Adjustable Pedal Unit for Electronic Keyboard Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic keyboard instruments do not allow users to freely adjust the position of the keyboard and pedal portions in the front-back direction, leading to uncomfortable playing postures due to fixed height settings that determine the positional relationship between hands and feet.
Innovation Solution
An electronic musical instrument with a stand portion supporting the main body, a fixed unit for the keyboard, and a moving pedal unit that can be adjusted frontward and backward, equipped with a restricting mechanism to allow flexible positioning based on user operation, enabling separate adjustment of the keyboard and pedal positions to suit individual physiques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the height of the keyboard portion is fixed to determine its front-back directional position, then the structural stability is improved, but the adaptability for users of various physiques deteriorates
Solution Approach 1:
The pedal unit is designed to be movable in the front-back direction relative to the keyboard portion, allowing users to adjust the distance between their feet and hands according to their physique. The unit can be fixed at desired positions using a fixing mechanism, thus providing both mobility for adaptation and stability when fixed.
2Device complexity
If the pedal unit position is fixed relative to the keyboard, then the device complexity is reduced, but the ease of operation for users of various physiques deteriorates
Solution Approach 1:
The pedal unit is separated from the keyboard portion and mounted on the stand portion independently. This segmentation allows the pedal unit to be adjusted and fixed at different front-back positions, enabling users of various physiques to operate the instrument comfortably without increasing overall device complexity.
3Manufacturing precision
If the keyboard and pedal portions are positioned according to fixed height settings, then the manufacturing precision is improved, but the adaptability for different user postures deteriorates
Solution Approach 1:
The pedal unit is designed with movable and fixed capabilities in the front-back direction. Users can adjust the position according to their posture requirements and fix it at the desired location, maintaining manufacturing precision while achieving adaptability for different user physiques and postures.

AI summary
A main body 10 having a keyboard operated with player's hands is supported on both sides thereof by stand portions 22, 24. To the lower end of the stand portions 22, 24, a fixed unit 52 is fixed. On the fixed unit 52, a moving unit 60 is mounted so that the moving unit 60 can move frontward and backward. On the moving unit 60, a pedal 62 operated with a player's foot is mounted. Separately from the keyboard operated with the hands, as a result, the player is allowed to adjust his desired front-back directional position of the pedal 62.
