Low Volume Drumhead With Elastic Polymer Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mesh drumheads reduce volume but compromise on sound quality and feel, failing to meet the sonic expectations of professional musicians.
Innovation Solution
A low volume drumhead is created by adding mass to a mesh drumhead using materials like resin, MYLAR, or fiberglass, which are affixed to the mesh surface using elastic polymers, restoring sonic quality and feel while maintaining lower volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a mesh drumhead is used to reduce volume, then the volume is lowered, but the sound quality and feel deteriorate
Solution Approach 1:
The drumhead combines a mesh layer with a non-mesh layer (such as Mylar, fiberglass, or resin) to create a composite structure. The mesh layer provides the low-volume characteristic by allowing less energy transmission, while the non-mesh layer restores the traditional drumhead feel and sound quality by providing a solid beatable surface that responds appropriately to drumstick strikes.
Solution Approach 2:
The non-mesh layer is applied selectively to specific areas of the mesh drumhead, particularly the central beatable area where drumsticks make contact. This localized application ensures that the sound quality and feel are improved in the critical striking zone while maintaining the low-volume特性 of the mesh layer in other areas.
2Reliability
If mass is added to a mesh drumhead to restore sound quality, then the sonic quality improves, but the volume increases
Solution Approach 1:
Mass is added only to the central beatable area of the mesh drumhead where drumsticks strike, rather than uniformly across the entire surface. This localized mass addition improves the sonic quality and feel in the critical striking zone while minimizing the increase in overall volume, as the mesh layer in the outer areas continues to provide volume reduction.
Solution Approach 2:
The combination of mesh material with non-mesh materials (Mylar, fiberglass, resin) creates a composite structure where each material contributes its advantageous properties. The mesh provides volume reduction, while the non-mesh components provide the necessary mass for improved sound quality without requiring uniform mass distribution across the entire drumhead.
3Strength
If adhesive is used to couple the mesh layer to the non-mesh layer, then the layers are bonded, but adhesive failure may occur under tension
Solution Approach 1:
The adhesive properties are specifically optimized for the application conditions, including selecting adhesives with appropriate elasticity, open time, and ultimate bond strength. The adhesive formulation is designed to accommodate the tension and stretching that occurs during drumhead installation and tuning, preventing adhesive failure while maintaining reliable bonding between the mesh and non-mesh layers.
Solution Approach 2:
The adhesive acts as an intermediary material that bridges the mesh layer and non-mesh layer, providing a flexible bond that can accommodate differential movement and tension between the two layers. The adhesive's elastic properties allow it to stretch and flex without failing, maintaining the integrity of the composite structure under various playing and environmental conditions.
