Sound Source Module Inclining Mechanism for Electronic Musical Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic musical instruments face difficulties in quickly exchanging sound source modules during performances due to cumbersome screw-based separation mechanisms and complex tilt mechanisms, which are costly and require tools, making it hard to easily attach and detach modules.
Innovation Solution
A sound source module and keyboard module design featuring engaging portions on the edge portion, where the sound source module can be easily inclined and attached/detached using a simple structure, with a spring-energized shaft portion for easy installation and removal, and a curved edge shape to reduce interference, allowing for tool-free operation and simplified handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a screw-based fixing mechanism is used to attach the sound source module to the keyboard module, then the modules can be securely fixed together, but the operation becomes troublesome and requires tools for attachment and detachment
Solution Approach 1:
The fixing mechanism is segmented into multiple engaging portions distributed around the circumference of the sound source module. These engaging portions can be independently engaged with corresponding portions on the keyboard module, allowing for tool-free attachment by simply pushing the modules together while maintaining secure fixation through distributed engagement points.
Solution Approach 2:
The screw-based mechanical fastening system is replaced with a push-to-engage mechanism featuring protruding and recessed engaging portions. This substitution eliminates the need for rotational fastening operations and tools, transforming the attachment process into a simple linear insertion motion that is both secure and easily reversible.
2Adaptability or versatility
If a tilt mechanism is used to support the rack mount member inclined relative to the keyboard module, then the sound source module can be inclined at a favored position, but the structure becomes more complicated and costly
Solution Approach 1:
The tilting function is merged with the attachment mechanism itself. The engaging portions are positioned and dimensioned such that when the sound source module is pushed onto the keyboard module, it automatically assumes an inclined position. The attachment and tilting actions are combined into a single operation, eliminating the need for separate tilt adjustment mechanisms.
Solution Approach 2:
The engaging portions serve multiple functions simultaneously: they provide mechanical fixation to prevent separation, establish the inclined angle, and guide the alignment during attachment. This multi-functionality eliminates the need for dedicated tilt mechanism components, reducing overall structural complexity while maintaining adaptability.

AI summary
Provided is a sound source module capable of inclining and capable of being easily attached and detached by a simple structure. A sound source module 10 includes engaging portions 40 and 48 provided spaced from each other on both ends of an edge portion 14 in a longitudinal direction. A keyboard module 50 is removably engaged by the engaging portions 40 and 48. Thus, the sound source module 10 can be easily attached to and detached from the keyboard module 50. The engaging portions 40 and 48 are located on the same straight line. Thus, by a front portion 11 being supported in an inclined state relative to the keyboard module 50 with the engaging portions 40 and 48 as an axis, the sound source module 10 can be inclined relative to the keyboard module 50.
