Vehicle Sensor Mounting with Rotary Closure for Secure Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasonic sensors on vehicles can become misaligned or detached due to design conflicts with braking systems, leading to safety issues such as erroneous braking signals from low-speed bumps, requiring a secure mounting solution that balances tight fit and adjustment angle requirements.
Innovation Solution
A mounting device with a securing mechanism that forms a rotary closure using a fastening element and receptacle, allowing for low-force attachment and positive axial securing of sensors, such as ultrasonic, camera, radar, or LIDAR sensors, on vehicle components like bumpers or fenders, using a bayonet-type or snap connection to prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultrasonic sensors are mounted with a tight fit to prevent detachment, then sensor security is improved, but the adjustment angle is restricted
Solution Approach 1:
The mounting device incorporates a rotary closure mechanism that allows the sensor to be mounted in different angular positions (0°, 45°, 90°, 135°) while maintaining secure attachment. This dynamic adjustment capability resolves the contradiction by enabling both tight fit and angle variability through rotatable positioning features.
2Reliability
If traditional fastening methods are used to secure sensors, then sensor attachment is reliable, but high operational forces are required
Solution Approach 1:
The patent replaces traditional screw or clip fastening mechanisms with a rotary closure system that uses rotational motion to engage and secure the sensor. This substitution reduces the linear force required during installation while maintaining reliable attachment through the rotational locking mechanism.
Solution Approach 2:
The mounting device changes the mounting parameter from linear insertion force to rotational torque. By converting the fastening action from pushing or pulling to rotating, the system achieves secure attachment with lower operational forces applied in the installation direction.
3Adaptability or versatility
If sensors are allowed to move freely for adjustment, then alignment flexibility is improved, but sensor detachment risk increases
Solution Approach 1:
The mounting device provides preliminary adjustment options at specific angular positions (0°, 45°, 90°, 135°) before final securing. This allows the sensor to be aligned flexibly during installation and then locked into place, preventing detachment while maintaining alignment flexibility during the mounting process.
