Interchangeable Pickup Support for String Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pickup supports for electric stringed musical instruments face challenges in efficient and stable attachment, with threaded elements being time-consuming and ball positioners being unstable, especially under string vibrations, making quick changes during performances difficult.
Innovation Solution
A pickup support with a fastener element that can be moved radially through actuation means, featuring symmetrical ends projecting through holes on the base body, and retained by helical springs for secure attachment, allowing faster and more efficient positioning and removal while maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded elements are used for attachment, then mechanical attachment reliability is improved, but the time required for exchanging pickup supports increases
Solution Approach 1:
The attachment system is divided into separate components: a fastener element with projection means that can be independently inserted into receiving grooves, and a retaining element that separately secures the fastener. This segmentation allows the pickup support to be quickly attached by simply inserting the fastener element, eliminating the time-consuming threading process while maintaining reliable mechanical attachment through the projection-receiving groove interface.
2Productivity
If ball positioners are used for attachment, then the speed of positioning and removal is improved, but attachment stability against vibrations deteriorates
Solution Approach 1:
The invention extracts the problematic ball positioner mechanism and replaces it with a fastener element that has projection means designed to fit into receiving grooves. This extraction eliminates the vibration instability issue inherent in ball positioners while preserving the quick attachment capability, as the projection means can be rapidly inserted into and secured within the receiving grooves without requiring complex positioning mechanisms.
3Productivity
If pressure is applied for positioning and removal, then attachment speed is improved, but the strength required for operation increases making it difficult during performance
Solution Approach 1:
The retaining element is designed to dynamically adjust its retention force. During normal operation, it provides sufficient holding force to maintain stable attachment against string vibrations. However, when activation means are engaged, the retaining element releases the fastener element, allowing easy removal without requiring excessive manual strength. This dynamic behavior enables quick changes during performance while maintaining operational ease.
