Solution Overview
Problem
Current luminous surfaces lack the ability to be easily customized in shape and layout to meet the specific design or architectural requirements, limiting their versatility and adaptability.
Innovation Solution
A light-emitting assembly comprising a cuttable substrate with arranged light strips and a power connection member, along with a control system that allows for independent power and data control of the light strips, enabling customizable layouts by cutting portions while maintaining functionality through multiple connection points and controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If luminous surfaces are made customizable in shape and layout, then adaptability and versatility are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The light-emitting assembly is divided into multiple independent light strips that can be individually controlled and powered. Each light strip contains its own light nodes and can be independently cut or removed, allowing flexible customization of the overall assembly layout while maintaining simple power distribution through the connection member
Solution Approach 2:
The connection member serves multiple functions: it provides mechanical support for mounting light strips, establishes electrical power connections to all light strips, and enables customizable layout configurations. This multi-functionality reduces the need for separate components and simplifies the overall device structure
2Adaptability or versatility
If portions of the light-emitting assembly are cut away for customization, then layout flexibility is improved, but reliability of power supply may deteriorate
Solution Approach 1:
The connection member is designed in advance with extended leads that protrude beyond the main body of the assembly. These pre-positioned leads ensure that even when portions of the assembly are cut away for customization, the power supply connections remain intact and functional, maintaining reliability while enabling layout flexibility
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
Enables the creation of customizable light-emitting surfaces that can fit various shapes and functions, providing flexible and adaptive lighting solutions for complex surfaces, including curved or angular designs, while ensuring continuous power supply and control to the light strips.
Implementation Method 1
Each light node may comprise a light source such as, for example, light-emitting diodes (LEDs)
Implementation Method 2
a light node may comprise a combination of red, green and blue LEDs enabling the light node to emit light with a wide range of possible colors

AI summary
A light-emitting assembly comprising a substrate adapted to be cut, a plurality of light strips and a first connection member extending longitudinally over at least part of the substrate for supplying power to the plurality of light strips is provided. A first group of linear light strips extend over the substrate from a first side of the first connection member, and a second group of linear light strips extend over the substrate from a second side, opposite to the first side, of the first connection member. The assembly further comprises a controller system configured to control a power supply to a light strip of the plurality of light strips via the first connection member. The plurality of light strips and/or the first connection member are adapted to be cut to customize a layout of the light-emitting assembly.
