Electronic Percussion Support Member Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic percussion instruments suffer from floor reverberation and reduced durability due to direct transmission of impact forces, degrading sound quality and durability.
Innovation Solution
An electronic percussion instrument design featuring a support member with a bent shape, where the pad-attaching portion deflects rearward relative to the stand-attaching portion, absorbing impact and reducing floor reverberation, while maintaining sound quality and durability without increasing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the head is firmly fixed to the stand with a rigid support structure, then the structural stability is improved, but the impact force is directly transmitted to the floor causing floor reverberation and degrading sound quality
Solution Approach 1:
The support member is designed with flexibility to allow controlled deflection during impact, absorbing shock while maintaining structural integrity. The bent shape with inflection point creates a flexible connection that prevents rigid force transmission to the floor.
Solution Approach 2:
The support member's geometric parameters are optimized by positioning the inflection point at the front end of the stand-attaching portion, allowing controlled deflection behavior that absorbs impact energy without compromising structural stability.
2Stability of the object's composition
If the head is firmly fixed to the stand with a rigid support structure, then the structural stability is improved, but the large impact force is instantaneously applied to constituent elements degrading the durability
Solution Approach 1:
The flexible support member with bent shape and inflection point allows controlled deflection that absorbs impact energy, preventing instantaneous large forces from being applied to constituent elements while maintaining structural stability.
3Ease of manufacture
If a rigid support structure is used to firmly fix the head, then the manufacturing simplicity is improved, but the floor reverberation degrades the sound quality
Solution Approach 1:
The support member is designed as a bent shape with inflection point that can be manufactured as a single integrated piece, maintaining manufacturing simplicity while introducing flexibility to suppress floor reverberation through controlled deflection.
Solution Approach 2:
The bent shape of the support member with inflection point introduces curvature that enables flexible deflection behavior, absorbing impact energy and preventing floor reverberation while remaining manufacturable as a simple formed structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively suppresses floor reverberation, enhances sound quality, and improves durability by absorbing impact through deflection, maintaining sound quality and reducing noise, while maintaining the instrument's appearance and manufacturability.
Implementation Method 1
the pad-attaching portion is deflected about the inflection point in the rearward direction relative to the stand-attaching portion due to a striking operation which is applied to the head

AI summary
An electronic percussion instrument includes a stand, a support member (e.g. a stay), a pad member with a head, and an impact sensor. The support member has an L-shape including a stand-attaching portion and a pad-attaching portion. The stand-attaching portion is fixed to the stand while the pad-attaching portion is extended vertically from the front end of the stand-attaching portion at an inflection point. Owing to the elasticity of the support member, the pad-attaching portion is deflected about the inflection point in the rearward direction in comparison with the stand-attaching portion due to a striking force applied to the head being struck with a beater. Upon detecting an impact applied to the head, the impact sensor generates an electric signal so as to generate a musical sound. Thus, it is possible to suppress floor reverberation by absorbing an impact between the head and the beater via the support member.
