Fret Lighting Device for Stringed Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for learning to play stringed instruments are time-consuming and require significant human instruction, and existing LED display technologies often require modification of the instrument, resulting in lower quality instruments.
Innovation Solution
A portable, wireless LED display device that can be installed on existing stringed instruments, controlled via a smartphone, to provide guided LED cues for proper finger placement and chord playing, using light strips aligned with frets and strings, with a flexible circuit board for mounting and microcontrollers for sequencing illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED display technology is built into physical guitars, then learning guidance functionality is provided, but the quality of the musical instrument deteriorates and custom manufacturing is required
Solution Approach 1:
The patent introduces a separate LED display device that attaches to the guitar neck without modifying the instrument itself. This intermediary device serves as the learning guidance tool while preserving the original instrument quality, resolving the contradiction between providing functionality and maintaining instrument reliability
Solution Approach 2:
The learning guidance system is segmented into a separate, removable component rather than being integrated into the guitar body. This allows the LED display functionality to be provided independently, eliminating the need for custom manufacturing and preserving the original instrument's quality
2Loss of information
If traditional teaching methods are used, then human instruction is provided, but significant time and repetitive exercises are required
Solution Approach 1:
The patent replaces the mechanical system of human instruction with an automated LED display system that provides visual guidance. This substitution eliminates the need for repetitive exercises and significantly reduces learning time while maintaining instruction quality through programmable LED patterns that show exact finger placements
3Adaptability or versatility
If a portable display device is created, then the device can be installed on existing instruments, but the device size and complexity must be minimized
Solution Approach 1:
The patent uses flexible circuit boards and thin film structures to create a compact display device that can conform to the guitar neck surface. This flexibility allows the device to be installed on existing instruments without adding significant bulk or complexity, maintaining adaptability while minimizing device structure
