Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of sensors on vehicles, such as cameras and LiDAR, complicates assembly and requires careful consideration of heat dissipation, wiring, and sensor field of view, leading to potential blockages and data collection issues.
Innovation Solution
A bracket system with symmetrically arranged connecting pieces for image sensors and LiDAR above the A pillars of a vehicle, integrated with a cast aluminum connecting body, allows for optimal sensor placement, reducing blind zones and assembly difficulties while accommodating additional components like brake lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors (cameras, LiDAR, radars) are added to the vehicle to enhance ADAS capabilities, then the sensor detection coverage and functionality are improved, but the assembly difficulty on the production line increases and space requirements for structural design are expanded
Solution Approach 1:
The patent integrates multiple sensors (image sensors, LiDAR, radars) and their mounting structures into a unified bracket assembly. The bracket body serves as a common platform that consolidates what would otherwise be separate mounting operations, thereby reducing assembly difficulty while maintaining comprehensive sensor detection coverage.
Solution Approach 2:
The bracket assembly is designed as a multi-functional component that simultaneously mounts various types of sensors (cameras, LiDAR, radars) and accommodates their respective requirements for positioning, heat dissipation, and wiring. This universal structure eliminates the need for separate mounting solutions for each sensor type.
2Reliability
If multiple sensors are added to the vehicle, then the ADAS functionality is enhanced, but the space requirements for structural design increase
Solution Approach 1:
The bracket assembly employs a nested structure where smaller sensor mounting components are integrated within or attached to the main bracket body. The connecting pieces and sensor mounts are arranged to utilize the three-dimensional space efficiently, with components nested or closely integrated rather than distributed across large areas.
Solution Approach 2:
The patent transitions from two-dimensional sensor placement on flat surfaces to three-dimensional arrangement using vertical space and multiple levels. The bracket body extends in multiple dimensions, allowing sensors to be positioned at different heights and angles, thereby reducing the horizontal footprint while maintaining detection coverage.
3Reliability
If sensors are arranged on the vehicle roof, then the sensor field of view is improved, but the assembly complexity and structural design challenges increase
Solution Approach 1:
The bracket assembly is divided into modular segments including a main bracket body and multiple connecting pieces. Each connecting piece is designed to mount specific sensors, allowing for standardized assembly procedures. This segmentation enables workers to assemble different sensor configurations using the same basic bracket structure, reducing overall assembly complexity.
