Ocean Drum with Segmented Membranes and Phosphorescent Balls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ocean drums with two vibratile membranes lack versatility in sound production and visual appeal, as they do not offer sufficient variation in sound nuances or visual effects, limiting their use in music and relaxation applications.
Innovation Solution
The ocean drum is enhanced with three vibratile membranes and a series of rings with phosphorescent balls of different materials and diameters, allowing for varied sound production and enhanced visual effects by using laminated plywood or solid wood rings without joints, and employing a unique gluing method with holes and nails for improved adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three vibratile membranes are added instead of two, then sound production versatility is improved, but device complexity increases
Solution Approach 1:
The drum body is divided into multiple compartments by adding intermediate rings that hold additional membranes. This segmentation allows independent sound production from each membrane compartment while maintaining overall structural organization. The three membranes are separated into distinct sections, each capable of producing different sound nuances when tilted.
Solution Approach 2:
Multiple membranes are nested within the same drum body structure, with intermediate rings containing additional membranes inside the main drum cavity. This nesting approach allows three membranes to coexist in a compact form factor, increasing versatility without proportionally increasing the external dimensions of the instrument.
2Adaptability or versatility
If phosphorescent balls of different materials and diameters are inserted, then visual effects and sound nuances are improved, but manufacturing complexity increases
Solution Approach 1:
Different balls with varying materials, diameters, and phosphorescent properties are placed in different compartments or regions within the drum. This local differentiation allows each ball to contribute specific sound characteristics and visual effects, creating a diverse auditory and visual experience without requiring all balls to be identical.
Solution Approach 2:
The instrument incorporates balls made from different materials (including phosphorescent materials) to achieve varied acoustic and visual properties. This use of composite and diverse materials allows for rich sound production and enhanced visual effects, particularly in low-light conditions where phosphorescence is visible.
3Strength
If rings are made as single undivided pieces, then structural integrity is improved, but manufacturing difficulty increases
Solution Approach 1:
The intermediate rings are constructed from laminated plywood or flexible composite materials that can be formed into continuous circumferential structures. These thin-film-like flexible materials allow the rings to be manufactured as single pieces with good structural integrity while remaining workable during the manufacturing process.
Solution Approach 2:
Laminated plywood and composite materials are used to construct the rings, providing both structural strength and manufacturability. These composite materials can be layered and formed into continuous rings that maintain integrity while being feasible to produce using standard woodworking and composite fabrication techniques.
4Strength
If a unique gluing method with holes and nails is employed, then adhesion strength is improved, but manufacturing steps increase
Solution Approach 1:
Holes are pre-drilled into the rings and membranes at designated locations before the gluing process. This preliminary action prepares the components for the nail-glue assembly method, ensuring proper alignment and positioning. The pre-drilled holes guide the placement of adhesive nails, making the subsequent assembly more efficient and reliable.
Solution Approach 2:
The adhesive nails serve a dual function: they provide mechanical fastening through the holes while also anchoring the adhesive material. This self-service approach, where the fastening elements simultaneously perform both mechanical and adhesive functions, simplifies the overall assembly process despite the multiple steps involved, as the same structural features serve multiple purposes.

Function Achieved in This Case
The enhanced ocean drum produces a richer range of sea wave sounds and visual effects, offering improved musical and relaxation experiences through varied sound nuances and enhanced visual appeal, suitable for musical performances, therapy, and children's activities.
Implementation Method 1
some balls of different materials and diameters, phosphorescent as well, are inserted in the cylindrical compartments or interspaces
Implementation Method 2
the polymer film returns to the original condition firmly fixed to the body of the instrument, and it is sufficiently tensioned in order to generate sound if subjected to percussion

AI summary
Musical instrument of the type called “ocean drum” provided with three or more vibratile membranes, in the interspaces of which some balls of different materials and diameters, phosphorescent as well, are inserted. By tilting said drum, provided with two or more planes bearing some balls, the latter roll on the internal surface of the membranes produces sounds that evoke sea waves. Said “ocean drum” has a plurality of rings with a common central axis, aligned in a fixed way to enable the insertion of three or more vibratile membranes between them. Said rings are made of laminated plywood, solid wood or plastic material. They are glued, without discontinuity, to the circular membranes made of animal leather, or of polymer films provided with holes on a median diameter of the rings for more resistant gluing.
