Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for picking up tones from musical instruments with multiple sound sources, such as keyboard percussion instruments, often alter the acoustic characteristics of the sound sources and complicate installation and maintenance due to the need for numerous sensors.
Innovation Solution
A musical instrument pickup system featuring a vibrating body positioned to face multiple sound sources, excited by sound waves, and a sensor detecting the vibrations of this body, which allows for efficient sound pickup without direct contact with the sound sources, simplifying installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor is attached directly to each sound source to pick up tones, then sound pickup accuracy is improved, but acoustic characteristics of the sound source are altered
Solution Approach 1:
The patent introduces a vibrating body as an intermediary element that indirectly contacts the sound source. The sound source vibrates without direct sensor attachment, and this vibration is transmitted to the vibrating body which then contacts the sensor. This mediator approach allows accurate vibration detection while preserving the natural acoustic characteristics of the sound source.
2Measurement precision
If a sensor is provided for each sound source to detect vibrations, then measurement precision is improved, but device complexity increases due to numerous sensors and complicated wiring
Solution Approach 1:
The patent merges multiple detection functions into a single sensor that detects vibrations of a common vibrating body. Instead of having separate sensors for each sound source, one sensor monitors the vibrations transmitted through the vibrating body, thereby reducing the number of sensors and simplifying wiring while maintaining detection capability.
Solution Approach 2:
The vibrating body serves as a universal transducer that can receive vibrations from multiple different sound sources. A single sensor attached to this universal vibrating body can detect vibrations from any sound source that causes it to vibrate, making the system multi-functional without requiring multiple specialized sensors.
3Reliability
If multiple sensors are mounted on sound sources to detect tones, then sound detection capability is improved, but ease of operation deteriorates due to troublesome mounting and maintenance
Solution Approach 1:
By combining multiple detection functions into a single sensor-vibrating body system, the patent reduces the number of components that need to be installed and maintained. Instead of mounting and maintaining multiple sensors on different sound sources, only one sensor needs to be attached to the vibrating body, significantly simplifying installation and maintenance operations.
