Vehicle Radar Unit Grille Mounting for Cone Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radar units mounted directly to a reinforcement beam in vehicles are prone to damage and emit a large radar cone due to their rearward position relative to the grille assembly, requiring additional protective structures and larger radome emblems.
Innovation Solution
A radar unit assembly where the radar unit is connected to a grille assembly with a mounting receptacle and covered by an emblem, allowing the radar unit to be positioned closer to the grille and reducing the radar cone diameter, thus eliminating the need for additional protective structures and larger emblems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar unit is mounted directly to a reinforcement beam extending in a lateral direction of the vehicle and disposed rearward of a grille assembly, then the radar unit is protected from damage by the grille assembly, but the radar unit is disposed significantly rearward of the grille assembly resulting in a large radar cone requiring a large radome emblem
Solution Approach 1:
The patent transitions the radar unit mounting from a lateral reinforcement beam to a forward-facing position on the grille assembly, changing the spatial dimension of installation. This dimensional shift allows the radar unit to be positioned at the front of the vehicle rather than rearward, thereby reducing the radar cone diameter while maintaining protection through the grille structure and emblem.
2Length of moving object
If the radar unit is mounted directly to a reinforcement beam extending in a lateral direction of the vehicle, then the radar unit is disposed significantly rearward of the grille assembly, but additional structure is required to protect the radar unit from damage
Solution Approach 1:
The patent merges the radar unit mounting with the grille assembly structure itself, rather than using a separate reinforcement beam. The radar unit is mounted to the grille assembly with the emblem serving as both a cosmetic cover and a protective element. This consolidation eliminates the need for additional protective structures while reducing the distance from the grille assembly.
3Area of stationary object
If the radar unit is disposed significantly rearward of the grille assembly, then a large radome emblem on the grille assembly is required to allow the radar cone to pass therethrough, but connecting the radar unit to the grille assembly reduces the radar cone diameter
Solution Approach 1:
The patent changes the key parameter of radar unit position from rearward to forward-mounted on the grille assembly. This parameter change directly reduces the radar cone diameter, allowing for a smaller emblem size while maintaining the necessary radar functionality and signal transmission through the emblem material.
