High Hat Stand Assembly Normally Closed Position Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional high hat devices typically maintain a normally open position, whereas the new design aims to retain a high hat in a normally closed position, addressing the need for a device that can switch between closed and open positions efficiently.
Innovation Solution
The design features a lower cylinder on a drum kit pedal with a middle cylinder extending upwardly, a top cylinder slidably positioned on the middle cylinder, and a high hat rod coupled to the middle cylinder, where a biasing member keeps the top cymbal pressed against the bottom cymbal, and a lowering unit actuates to space the cymbals, allowing the high hat to be opened by stepping on the pedal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional high hat devices are designed to maintain a normally open position, then the device structure is simple, but the operational functionality is limited and does not meet the need for normally closed position retention
Solution Approach 1:
The device is divided into three separate cylinders (lower, middle, and top) that can move independently relative to each other. This segmentation allows each cylinder to perform specific functions: the lower cylinder provides structural support, the middle cylinder moves vertically to control cymbal positioning, and the top cylinder houses the lowering unit. This modular approach enables normally closed position retention while managing complexity through functional division.
Solution Approach 2:
The top cylinder is nested within the middle cylinder, which itself is nested within the lower cylinder assembly. This nested configuration allows the top cylinder to slide vertically along the middle cylinder, creating a compact structure that achieves normally closed position retention without requiring excessive space or structural complexity.
2Adaptability or versatility
If a biasing member is used to keep the top cymbal pressed against the bottom cymbal, then the high hat remains in normally closed position, but the mechanism requires additional components to achieve opening action
Solution Approach 1:
Instead of using a traditional spring-loaded mechanism that pushes the cymbals apart (normally open), this invention inverts the approach by using a biasing member that pushes the cymbals together (normally closed). The lowering unit then acts to release this biasing force, allowing gravity and the biasing member to close the cymbals automatically when not in use, achieving normally closed position retention.
Solution Approach 2:
The biasing member automatically maintains the cymbals in the closed position without requiring continuous external force or power. When the lowering unit is actuated, it releases the constraint, and the biasing member naturally returns the cymbals to their closed position, enabling the system to self-regulate its state.
3Ease of operation
If the top cylinder is made slidable on the middle cylinder, then the high hat can switch between open and closed positions, but the structural stability may be compromised
Solution Approach 1:
The top cylinder is designed to slide vertically along the middle cylinder, transforming the static structure into a dynamic one. This sliding mechanism allows the top cylinder to move up and down in response to pedal actuation, enabling the high hat to switch between open and closed positions while maintaining structural integrity through guided motion constraints.
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
This configuration allows the high hat to be easily switched between normally closed and open positions, reversing the action of traditional high hat stands, enabling efficient operation by altering the positioning of the cymbals based on pedal activation.
Implementation Method 1
The top cylinder is biased upwardly on the middle cylinder
Implementation Method 2
The lowering unit urges the top cylinder downwardly on the middle cylinder when the lowering unit is actuated

AI summary
A high hat stand assembly includes a lower cylinder that is positioned on a high hat pedal of a drum kit. A middle cylinder extends upwardly from the lower cylinder and a top cylinder is slidably positioned on the middle cylinder. The top cylinder is biased upwardly on the middle cylinder. A high hat rod is coupled to and extends upwardly from the middle cylinder. A bottom cymbal of a high hat is fixed to the top cylinder and a top cymbal of the high hat is fixed to the high hat rod. A lowering unit is movably integrated between the lower cylinder, the middle cylinder and the top cylinder. The lowering unit urges the top cylinder downwardly on the middle cylinder when the lowering unit is actuated such that the bottom cymbal is spaced from the top cymbal.
