Multi-Coil Pickup System for Stringed Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stringed instrument pickups are static and fail to provide options for customizing electrical signal output, leading to imprecise sound reproduction and occupying valuable space on the instrument, with multiple pickups degrading sound quality due to placement and harmonic mix changes.
Innovation Solution
A single stringed instrument pickup with multiple coils wound around a single bobbin body, allowing users to select different coils for customizable electrical signal generation through various magnetic and impedance configurations, eliminating the need for external signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pickups are used to provide customization options, then adaptability is improved, but device complexity and space occupation increase
Solution Approach 1:
The pickup is segmented into multiple independent coils (first coil, second coil, third coil) that can be selectively activated. Each coil can be independently controlled through separate terminals, allowing the user to segment the pickup functionality and select only the needed coils for specific sound characteristics, thereby reducing overall complexity while maintaining adaptability.
Solution Approach 2:
A single pickup unit is designed to perform multiple functions by incorporating multiple coils that can be activated individually or in combination. This universal design replaces the need for multiple separate pickups, providing customization options while reducing the total number of pickup components required in the instrument.
2Adaptability or versatility
If multiple pickups are installed to offer customization, then adaptability is improved, but the instrument occupies more space
Solution Approach 1:
Multiple coil assemblies are merged into a single pickup unit that can be installed in one location on the instrument. The first coil, second coil, and third coil are combined within one pickup housing, allowing the instrument to occupy less space while still providing multiple customization options through selective coil activation.
Solution Approach 2:
A single pickup unit is designed to perform multiple functions by incorporating multiple coils that can be activated individually or in combination. This universal design replaces the need for multiple separate pickups, providing customization options while reducing the total number of pickup components required in the instrument.
3Device complexity
If traditional single coil pickup is used, then device complexity is reduced, but adaptability and sound reproduction precision are limited
Solution Approach 1:
The pickup is segmented into multiple independent coils (first coil, second coil, third coil) that can be selectively activated. Each coil can be independently controlled through separate terminals, allowing the user to segment the pickup functionality and select only the needed coils for specific sound characteristics, thereby reducing overall complexity while maintaining adaptability.
4Adaptability or versatility
If multiple coils are added to a single pickup, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The pickup is segmented into multiple independent coils (first coil, second coil, third coil) that can be selectively activated. Each coil can be independently controlled through separate terminals, allowing the user to segment the pickup functionality and select only the needed coils for specific sound characteristics, thereby reducing overall complexity while maintaining adaptability.
Solution Approach 2:
Multiple coils are nested within a single pickup housing structure, with each coil wound around a common bobbin body. This nested arrangement allows the coils to be manufactured and assembled in a compact configuration, reducing the overall complexity of the pickup assembly while maintaining the ability to select and activate individual coils.

AI summary
A stringed instrument pickup with multiple selectable coils can be utilized in a system to provide a diverse range of sound characteristics from at least one moving string under tension. A first wire can be connected to a first terminal of a first bobbin body prior to the first wire being wound around the first bobbin body a first number of times and then connecting the first wire to a second terminal of the first bobbin body. A second wire may be connected to the second terminal of the first bobbin body before winding the second wire around the first bobbin body a second number of times and then connecting the second wire to a third terminal of the first bobbin body. The first bobbin body is subsequently mounted onto a stringed instrument.
