Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical musical instruments face challenges in providing easy and intuitive access to a wide range of pickup configurations, with current systems often requiring complex memorization, slow selection processes, and inadequate visual feedback, making it difficult for musicians to quickly switch between desired pickup configurations during performance.
Innovation Solution
A string musical instrument with a user interface featuring clear illuminated momentary buttons or touch pads, controlled by a microcontroller, allowing quick access to all possible pickup connections, and a unique LED display for intuitive configuration selection and feedback, enabling rapid switching between pickup configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of toggle switches, buttons, push/pull switches and/or knobs are used to provide rapid access to different pickup configurations, then the number of selectable combinations increases, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The invention divides the control interface into minimal segments (single toggle switch and single rotary switch) that collectively control multiple pickup configurations. Instead of having one switch per configuration, the system segments the control into two independent switches that work together to select from numerous combinations, thereby reducing overall device complexity while maintaining versatility.
Solution Approach 2:
The two switches serve multiple functions: the toggle switch selects between pickup positions (neck, middle, bridge) while the rotary switch selects between wiring configurations (series, parallel, phase). This multi-functionality allows a minimal number of controls to access a large number of pickup combinations, resolving the contradiction between versatility and complexity.
2Loss of information
If LCD displays are used to show pickup configuration selections, then information can be displayed, but the ease of operation and visibility deteriorate when the instrument is worn on a strap at a distance from the user's eyes
Solution Approach 1:
The invention replaces electronic LCD displays with mechanical visual indicators (LEDs) that are optically visible from a distance. This substitution of display technology eliminates the visibility problems associated with LCDs on strap-worn instruments, allowing musicians to see their pickup configuration selections clearly during performance without compromising ease of operation.
Solution Approach 2:
The system uses color-changing LEDs to indicate different pickup configurations and states. Different colors or lighting patterns provide immediate visual feedback about the current selection, making it easy for musicians to understand their configuration status at a glance without requiring close viewing or complex display interpretation.
3Loss of information
If constellation of light emitting diodes (LEDs) are arrayed about the instrument for visual indication, then pickup configuration can be indicated, but the ease of operation deteriorates as the user must employ a great deal of mental processing to ascertain the chosen pickup selection
Solution Approach 1:
The visual indication system is segmented into specific, localized LED groups that correspond to each pickup position and wiring configuration. Rather than a scattered constellation of LEDs requiring interpretation, the segmented arrangement provides organized, intuitive feedback that reduces mental processing while maintaining clear information display.
4Adaptability or versatility
If scroll-wheel interface is used to allow selection of pickup combinations, then a continuous range of options is available, but the speed of selection deteriorates when the desired configuration is not stored in adjacent positions
Solution Approach 1:
The control system is segmented into two independent switches that can be operated simultaneously and independently. This segmentation eliminates the sequential scrolling motion required by scroll-wheels, allowing musicians to jump directly to any pickup configuration combination by simply setting the toggle and rotary switches to the desired positions, thereby dramatically improving selection speed while maintaining full versatility.
Solution Approach 2:
The switches are designed to be set to desired positions in advance or directly, rather than requiring sequential scrolling through intermediate positions. This preliminary action capability allows musicians to prepare or immediately select any pickup configuration without the time-consuming process of scrolling through adjacent positions, resolving the speed versus versatility contradiction.

AI summary
A string musical instrument, such as an electric guitar, comprises a plurality of sound pickups and a user interface which allows the user rapid access to various configurations of pickup settings and connections. An embodiment of the musical instrument has a user interface which allows quick access to all forty-seven possible pickup connections available in a guitar having three single-coil pickups. Another embodiment of the invention allows rapid to access a large number of possible pickup connections made possible with the use of dual coil pickups, or a combination of single-coil and dual-coil pickups on a single guitar. The different pickup configurations are accessed via user operated controls such as clear illuminated momentary buttons or touch pads. Although the musical instrument provides a large number of accessible pickup configurations, a user display makes the determination of the pickup configuration intuitive and relatively simple.
