Radar Bracket with Projecting Edges for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radar units installed on vehicle bumpers lack adequate protection from impact forces, which can cause damage during collisions.
Innovation Solution
A radar support structure featuring a radar bracket with a concaved area and projecting edges that house the radar unit, where the edges extend forward of the unit's surface to absorb and distribute impact forces, preventing direct damage to the radar unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the radar unit is installed directly on the bumper surface, then the installation structure is simple, but the radar unit lacks protection from impact forces
Solution Approach 1:
The radar unit is nested within a concaved area of the radar bracket, which is itself attached to the bumper. This nested structure allows the radar unit to be protected by the bracket's projecting edges while maintaining a compact integration with the bumper assembly.
Solution Approach 2:
The radar bracket's projecting edges extend forward of the radar unit's front surface, creating a protective barrier before impact forces can reach the radar unit. This beforehand cushioning structure absorbs and distributes impact forces away from the radar unit.
2Reliability
If the radar bracket includes projecting edges that extend forward of the radar unit, then impact protection is improved, but the bracket structure becomes more complex
Solution Approach 1:
The radar bracket is segmented into distinct functional areas: a mounting surface for attaching the radar unit, a concaved area that houses the unit, and projecting edges that provide protection. This segmentation allows each part to perform its specific function while maintaining overall structural efficiency.
Solution Approach 2:
The radar bracket exhibits local quality by having different structural characteristics in different regions: the mounting surface provides attachment functionality, the concaved area provides housing and alignment, and the projecting edges provide impact protection. Each region is optimized for its specific purpose.
3Reliability
If the concaved area with mounting surface is designed to house the radar unit, then protection and alignment are improved, but manufacturing complexity increases
Solution Approach 1:
The mounting surface and concaved area are merged into a single integrated radar bracket structure rather than being separate components. This merging simplifies manufacturing by requiring only one fabrication process while still providing both the housing function and the precise mounting surface for the radar unit.

AI summary
A radar support structure includes a front bumper assembly, a radar bracket and a radar unit. The front bumper assembly has a support bracket, an energy absorbing member and a facia member attached to forward portions of a vehicle. The support bracket has a surface spaced apart from the energy absorbing member. The radar bracket is fixed to the surface of the support bracket and extends away from the energy absorbing member. The radar bracket includes two edge portions with a concaved area defining a mounting surface being located between the two projecting edges. The radar unit is installed to the mounting surface within the concaved area such that the two edge portions are located forward of a front most surface of the radar unit.
