Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum-type musical instruments have single functions, leading to poor market competitiveness and an inability to meet market demands for multi-functional instruments.
Innovation Solution
A three-in-one drum design featuring a drum chamber, drum skin, pressing rings, a vertically adjustable beating tray with a cushion, an annular beating trigger connected to an electronic sound source, and a microphone vibrator, allowing for adjustable height and switching between mute, electric drum, and raw sound drum functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional drum-type musical instruments are used, then the structure is simple, but the function is single and market competitiveness is poor
Solution Approach 1:
The patent applies multi-functionality by integrating three distinct drum functions (raw sound drum, mute drum, and electric drum) into a single instrument. The beating tray can be adjusted to different positions: when lowered, it allows raw sound drum function; when raised, it enables mute drum function by isolating the drum skin from the tray; and when in intermediate position, it activates the beating trigger for electric drum function. This resolves the contradiction by providing multiple functions without requiring multiple separate instruments.
Solution Approach 2:
The patent employs dynamics through the adjustable beating tray mechanism. The tray can be dynamically positioned at different heights using an adjusting rod with threading, allowing the instrument to switch between different functional states. This dynamic adjustment capability enables the same physical structure to serve multiple purposes, resolving the contradiction between simplicity and versatility.
2Adaptability or versatility
If the beating tray is raised for mute drum function, then the drum skin does not ground when beaten, but the adjusting mechanism increases device complexity
Solution Approach 1:
The adjusting mechanism is segmented into modular components including the adjusting rod with external screw threads, sliding thread bases, and guide holes in the inner sliding sleeves. This segmentation allows each component to perform a specific function while maintaining overall simplicity. The threaded adjustment mechanism provides precise control over the beating tray position, enabling mute drum function without excessive complexity.
3Adaptability or versatility
If the beating tray is lowered for raw sound drum function, then the drum skin sounds when beaten, but the cushion contact may cause unwanted damping
Solution Approach 1:
The beating tray's dynamic positioning allows it to be lowered close to the drum skin for raw sound drum function. The cushion on the tray provides minimal contact damping while still allowing the drum skin to vibrate freely and produce natural sounds. The adjustability ensures optimal positioning that balances sound quality with the cushion's presence, resolving the contradiction between maintaining raw sound function and managing cushion damping effects.
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
Enables versatile functionality by allowing the drum to operate in mute, electric drum, and raw sound modes, enhancing market competitiveness and user flexibility.
Implementation Method 1
The bottom of the beating tray is provided with a microphone vibrator which is externally connected to a loudspeaker box
Implementation Method 2
The adjusting rod has a segment of external screw threads on each of the left and right ends

AI summary
A three-in-one drum includes a drum chamber, a drum skin and pressing rings. A beating tray is vertically and adjustably disposed in the drum chamber and covered with a cushion. The bottom of the beating tray has a microphone vibrator connected to a loudspeaker box. When the adjusting rod is rotated clockwise, the beating tray rises and the cushion is close to the drum skin. The drum skin does not ground when being beaten, this is the mute drum function. An beating trigger connected with an electronic sound source sends electronic signal to perform the electric drum function. The microphone vibrator amplifies the audio frequency signal to perform the audio amplification function. When the adjusting rod is rotated counter clockwise, the beating tray is lowered and the cushion is located away from the drum skin which sounds when being beaten to perform the raw sound drum function.
