Musical Instrument Strap Tension to Rotation Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses for musical instruments struggle to effectively control musical sound based on tension applied to the instrument's strap, as the physical change in strap tension is not easily recognizable, making it difficult for players to control the desired musical tone.
Innovation Solution
The electronic apparatus includes a first component coupled to the strap, a second component coupled to the musical instrument, a generator that produces a rotational movement based on the tension applied to either component, and a rotation detection device that detects the rotation amount, allowing for control of musical sound through recognizable physical changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an extension detection sensor is attached to the strap to detect tension, then musical sound control becomes possible, but the physical change in strap tension is not easily recognizable by the player
Solution Approach 1:
A generator is introduced as an intermediary mechanism between the strap tension and the detection system. The generator converts the linear tension movement into rotational movement, which is then detected by a rotation detection device. This intermediary conversion makes the invisible tension change visible and recognizable through rotational motion that players can easily perceive and control.
Solution Approach 2:
The patent replaces the direct linear extension detection with a rotational detection system. By substituting the mechanical detection method from measuring linear extension to measuring rotation, the system achieves better recognizability. The rotation detection device provides clearer feedback to the player about the tension applied, improving ease of operation while maintaining automated control.
2Ease of operation
If a rotation detection device is used to detect tension changes, then recognizability improves, but device complexity increases
Solution Approach 1:
The generator serves as a compact intermediary that efficiently converts linear motion to rotational motion using well-established electromagnetic principles. This approach adds minimal complexity compared to designing a completely new detection system, as generators are standard components with predictable behavior and straightforward integration.
Solution Approach 2:
The patent changes the detection parameter from linear extension to rotational movement. This parameter transformation simplifies the detection mechanism by using rotation, which is naturally more detectable and provides better feedback. The generator enables this parameter change while maintaining a relatively simple overall system structure through its straightforward mechanical-coupling design.
