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 and design flexibility are reduced
Solution Approach 1:
The lamp housing is divided into multiple compartments, each containing specific LED emitters for different functions (stop, tail, turn, backup). This segmentation allows each section to be optimized independently while collectively meeting the total illuminated surface area requirement, thereby maintaining design flexibility.
Solution Approach 2:
The patent transitions from traditional two-dimensional lamp designs to a three-dimensional multi-compartment structure with LED emitters positioned at different depths and angles. This dimensional change allows for more efficient use of internal space while maintaining or exceeding the required illuminated surface area, enabling greater design flexibility.
2Reliability
If separate dedicated lamps are used for stop, tail, turn, and backup functions, then functional reliability is improved, but device complexity increases
Solution Approach 1:
Multiple lamp functions (stop, tail, turn, backup) are merged into a single integrated lamp housing with multiple compartments. Each compartment contains LED emitters dedicated to specific functions, maintaining functional reliability while reducing the number of separate lamp assemblies needed.
Solution Approach 2:
The single lamp housing serves multiple functions simultaneously - stop lighting, tail lighting, turn signaling, and backup lighting - making it a universal component that replaces what would traditionally require multiple separate lamps, thereby reducing overall system complexity.
3Adaptability or versatility
If additive chromatic effects are used to alter color patterns, then color versatility is improved, but manufacturing precision requirements increase
Solution Approach 1:
Different compartments within the lamp housing are assigned specific LED emitter types with fixed color characteristics (red LEDs for stop/turn, white LEDs for backup). This local quality assignment ensures each section produces its intended color reliably without requiring complex additive chromatic effects, thereby reducing manufacturing precision requirements while maintaining color versatility.

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.
