Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems are costly and complex due to large slider block assemblies and limited arrangements, and they often fail to effectively adjust light beams to prevent dazzling other drivers during uneven driving conditions.
Innovation Solution
A vehicle lighting assembly with a primary adjustment part and levers that allow cooperative movement of optical systems, including a tuning system for independent adjustment of reflectors, reducing weight and complexity while enabling horizontal arrangements of light beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large slider block assemblies are used to adjust light beams, then the lighting system can achieve beam leveling functionality, but the device complexity and production cost increase significantly
Solution Approach 1:
The lighting assembly is divided into multiple independent optical systems (first, second, third optical systems) that can be adjusted independently. Each optical system has its own adjustment mechanism, allowing the complex beam leveling function to be broken down into simpler, manageable segments rather than requiring a single large slider block assembly
Solution Approach 2:
The patent employs adjustable and movable components including arms that can pivot, optical systems that can be repositioned, and a curved slot mechanism that allows dynamic adjustment of reflector positions. This dynamic design replaces static large slider block assemblies with lighter, movable components that achieve the same beam leveling effect
2Device complexity
If multiple optical systems are arranged in limited configurations, then the lighting system structure is simplified, but the ability to control light beams and prevent dazzling is reduced
Solution Approach 1:
The patent introduces a curved slot mechanism that adds a dimensional element to the reflector adjustment. The curved slot allows reflectors to move along an arc-shaped path, providing additional degrees of freedom for beam control. This enables precise light beam direction control without requiring complex multi-axis mechanical arrangements
Solution Approach 2:
The adjustable arms and pivot mechanisms serve multiple functions: they position reflectors, adjust beam direction, and enable both horizontal and vertical beam leveling. This multi-functionality allows the same structural elements to control multiple optical systems simultaneously, maintaining ease of operation while supporting complex light beam management
3Device complexity
If a single adjustment part controls multiple optical systems, then production costs and weight are reduced, but the precision of individual optical system adjustment may be compromised
Solution Approach 1:
While using a single primary adjustment part, the patent segments the adjustment function by providing separate arms (first arm, second arm, third arm) that can independently connect to different optical systems. Each arm can be independently positioned and adjusted, allowing precise control of individual optical systems even though they share a common adjustment mechanism
Solution Approach 2:
The arms act as intermediary elements between the single adjustment part and the multiple optical systems. Each arm provides a mechanical leverage and positioning function that translates the movement of the adjustment part into precise positioning of individual optical systems, maintaining adjustment precision while using a lighter single adjustment mechanism
