Clockwork Striking Mechanism Double Percussion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clockwork striking mechanisms produce extraneous noises due to hammer rebound on fixed elements during return strokes, resulting in uncontrolled and unpleasant sound emissions.
Innovation Solution
Implementing a double percussion mechanism where the hammer strikes in both directions, using either a single or two stamps, with the option of the same or different frequencies, to minimize rebound noise and enhance sound control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple percussion mechanism is used, then the device complexity is low, but parasitic noises are generated due to hammer rebound on fixed elements
Solution Approach 1:
The striking mechanism is segmented into two distinct striking zones: a first striking zone that strikes a first resonant component in a first direction, and a second striking zone that strikes a second resonant component in a second direction opposite to the first direction. This segmentation allows the hammer to be utilized in both directions of travel, converting the previously harmful rebound into a useful second strike that produces controlled sound rather than parasitic noise.
Solution Approach 2:
The rebound of the hammer, which previously caused harmful parasitic noises when striking fixed elements, is converted into a beneficial second strike. The second striking zone is specifically designed to strike a second resonant component during the return stroke, transforming the unwanted rebound energy into a controlled acoustic output that enhances the overall sound emission.
2Object-generated harmful factors
If a double percussion mechanism is implemented, then sound control and elegance are improved, but the device complexity increases
Solution Approach 1:
The hammer is designed with multi-functionality, serving both as a primary striker in the first direction and as a secondary striker in the opposite direction. By incorporating both a first striking zone and a second striking zone on the same hammer, the mechanism achieves double percussion without requiring separate hammer assemblies, thereby controlling sound emission while limiting the increase in device complexity.
Solution Approach 2:
The striking mechanism utilizes the dynamic motion of the hammer in both directions of travel. The control mechanism is designed to allow the hammer to freely oscillate between the first and second striking zones, with each direction of travel contributing to the sound emission. This dynamic utilization of hammer motion enables sophisticated sound control through the interaction of two striking zones with resonant components.
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 solution eliminates parasitic noises, restores energy during hammer rotation change, increases sound level, and protects the hammer and sinker from impact, resulting in a more controlled and elegant sound emission.
Implementation Method 1
a first striking zone, which is arranged to strike in a first direction of travel a first resonant component at the level of a first striking surface
Implementation Method 2
a second striking zone, which is arranged to strike in a second direction of travel opposite to the first direction of travel, during a recoil of the at least one hammer from a position of first percussion towards the recoil position, a second striking surface which comprises either the first resonant component or a second resonant component distinct from the first resonant component
