Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-burning address sequence data is performed on each LED before assembly, then the LEDs can be controlled to light in diverse patterns, but the process becomes complicated and difficult, and correct illumination cannot be achieved if LEDs are not assembled in strict sequence
Solution Approach 1:
The patent applies preliminary action by burning the counting ordinal number into each LED module during the manufacturing process before assembly. This pre-stored identification data enables the LEDs to be automatically sequenced during operation without requiring complex pre-assembly procedures or strict assembly sequencing, thus resolving the contradiction between achieving diverse illumination and simplifying the sequencing process
Solution Approach 2:
The patent implements self-service by enabling each LED module to automatically identify its own position in the sequence through the burned-in counting ordinal number. When control signals are sent, each module uses its stored number to determine when to activate, eliminating the need for external sequencing control or complex assembly procedures, thereby reducing process complexity while maintaining diverse illumination capabilities
2Adaptability or versatility
If different address sequence data is assigned to each LED for diverse lighting control, then various lighting output effects can be achieved, but the method of sequencing becomes complicated and difficult
Solution Approach 1:
The patent applies preliminary action by pre-burning the counting ordinal number into each LED module during manufacturing. This advance preparation eliminates the need for complex operational sequencing procedures, as the modules automatically use their stored numbers to determine their activation order, making the system easy to operate while maintaining diverse lighting effects
Solution Approach 2:
The patent changes the parameter used for sequencing from complex address sequence data to a simple counting ordinal number. Each LED module stores only its position number in the sequence, and the controller sends signals based on these numbers, simplifying the operation while still enabling diverse lighting patterns through different control strategies
3Productivity
If LEDs are assembled without sequential ordering, then assembly becomes simpler and faster, but the diverse illumination effects cannot be correctly achieved
Solution Approach 1:
The patent applies preliminary action by embedding the counting ordinal number into each LED module during manufacturing, before assembly. This allows modules to be assembled in any order without affecting the final sequencing, as each module uses its pre-stored number to determine its position in the light sequence, thereby maintaining both high assembly productivity and reliable illumination effects
Solution Approach 2:
The patent implements self-service by enabling each LED module to automatically determine its own sequence position using the burned-in counting ordinal number. During operation, modules self-identify and activate in the correct order based on their stored numbers, eliminating the need for strict assembly sequencing while ensuring accurate illumination effects, thus resolving the contradiction between assembly speed and reliability

AI summary
A pixel-controlled LED light includes a plurality of LED modules and a controller. Each LED module includes at least one LED and a LED drive apparatus. The LED drive apparatus burns a counting ordinal number according to connection sequence thereof. The controller defines the counting ordinal number of the LED modules which need to be changed their light modes as a target value, and sequentially transmits light mode data whose number is greater than or equal to the target value to each of the LED modules. The LED drive apparatuses sequentially receive the light mode data for counting. If the sequence of the light mode data meets to the counting ordinal number of the LED drive apparatus, the LED drive apparatuses identify the light mode data that are met, and after identifying the light mode data, the LED drive apparatuses control the corresponding at least one LED.
