Pedal Device With Alternative Detection Means For Electronic Percussion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedal devices for electronic percussion instruments, such as those simulating hi-hat and bass drum, often have different detection mechanisms, leading to varying detection accuracy and operational feelings, and lack part commonality, making them less versatile and efficient.
Innovation Solution
A pedal device with a base that supports a pedal with a pressing part away from the rotation shaft, featuring alternative detection means on different portions to ensure accurate rotation detection and operational feel adjustment, allowing for use in both hi-hat and bass drum simulations with reduced production costs and improved operational experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first sensor is disposed closer to the rotation shaft than the coil spring, then the pedal device can be used for hi-hat simulation, but the detection accuracy of pedal rotation is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the detection means selectable rather than fixed. The pedal device can dynamically switch between using the first detection means (closer to rotation shaft for hi-hat) and the second detection means (farther from rotation shaft for bass drum), allowing the system to adapt its detection configuration based on the specific application requirements.
Solution Approach 2:
The patent changes the positional parameter of the detection means relative to the rotation shaft. By providing two different detection means at different distances from the rotation shaft, the system can select the appropriate detection means based on whether it's used for hi-hat or bass drum simulation, thereby optimizing detection accuracy for each specific application.
2Measurement precision
If different pedal devices with different detection means structures are used for hi-hat and bass drum simulations, then each instrument can have optimized detection accuracy, but part commonality is lost and production costs increase
Solution Approach 1:
The patent applies the universality principle by designing a single pedal device that can serve multiple functions - both hi-hat simulation and bass drum simulation. The pedal device includes both the first detection means and the second detection means, allowing it to be universally applied to different electronic percussion instruments depending on which detection means is selected and activated.
Solution Approach 2:
The patent makes the pedal device dynamically configurable by allowing selection between different detection means. This dynamic capability enables the same physical pedal device to adapt to different instrument types (hi-hat or bass drum), achieving versatility without requiring separate dedicated devices for each application.
3Measurement precision
If the pressing part is disposed away from the rotation shaft, then the displacement range increases for better detection accuracy, but the structural complexity increases
Solution Approach 1:
The patent applies segmentation by separating the detection function into two distinct detection means positioned at different locations. The first detection means is positioned closer to the rotation shaft while the second detection means is positioned farther away, allowing each to serve specific detection purposes without requiring a single complex detection system.

AI summary
A pedal device for an electronic percussion instrument is provided, wherein first and second detection means for detecting a rotation of a pedal by different methods are alternatively disposed in a base. The pedal has a pressing part on a lower surface side. The base includes a first portion located under the pressing part for supporting the first detection means, and a second portion located around the first portion for supporting the second detection means. The first portion supports the first detection means such that a first pressed part of the first detection means is disposed on a displacement trajectory of the pressing part that displaces with the rotation of the pedal, and the second portion disposes the second detection means such that a second pressed part of the second detection means is disposed on the displacement trajectory of the pressing part.
