Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting effect technologies require multiple light sources and position detection systems, leading to high costs and complexity in achieving a luminance effect when an object contacts a surface.
Innovation Solution
A lighting effect device with a light-supplying unit forming a light-layer above an operation surface, using a light-uniforming unit and reflective layer to create a visible optical effect without intersecting the surface, allowing the light to be scattered and reflected for enhanced luminance at the contact point, eliminating the need for multiple light sources and position detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources are applied beneath a region to achieve luminance effect, then the illumination coverage is improved, but the device complexity and cost increase
Solution Approach 1:
The patent divides the illumination function into two parts: a single light source that generates light, and a light-guiding plate with light-emitting segments that distribute the light to multiple locations. This segmentation allows one light source to achieve the effect of multiple light sources, reducing device complexity while maintaining illumination coverage.
Solution Approach 2:
The light-guiding plate acts as an intermediary between the single light source and the operation surface. It receives light from the light source and guides it to multiple emission points, enabling the system to achieve wide illumination coverage without requiring multiple light sources directly beneath the surface.
2Measurement precision
If a position-detecting device is provided to acquire contact position, then the precision of lighting control is improved, but the device complexity and cost increase
Solution Approach 1:
The system uses the operation body itself (such as a finger or stylus) to detect its own position through the optical effect it creates. When the operation body enters the light-layer, it blocks or refracts light, creating a visible optical effect that naturally indicates its position without requiring separate detection devices.
Solution Approach 2:
The patent utilizes changes in optical properties (such as light blocking, refraction, or reflection) of the operation body to indicate its position. The operation body's interaction with the light-layer creates a visible contrast or optical effect that reveals its location, eliminating the need for electronic position-detecting devices.
3Measurement precision
If collaboration among light sources, detecting device and control system is implemented, then the lighting control precision is improved, but the implementation complexity increases
Solution Approach 1:
The system achieves lighting control through the natural optical interaction between the light-layer and the operation body. The operation body's entry into the light-layer automatically creates the desired optical effect without requiring coordination between multiple components, simplifying the implementation while maintaining control precision.
4Illumination intensity
If light sources are positioned close to the operation surface, then the luminance effect is improved, but the risk of light source damage increases
Solution Approach 1:
The light-guiding plate serves as an intermediary that allows the light source to be positioned away from the operation surface while still achieving strong luminance effects. The plate transmits and distributes light to multiple emission points close to the surface, protecting the light source from damage while maintaining illumination effectiveness.
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 reduces costs and complexity while providing a more reliable and uniform luminance effect, enhancing user experience by utilizing fewer light sources and improving the visibility of the optical effect through scattering and reflection.
Implementation Method 1
at least part of the light from the light-layer, after being reflected by an operation body which enters into the light-layer, forms a visible optical-effect around the operation body
Implementation Method 2
at least part of the light from the light-layer enters into the light-uniforming unit after being reflected by an operation body which enters into the light-layer, then the light which enters into the light-uniforming unit forms the visible optical-effect in the scattering effect of the light-uniforming unit
Implementation Method 3
a reflective layer, provided between the light-uniforming unit and the operation surface; at least part of the light from the light-layer enters into the light-uniforming unit after being reflected by an operation body which enters into the light-layer, the light which enters into the light-uniforming unit forms the visible optical-effect in the scattering effect of the light-uniforming unit and the reflection effect of the reflective layer

AI summary
A lighting effect device is provided, which is used for equipment with an operation surface that has a reflective characteristic. The lighting effect device includes at least a light supply unit for forming a light layer above the operation surface. The light layer is not crossed with the operation surface, where at least part of light of the light layer forms a visible lighting effect around an operator after reflected by the operator entering the light layer. The device requires less light sources and no position detection, so that the device is inexpensive and reliable. At the same time, a dodging layer and/or a reflective layer improve lighting effect and provide user a better experience.
