Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a timed signaling system with simultaneous lighting of four direction change indicator lights is used, then the signaling function is simple and reliable, but the orientation and power of illumination cannot be modified and the system lacks adaptability
Solution Approach 1:
The patent applies the dynamics principle by making the lighting modules rotatable around vertical axes, allowing them to change orientation dynamically. Each module can rotate to different positions (e.g., 0°, 45°, 90°, 135°) to direct light beams in different directions, enabling the system to adapt lighting orientation and intensity to various driving conditions and preferences.
Solution Approach 2:
The patent divides the headlight into multiple independent rotating modules, each capable of individual rotation and control. This segmentation allows each module to be independently adjusted in orientation and intensity, providing granular control over the lighting pattern and enabling versatile lighting configurations without requiring complete system redesign.
2Adaptability or versatility
If rotating modules with 180° rotation range are used to provide diverse lighting configurations, then the adaptability and visual attractiveness are improved, but the device complexity and control requirements increase
Solution Approach 1:
The patent implements periodic action through predefined animation sequences that cycle through various lighting configurations. The control unit executes programmed patterns of module rotations and intensity variations, creating attractive visual effects for vehicle identification and brand recognition without requiring complex real-time control algorithms.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit monitors the position and state of rotating modules, adjusting control signals to maintain desired lighting configurations. This feedback ensures reliable operation of the enhanced lighting system despite the increased mechanical complexity of multiple rotating components.

AI summary
The invention relates to a lighting and/or indicating device for a motor vehicle (1) comprising a control unit connected to a vehicle access control device characterized in that each of the first (51) and second (52) rotating modules has a first surface (MIR) and a second surface (MOT) opposite the first: wherein the first surface (MIR) has a reflective surface (37) capable of directing the light beam (40) emitted by the first source of white light (33) toward said area and the second surface (MOT) bears a pattern; wherein said control unit asynchronously controls the rotation of the first and second rotating modules (51, 52) following detection of a control signal received by the vehicle access control device to direct the first surfaces (MIR) thereof toward said area via a series of at least two rotations of at least 180°, first in one direction then in the other, of each rotating module (51, 52) with a brightness determined according to the rotation of each module (51, 52). Said control unit asynchronously directs the modules (51, 52) before the end of a cycle having a predetermined duration such that the second surfaces thereof (MOT) are visible from outside the vehicle (1) at the end of the cycle having a predetermined duration.
