Removable Piano Pedal Sensor Mount for Versatile Angle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The configuration of existing piano pedal detection systems lacks versatility due to variations in lyre shape and relative pedal rod positions across different piano models, making it difficult to mount displacement sensors effectively.
Innovation Solution
A detection device with a removable casing featuring a fastener and sensor that can be fixed to a piano pedal using a clamp mechanism, allowing for the calculation of pedaling angles based on sensor output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a displacement sensor is mounted to detect pedal amount, then the pedaling amount can be detected, but the mounting configuration has poor versatility due to variations in lyre shape and pedal rod position across different piano models
Solution Approach 1:
The detection device is designed with a universal mounting structure that can be attached to various piano pedal types (soft pedal, loud pedal, sostenuto pedal) across different piano models. The casing includes a mounting portion that adapts to different pedal shapes and positions, allowing the same sensor unit to detect pedaling amount on multiple pedal types without requiring model-specific customization.
Solution Approach 2:
The detection device is divided into separate functional modules: a casing with mounting portion for attachment, a sensor unit for detection, and a processor for calculation. This segmentation allows each component to be independently optimized and easily reconfigured for different pedal types and piano models, enhancing overall versatility while maintaining detection precision.
2Reliability
If the detection device is designed with a fixed mounting structure, then the sensor can be securely attached, but the device cannot adapt to different pedal shapes and positions across various piano models
Solution Approach 1:
The mounting portion of the casing is designed with adjustable and reconfigurable features that allow it to adapt dynamically to different pedal shapes, sizes, and positions. The mounting structure can be adjusted to accommodate various pedal configurations while maintaining secure attachment, enabling the same detection device to reliably operate on different pedal types across various piano models.
