Vehicle Soil Sampling Head with Independent Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil detection devices in vehicles are limited by the maximum travel of the detection head, restricting the vehicle's ground clearance even in the rest position, which can impede movement.
Innovation Solution
A height adjustment device is introduced between the alignment device and the detection head, allowing independent adjustment of the detection head's position, enabling increased ground clearance by allowing the detection head to be lowered and raised separately from the alignment device, and optionally operated manually or motorized with a linear drive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the detection head is integrated with the alignment device as a single unit, then the device structure is simple, but the ground clearance is restricted due to limited travel range
Solution Approach 1:
The detection device is segmented into two independent functional units: the alignment device for horizontal positioning and the height adjustment device for vertical positioning. This segmentation allows the detection head to achieve greater vertical travel range (improving ground clearance) while maintaining structural simplicity through modular design.
2Length of moving object
If the detection head travel range is increased to improve ground clearance, then the vehicle mobility is improved, but the device complexity increases
Solution Approach 1:
The height adjustment device is designed to be manually operable, allowing the same mechanism to serve multiple functions: adjusting detection head height for ground clearance optimization and positioning the detection head at various heights for different detection scenarios. This multi-functionality increases travel range without proportionally increasing device complexity.
3Ease of operation
If the alignment device is used to lower the detection head, then the detection position is achieved, but the maximum travel is limited restricting ground clearance
Solution Approach 1:
The positioning function is segmented between the alignment device (horizontal positioning) and the height adjustment device (vertical positioning). This separation allows each device to be optimized for its specific function, with the height adjustment device providing extended vertical travel range to improve ground clearance while the alignment device maintains ease of operation for horizontal positioning.

AI summary
The device has a sensing head that can be brought into contact with a ground by actuation of an alignment device (10) in a sensing region above the ground. A height-adjusting device (20) is provided between the alignment device and the sensing head for adjusting the height of the sensing head above the ground. The height adjustment device is operable manually or by a motor, independent of the operation of the alignment device, where the height adjustment device includes a linear drive and a threaded spindle. An independent claim is also included for a method for sensing the ground from the interior of a vehicle.
