String Fine Tuner Prevents Slip-Stick via Gripping Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stringed instrument fine tuners face challenges in achieving precise and simple fine tuning, especially for strings close together, due to issues like slip-stick effects and limited space, which hinder effective adjustment and tuning.
Innovation Solution
A compact fine tuner design with a main body, gripping element, and adjustment device that allows precise deflection of strings via a spindle and displacement guide, enabling fine tuning without mounting on the instrument, and preventing slip-stick effects by lifting the string away from the instrument body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional fine tuner is mounted on the instrument body, then it provides stable tuning support, but it occupies space and causes slip-stick effects that prevent precise adjustment
Solution Approach 1:
The fine tuner is extracted from the instrument body and designed as a movable, self-supporting unit that can be positioned directly on the string. This eliminates the slip-stick effect caused by traditional mounted tuners while maintaining tuning precision through direct string contact and mechanical advantage.
Solution Approach 2:
The fine tuner acts as an intermediary between the string and the tuning mechanism, using a gripping element and adjustment device to precisely control string tension without direct mounting to the instrument body, thereby avoiding slip-stick effects.
2Adaptability or versatility
If multiple fine tuners are used on closely spaced strings, then each string can be tuned independently, but the width of the tuners prevents them from fitting in tight spaces
Solution Approach 1:
The fine tuner is segmented into compact functional components (main body, gripping element, adjustment device) arranged in a space-efficient configuration. This segmentation allows each tuner to be narrow enough for closely spaced strings while maintaining individual tuning capability for each string.
Solution Approach 2:
The design optimizes the tuner's dimensional footprint by arranging components along the string length direction rather than widening the tuner's width, enabling multiple tuners to fit on closely spaced strings without interfering with each other.
3Area of moving object
If the fine tuner is designed with a compact structure, then it fits in tight spaces, but the adjustment mechanism becomes more complex
Solution Approach 1:
The adjustment device is merged with the main body in a compact integration where the gripping element, adjustment mechanism, and support structure combine into a single space-efficient unit. This merging reduces overall width while maintaining the necessary adjustment functionality through shared components and compact geometry.
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 precise and simple fine tuning of strings in tight spaces, avoiding slip-stick effects and allowing multiple tuners to be used on closely spaced strings, particularly on instruments like the zither, with a compact and material-saving construction.
Implementation Method 1
The gripping element causes the string to be pulled away from a body of the musical instrument in order to achieve fine tuning
Implementation Method 2
an adjustment device is provided which is seated on the main body and which acts on the gripping element, the position of the gripping element relative to the adjustment device being adjusted via the adjustment device

AI summary
The invention relates to a fine tuner for a string musical instrument (10), comprising a main body (24) having an underside (44), a top side (40), a first abutment region (80) and having a second abutment region (84) for a string (22), wherein the second abutment region (84) is spaced apart from the first abutment region (80), a gripping element (86) for gripping a string portion (132) that is located between the first abutment region (80) and the second abutment region (84), and a setting device (88), which fits on the main body (24) and acts on the gripping element (86), wherein a position of the gripping element (86) relative to the main body (24) is settable in a fixable manner via the setting device (88) and the position of the gripping element (86) determines a deflected position of the string (22) at the fine tuner, wherein the gripping element (86) entrains the string portion (132) counter to a direction (48) that extends in a direction from the top side (40) to the underside (44).
