Pivot Supports for Drum Rim Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drum beating apparatus face challenges in stabilizing connections between bass drum rims and beaters, particularly due to the heavy weight and size of bass drums, leading to disconnection issues during extended use periods, necessitating a reliable and efficient connection mechanism.
Innovation Solution
A drum beating assembly comprising a frame with a pedestal, an axle, a drum beater, a pedal, and multiple self-adjusting drum rim support elements that engage the drum rim at multiple locations, including convex and concave sides, to provide stable and balanced clamping force distribution, utilizing toggle support for universal directional pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple connection mechanism is used, then device complexity is reduced, but reliability deteriorates due to disconnection under heavy drum weight
Solution Approach 1:
The connection mechanism incorporates multiple pivotally adjustable support elements that can dynamically adapt their position and orientation. These elements include a first support element pivotally connected to the base plate, a second support element pivotally connected to the first, and a third support element pivotally connected to the second, creating a kinetic chain that can self-adjust during drum beating operations
Solution Approach 2:
The patent combines multiple support elements into an integrated clamping mechanism that engages the drum rim at multiple locations simultaneously. The support elements work together as a unified system, with the clamp arm integrating the pivotal support elements and providing combined clamping action across the drum rim, thereby achieving reliable connection without excessive complexity
2Reliability
If multiple support elements are used to engage the drum rim at multiple locations, then reliability is improved, but device complexity increases
Solution Approach 1:
The connection mechanism is segmented into distinct pivotal support elements that can independently engage different locations on the drum rim. This segmentation allows each element to be optimized for its specific engagement point while working together as part of the overall clamping system
Solution Approach 2:
The pivotal support elements serve multiple functions: they provide structural support, enable self-adjustment to drum rim variations, distribute clamping forces, and accommodate different drum sizes and configurations. This multi-functionality reduces the need for additional specialized components
3Adaptability or versatility
If pivotally adjustable support elements are used, then adaptability is improved for self-adjustment, but device complexity increases
Solution Approach 1:
The pivotal support elements are designed to automatically self-adjust during drum beating operations without requiring external control or complex actuation mechanisms. The pivotal connections allow the elements to naturally conform to the drum rim geometry and distribute forces as the drum is beaten, providing self-adjustment through the inherent mechanics of the connection

AI summary
In a drum beating assembly, the combination comprising a frame, including at least one pedestal, an axle carried by the pedestal to rotate relative thereto, the axle having an axis of rotation, a drum beater carried by the axle, a pedal operatively connected to the axle to rotate the axle and beater in response to pedal movement, the frame including a base plate, there being a clamp arm and means supporting the arm on the plate to pivot relative thereto, and multiple drum rim support elements carried to engage the drum rim at multiple locations to support the drum rim relative to the base plate. The support elements are typically pivotable to self-adjust during clamp up.
