Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting control systems for computer hosts lack compatibility due to single support interfaces, leading to incompatibility in communication interfaces between the mainboard and interface cards, restricting the selection of transmission interfaces according to different requirements.
Innovation Solution
A lighting control system comprising a light board with multiple transmission interfaces and a lighting control module, which allows the mainboard to test and select supported interfaces, enabling the emission of light beams based on operational states through various interfaces like SMBUS and USB, ensuring wide compatibility between the mainboard and light board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single support interface is used in the lighting control system, then the device complexity is reduced, but the adaptability between mainboard and light board deteriorates
Solution Approach 1:
The light board is designed with multiple transmission interfaces (first transmission interface and second transmission interface) that can support different communication protocols. The mainboard can selectively connect to either interface based on compatibility requirements, making the lighting control system universally adaptable to different interface types while maintaining relatively simple device structure.
2Adaptability or versatility
If multiple transmission interfaces are added to the light board, then the adaptability between mainboard and light board is improved, but the device complexity increases
Solution Approach 1:
The transmission interface functionality is segmented into separate first and second transmission interfaces on the light board, each capable of supporting different communication protocols. This segmentation allows the mainboard to selectively activate only the compatible interface type, achieving high adaptability while keeping the actual active interface structure relatively simple at any given time.
3Adaptability or versatility
If interface testing and selection mechanism is implemented, then the interface compatibility is improved, but the operation time increases
Solution Approach 1:
The mainboard performs interface testing by sending testing signals to both the first and second transmission interfaces before actual operation begins. The interface selection and compatibility verification are completed in advance during the initialization phase, so that once the compatible interface is identified, the system can operate without further delays. This preliminary action ensures interface compatibility is established before normal operation starts.
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 system achieves wide compatibility by allowing the mainboard to select appropriate transmission interfaces and control light emitting units based on operational states, effectively addressing the incompatibility issues and supporting multiple interface types for diverse computer host components.
Implementation Method 1
The light emitting module includes one or more light emitting units. The light emitting unit emits a light beam according to a received interface control signal or a received lighting control signal.
Data Source
AI summary
A lighting control system and a method thereof are provided. The lighting control system includes a light board and a mainboard. The light board includes a light-emitting module, transmission interfaces and a lighting control module. The mainboard outputs interface testing signals to inquire which types of the transmission interfaces are supported by the light board. The transmission interfaces output interface message signals in response to the interface testing signal. When the mainboard determines that the light board supports one or more types of the transmission interfaces indicated by the interface testing signal, the mainboard selects one of the transmission interfaces and instructs the selected transmission interface to control the light-emitting module. When the mainboard determines that the light board does not support any type of the transmission interfaces indicated by the interface testing signal, the mainboard instructs the lighting control module to control the light-emitting module.
