Motor Vehicle Orientation Compensation via Camera Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in precisely compensating for an inclined position of a motor vehicle, particularly in mobile homes, due to poor visibility of wheels from the driver's seat, makes it challenging to accurately place wheels on compensating wedges, leading to inefficient and potentially unsafe leveling processes.
Innovation Solution
A method utilizing an electronic computing device to determine the oblique orientation of the motor vehicle and the geometry of compensating elements, calculating a compensating section, and providing this information to a control device for precise movement of the vehicle onto the compensating element, ensuring accurate alignment and preventing unintended movement off the element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver manually places the wheel on the compensating wedge, then the leveling process can be performed, but the precision of wheel placement is poor due to limited visibility from the driver's seat
Solution Approach 1:
The patent introduces an intermediary system consisting of cameras mounted on the vehicle and a display device in the driver's seat. These cameras capture images of the wheels and compensating wedges, transmitting them to the driver's seat for clear visualization. This intermediary visual transmission system resolves the visibility problem without requiring the driver to exit the vehicle or physically approach the wheels, thereby improving placement precision while maintaining ease of operation.
Solution Approach 2:
The patent creates visual copies of the actual wheel and compensating wedge positions through camera images displayed on the driver's seat display. Instead of directly observing the physical components, the driver interacts with visual replicas that provide enhanced visibility and clarity. This copying approach allows the driver to accurately assess wheel placement on the compensating wedges from the comfort of the driver's seat, improving both precision and operational ease.
2Measurement precision
If the driver exits the vehicle to check wheel position, then visibility improves, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent employs cameras and a display system as intermediaries to bring the wheel position information directly to the driver's seat. This eliminates the need for the driver to exit the vehicle and physically inspect the wheels, thereby maintaining high visibility of wheel positions while simplifying the overall operation. The driver remains inside the vehicle throughout the leveling process, reducing operational complexity and time requirements.
Solution Approach 2:
The system provides self-service by automatically capturing and displaying wheel position information without requiring the driver to leave the driver's seat. The cameras continuously monitor and transmit visual information, allowing the driver to assess and adjust wheel placement independently and efficiently. This self-service approach reduces operational complexity while maintaining high visibility and precision.
3Manufacturing precision
If the motor vehicle is moved manually onto the compensating wedge, then the leveling process can be performed, but the precision of movement control is insufficient
Solution Approach 1:
The patent implements a feedback system where cameras continuously capture images of the wheels relative to the compensating wedges, and the display device presents this information to the driver in real-time. This visual feedback loop allows the driver to make precise, incremental adjustments to the vehicle position by observing the wheel-wedge relationship. The feedback mechanism enhances movement precision while maintaining ease of operation, as the driver can control the leveling process from the driver's seat with clear visual guidance.
Solution Approach 2:
The patent employs partial action by making small, controlled movements of the motor vehicle onto the compensating wedges rather than attempting to achieve full leveling in one large movement. The driver can observe the wheel position through the camera system and make incremental adjustments, moving the vehicle slightly at a time until the desired precision is achieved. This partial action approach improves movement precision while keeping the operation simple and manageable.
