Grand Piano Topboard Reflection Preventer for Concert Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grand pianos experience lighting reflection issues when used in concerts with orchestras, causing discomfort for orchestra players due to the glossy topboard surfaces, and existing solutions either degrade the piano's appearance or require labor-intensive matte coating applications.
Innovation Solution
A topboard reflection preventer system that attaches to the grand piano's openable topboard, covering its upper surfaces and held in place by minimal holding means to prevent reflection, allowing for easy attachment and removal, maintaining the piano's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If matte processing is applied to the upper surface of the topboard, then lighting reflection is prevented, but the appearance of the piano is degraded due to mixed gloss and matte surfaces
Solution Approach 1:
The topboard is divided into two functional zones: the upper surface maintains gloss coating for aesthetic purposes, while the lower surface receives matte processing to prevent lighting reflection. This segmentation allows each surface to serve its specific function without compromising the other.
Solution Approach 2:
Matte processing is applied locally only to the lower surface of the topboard where lighting reflection occurs, while the upper surface retains its gloss coating. This localized treatment prevents reflection without degrading the overall appearance of the piano.
2Object-affected harmful factors
If matte coating is sprayed on the upper surface of the topboard, then lighting reflection is prevented, but the work requires much time and labor
Solution Approach 1:
Instead of applying matte coating to the upper surface of the topboard as conventionally done, the invention inverts the approach by applying matte processing to the lower surface. This reversal eliminates the need for time-consuming spray application while still achieving the reflection prevention goal.
3Ease of operation
If the topboard front is folded back onto the topboard rear, then the topboard can be held open, but the topboard front exposes the lower surface which causes lighting reflection
Solution Approach 1:
The lower surface of the topboard front is pre-treated with matte processing before the topboard is opened. This preliminary action ensures that when the topboard front is folded back onto the topboard rear, the exposed lower surface will not cause lighting reflection, thus resolving the contradiction between ease of operation and prevention of harmful factors.

AI summary
A topboard reflection preventer for a grand piano, which is capable of positively preventing lighting from being reflected by an open topboard, while maintaining excellent appearance of a piano body. The topboard reflection preventer for a grand piano is attached to an openable and closable topboard formed by a topboard rear and a topboard front, and prevents lighting from above from being reflected by the topboard in a state of the topboard held open in an inclined position. The topboard reflection preventer includes a reflection preventer body attached to the topboard rear and the topboard front folded onto the topboard rear, in a state covering whole upper surfaces of the topboard rear and the topboard front, and a holding member for holding the reflection preventer body so as to prevent the reflection preventer body from falling off the topboard held open in the inclined position.
