Stepless Cymbal Mount with Friction Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cymbal locating structures fail to provide fine adjustments in both vertical and horizontal orientations, limiting the ability to achieve precise angular positions, and require cumbersome adjustments to change horizontal orientations.
Innovation Solution
A steplessly adjustable cymbal locating device with a housing, rotating mechanism, and adjustable locking subassembly allows for fine adjustments in two axis directions, using friction ring washers and a threaded bolt and nut for secure and adjustable positioning, enabling precise vertical and horizontal adjustments without the need for tooth-socket engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tooth-socket engagement design is used for angle adjustment, then the cymbal locating rod can be set to different vertical angles, but the adjustment precision is limited by the number and density of locating teeth and tooth sockets
Solution Approach 1:
The patent replaces the conventional tooth-socket engagement mechanism with a friction-based locking system. The clamp disc assembly uses friction between the clamp disc and friction ring washer to hold the cymbal locating rod at any desired angle, eliminating the need for multiple discrete locating teeth and tooth sockets. This substitution enables continuous (stepless) adjustment while reducing structural complexity.
Solution Approach 2:
The patent introduces a dynamic adjustment mechanism where the clamp disc can be freely rotated during adjustment and then locked at any position using the friction-based locking system. The adjustable locking mechanism allows the system to transition between a free state (for adjustment) and a locked state (for positioning), enabling stepless angular adjustment without predefined discrete positions.
2Ease of operation
If conventional cymbal locating structure is used, then the structure is simple, but the cymbal cannot be adjusted in horizontal orientation without lifting and turning the whole stand
Solution Approach 1:
The patent divides the adjustment function into two independent segments: vertical angle adjustment and horizontal orientation adjustment. The clamp disc assembly handles vertical angle adjustment while the rotatable housing assembly handles horizontal orientation adjustment. This segmentation allows each direction to be adjusted independently without affecting the other, eliminating the need to lift and reposition the entire stand.
Solution Approach 2:
The patent adds a horizontal rotation dimension to the conventional vertical adjustment system. The housing can rotate horizontally relative to the stand pole, while the clamp disc assembly provides vertical angle adjustment. This dimensional expansion enables two-degree-of-freedom adjustment (vertical and horizontal) without increasing the complexity of the overall structure.
3Ease of operation
If friction-based stepless adjustment is used, then fine adjustment is enabled, but the components may become loose and the cymbal may fall without adequate locking
Solution Approach 1:
The patent introduces friction ring washers as intermediary elements between the clamp disc and the housing. These washers provide the necessary friction for locking while allowing for fine adjustment. The friction-based interaction acts as a mediator that enables both smooth adjustment and reliable holding, preventing the components from becoming loose while maintaining stepless adjustability.
Solution Approach 2:
The patent utilizes friction as a controllable parameter to achieve both fine adjustment and reliable locking. By designing the friction interface between the clamp disc and friction ring washer with appropriate contact pressure and surface properties, the system can transition smoothly during adjustment and then maintain a stable locked position. The friction parameter is optimized to provide sufficient holding force without preventing fine adjustments.

AI summary
A steplessly adjustable cymbal locating device includes a housing having a first receiving space and a notch; a rotating mechanism having a second receiving space and being clamped in the first receiving space with the housing vertically rotatable relative to the rotating mechanism; a rotating pole partially clamped in the second receiving space with the rotating mechanism horizontally rotatable relative thereto; a fixed pole fixedly assembled to one side of the housing; and an adjustable locking subassembly extended into the housing and the rotating mechanism for selectively pressing the housing, the rotating mechanism and the rotating pole against one another to an immovably state or loosening them from one another to allow stepless adjustment of the locating device in two axis directions. Thus, a cymbal mounted on either the rotating or the fixed pole can be adjusted to any horizontal orientation and vertical angle according to a user's need.
