Fast-Dismounted Cymbal-Locking Nut With Pivoting Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cymbal-locking nut assemblies are laborious and time-consuming for mounting or dismounting cymbals due to the need for slow rotation of the locking head and hindered operation of altitude adjusting rings by the cymbal.
Innovation Solution
A fast-dismounted cymbal-locking nut with a seat, first wing, second wing, and resilience element, featuring semi-spherical threaded grooves that pivot between locking and fast-dismount positions, allowing direct mounting and dismounting without slow screwing, and securely gripping the cymbal when locked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional locking head is screwed through the mounting bolt to fasten the cymbal, then the cymbal can be securely held, but the user has to slowly rotate the locking head many cycles to mount or dismount the cymbal, making the operation laborious and time-consuming
Solution Approach 1:
The locking nut is segmented into a body and two separate wings that can pivot independently. The wings can be positioned at a fast-dismount angle to allow quick removal or a locking angle to secure the cymbal, enabling rapid transition between states without multiple rotation cycles
Solution Approach 2:
The wings are designed to pivot between different angular positions (fast-dismount angle and locking angle) rather than requiring rotational threading. This dynamic positioning allows the user to quickly switch between locked and unlocked states by simply pivoting the wings, dramatically reducing the time and effort required for mounting and dismounting
2Adaptability or versatility
If an altitude adjusting ring is placed below the cymbal to allow altitude adjustment, then the cymbal can be adjusted to different heights, but the cymbal hinders the user from operating the altitude adjusting ring, making it inconvenient
Solution Approach 1:
The altitude adjusting ring is repositioned from below the cymbal to above the cymbal. This spatial repositioning in another dimension allows the user to access and operate the altitude adjustment mechanism without the cymbal blocking the path, improving ease of operation while maintaining full altitude adjustment functionality
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 fast and convenient mounting or dismounting of cymbals by allowing direct transition between locking and fast-dismount positions, reducing operational labor and improving accessibility to altitude adjustments.
Implementation Method 1
The resilience element is used to force the first wing and the second wing to respectively move from their fast-dismount positions toward their locking positions and maintain the first wing and the second wing to be normally at their locking positions

AI summary
A fast-dismounted cymbal-locking nut being screwed through an outer thread of a mounting bolt of a cymbal to press the cymbal tightly and adjust the position of the cymbal, comprises a seat, a first wing, a second wing, and a resilience element. The first and second wings are pivotally coupled to the seat; each of them has a locking position and a fast-dismount position. The first and second wings respectively include first and second semi-spherical threaded grooves, which jointly form an inner thread corresponding to the outer thread at their locking positions. At the fast-dismount positions, the shortest distance between the first and second semi-spherical threaded grooves is larger than the outer diameter of the outer thread. The user can directly mount the nut to the outer thread without screwing the nut through the outer thread. The nut enables the user to fast mount or dismount a cymbal.
