Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of LEDs are used in the same brake light assembly, then the brake light can be adapted to different vehicle configurations and glass properties, but the optical lens performance becomes suboptimal because the lens is designed for a specific LED type
Solution Approach 1:
The support structure incorporates adjustable positioning mechanisms that allow the printed circuit board to be positioned at multiple predetermined distances from the optical lens. This dynamic adjustment capability enables the system to adapt to different LED types while maintaining optimal optical performance, as each LED type can be positioned at its specific focal distance from the lens.
Solution Approach 2:
The invention changes the positional parameter of the LED relative to the optical lens by providing multiple predetermined distances. By adjusting the distance parameter between the LED emitting face and the lens, the system optimizes optical performance for different LED types without requiring different lens designs.
2Reliability
If the brake light is designed for a specific LED type with optimized optical lens positioning, then optimal optical performance is achieved, but the device cannot accommodate different LED types without redesign
Solution Approach 1:
The support structure is designed with multiple predetermined positioning distances that can accommodate different LED types. This universal design allows a single brake light assembly to function optimally with various LED types by positioning each type at its specific focal distance, eliminating the need for multiple specialized designs.
Solution Approach 2:
The support structure is segmented into multiple positioning levels or distances, each optimized for a specific LED type. This segmentation allows the system to maintain optimal optical performance for each LED type while using a single unified lens design, as each segment corresponds to a specific focal distance requirement.
3Reliability
If multiple brake light devices are developed for different configuration variations, then optimal performance for each configuration is achieved, but production efficiency decreases and development costs increase
Solution Approach 1:
A single brake light device design with an adjustable support structure can accommodate multiple vehicle configurations and LED types. This universal design eliminates the need to develop and produce multiple specialized devices, thereby maintaining optimal performance across configurations while improving production efficiency and reducing development costs.
Solution Approach 2:
The dynamic positioning capability of the support structure allows one brake light device to be adapted to different configurations through adjustment rather than requiring multiple static designs. This reduces manufacturing complexity and inventory requirements while maintaining configuration-specific optimization.

AI summary
The invention provides a signaling and/or lighting device for a motor vehicle, in particular a brake light for the rear window of a motor vehicle, comprising a printed circuit board mounted on a substrate. The printed circuit board includes at least one light source, one emitting face of which is oriented towards an optical lens of the device, the emitting face generally being perpendicular to the optical axis of the lens. The substrate for the printed circuit board allows it to be mounted at a plurality of predetermined distances from the optical lens, thus ensuring the focusing of the light emitted by different types of light sources usable in the device.
