I2C Recognition Chips for Series-Connected LED Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Desktop computer motherboards have limited connection ports for LED strips and lighting fans, leading to insufficient recognition of individual light strips when connected in series, resulting in a uniform lighting effect rather than achieving distinct effects.
Innovation Solution
A system and method that utilize recognition chips with I2C interfaces to uniquely identify and order electronic elements like light strips and fans, allowing a control circuit board to communicate and control each element independently through a series connection, using classification codes and serial numbers to differentiate models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple light strips are connected in series to save connection ports, then the number of connection ports required is reduced, but the motherboard cannot recognize each light strip individually
Solution Approach 1:
The patent divides the identification task into segments by placing recognition chips on individual light strips. Each chip contains a unique recognition code that identifies its specific light strip. This segmentation allows the motherboard to recognize each light strip individually even when connected in series, resolving the contradiction between reducing connection ports and maintaining recognition accuracy.
Solution Approach 2:
The patent introduces recognition chips as intermediary devices between the light strips and the motherboard. These chips act as mediators that carry identification information, enabling the motherboard to distinguish between multiple light strips connected in series without requiring additional connection ports. The I2C interface serves as the communication intermediary for transmitting recognition codes.
2Measurement precision
If each electronic element is equipped with a recognition chip and I2C interface, then individual recognition and control is achieved, but the device complexity increases
Solution Approach 1:
The patent employs universal I2C communication interfaces and standardized recognition chip designs that can be applied to multiple types of electronic elements (light strips, fans, etc.). This universality allows the same recognition mechanism to serve multiple functions and different device types, reducing the overall complexity compared to implementing separate recognition systems for each device type.
3Adaptability or versatility
If recognition codes with classification codes and serial numbers are used, then different models and orders of electronic elements are distinguished, but the information processing complexity increases
Solution Approach 1:
The patent uses parameter changes in the form of classification codes and serial numbers within recognition codes to differentiate electronic elements. By varying these code parameters, the system can identify different models, types, and positions of electronic elements without requiring complex structural changes to the recognition mechanism itself.

AI summary
A system and a method for recognizing electronic elements are disclosed. The system includes at least two electronic elements and a control circuit board. The electronic elements include a fan, a light strip, or a combination of the fan and the light strip. The electronic elements are electrically connected in series. Each electronic element is provided with a recognition chip having a recognition code. The recognition chip of the next-preceding electronic element requests the recognition chip of the next-following electronic element to transmit the corresponding recognition codes back, so that the recognition chips of the electronic elements from first to last sequentially transmit the corresponding recognition codes back. The control circuit board is electrically connected with the first electronic element and sequentially receives the recognition codes according to the order of the at least two electronic elements connected in series.
