Rotating Mallet Assembly for Continuous Standing Bell Notes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior mallet assemblies for standing bells do not effectively generate a continuous note, as they lack a rotating mallet that contacts the rim of the bell to produce sustained vibrations.
Innovation Solution
A mallet assembly comprising a base with a fastener to secure a standing bell, an arm with a pivotally engaged mallet that frictionally contacts the bell's rim, and a motor to rotate the mallet, exciting continuous vibrations and producing a continuous note.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a traditional mallet assembly is used to strike a standing bell, then the bell produces a note, but the note cannot be sustained continuously
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a static mallet position to a rotating mallet mechanism. The mallet is mounted on a pivot arm that can rotate, allowing the mallet to continuously contact and rotate along the bell's rim. This dynamic motion enables sustained vibration and continuous sound production, resolving the contradiction between sound duration and device complexity.
Solution Approach 2:
The patent implements periodic action through the rotating mallet that continuously strikes and摩擦s the bell rim in a cyclical manner. The motor-driven rotation creates repeated contact points around the bell's circumference, generating sustained periodic vibrations that produce continuous sound, thereby extending the duration of sound production while maintaining manageable system complexity.
2Duration of action of moving object
If a rotating mallet is introduced to produce continuous sound, then the sound duration is extended, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the rotating mallet assembly to perform multiple functions: the motor provides rotational motion, the pivot arm enables both rotation and frictional contact, and the mallet itself serves as both a striker and a friction element. This multi-functionality reduces the need for separate components, thereby extending sound duration while controlling the increase in device complexity.
Solution Approach 2:
The patent uses the pivot arm as an intermediary component that mediates between the motor's rotational output and the mallet's contact with the bell. This intermediary mechanism allows for controlled rotation and frictional contact, enabling continuous sound production while simplifying the overall system architecture compared to direct motor-to-mallet coupling.
3Reliability
If the mallet frictionally contacts the bell rim to produce continuous vibrations, then a continuous note is generated, but the contact force must be precisely controlled
Solution Approach 1:
The patent implements feedback through the mechanical connection between the rotating mallet and the bell. The frictional contact and rotation create a self-regulating system where the contact force and vibration are continuously adjusted based on the interaction between the mallet and bell surfaces, ensuring consistent continuous note production while simplifying operation through automatic force regulation.

AI summary
A rotating mallet assembly for generating a continuous note from a standing bell includes a base, which is positionable on a substantially horizontal surface. A fastener engaged to an upper surface of the base can selectively engage a bottom of a standing bell so that the standing bell is removably engaged to the base. An arm is engaged to and extends from the base. A mallet is pivotally engaged to and extends from the arm distal from the base so that the mallet frictionally contacts a rim of the standing bell. A motor is engaged to the arm and is operationally engaged to the mallet. The motor is positioned to selectively rotate the mallet relative to the standing bell to excite continuous vibrations in the standing bell so that a continuous note is produced.
