Rear V2X Antenna Integration in Aerodynamic Deflector Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in installing V2X antennas to cover the rear area without modifying the vehicle's structure, due to limited space and the need for directional coverage.
Innovation Solution
A V2X antenna is placed in the free space between a rear aerodynamic deflector and a structural element, using a clipping mechanism with a lining that has parallel slides and elastically deformable fixing tabs to secure the antenna, allowing for precise positioning without altering the deflector's orientation or aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a V2X antenna is installed on the rear facade of the vehicle, then rear area coverage is achieved, but the vehicle structure must be modified
Solution Approach 1:
The V2X antenna is nested within the existing aerodynamic deflector structure by utilizing the free space between the deflector and the structural element. The antenna is housed behind the aerodynamic deflector, effectively nesting it within the existing vehicle components without requiring external modifications or structural changes.
2Ease of operation
If the aerodynamic deflector position is modified to accommodate the antenna, then antenna installation is enabled, but aerodynamic efficiency is compromised
Solution Approach 1:
Instead of modifying the deflector's external position or orientation, the solution utilizes the internal free space dimension between the deflector and the structural element. The antenna is installed in this previously unused spatial dimension, allowing installation without altering the deflector's external aerodynamic profile.
3Reliability
If directional antennas are placed all around the vehicle for 360° coverage, then environmental awareness is improved, but available installation space is reduced
Solution Approach 1:
The solution applies local quality by utilizing the specific free space located between the aerodynamic deflector and the structural element on the rear facade. This localized space, which was previously unused, is specifically targeted for antenna installation, allowing 360° coverage without requiring additional overall vehicle space.
