Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate light sources are used for longitudinal and lateral sidelights, then the luminous beam requirements are met, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent combines the longitudinal and lateral sidelight functions into a single integrated light source assembly. The reflector body and lenticular body work together with one light source to produce both beam types, eliminating the need for separate light sources and reducing component count while maintaining compliance with luminous beam requirements
Solution Approach 2:
The single light source is designed to perform multiple functions simultaneously - generating both longitudinal and lateral sidelight beams. The optical system (reflector + lenticular body) is configured to direct light in multiple directions to satisfy different sidelight requirements from one light source
2Reliability
If multiple light sources are used, then the sidelight functions are achieved, but the energy consumption increases
Solution Approach 1:
By merging the longitudinal and lateral sidelight generation into a single light source system, the patent reduces total energy consumption. One light source replaces what would traditionally require two separate light sources, directly lowering the energy required while still fulfilling both sidelight functions through optimized optical design
3Reliability
If separate light sources are used for longitudinal and lateral sidelights, then the beam geometry requirements are met, but the assembly cost increases
Solution Approach 1:
The patent merges the assembly requirements by designing an integrated optical system where one light source, one reflector body, and one lenticular body work together. This single assembly unit reduces the number of parts to be sourced, managed, and assembled, directly lowering assembly costs while maintaining precise beam geometry control through the coordinated optical elements

AI summary
A vehicle light (4) comprising a container body (8) and a lenticular body (12), hosting at least one light source (20), a light guide (40) having a light guide body (44) to propagate the beam of light of the light source (20). The light guide body (44) extends from a lateral end (52) to a longitudinal end (56); at the lateral end (52) the light guide (40) emits a transversal beam of light, directed in a transversal direction (Y-Y) and at the longitudinal end (56) the light guide (40) emits a longitudinal beam of light, according to a direction of advancement (X-X). The light source (20) is situated near said lateral end (52). At said lateral and longitudinal ends (52, 56) the light guide (40) comprises first and second light deviation/extraction elements (60) which extract the light from the light guide (40) in a respectively substantially transversal (Y-Y) and longitudinal direction (X-X).
