Vehicle Radar Mount Bracket with Deformable Shock Absorbing Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional radar mounting structures on vehicles face challenges in achieving both shock absorbability and detectability, as they either deform excessively under collision, damaging nearby components or fail to absorb impact adequately when made stiffer.
Innovation Solution
A mounting structure featuring a cross linking member with a fixing member, a supporting part for the radar device, and deformable parts that bend to absorb shock, allowing the radar to be positioned close to the bumper for enhanced detectability while absorbing impact loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bracket stiffness is increased to suppress deformation, then the radar device protection is improved, but the collision load absorption capability deteriorates
Solution Approach 1:
The bracket is divided into a rigid portion (for mounting the radar device) and a flexible portion (for absorbing collision energy). This segmentation allows different parts of the same component to have different stiffness characteristics, enabling simultaneous protection of the radar device and absorption of collision loads.
Solution Approach 2:
Different regions of the bracket are designed with different mechanical properties: the rigid portion near the radar mounting area maintains high stiffness for device protection, while the flexible portion extending toward the bumper allows deformation for energy absorption. This local differentiation of material properties resolves the contradiction between protection and energy absorption.
2Loss of energy
If the bracket is made more flexible to absorb collision, then the shock absorbability is improved, but the radar device stability deteriorates
Solution Approach 1:
The bracket structure is segmented into distinct rigid and flexible portions, where the rigid portion ensures radar device stability while the flexible portion provides shock absorbability. This segmentation allows each portion to perform its specialized function without compromising the other.
Solution Approach 2:
The flexible portion acts as an intermediary element between the rigid bracket and the bumper, absorbing collision energy before it reaches the radar device. This intermediary structure protects the stable radar mounting while enabling energy dissipation.
3Measurement precision
If the radar device is positioned closer to the bumper, then the detectability is improved, but the vulnerability to collision damage increases
Solution Approach 1:
The flexible portion of the bracket serves as a mediator between the radar device and the bumper, allowing the radar to be positioned close to the bumper for improved detectability while the flexible portion absorbs collision energy to protect the radar from damage.
Solution Approach 2:
The flexible portion is designed in advance to deform and absorb collision energy before it can reach the radar device. This beforehand cushioning mechanism allows the radar to be positioned close to the bumper while being protected from collision damage.

AI summary
In a structure for mounting a radar, a cross linking member (3) vertically connects two width-across members (1,2) aligned in a front-to-rear direction of a vehicle. A fixing member (4) is fixed to the cross linking member (3). The fixing member (4) includes a fixing part (5) fixed to the cross linking member (3), a supporting part (6) that supports a radar device (10), a deformable part (7). The deformable part (7) has a shape connecting the fixing part (5) and the supporting part (6) and bends and deforms to absorb shock when an external force is input into the radar device (10).
