Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicle lighting devices face challenges in maximizing recognizability and energy efficiency due to cramped arrangements of lighting elements, which limits their size and effectiveness in forming distinct lighting units.
Innovation Solution
A lighting device with a housing containing four lighting elements arranged in a rectangular configuration, where two upper and two lower elements are connected by webs, allowing for a larger illuminated area and energy-efficient LED implementation, with optional additional linear lighting elements and a frame-like enclosure for enhanced visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lighting elements are arranged in a cramped configuration to fit multiple lights in a housing, then the housing can accommodate multiple lighting functions, but the size of individual lighting elements becomes smaller and recognizability is reduced
Solution Approach 1:
The patent divides the lighting system into distinct lighting units, each with specific lighting elements arranged in particular patterns (e.g., rectangular arrangements of four elements). This segmentation allows each unit to maintain its functional identity and recognizability while contributing to the overall versatility of the housing.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of lighting elements within the housing, creating depth and vertical positioning (upper and lower lighting elements). This dimensional approach allows multiple lighting functions to coexist without compromising the visual impact of individual elements.
2Adaptability or versatility
If lighting elements are made smaller to fit more in the housing, then more lighting functions can be implemented, but energy efficiency and effectiveness are reduced
Solution Approach 1:
The patent combines multiple lighting elements into integrated lighting units with shared structural support and common mounting mechanisms. This merging reduces overall system complexity and energy consumption while maintaining multiple lighting functions through coordinated operation of the unified units.
3Illumination intensity
If lighting elements are arranged in a rectangular configuration with connecting webs, then the illuminated area is enhanced and recognizability is improved, but the device complexity increases
Solution Approach 1:
The patent employs universal mounting structures and standardized connecting web designs that can be applied across different lighting units and configurations. This universality reduces the actual complexity despite the rectangular arrangements, as the same structural principles are reused throughout the system.
