Rotatable Two-Point Hitch System for Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural vehicles face challenges in efficiently coupling and uncoupling towed implements due to limited vertical travel of three-point hitches, which can result in improper height adjustments for operational and transport positions, leading to issues like dragging or insufficient clearance over obstacles.
Innovation Solution
A rotatable two-point hitch system with adjustable rotatable ends that can rotate 0 to 360 degrees, allowing for customizable attachment heights and positions, facilitated by hydraulic, pneumatic, or electric systems, and a control system for precise angle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-point hitch system is used for coupling implements, then the attachment mechanism is structurally simple, but the vertical travel is limited resulting in improper height adjustments
Solution Approach 1:
The patent applies the dynamics principle by making the hitch arms rotatable rather than fixed. The rotatable ends can rotate 0 to 360 degrees, allowing the attachment points to dynamically adjust their position vertically and angularly. This dynamic capability enables proper height adjustment for both operational and transport positions while maintaining structural simplicity through the rotatable joint mechanism.
2Adaptability or versatility
If fixed attachment points are used, then the hitch system structure is simple, but the ability to accommodate varying tire sizes and terrains is reduced
Solution Approach 1:
The rotatable ends provide dynamic adaptability by allowing the attachment points to rotate and reposition themselves according to varying tire sizes, terrain conditions, and implement requirements. This rotational freedom enables the system to accommodate different operational scenarios without requiring a complex adjustable mechanism.
3Measurement precision
If manual attachment adjustment is used, then the control system is simple, but the precision of angle control and positioning is reduced
Solution Approach 1:
The patent incorporates a control system with sensors that provide feedback on the rotational position of the hitch arms. This feedback mechanism enables precise angle control and positioning by continuously monitoring the actual position and making necessary adjustments. The control system can be operated manually or automatically, providing precise positioning capability while maintaining reasonable system complexity.
