Motorcycle Radar Placement Below Front End for Protected Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radar devices in straddle vehicles are vulnerable to damage from flying objects when exposed, and integrating them within the front cowling restricts design freedom, increasing aerodynamic resistance and aesthetic appeal.
Innovation Solution
A straddle vehicle design that positions the radar device below the front end of the vehicle body, covered by a radar cover that allows electromagnetic signal transmission and reception while maintaining design freedom and reducing aerodynamic resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar device is arranged within the front cowling, then the radar device is protected from flying objects, but the degree of freedom in designing the outer shape of the front cowling is reduced and aerodynamic resistance increases
Solution Approach 1:
The radar device is extracted from the front cowling and positioned separately below the front end portion of the vehicle body. This allows the front cowling to maintain its original aerodynamic shape without accommodation modifications, while the radar device remains protected by its own dedicated cover structure.
Solution Approach 2:
The protection function is segmented from the front cowling to a dedicated radar cover. The front cowling focuses on aerodynamic and aesthetic functions, while the radar cover provides protection for the detecting device. This functional segmentation resolves the conflict between protection and design freedom.
2Reliability
If the radar device is arranged within the front cowling, then the radar device is protected from flying objects, but aerodynamic resistance increases
Solution Approach 1:
The radar device is extracted from the front cowling and positioned separately below the front end portion of the vehicle body. This allows the front cowling to maintain its original aerodynamic shape without accommodation modifications, while the radar device remains protected by its own dedicated cover structure.
Solution Approach 2:
The radar device is positioned in a different spatial dimension (below the front end portion) rather than within the front cowling's volume. This dimensional relocation allows the front cowling to maintain its streamlined shape while the radar device occupies a separate space that does not interfere with aerodynamic flow.
3Reliability
If the radar device is covered by a front cowling, then the radar device is protected from flying objects, but the placement of the detecting device increases the outer shape of the upper portion of the front cowling
Solution Approach 1:
The radar device is extracted from the front cowling and positioned separately below the front end portion of the vehicle body. This allows the front cowling to maintain its original aerodynamic shape without accommodation modifications, while the radar device remains protected by its own dedicated cover structure.
