Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If all LEDs are illuminated simultaneously to meet luminous lens area requirements, then light coverage is sufficient, but motion simulation capability is lost
Solution Approach 1:
The LED array is divided into multiple independently controllable groups or segments along the base plate. The control board can selectively illuminate different segments in sequence or combination, enabling both sufficient light coverage when all segments are activated and motion simulation when segments are activated in predetermined sequences.
2Adaptability or versatility
If LEDs are illuminated in sequence to simulate motion, then adaptability and visual effect are improved, but luminous lens area coverage may be insufficient at any given moment
Solution Approach 1:
The lighting system transitions from static simultaneous illumination to dynamic sequential illumination. The control board implements predetermined sequences that activate different LED groups at different times, creating motion simulation effects while maintaining the ability to provide sufficient coverage when needed.
Solution Approach 2:
The system uses periodic activation patterns where LED groups are illuminated in repeating sequences. This creates the visual effect of motion while ensuring that over time, all areas receive adequate illumination to meet luminous lens area requirements.
3Device complexity
If a simple illumination system is used, then device complexity is low, but ability to simulate motion and customize lighting sequences is limited
Solution Approach 1:
A control board serves as an intermediary between the power source and the LED array. This intermediary component enables complex functions including predetermined sequences, motion simulation, and customization without requiring complex circuitry in the LED elements themselves, thus maintaining relative system simplicity while achieving high versatility.

AI summary
A tail light assembly includes a lighting assembly and a control board. The lighting assembly includes a base plate and a plurality of light-emitting diodes (LEDs). The control board is electrically connected to each of the LEDs. The control board receives an activation signal from a device. In response, the control board sequentially sends an illumination signal to LEDs of each of a plurality of groups of LEDs to thereby sequentially illuminate the groups of LEDs. The control board also selectively and sequentially sends a termination signal to LEDs of the various groups of LED, in alternating relationship to sending the illumination signal. The sequential illumination and turning off of the plurality of LEDs simulates motion of waves propagating across the base plate.
