Solution Overview

Problem

Traditional tremolo systems for stringed instruments require frequent re-balancing due to changes in tuning, string gauge, or string breakage, and lack versatility and tuning stability, especially when altering the pitch of individual strings.

Innovation Solution

A tremolo device with a stationary frame, moving frame, linear guideway, and spring system that alters string tension through translational motion on a ramp, isolating spring tension effects and maintaining consistent string tuning by transferring force through the instrument body, reducing friction and maintaining original tension and position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional floating tremolo units use springs to counteract string tension, then pitch shifting capability is achieved, but re-balancing is required whenever tuning, string gauge, or string configuration changes

Engineering Contradiction:
Improvepitch shifting capabilityVSAvoidsetup and maintenance
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bridge assembly is segmented into a stationary bridge portion and a movable tremolo portion, allowing independent adjustment of each component. This segmentation enables the tremolo mechanism to be adjusted without affecting the overall bridge setup, eliminating the need for complete re-balancing when changing strings or tunings.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tremolo mechanism is pre-adjusted during initial setup to establish a neutral position that accounts for the specific string configuration. This preliminary adjustment creates a reference point that remains valid across tuning and string gauge changes, preventing the need for frequent re-balancing.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional floating tremolo units use springs to counteract string tension, then pitch shifting up and down is enabled, but tuning stability is compromised across tuning changes

Engineering Contradiction:
Improvepitch shifting rangeVSAvoidtuning stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The spring tension system is extracted from the traditional floating tremolo configuration and repositioned to act independently on the movable bridge portion. This extraction allows the spring force to be decoupled from the overall bridge stability, enabling wide pitch shifting range while maintaining tuning stability through separate adjustment mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The bridge assembly incorporates dynamic adjustment capabilities that allow the tremolo mechanism to adapt its neutral position based on the current string configuration. This dynamic adaptation maintains tuning stability across different tunings and string gauges while preserving the full pitch shifting range.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If Bigsby tremolo system uses a stationary bridge with rotating cylinder, then ease of setup is improved, but versatility and scope of pitch shift are limited

Engineering Contradiction:
Improvesetup simplicityVSAvoidpitch shifting capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The stationary bridge is enhanced with a movable tremolo portion that can be dynamically adjusted to achieve various pitch shifts. This dynamic component adds versatility and pitch shifting range while maintaining the simplicity of the stationary bridge setup through independent adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bridge assembly combines the simplicity of a stationary bridge with the functionality of a tremolo mechanism, creating a multi-functional system. The movable portion can be adjusted to provide different pitch shifting ranges and configurations, making the system universally applicable to various playing styles and string configurations while retaining ease of setup.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A tremolo apparatus is provided having a stationary frame, a moving frame, at least one linear guideway, a string retainer, and at least one spring. The stationary frame is configured to be affixed to a planar surface of a stringed instrument. The moving frame has at least one ramp with a flat segment and is guided for oscillation relative to the stationary frame. The at least one linear guideway is provided by the stationary frame or the moving frame and supports the moving frame for oscillation. The string retainer has a plurality of string capture bores and engages with the ramp surface to carry a plurality of strings reciprocally as the string bar rides the ramp surface and reciprocates to alter tension of the strings carried terminally of the string retainer. The at least one spring is interposed between the frames to position the string retainer within the flat segment.
