Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stringed musical instruments face challenges in maintaining pitch stability and sound quality over time, as conventional electromechanical devices can compromise the tonal purity and richness of the instrument when used for amplification and tuning.
Innovation Solution
An onboard electronic system integrated into the tailpiece and chinrest of the instrument, featuring an amplification unit, controllers, and a battery-powered setup, allows for synchronous fine-tuning control of pitch, tone, and amplitude, enabling players to modify and amplify sound in real-time without degrading the instrument's sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional electromechanical sound transducers and vacuum tube amplifiers are used to achieve high sound intensity, then sound intensity is improved, but tonal quality deteriorates
Solution Approach 1:
The patent introduces an electronic signal processing system as an intermediary between the string vibrations and the final sound output. The system captures string vibrations via pickups, processes them through electronic circuits that preserve tonal characteristics, and then amplifies the processed signal, thereby achieving both high sound intensity and preserved tonal quality
Solution Approach 2:
The patent replaces conventional electromechanical sound transducers and vacuum tube amplifiers with an electronic system that uses electromagnetic pickups and solid-state or digital signal processing. This substitution eliminates the tonal degradation associated with traditional electromechanical components while maintaining the ability to produce high sound intensity
2Stability of the object's composition
If automatic tuning devices are connected to strings to maintain pitch stability, then pitch stability is improved, but sound purity and tone quality deteriorate
Solution Approach 1:
The patent introduces an electronic tuning device as an intermediary that connects to the instrument's existing electrical system rather than directly to the strings. The device processes pitch information electronically and provides tuning adjustments through the amplification system, thereby maintaining pitch stability without degrading the purity of the original sound signal
Solution Approach 2:
The patent replaces mechanical tuning devices that physically interact with strings with an electronic tuning system that uses electromagnetic sensors and digital signal processing. This substitution allows for precise pitch control through electronic means while leaving the mechanical string system untouched, thus preserving sound purity
3Measurement precision
If electronic circuitry is integrated into the tailpiece and chinrest for synchronous fine control, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple control functions (amplification, tone control, tuning) into a single integrated electronic system housed within the existing tailpiece and chinrest structures. By merging these functions into one unified system rather than separate components, the patent achieves high control precision while minimizing the increase in overall device complexity
Solution Approach 2:
The patent designs the integrated electronic system to perform multiple functions simultaneously - amplification, tone modification, and pitch control - all through a single circuitry integration. This multi-functionality approach allows precise control of multiple parameters without proportionally increasing device complexity, as the system handles multiple tasks through shared electronic components

AI summary
An onboard electronic system and associated method enables a player of an acoustic stringed instrument to control an electronic signal for modifying and amplifying sound while playing an instrument. The onboard electronic system is embedded in the tailpiece and/or the chinrest portions and/or shoulder-rest portion of the stringed instrument, and includes at least one pickup, a battery-powered amplification unit and at least one controller. The method includes steps for controlling sound amplification and tonal modification onboard an acoustic stringed instrument. The steps include sensing vibration from strings with a pickup, generating an electrical signal and transmitting the electrical signal to an amplification unit via an input cable, and modifying the electrical signal in response to one or more controllers located onboard the instrument.
