Bass Drum Pedal Pivotable Post Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bass-drum pedal assemblies are bulky, difficult to transport, and require complex attachment and detachment processes, which complicate setup, teardown, and transportation of drum kits.
Innovation Solution
A pedal assembly with a pivotable post that can be easily retracted from a vertical operating position to a horizontal transport position, featuring a locking mechanism with detent notches and a spring-loaded coupling, and a clamping system with an adjustment screw for secure attachment to the drum hoop, allowing for compact storage and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the post is fixed in an erect position to ensure stable operation, then the operational stability is improved, but the transportability and storage efficiency deteriorate due to large overall height
Solution Approach 1:
The post is designed to be movable between an erect operating position and a recumbent transport position through a pivot connection. This dynamic configuration allows the post to adapt its orientation based on operational or transport requirements, resolving the contradiction between stability during use and compactness during storage.
Solution Approach 2:
The post is divided into segments that can be relative movable with respect to each other, allowing the upper portion to be positioned vertically for operation and the lower portion to be folded horizontally for transport. This segmentation enables the structure to achieve both stability and compactness at different times.
2Reliability
If the pedal assembly uses a clamp or clamp system to secure to the drum hoop, then the attachment security is improved, but the device complexity and number of parts increase
Solution Approach 1:
The clamp is integrated as part of the pedal assembly itself rather than being a separate component. The floor plate of the pedal assembly incorporates the clamping function, merging the attachment mechanism with the main structure and reducing the total number of parts while maintaining secure attachment.
Solution Approach 2:
The floor plate serves multiple functions: it provides the base for the pedal mechanism and simultaneously functions as the clamping element that secures the entire assembly to the drum hoop. This multi-functionality reduces the need for separate dedicated clamping components.
3Ease of operation
If the post is detachably mounted to allow disassembly, then the ease of assembly and disassembly is improved, but the operational reliability and structural integrity deteriorate
Solution Approach 1:
The post uses a pivot connection that allows for easy attachment and detachment while maintaining structural integrity when in the erect position. The dynamic nature of the pivot enables simple assembly/disassembly operations without compromising the rigidity and stability of the post during drumming operations.

AI summary
A pedal assembly for a drum has a floor plate, a clamp for securing the floor plate to a hoop of a drum, a pivot on the floor plate, a post pivotal on the pivot of the floor plate between an erect operating position extending upward from the floor plate and a transport position recumbent on the floor plate. An upper end of the post is adapted to hold a beater shaft. A pedal pivotal on the plate is couplable to the beater shaft. A latch releasably locks the post in at least the operating position.
