Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headlamps with slimmed designs face challenges in maintaining optical efficiency, which degrades their ability to form targeted beam patterns, making it difficult to achieve effective light distribution.
Innovation Solution
The lamp incorporates an optic module with a light source and optic lens that refract light to reduce upward/downward orientation angles, and a refraction lens that reduces leftward/rightward orientation angles, forming specific beam patterns through a combination of convex and parallel curvatures on the lens surfaces, allowing for targeted light distribution without degrading optical efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional optical parts are manufactured to be slimmed, then aesthetic appearance is improved, but optical efficiency is degraded
Solution Approach 1:
The optical system is divided into multiple independent optical parts: a first optical part (collimator) that concentrates light from the light source, and a second optical part (projection lens) that forms the beam pattern. This segmentation allows each component to be optimized for its specific function while maintaining overall slimmed design, preventing energy loss that would occur in a single integrated slimmed component.
Solution Approach 2:
The patent employs curved optical surfaces including a convex forward-facing optic light output surface and a concave rearward-facing lens light input surface. These curved geometries are essential for effective light refraction and concentration, maintaining optical efficiency despite the reduced overall size of the headlamp assembly.
2Volume of moving object
If conventional optical parts are manufactured to be slimmed, then device size is reduced, but light distribution performance is degraded
Solution Approach 1:
By separating the optical system into distinct collimating and projecting components, each can be miniimized in size while performing its specific function effectively. The collimator concentrates light efficiently in a compact form, and the projection lens creates the desired beam pattern, together achieving targeted light distribution in a reduced overall volume.
Solution Approach 2:
Different regions of the optical components have different curvatures and refractive properties optimized for their local function. The optic lens has an upward/downward curvature on its light output surface for vertical light control, while the refraction lens part has a leftward/rightward curvature for horizontal light control, enabling precise local light distribution despite compact overall dimensions.
3Shape
If optical efficiency is rapidly degraded, then slimmed design is achieved, but targeted beam pattern formation becomes difficult
Solution Approach 1:
The optical system is divided into specialized components with dedicated functions: the collimator handles light concentration, while the projection lens handles beam pattern formation. This functional segmentation allows each component to be simplified in design while collectively achieving complex beam patterns, resolving the contradiction between simplicity for slimmed design and complexity for beam pattern capability.
