Vehicle LIDAR Headlamp Integration via Optical Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing installation of head lamps and LIDAR in vehicles requires separate spaces and components, leading to increased space and cost, as well as the need to adjust installation positions if either function is compromised.
Innovation Solution
A lidar integrated lamp apparatus that combines the functions of a head lamp and LIDAR in a single space using a first light source for forming a beam pattern, a second light source for LIDAR detection, a reflection unit to direct lights from different paths, and a control unit to manage the irradiation angles and ON/OFF states of the light sources, allowing for shared installation space and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If head lamp and LIDAR are installed separately, then each function can be independently optimized, but the installation space and component quantity increase
Solution Approach 1:
The patent combines the head lamp and LIDAR into a single integrated apparatus where both functions share the same installation space. The housing contains both the head lamp unit and LIDAR unit, allowing them to be mounted together as one component rather than requiring separate installation locations on the vehicle.
Solution Approach 2:
The integrated apparatus serves multiple functions simultaneously - it provides both headlamp illumination and LIDAR detection capabilities. The single apparatus is designed to perform both lighting and distance detection functions, reducing the need for separate dedicated components.
2Adaptability or versatility
If head lamp and LIDAR are installed separately, then each can have its own optimal position, but the number of components and installation complexity increase
Solution Approach 1:
The patent merges the head lamp and LIDAR into a single integrated unit with a common housing and mounting structure. This reduces the component count from two separate assemblies to one unified apparatus, simplifying installation while maintaining functional independence through internal separation of the two units.
3Area of stationary object
If head lamp and LIDAR share the same installation space, then layout is reduced, but the light paths may interfere with each other
Solution Approach 1:
The integrated apparatus divides the internal space into distinct segments - one for the head lamp unit and another for the LIDAR unit. This spatial segmentation allows each component to have its own dedicated light path without interference from the other, even though they share the same external housing and mounting location.
Solution Approach 2:
The patent uses reflective surfaces and optical guides as intermediaries to direct light from each source along separate paths. The head lamp light and LIDAR light are channeled through different optical pathways within the housing, preventing interference while allowing both to exit through the same general direction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the layout and cost by integrating both functions in one space, maintaining functionality while minimizing the need for separate installations and optimizing irradiation angles for both head lamp and LIDAR operations.
Implementation Method 1
a reflection unit provided between the first light source and the second light source and configured to turn traveling paths of the light for forming the beam pattern and the light for being detected by the lidar
Implementation Method 2
a reflection mirror provided behind the reflection unit and configured to turn the light for forming the beam pattern or the light for being detected by the lidar, which are directed backward by the reflection unit, to again direct forward
Data Source
AI summary
In the Light Detection and Ranging (LIDAR) integrated lamp apparatus of a vehicle, an application location for a head lamp and an application location for a ladder are configured in the same space, with the result that layout is reduced and the cost reduction due to reduction of the number of the associated portions is achieved by sharing and combining components.
