Solution Overview
Problem
Existing headlight beam setter devices are limited to passive regulation of vehicle headlights and lack communication with intelligent optical systems and other advanced driver assistance systems (ADAS), requiring separate equipment for complete control and calibration.
Innovation Solution
A multifunctional unit that communicates with vehicle electronic systems via the OBD socket for wireless data reading and activation, incorporating a headlight beam setter device, laser alignment, and a portable display for comprehensive calibration and control of ADAS systems, including optical groups, cameras, radar, and infrared sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a headlight beam setter device is used for passive regulation of headlights, then the light beam orientation can be controlled, but communication with intelligent optical systems and ADAS is not possible
Solution Approach 1:
The calibration device is transformed from a dedicated headlight beam setter into a multifunctional unit that can communicate with various vehicle electronic systems including intelligent optical systems and ADAS. The OBD interface enables universal communication capability across different vehicle systems, allowing the same device to perform calibration for headlights, cameras, radar, and other sensors.
2Productivity
If separate equipment is used for headlight control and ADAS calibration, then each function can be specialized, but multiple devices are required for complete control
Solution Approach 1:
The patent combines headlight calibration functionality with ADAS calibration capabilities into a single integrated device. By merging the OBD communication interface, display unit, and calibration tools into one system, the device can perform both headlight beam setting and calibration of advanced driver assistance systems, eliminating the need for separate equipment.
3Ease of operation
If a fixed display unit is integrated in the headlight beam setter, then the structure is simplified, but the display cannot be conveniently accessed during adjustments
Solution Approach 1:
The display unit is designed to be movable rather than fixed, allowing it to be repositioned according to the user's needs during calibration operations. This dynamic configuration enables the display to be accessed conveniently while maintaining a relatively simple overall device structure, as the display can be moved to optimal viewing positions without requiring complex mounting mechanisms.
