Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a standard nominal 4 inch circular lamp or traditional oval lamp is used, then the illuminated surface area requirement is met, but the space efficiency is reduced and design flexibility is limited
Solution Approach 1:
The lamp housing is divided into multiple functional zones: a red translucent cover area and a clear cover area, each containing specific LED emitters. This segmentation allows the red and clear illuminated areas to be positioned adjacently to form a contiguous illuminated surface, meeting area requirements while optimizing space utilization through targeted placement of light-emitting components in each zone.
Solution Approach 2:
The patent utilizes the two-dimensional plane of the lamp cover by positioning red and clear illuminated areas side-by-side, creating a contiguous illuminated surface that extends across adjacent regions. This dimensional arrangement allows the lamp to achieve required illuminated surface area without increasing the overall housing volume, as the illumination expands laterally rather than requiring additional depth or height.
2Adaptability or versatility
If traditional lamp designs with separate cavities for different functions are used, then functional requirements are met, but device complexity increases
Solution Approach 1:
The lamp housing is designed as a unified multi-functional structure where the red translucent cover and clear cover share common housing elements, mounting features, and electrical connections. The red and clear illuminated areas are integrated into a single lamp assembly that can fulfill multiple lighting functions (tail lights, brake lights, turn signals) without requiring separate dedicated lamps or complex multi-cavity structures, thereby reducing overall device complexity while maintaining functional versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design meets illuminated surface area requirements while providing a more space-efficient and aesthetically flexible solution that complies with regulatory standards, offering greater design flexibility and improved aesthetic options.
Implementation Method 1
A first LED light emitter located directly beneath the red first area. There also is included a white second LED light emitter located directly beneath the clear second area.
Implementation Method 2
a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area

AI summary
A lamp for the rear of a vehicle is disclosed with a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area. It has a first LED light emitter located directly beneath the red first area, a second LED light emitter located directly beneath the clear second area, and a third LED light emitter, also located directly beneath said clear second area. The third red LED light emitter is for emitting red light through the clear second area simultaneously with light transmitted through the red first area, whereby the first and second areas are adapted to collectively form a contiguous red illuminated surface area.
