Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for installing position detection devices like laser radar on vehicles face issues such as unsightly appearance, large blind zones, increased wiring, and heat dissipation challenges, particularly when installed at the roof or bumper, and bulkiness when integrated into vehicle lamps.
Innovation Solution
A lighting and detecting module that separates the light source assembly from the lighting and detection assemblies, using a light transmission component to transmit lighting and detecting light, with a fluorescent component for visible lighting and a heat sink for efficient heat dissipation, and infrared lasers for detection, allowing for miniaturization and integration within vehicle lamps while reducing blind zones and wiring complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the laser radar is installed at the roof of the vehicle, then the detection range is improved, but the appearance of the vehicle becomes unsightly and the short-range blind zone near the vehicle increases
Solution Approach 1:
The patent combines the laser radar with the vehicle lamp into an integrated lighting and detecting module. The light source assembly serves dual purposes: providing illumination while housing the position detection device. This merging eliminates the need for separate roof-mounted radar installations, maintaining vehicle appearance while enabling detection functions.
2Shape
If the laser radar is installed at the bumper position, then the appearance is maintained, but more wiring harnesses are added in the engine compartment and a cleaning system is required
Solution Approach 1:
By integrating the position detection device with the existing lamp structure, the patent eliminates the need for separate wiring harnesses and cleaning systems. The lamp's existing power and control wiring are utilized, and the sealed lamp housing provides protection without requiring additional cleaning mechanisms.
3Device complexity
If the laser radar is installed directly into the interior of the vehicle lamp, then the appearance is maintained and wiring is reduced, but the volume of the vehicle lamp increases and heat dissipation becomes more difficult
Solution Approach 1:
The patent segments the lamp structure into distinct functional regions: a light source assembly for illumination, a fluorescent component for wavelength conversion, and a detecting assembly for position detection. The heat sink is specifically designed to extract heat from the light source assembly, separating the heat dissipation function from the lighting function and enabling effective thermal management within the compact lamp housing.
4Device complexity
If the laser radar is installed directly into the interior of the vehicle lamp, then wiring is reduced, but the volume of the vehicle lamp increases
Solution Approach 1:
The patent nests the position detection device within the existing lamp housing structure. The light source assembly and detecting assembly are arranged in a compact configuration where components are nested within each other's spatial envelope. The heat sink and fluorescent component are integrated into the lamp's internal volume, utilizing otherwise wasted space and minimizing the overall lamp volume increase.
