Adjustable Feed Displacer for Autonomous Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned autonomous vehicles lack flexibility in control, particularly in adapting to varying conditions and user preferences, with passive control systems offering limited adaptability.
Innovation Solution
The vehicle's lowest point of the feed displacing means is made adjustable, allowing for greater control flexibility by positioning it outside the centerline, combined with height adjustment and sensor-activated automatic adjustments to ensure optimal operation on uneven terrain and varying feed types, and the inclusion of additional supporting points and sensors for enhanced controllability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lowest point of the feed displacing means is fixed at the center line, then the structure is simple, but the control flexibility is poor
Solution Approach 1:
The patent makes the lowest point of the feed displacing means adjustable rather than fixed, allowing it to be positioned at different locations including outside the center line. This dynamic positioning capability enables the vehicle to adapt to varying feed conditions and control requirements, resolving the contradiction between control flexibility and structural simplicity.
2Reliability
If the lowest point is positioned outside the center line, then the direction of rotation is more predictable, but the device complexity increases
Solution Approach 1:
The patent positions the lowest point of the feed displacing means outside the center line before operation begins. This preliminary asymmetric positioning ensures that when the vehicle encounters feed, the direction of rotation is predetermined and reliable, avoiding unpredictable bidirectional rotation. The adjusting device enables this optimal positioning without requiring complex real-time control mechanisms.
3Adaptability or versatility
If the lowest point is adjustable in height, then the vehicle can adapt to uneven terrain, but the device complexity increases
Solution Approach 1:
The patent incorporates a height adjustment mechanism that allows the lowest point of the feed displacing means to be positioned at different heights relative to the ground. This dynamic height adjustment enables the vehicle to adapt to uneven terrain and varying ground conditions, resolving the contradiction between terrain adaptability and device complexity by providing a relatively simple adjustment mechanism.
4Reliability
If the lowest point is lowered, then the feed displacement is more reliable, but the wear on the displacing means increases
Solution Approach 1:
The patent enables dynamic adjustment of the lowest point's height and position, allowing optimization of the contact between the feed displacing means and the feed material. By adjusting the lowest point outside the center line and at appropriate heights, the system achieves reliable feed displacement while distributing wear more evenly, resolving the contradiction between displacement reliability and wear prevention.
