Solution Overview
Problem
Existing sensor assemblies for stringed musical instruments lack an integral mounting system and integration of the electrical and mounting systems, resulting in limited tonal versatility and output.
Innovation Solution
A sensor assembly with a primary winding made of aluminum, acting as a mounting member, and secondary windings that transform primary electromagnetic flux into secondary current, integrated with a magnetic field barrier for enhanced tone and reduced environmental interference, offering a current-driven design with improved bass, volume, and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electromagnetic sensors are mounted on a stringed musical instrument using a separate mounting assembly, then the sensor can be installed, but the visual impact is high and the tone output is limited to a single value
Solution Approach 1:
The patent combines the mounting assembly and the electromagnetic sensor into a single integrated unit. The mounting assembly includes a body with a recess that receives the electromagnetic sensor, and the entire assembly is mounted as one piece to the instrument. This integration reduces visual impact while maintaining installation capability and enables multiple tone outputs through multiple sensors positioned at different locations.
Solution Approach 2:
The integrated mounting assembly serves multiple functions: it provides mechanical support for the sensor, enables mounting to the instrument, and houses multiple sensors to produce multiple tone values. The body of the mounting assembly acts as both a structural support and a mounting interface, eliminating the need for separate mounting components.
2Loss of energy
If the primary winding is made of copper, then the electrical conductivity is high, but the resistance is higher compared to aluminum
Solution Approach 1:
The patent changes the material parameter of the primary winding from copper to aluminum. This material substitution reduces the electrical resistance of the winding, thereby reducing energy loss. The aluminum winding is designed with appropriate geometry to maintain the necessary inductance and coupling characteristics while achieving lower resistance compared to traditional copper windings.

The sensor assembly provides an integrated mounting system, enhanced tonal characteristics with increased bass and volume, and clear highs, suitable for both acoustic and electric instruments, with flexibility in design and installation options.
Implementation Method 1
The primary winding creates a primary current from a disruption in the magnetic field by the movable strings
Implementation Method 2
The primary winding creates a primary current from a disruption in the magnetic field by the movable strings and the primary current creates a primary electromagnetic flux
Implementation Method 3
The at least one secondary winding transforms the primary electromagnetic flux into a secondary current adapted to pass out the stringed musical instrument
