High Hat Tambourine Quick-Release Hub
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high hat tambourine accessories require two hands to mount or remove due to the need for screw wing nuts, disrupting continuous percussion and being inconvenient for drummers who need to instantly change sounds.
Innovation Solution
A high hat tambourine assembly with a quick-release mechanism that allows single-handed mounting and removal, featuring a circular ring with inwardly curved cross members and manually actuatable quick-release arms that frictionally engage a pull rod, eliminating the need for separate hardware like wing nuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw wing nuts are used to mount the tambourine on the pull rod, then the mounting is secure and reliable, but the mounting and removal process requires two hands and interrupts continuous percussion
Solution Approach 1:
The patent applies a dynamic quick-release mechanism where spring-loaded arms with friction surfaces can rapidly transition between engaged and disengaged states. The spring arms normally engage the pull rod through friction, providing secure mounting, but can be quickly released by applying lateral force to the release tabs, enabling single-handed operation without interrupting performance.
Solution Approach 2:
The friction-based quick-release mechanism allows the tambourine to self-secure on the pull rod through spring pressure, eliminating the need for separate fastening actions. The device maintains its own secure connection through continuous spring force against the rod, while allowing rapid release when needed.
2Reliability
If wing nuts are used for mounting, then the connection is stable, but the operation requires multiple turns and both hands, reducing productivity
Solution Approach 1:
The spring-loaded arms provide continuous dynamic pressure against the pull rod, maintaining stable connection without requiring multiple tightening turns. The spring force automatically adjusts to maintain optimal friction engagement, enabling rapid mounting and removal in a single motion rather than multiple rotational turns.
Solution Approach 2:
The patent replaces the traditional threaded mechanical fastening system with a friction-based spring arm mechanism. This substitution eliminates the need for threading and rotational tightening, allowing the tambourine to be quickly secured and released through simple linear engagement and disengagement motions.
3Ease of operation
If a quick-release mechanism is used, then single-handed operation is enabled, but the mechanism must withstand significant downward pressures and striking forces
Solution Approach 1:
The spring-loaded arms dynamically adjust their engagement force with the pull rod, maintaining sufficient friction to resist downward pressures and striking forces during normal operation. When release is needed, lateral force on the tabs overcomes the spring pressure, allowing quick disengagement. This dynamic system handles both high force resistance and easy release requirements.
Solution Approach 2:
The patent combines the mounting function, securing function, and release function into a single integrated quick-release mechanism. The spring arms simultaneously provide secure mounting through friction, resist operational forces, and enable rapid release through tab actuation, merging multiple functions into one unified system that handles both strength and ease of operation requirements.
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 quick and convenient single-handed operation, ensuring the tambourine can withstand significant downward pressures and striking forces without slippage, allowing drummers to maintain uninterrupted performance.
Implementation Method 1
manually actuatable quick-release arms mounted on the hub for pivoting action and which are normally biased to provide a lower opening that is generally smaller than an elongate axial channel through the hub. A pull rod of the high hat extends through the axial channel with some tolerance for allowing free slideable movements between the rod and the hub. The lower opening formed by the release arms, being restricted in size, engages the rod and provide gripping members that frictionally engage the rod with a force sufficient to secure the hub and the ring to the pull rod to prevent slipping notwithstanding any downward striking forces applied to the ring.

AI summary
A high hat tambourine assembly includes a circular frame and a hub coextensive with the frame axis and has an elongate axial channel dimensioned to receive a rod of a high hat for free relative slidable movements. Quick-release arms are mounted on the hub and normally biased to provide an opening that is smaller than axial channel and having manually engageable gripping members that frictionally engage the rod with a force sufficient to normally secure said hub to the rod. The arms can be manually gripped by the hand of the user and actuated to separate the gripping members to enlarge the normally restricted opening to allow the rod to freely pass. A plurality of jingles are secured to the frame. The high hat tambourine assembly can be quickly and conveniently mounted on or released from the rod with one hand of the user.
