform multiple functions: measuring string gauge width, displaying the measurement digitally, and potentially storing measurement data. By combining these functions into a single integrated device, the complexity is justified by the enhanced precision and additional capabilities that benefit the user.

Inventive Principle:

Principle #6Universality (Multi-functionality)
