See-Through Pad Sensor Layout for Tone Surface Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic musical instruments cannot ascertain the types of tone materials allocated to individual operating surfaces during performance, requiring pre-performance testing to identify the correct surfaces.
Innovation Solution
An operation detection apparatus featuring a transparent or translucent pad with hitting portions and a sensor section that allows users to see through a see-through portion, displaying icons indicative of tone materials allocated to each hitting portion, enabling intuitive performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a transparent or translucent pad with see-through portions is provided, then users can identify tone materials during performance, but the device structure becomes more complex
Solution Approach 1:
The pad utilizes transparency and translucency properties to allow visual information transmission. The see-through portions enable users to see display content through the pad material, providing tone material identification during performance without adding complex electronic components to the pad structure itself.
Solution Approach 2:
The transparent pad acts as an intermediary element between the display and the user. It allows visual information to pass through while maintaining the functional hitting surface, mediating between the need for visual feedback and the need for a responsive performance surface.
2Device complexity
If users must test-hitting operating surfaces to identify tone materials, then the instrument structure remains simple, but time is lost during pre-performance setup
Solution Approach 1:
The display shows tone material information in advance through the see-through portions of the pad, allowing users to identify which surfaces correspond to which tone materials before performance begins. This preliminary visual identification eliminates the need for time-consuming test-hitting during setup.
Solution Approach 2:
The system provides visual feedback through the transparent pad, showing users which tone materials are allocated to which operating surfaces. This immediate visual feedback replaces the trial-and-error test-hitting process, reducing setup time while maintaining simple instrument structure.
3Ease of operation
If the pad is made transparent or translucent to show display content, then usability during performance improves, but manufacturing precision requirements increase
Solution Approach 1:
The pad is designed with different optical properties in different regions. The see-through portions have specific transparency characteristics that allow display visibility, while other portions may have different properties. This local differentiation optimizes both usability and manufacturing considerations by applying precision requirements only where necessary.

AI summary
Operation detection apparatus includes a sensor section, and a pad formed of a transparent or translucent material and including at least one hitting portion provided on its surface. The hitting portion is suitable for being hit by a user. The sensor section is provided in a region positionally corresponding to the hitting portion under the pad, to detect hitting of the hitting portion. The sensor section includes a see-through portion provided in association with the hitting portion for allowing a region below the sensor section to be partly seen therethrough. The sensor section is sheet-shaped as a whole, and the see-through portion is an opening provided in a predetermined position of the sheet-shaped sensor section. Display area is located under the sensor section and exposed through the opening.
