Motorcycle Blind Spot Sensing in Mirror Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blind spot detection systems for two-wheeled vehicles fail to effectively cover all sides of the vehicle, particularly during cornering or leaning, and are prone to missed alerts due to vehicle speed limitations or environmental interference, posing a significant safety risk for riders.
Innovation Solution
A blind spot detection system with sensors on the left, right, and rear sides of the vehicle using the time of flight principle to measure distance, velocity, and angle, coupled with an alert indication unit to provide direction-specific alerts, ensuring comprehensive blind spot coverage and rider safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional blind spot detection devices are mounted on the vehicle, then blind spot detection function is provided, but the devices increase wind resistance and affect vehicle aesthetics
Solution Approach 1:
The blind spot detection device is integrated with the vehicle's side mirror assembly, combining the detection function with an existing aerodynamic component. The detection device is mounted within the side mirror housing structure, allowing it to benefit from the mirror's streamlined design while performing blind spot monitoring.
Solution Approach 2:
The side mirror assembly serves multiple functions: it provides the traditional mirror reflection function while simultaneously housing the blind spot detection device. This multi-functional integration allows the same structural component to serve both aesthetic/aerodynamic purposes and safety detection purposes.
2Reliability
If conventional blind spot detection devices are mounted on the vehicle, then blind spot detection function is provided, but the devices affect vehicle aesthetics
Solution Approach 1:
The blind spot detection device is integrated with the vehicle's side mirror assembly, combining the detection function with an existing aerodynamic component. The detection device is mounted within the side mirror housing structure, allowing it to benefit from the mirror's streamlined design while performing blind spot monitoring.
Solution Approach 2:
The detection device is positioned within the side mirror housing, utilizing the existing contours and surfaces of the mirror assembly. This local integration ensures the detection device conforms to the vehicle's overall aesthetic design language while maintaining its functional capabilities.
3Reliability
If multiple detection devices are installed to improve detection accuracy, then detection reliability is improved, but device complexity and cost increase
Solution Approach 1:
The side mirror assembly serves multiple functions: it provides the traditional mirror reflection function while simultaneously housing the blind spot detection device. This multi-functional integration allows the same structural component to serve both aesthetic/aerodynamic purposes and safety detection purposes.
Solution Approach 2:
The side mirror housing acts as an intermediary structure that houses the detection device, providing both structural support and aerodynamic shielding. This intermediary arrangement allows the detection device to be protected and integrated without requiring separate mounting structures.
