Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light sources are arranged in multiple rows to improve light efficiency and beam pattern formation, then illumination performance is improved, but the external design becomes bulkier and less slim
Solution Approach 1:
The patent transforms the traditional multi-row light source arrangement (occupying vertical space) into a single-row arrangement where light is redirected through reflective surfaces. The guiding modules use reflection to redirect light from a single row of light sources to form the desired beam pattern, effectively moving the light redirection function from the vertical dimension to the horizontal dimension through optical paths.
Solution Approach 2:
The patent introduces guiding modules as intermediary components between the light sources and the external environment. These guiding modules contain reflective surfaces that act as mediators to redirect light from the incident part to the emission part, enabling single-row light sources to achieve beam patterns traditionally requiring multiple rows, thus maintaining a slim external design.
2Loss of energy
If guiding modules use reflective surfaces to redirect light, then light efficiency is improved, but device complexity increases
Solution Approach 1:
The guiding modules serve multiple functions simultaneously: they contain reflective surfaces for light redirection, define the beam pattern geometry, and structure the single-row light source arrangement. This multi-functionality reduces the need for separate components for each function, thereby managing device complexity while improving light efficiency.
Solution Approach 2:
The patent optimizes the geometric parameters of the guiding modules, including the angles and positions of reflective surfaces, to maximize light redirection efficiency. By carefully designing these parameters, the system achieves high light efficiency without requiring overly complex structures, as the optimized geometry naturally guides light along efficient paths.

AI summary
A vehicle lamp includes a plurality of light sources that generate light; a first lens part including a plurality of guiding modules that adjust paths of the light emitted from the plurality of light sources, respectively; and a second lens part through which the light emitted from the first lens part is transmitted to form a predetermined beam pattern. Each of the plurality of guiding modules includes an incident part on which the light emitted from a corresponding light source among the plurality of light sources is incident; an emission part through which the light incident on the incident part is emitted; and a transfer part that guides the light incident on the incident part toward the emission part, and the plurality of light sources are arranged to form at least one row that extends in a left-right direction.
