Keyboard Panel Support via Inter-Key Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic keyboard instruments require space for panel supporting members behind the chassis, leading to increased depth size, which restricts design flexibility and compactness.
Innovation Solution
The electronic keyboard instrument features panel supporting members mounted on the upper surface of the chassis within spaces formed between the rear ends of white and black keys, eliminating the need for rear mounting spaces and allowing for a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If panel supporting members are arranged behind the chassis, then the panel can be supported, but the depth size of the electronic keyboard instrument increases
Solution Approach 1:
The panel supporting members are relocated from the depth direction (behind the chassis) to the width direction (between adjacent black keys on the upper surface of the chassis). This dimensional transition allows the panel to be supported without increasing the depth size of the instrument, as the supporting function is achieved through a different spatial dimension.
Solution Approach 2:
The panel supporting members are positioned within the spaces between adjacent black keys, effectively utilizing the existing gaps in the key arrangement. This nesting approach allows the supporting members to be integrated into the keyboard structure without requiring additional external space, thereby maintaining a compact depth size while providing necessary panel support.
2Strength
If spaces are allocated behind the chassis for panel supporting members, then panel support is achieved, but the overall volume of the instrument increases
Solution Approach 1:
The panel supporting members are nested within the spaces between adjacent black keys on the chassis upper surface. By utilizing these existing inter-key spaces, the supporting members are accommodated within the instrument's existing volume rather than requiring additional space behind the chassis, thus avoiding an increase in overall instrument volume while still providing effective panel support.
Solution Approach 2:
The supporting structure transitions from a depth-oriented arrangement (behind the chassis) to a width-oriented arrangement (between keys on the upper surface). This dimensional shift allows the panel to be supported using the lateral spaces between keys, thereby maintaining the instrument's compact volume without compromising structural support.

AI summary
An electronic keyboard instrument includes at least one panel supporting member which supports a panel, the at least one panel supporting member is disposed in spaces formed on an upper surface of a chassis, and the spaces are spaces generated behind rear ends of white keys between two adjacent black keys by arranging a plurality of keys in a manner that rear ends of a plurality of black keys are positioned behind rear ends of a plurality of white keys.
