Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radar device mounting structures on vehicles suffer from limited layout configurations, reduced detection accuracy, and difficulties in maintenance due to protruding positions and lack of easy access.
Innovation Solution
A mounting structure that includes a support bracket attached to the vehicle body to support the radar device in the object detection direction and a cover member fixed to the support bracket, housing the radar device in a chamber to protect it from water and facilitate easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the radar device is disposed protruding below the lamp chamber, then the mounting structure is simple, but the detection accuracy cannot be sufficiently improved and the layout configuration is limited
Solution Approach 1:
The patent transitions from a one-dimensional protruding mounting below the lamp chamber to a three-dimensional integrated housing chamber that encompasses the radar device. The cover member and support bracket form a enclosed space that positions the radar device optimally in multiple spatial dimensions, improving detection accuracy while maintaining structural simplicity.
2Device complexity
If the radar device is disposed protruding below the lamp chamber, then the mounting structure is simple, but the layout configuration of the radar device is limited
Solution Approach 1:
The mounting structure is segmented into distinct functional components: the support bracket for structural support and positioning, the cover member for protection and enclosure, and the integrated housing chamber for radar device accommodation. This segmentation allows each component to be independently designed and optimized, providing greater layout flexibility while keeping the overall structure simple.
3Device complexity
If access to the radar device is not easy, then the mounting structure is compact, but it takes time and effort to replace or maintain the radar device
Solution Approach 1:
The housing chamber acts as an intermediary structure that provides protected access to the radar device. The cover member serves as a removable intermediary that can be taken off to access the radar device for maintenance, while maintaining a compact integrated structure during normal operation. This resolves the contradiction by providing both compactness and maintenance accessibility.
4Device complexity
If a part of the radar device is not covered, then the mounting structure is simple, but the radar device may be submerged by rainwater or the like
Solution Approach 1:
The support bracket and cover member are merged to form an integrated housing chamber that completely encloses the radar device. This unified structure provides comprehensive water protection while maintaining simplicity, as the merged components create a sealed environment without requiring additional protective elements.
