Auxiliary Installation Tool for Vehicle Radar Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the vehicle radar industry is accurately locating the angular and positional relationship between the vehicle and the radar device for proper installation, as each car model requires unique alignment, leading to difficulties in passing verification testing due to potential biases in installation angle or position.
Innovation Solution
An auxiliary installation tool featuring an angle ruler with a first reference section aligned with the vehicle body horizontal line, a second reference section aligned with or parallel to the vehicle rear horizontal line, and a radar installation section, allowing for the determination of the correct radar installation angle without the need for precise instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional radar installation methods are used without auxiliary tools, then installation flexibility is maintained, but measurement precision and alignment accuracy deteriorate
Solution Approach 1:
The patent introduces an auxiliary installation tool as an intermediary device between the installer and the radar system. This tool includes a protractor component that mediates the measurement process, allowing accurate angle determination without requiring complex precision instruments. The protractor serves as a mediator that simplifies the measurement task while maintaining high accuracy.
Solution Approach 2:
The patent creates a simplified copy or representation of the measurement function through the auxiliary tool. Instead of using complex precision instruments, the tool provides a simplified protractor-based measurement system that replicates the essential measurement capability at a lower complexity level, making it accessible for standard installation procedures.
2Manufacturing precision
If precise measurement tools are used for radar installation, then alignment accuracy is improved, but installation time and cost increase
Solution Approach 1:
The patent employs a simple, inexpensive auxiliary installation tool that can be easily discarded after use. The protractor-based tool is designed to be a low-cost, single-use or reusable item that provides sufficient precision for installation without requiring expensive precision instruments. This approach reduces both the time and cost associated with manual inspection while maintaining adequate alignment accuracy.
3Reliability
If standardization of radar installation is implemented, then verification testing compliance is improved, but adaptability to different car models deteriorates
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism in the auxiliary installation tool that allows the protractor to be rotated and positioned according to the specific requirements of different car models. This dynamic capability enables the same standardized tool to adapt to various installation scenarios while maintaining compliance with verification testing requirements through consistent measurement methodology.

AI summary
An auxiliary installation tool for a vehicle radar (12) includes an angle ruler. The angle ruler includes a first reference section (110), a second reference section (120), and a radar installation section (130). The first reference section and the second reference section are connected and intersect at a right angle, wherein during measurement, the first reference section is configured for aligning with a vehicle body horizontal line H, the second reference section is configured for aligning with or parallel to a vehicle rear horizontal line L, the vehicle body horizontal line and the vehicle rear horizontal line respectively extend along the body and the rear of a vehicle and intersect at a corner of the vehicle (10). The radar installation section is correspondingly located at the corner of the vehicle, and the radar installation section and the second reference section are connected and intersect at a radar installation angle.
