Motorized Drum Tuning Device for Precise Bolt Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum tuning is time-consuming and prone to human error due to the need for manual adjustment of bolt tension and rotation, especially when dealing with multiple bolts and uneven skin tension, and requires significant dexterity and effort.
Innovation Solution
A drum tuning device featuring a drive head with a motor and control means that allows precise, pre-settable rotation of drum skin tension control bolts to specific angles, reducing manual effort and ensuring even tension across the drum skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual keys are used to tighten bolts, then tuning can be performed, but it is time-consuming and prone to human error due to difficulty in gauging rotation angle by eye
Solution Approach 1:
The patent replaces manual mechanical key operation with an automated motor-driven system. The motor rotates the bolt through a precisely controlled angle determined by control means, eliminating the need for manual angle gauging by eye and ensuring consistent, accurate rotation for each bolt.
Solution Approach 2:
The tuning device performs the tuning operation automatically without requiring skilled manual intervention. The system self-regulates the rotation angle through its control mechanism, making the process independent of operator skill and significantly reducing tuning time while maintaining precision.
2Stability of the object's composition
If multiple bolts are used around drum hoop periphery, then even tension can be achieved, but the tuning process becomes more time-consuming due to the large number of bolts
Solution Approach 1:
The automated device independently adjusts each bolt with precise rotational control, ensuring even tension distribution across all bolts without requiring manual intervention for each one. This automation maintains tension uniformity while dramatically increasing tuning speed compared to manual methods.
3Ease of operation
If ratchet devices are used in keys, then slipping in one direction is allowed, but it is difficult to gauge the amount of rotation applied to each bolt
Solution Approach 1:
The patent replaces the ratchet mechanism with a motor-driven system that provides both ease of operation and precise rotation control. The motor can rotate the bolt in the tightening direction without requiring ratchet slipping, while the control means ensures accurate rotation angle measurement and consistency.
4Stability of the object's composition
If minimal tension is applied to each bolt first, then even tensioning can be achieved, but significant physical effort is required on the wrist and fingers during manual tuning
Solution Approach 1:
The patent replaces manual key operation with a motor-driven system that eliminates physical strain on the operator's wrist and fingers. The motor provides the necessary torque to tighten bolts from minimal tension to final tension, while the control means ensures even rotation angles for uniform skin tensioning.

AI summary
A drum tuning device (10) comprises a drive head (14) adapted to engage a head of a drum skin tension control device, a motor (24, see FIG. 6) for rotating the drive head and control means for controlling rotation of the drive head. The control means includes three push buttons (16,18,20), which each control rotation of the drive head (14) to different pre-selectable angles of rotation.
