Motor-Driven Wobble Arm Wind Chime
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind chimes require wind to produce sound, limiting their functionality in calm conditions.
Innovation Solution
An automated wind chime system featuring a motor-driven wobble arm within a novelty-shaped housing that rotates to create an erratic movement, causing a clapper to strike percussion targets and produce music, even in the absence of wind, with a power control for motor operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor-driven wobble arm is added to enable music production without wind, then the functionality in calm conditions is improved, but the device complexity increases
Solution Approach 1:
The patent combines the motor-driven wobble mechanism with the traditional wind chime structure, integrating both wind-powered and motor-powered sound production capabilities into a single device. This allows the chime to function in both windy and calm conditions without requiring separate systems.
Solution Approach 2:
The wind chime is designed to perform multiple functions: it can produce music through wind action on traditional elements, and alternatively produce music through the motor-driven wobble arm when wind is absent. This multi-functionality resolves the contradiction by making the device adaptable to different environmental conditions.
2Productivity
If an unbalanced wobble arm is used to create erratic movement patterns, then the sound variety is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The wobble arm is deliberately designed with an unbalanced, asymmetric configuration to create erratic and varied movement patterns. This asymmetry is intentional and requires precise manufacturing to ensure the desired chaotic motion, directly addressing the contradiction between sound variety and manufacturing precision.
3Adaptability or versatility
If multiple control settings are added for rotational speed and timing, then the user customization is improved, but the ease of operation decreases
Solution Approach 1:
The control system allows dynamic adjustment of rotational speed and timing parameters, enabling users to customize the motor's operation. While this increases adaptability, it also complicates the ease of operation by introducing multiple controls that require user interaction and adjustment.
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 continuous music production without wind, offering customizable sound patterns through adjustable rotational speed and imbalance settings, enhancing aesthetic appeal with various housing designs.
Implementation Method 1
A motor within the housing may rotate the wobble arm when energized
Implementation Method 2
The wobble arm may be unbalanced such that rotation of the wobble arm causes the housing to sway in an erratic pattern
Implementation Method 3
Moving the housing in the erratic pattern may cause the clapper to strike a plurality of percussion targets within the wind chime thus producing chime music

AI summary
The automated wind chime comprises a housing and a wobble arm. The housing may be suspended from a clapper of a wind chime. A motor within the housing may rotate the wobble arm when energized. The wobble arm may be unbalanced such that rotation of the wobble arm causes the housing to sway in an erratic pattern. Moving the housing in the erratic pattern may cause the clapper to strike a plurality of percussion targets within the wind chime thus producing chime music even in the absence of wind. The housing may have a novelty appearance. As non-limiting examples, the housing may be shaped like a duck, turkey, Easter bunny, Santa Claus, musical note, or flower.
