Rotating Buffer Drum Hanger for Adjustable Sustain Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drum hangers fail to provide adjustable control over the shaking and sustain levels, limiting musical expression to different music styles.
Innovation Solution
A drum hanger with a holder and buffer system that allows for adjustable sustain control through a rotating buffer with varying distances from the drum side, enabling multiple stages of sustain adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buffer is fixed against the drum side to eliminate sustain, then the drum shaking is suppressed, but the ability to adjust shaking levels for different music styles is lost
Solution Approach 1:
The buffer is designed to be rotatable around the shaft, transforming a static structure into a dynamic one. This allows the buffer to switch between different positions (contacting and non-contacting the drum side), enabling the user to adjust the shaking level according to different music styles while maintaining reliable sustain control when needed
2Adaptability or versatility
If the rubber is positioned away from the drum side to allow normal shaking, then complete sustain is achieved, but the ability to suppress shaking when needed is lost
Solution Approach 1:
The rotatable buffer mechanism allows dynamic switching between two states: when the buffer rotates to contact the drum side, it suppresses shaking and eliminates sustain; when it rotates away, the drum shakes normally with complete sustain. This dynamic design provides both shaking control flexibility and reliable sustain suppression capability
3Device complexity
If a simple rubber piece is used to suppress drum shaking, then the structure is simple, but the control over sustain levels is binary and non-adjustable
Solution Approach 1:
By making the buffer rotatable around the shaft, the invention adds minimal structural complexity (a rotation mechanism) to achieve multi-level sustain control. The buffer can be positioned at different angles to create different distances from the drum side, providing adjustable sustain levels while maintaining overall structural simplicity
4Reliability
If the buffer contacts the drum side with maximum force to eliminate sustain, then sustain is completely eliminated, but the ability to produce partial sustain for certain music styles is lost
Solution Approach 1:
The buffer is designed with asymmetric positioning relative to the shaft, with different sides at different distances from the shaft. This asymmetry allows the buffer to contact the drum side at varying distances, creating different levels of pressing force. When a side closer to the shaft contacts the drum, it exerts maximum force to eliminate sustain; when a side farther from the shaft contacts, it exerts less force to produce partial sustain, providing adaptability for different music styles

AI summary
A drum hanger can fix a drum and has a holder and a buffer. The holder is mounted on the drum side and has a shaft. The buffer is mounted on the holder. The shaft is mounted through the buffer and the buffer can rotate with the shaft as an axis. The buffer has multiple sides, and distances from the respective sides to the shaft are different from one another. When each side faces toward the drum side respectively, the force of the buffer against the drum side differs. When the buffer does not contact the drum side, the drum can shake normally. The greater the force of the buffer against the drum side, the smaller the shaking of the drum. Therefore, the user can rotate the buffer around the shaft as the axis, to control the distance between the buffer and the drum side, thereby adjusting the shaking of the drum.
