Solution Overview
Problem
Existing radar mounting systems for industrial vehicles face reliability issues due to high vibrations and shocks, which can compromise the accuracy and durability of sensing devices like radar and lidar systems when installed on industrial vehicles compared to passenger cars.
Innovation Solution
A fixing unit comprising a first and second bracket with snap-engaging lugs and retaining pins that securely attach the sensing device, acting as an interface to absorb mechanical stress and filter vibrations, ensuring accurate positioning and protection during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard radar mounting system is used, then the installation is simple and cost-effective, but the reliability deteriorates under high vibrations and shocks in industrial vehicle environments
Solution Approach 1:
The mounting system is divided into a first bracket and a second bracket that are separate components. The first bracket is attached to the vehicle while the second bracket holds the sensing device, allowing each bracket to be optimized for its specific function and reducing the impact of vibrations on the sensing device itself.
Solution Approach 2:
The two-bracket assembly acts as an intermediary structure between the vehicle and the sensing device. This intermediate mounting system filters out vibrations and shocks from the vehicle, protecting the sensing device while maintaining a relatively simple installation process.
2Measurement precision
If a rigid mounting system is used, then the space orientation accuracy is maintained, but the sensing device is more susceptible to vibration damage
Solution Approach 1:
The mounting system is designed beforehand to cushion against vibrations and shocks. The two-bracket configuration with fixing lugs creates a mounting structure that absorbs mechanical stress before it reaches the sensing device, while still maintaining the required spatial orientation accuracy.
Solution Approach 2:
The bracket assembly serves as a mediator that decouples the sensing device from direct vibration transmission while preserving the precise spatial orientation needed for accurate environmental sensing.
3Productivity
If the sensing device is directly mounted to the vehicle, then the installation is quick and easy, but the device is exposed to full mechanical stress
Solution Approach 1:
By segmenting the mounting system into two separate brackets with fixing lugs, the patent enables a relatively quick installation process while distributing mechanical stress across multiple components rather than concentrating it on the sensing device itself.
Solution Approach 2:
The two-bracket mounting system acts as an intermediary that protects the sensing device from direct exposure to mechanical stress while maintaining installation efficiency through a modular design that can be assembled relatively quickly.
