Vehicle Radar Mount With Spring-Guided Cover Clearance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radar systems face design challenges due to the need for a large radar cover to prevent interference with signal transmission, which compromises the exterior design of vehicles and increases the risk of damage during frontal collisions.
Innovation Solution
A radar support device with a bracket, guide rods, fastening members, and springs that adjust the distance between the radar and its cover, allowing the radar to move forward and maintain proximity to the cover, reducing the size of the radar cover and enhancing vehicle design while ensuring operational integrity during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar is mounted at a position spaced 30 mm or more backward from the radar cover to maintain operation during frontal collision, then the radar can maintain operation in collision situations, but the radar cover needs to be larger to prevent interference with radar signals, leading to deterioration of exterior design
Solution Approach 1:
The radar is designed to move dynamically between a first position (spaced from the cover) and a second position (close to the cover) based on collision detection. The support device includes a moving mechanism that transitions the radar between these positions, allowing the cover size to be reduced while maintaining collision reliability through automatic position adjustment.
Solution Approach 2:
A support device acts as an intermediary between the radar and the vehicle body, providing controlled movement capability. This intermediary mechanism enables the radar to achieve both positions (far and close to cover) as needed, resolving the conflict between cover size and collision reliability requirements.
2Area of stationary object
If the radar is mounted closer to the radar cover to reduce the cover size, then the exterior design is improved and cover size is minimized, but the radar may not maintain operation in frontal collision situations
Solution Approach 1:
The system uses dynamic position adjustment where the radar can be located close to the cover during normal operation (improving design) but automatically moves to a safer position when collision is detected (maintaining reliability). This dynamic behavior resolves the static contradiction between cover size and collision safety.
Solution Approach 2:
The radar support device is pre-configured with movement capability and collision detection functionality, allowing the radar to proactively move to a safe position before collision damage occurs. This preliminary preparation ensures reliability without requiring the radar to be permanently positioned far from the cover.

Function Achieved in This Case
The solution reduces the size of the radar cover, minimizes damage risk, and maintains radar functionality by positioning the radar close to the cover, thereby improving vehicle aesthetics and preventing secondary accidents.
