Pedal Beating Apparatus Seesaw Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pedal beating apparatuses for drums are tedious and time-consuming due to the need for manual screwing to clamp drum hoops, which fails to meet usability and convenience requirements.
Innovation Solution
A pedal beating apparatus with a pedal beating holder, elevation adjustment tray, and clamp beam, featuring a fulcrum member, compression spring, and adjustable clamp mechanism that forms a seesaw structure to quickly clamp drum hoops of varying thicknesses using a movable elevation adjustment tray and clamp beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual screwing is used to clamp drum hoops, then the clamping structure is simple, but the operation becomes tedious and time-consuming
Solution Approach 1:
The drum hoop clamping mechanism uses self-service principle where the drum hoop itself serves as the lever arm. When the drum hoop is inserted, its weight and position automatically activate the seesaw mechanism to drive the clamp beam, eliminating the need for manual screwing operations while achieving rapid clamping and release
Solution Approach 2:
The patent transforms the static screw clamping system into a dynamic seesaw mechanism. The clamp beam is designed to rotate around a fulcrum point, creating a dynamic lever system that automatically adjusts and locks the drum hoop in position through controlled motion rather than static fastening
2Adaptability or versatility
If screw clamping is used, then the device structure is simple, but usability and convenience are compromised
Solution Approach 1:
The seesaw mechanism and clamp beam design provide universal adaptability for different drum hoop types and thicknesses. The lever arm structure can accommodate various drum specifications through adjustable positioning, allowing one clamping mechanism to serve multiple drum types without requiring different fastening methods for each
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 rapid and convenient clamping of different drum hoops, improving usability and reducing the time required for setup and teardown.
Implementation Method 1
A compression spring is interposed between the clamp beam and the pedal beating holder and located between the clamp end and the fulcrum member to allow the leaning end to move downwards to contact the elevation difference curved surface

AI summary
A pedal beating apparatus for musical instruments comprises a pedal beating holder, an elevation adjustment tray and a clamp beam. The elevation adjustment tray is movable against the pedal beating holder and has an elevation difference curved surface. The pedal beating holder has a fulcrum member. The clamp beam hinged on the fulcrum member has a clamp end and a leaning end at two ends. A compression spring is interposed between the clamp beam and pedal beating holder and located between the clamp end and fulcrum member to allow the leaning end to move downward to contact the elevation difference curved surface. By moving the elevation adjustment tray, position of the leaning end contacting the elevation difference curved surface is adjusted to further drive the clamp end to move. Thus distance between the clamp end and clamp boss can be changed to rapidly clamp drum hoops with varying thicknesses.
