Grand Piano Rim Light Patterns via Semi-Transmitting Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grand pianos with transparent visible members lack enhanced visual appeal due to visible fixtures and lack of light manipulation, limiting their aesthetic beauty.
Innovation Solution
Incorporating a semi-light transmitting outer layer, a reflective inner layer, and a bottom layer with strategically placed point light sources, such as LEDs, to create patterns on the rim and lid, enhancing visual appearance by reflecting and passing light in a controlled manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a transparent rim is used, then the visual structure is simplified and modern aesthetic is achieved, but the frame fixtures become visible and aesthetic beauty deteriorates
Solution Approach 1:
An outer layer is introduced as an intermediary component between the transparent rim and the viewer. This outer layer selectively transmits and reflects light to create visual patterns that obscure the frame fixtures while preserving the overall transparent aesthetic of the rim structure.
Solution Approach 2:
The outer layer utilizes optical properties to create dynamic visual effects through light interaction. By controlling light transmission and reflection, the outer layer creates patterns that change appearance based on lighting conditions, effectively hiding frame fixtures while maintaining aesthetic appeal.
2Ease of manufacture
If multiple layers and light sources are added, then visual appearance and aesthetic beauty are enhanced, but device complexity increases
Solution Approach 1:
The rim structure is segmented into multiple functional layers (outer layer, inner layer, bottom layer) with distinct optical properties. This segmentation allows each layer to perform a specific function in light manipulation, creating complex visual effects while maintaining modular simplicity in the overall design.
Solution Approach 2:
The visual appearance of the rim is made dynamic through the integration of light sources that can be controlled to create different patterns and effects. The outer layer's selective light transmission and reflection properties create dynamic visual changes based on lighting conditions, enhancing aesthetic beauty without requiring complex mechanical adjustments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly enhances the visual beauty of the grand piano by creating patterns on the rim and lid, hiding frame fixtures and improving aesthetic appeal compared to standard transparent material designs.
Implementation Method 1
the outer layer being formed of a semi-light transmitting material, which reflects part of light received through the rim and allows a rest of the light received through the rim, other than the part reflected, to pass through
Implementation Method 2
the inner layer being formed of a material reflecting light received through the rim
Implementation Method 3
the bottom layer being formed of a material reflecting light received through the rim
Implementation Method 4
the light source comprising a plurality of point light sources arranged in series in a longitudinal direction of the outer layer at a position facing a lowest section of the outer layer across the rim on an area facing the inner surface of the rim, the plurality of point light sources emitting light toward the rim
