Vehicle Radar Sensor Mounting for Flexible Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radar sensors for vehicle movable parts are costly and require complex mounting brackets, limiting their orientation flexibility and increasing installation complexity.
Innovation Solution
A radar sensor with integrated mounting sections allowing direct attachment to a vehicle body, enabling various tilt angles and orientations without the need for additional brackets, using fastening tabs and ribs for stable, cost-effective installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a radar sensor with two detection ranges is used to detect gestures, then gesture detection capability is improved, but the cost and device complexity increase due to requiring multiple mounting brackets and complex installation
Solution Approach 1:
The patent combines multiple mounting functions into a single integrated mounting bracket that provides both the first detection range (for gesture recognition) and the second detection range (for vehicle status monitoring) through unified structural elements, eliminating the need for separate mounting brackets for each function
Solution Approach 2:
The mounting bracket is designed with universal multi-functionality to serve multiple purposes: it provides structural support for the radar sensor, enables gesture detection through specific angular orientations, and facilitates vehicle status monitoring through alternative mounting configurations, thereby replacing multiple specialized components with one versatile solution
2Measurement precision
If the radar sensor is mounted at an angle of 30 degrees to the ground for kick gesture detection, then gesture detection accuracy is improved, but the ease of installation deteriorates due to the need for precise angular positioning
Solution Approach 1:
The mounting bracket is pre-configured with predetermined angular orientations (including the 30-degree angle for kick gesture detection) during manufacturing, allowing installers to simply select and attach the bracket without performing complex angular positioning or calculations during installation
Solution Approach 2:
The mounting bracket offers multiple discrete angular orientations as standardized parameters, enabling the system to switch between different detection modes (kick gesture at 30 degrees, hand gesture at different angles) by selecting the appropriate pre-configured orientation rather than adjusting continuous angles
3Reliability
If mounting brackets are used to attach the radar sensor to the vehicle bumper, then the radar sensor can be securely mounted, but the cost and manufacturing complexity increase
Solution Approach 1:
The mounting functions are merged into the radar sensor housing itself through integrated mounting elements (such as attachment points or integrated brackets) that are manufactured as part of the housing, eliminating the need for separate mounting bracket components and reducing overall manufacturing complexity
Solution Approach 2:
The radar sensor housing is designed with self-contained mounting capabilities through integrated attachment points and fastening mechanisms that are part of the housing structure, allowing the housing to serve its own mounting needs without requiring external mounting brackets
