Vehicle Illumination Device Diagonal Optical Path Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination devices for vehicles face challenges in integrating multiple components into limited spaces, particularly in external mirrors, due to their rigid arrangement and vertical optical path, which restricts flexibility and space efficiency.
Innovation Solution
The illumination device incorporates a single optical component with multiple reflective surfaces and a mask, allowing light to be projected from one side and exiting from another, with the option to include a reflector unit that deflects the optical path transversely or diagonally, reducing the number of components and enabling compact installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple illumination device components are combined into one housing with a single axis arrangement, then the device structure is simplified and components are integrated, but the device becomes difficult to integrate into external mirrors due to limited space and rigid arrangement
Solution Approach 1:
The patent transitions from a single-axis vertical arrangement to a multi-dimensional configuration where the optical path can be arranged diagonally or parallel to the projection surface. The reflector unit enables the optical path to exit at different angles (transversely, diagonally, or parallel), allowing the device to adapt to various spatial constraints in external mirrors.
Solution Approach 2:
The patent introduces adjustability in the optical path configuration through the reflector unit, which can deflect light at different angles. This dynamic capability allows the illumination device to be integrated into external mirrors with limited space by adapting the optical path direction to available installation spaces.
2Ease of operation
If the optical path is arranged vertically perpendicular to the projection surface, then the illumination device can be directly integrated into external mirrors, but the arrangement is restricted by limited space and reduces installation flexibility
Solution Approach 1:
The reflector unit serves multiple functions: it can deflect the optical path transversely, diagonally, or parallel to the projection surface depending on the installation requirements. This multi-functionality allows the same illumination device to be integrated into various external mirror designs with different spatial constraints.
Solution Approach 2:
The patent enables the optical path to exit the illumination device in multiple directions (transverse, diagonal, parallel) rather than only vertically, providing adaptability to different installation spaces within external mirrors while maintaining ease of integration.
3Device complexity
If the illumination device is arranged perpendicular to the projection surface with a vertical optical path, then the optical components can be aligned on a single axis, but the device occupies more space and reduces space efficiency
Solution Approach 1:
By allowing the optical path to exit at different angles (transversely, diagonally, or parallel) rather than only vertically, the patent reduces the volume occupied by the illumination device while maintaining single-axis alignment of optical components through the reflector unit.
