Dismountable Double Bass With Split Fingerboard And Segmented Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stringed musical instruments, particularly double basses, face challenges in transportation due to their size and fragility, with existing solutions either compromising sound quality or being impractical and expensive, and there is a need for a disassembleable instrument that maintains sound quality and playability.
Innovation Solution
The instrument is designed to be disassembled into four main parts: the fingerboard, neck, body, and shoulders, with a pin-through-slotted-hole joint system and a T hammer bolt for neck attachment, a latch toggle clamp for fingerboard assembly, and collapsible shoulders, allowing for easy reassembly and maintaining acoustic sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the double bass is transported in a hard shell case, then the instrument is protected from damage, but the case is very bulky and expensive
Solution Approach 1:
The double bass is divided into multiple separable components: the body, neck, and fingerboard can be detached from each other. This segmentation allows the instrument to be packed in smaller, more manageable sections rather than requiring a single large hard case, reducing overall bulkiness while maintaining protection during transport.
2Volume of moving object
If the double bass is transported in a soft bodied case, then the case is less bulky, but the instrument receives inadequate protection
Solution Approach 1:
By segmenting the instrument into separate parts, each component can be individually protected in smaller cases. The detachment mechanisms are designed to protect vulnerable areas like the neck joint, providing adequate protection without requiring a bulky soft case that encompasses the entire assembled instrument.
3Ease of operation
If the fingerboard is solidly attached to the neck, then the instrument maintains perfect intonation and playability, but the instrument cannot be disassembled for easy transportation
Solution Approach 1:
The fingerboard attachment transitions from a static permanent bond to a dynamic reversible connection. The neck features a receptacle that receives the fingerboard with a detent mechanism, allowing the fingerboard to be securely held during play for perfect intonation while enabling easy detachment for transportation. This dynamic connection adapts between the playing state (secured) and transport state (detached).

AI summary
A dismountable stringed musical instrument with a splittable fingerboard and an acoustic sound is disclosed having a hollow body composed by two parts shaped as half empty shell that meets each other on their outer perimeter, defining a sound chamber. The fingerboard is splitted in two parts that can be re-assembled by a rigid inner core which works as a reinforcement and as a trail to allows the fingerboard cutted portions to slide on it meeting each other perfectly and by a latch toggle clamp which hold the two parts strictly merged together, taking back the fingerboard to its original playable smoothness. The neck can be dismounted to from the body and then re-assembled in the playing position also adjusting its inclination at will by movable elements placed on the neck extremity which faces the top portion of the body support area.
