Vehicle Radar Bracket Assembly for Impact Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radar assemblies in vehicles are not effectively protected from damage during external impacts, as they are rigidly attached and lack mechanisms to absorb energy and reposition the radar unit after deformation.
Innovation Solution
A radar assembly design featuring a movable second bracket that pivots between a rest and deformed position, supported by a first bracket and a deformable energy absorption member, allowing the radar unit to absorb impact energy and reposition itself, utilizing a hinge pin and torsion springs for biasing and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar unit is rigidly attached to the vehicle body structure, then the radar unit maintains stable positioning, but the radar unit is vulnerable to damage during external impacts
Solution Approach 1:
The patent introduces a movable bracket and energy absorption member that are pre-configured to cushion and absorb impact energy before it reaches the radar unit. The movable bracket is designed to deform and the energy absorption member is positioned to compress during impact, providing beforehand cushioning that protects the radar unit from damage while maintaining stable positioning during normal operation
2Reliability
If the radar unit is rigidly attached to the vehicle body structure, then the radar unit maintains fixed positioning, but the radar unit cannot absorb impact energy or reposition after deformation
Solution Approach 1:
The patent transforms the static, rigid bracket structure into a dynamic system with a movable bracket that can change position and deformation state. The movable bracket is connected to the vehicle body through a mechanism that allows controlled movement and deformation during impact, enabling the system to adapt to impact forces while maintaining positioning during normal operation. This dynamic approach allows energy absorption and repositioning capabilities without excessive structural complexity

AI summary
A radar assembly includes a front bumper assembly, a radar support structure and a radar unit. The front bumper assembly has a support bracket. The radar support structure has first bracket that is fixed to the support bracket. The radar support structure second bracket is movable relative to the first bracket and the support bracket between a rest position and a deformed position. The radar unit is supported to the second bracket to move with the second bracket relative to the first bracket and the support bracket.
