Adjustable Nutrient Knife Lateral Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural implements often waste nutrients by dispensing them in the middle zone between crop rows, leading to increased costs for growers as plants cannot absorb these nutrients effectively, prompting the need for a system that can adjust the lateral position of nutrient application to target the plant stems more efficiently.
Innovation Solution
A ground-engaging implement with a front member and rear members connected by pivotable arms, featuring actuators and position sensors that allow for precise lateral adjustment of nutrient knives relative to the front member, enabling targeted application closer to plant rows, reducing nutrient waste and increasing yield per land unit area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If nutrients are dispensed in the middle zone between crop rows, then the implement structure is simple and easy to operate, but nutrient absorption efficiency decreases and growers' costs increase
Solution Approach 1:
The patent applies the dynamics principle by making the implement structure movable and adjustable. The rear member can laterally shift relative to the front member through pivotable arms and actuators, allowing the nutrient application position to dynamically adapt from the middle zone to closer to plant rows, thereby resolving the contradiction between operational simplicity and nutrient efficiency
Solution Approach 2:
The patent changes the lateral position parameter of the nutrient application point. By adjusting the lateral offset between the front and rear members, the system can vary the nutrient dispensing location from the traditional middle zone to positions closer to the plant rows, optimizing nutrient absorption while maintaining reasonable operational complexity
2Reliability
If greater dosages or concentrations of nutrients are applied to compensate for middle zone placement, then desired nutrient absorption results are achieved, but growers' costs increase
Solution Approach 1:
The patent applies preliminary action by positioning the nutrient application point optimally before the planting season begins. The adjustable implement allows growers to pre-configure the lateral position to target the zone closest to plant rows, ensuring maximum nutrient absorption efficiency from the start and reducing the total nutrient quantity needed throughout the season
3Productivity
If the lateral position of nutrient application is adjusted closer to plant rows, then nutrient absorption efficiency increases and yields improve, but the implement structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the implement into distinct functional modules: a front member for guidance, a rear member for nutrient application, and pivotable arms connecting them. This modular segmentation allows the lateral adjustment mechanism to be added as a separate functional unit rather than redesigning the entire implement, thereby achieving improved productivity with controlled increases in complexity

AI summary
A first rear member is spaced apart from the front member and positioned generally parallel to the front member. A first pair of first pivotable arms are generally parallel to each other. The first pair of first pivotable arms are rotatably connected to the front member at two front pivot points. The first pair of first pivotable arms are rotatably connected to the rear member at two rear pivot points. At least one first opener (e.g., nutrient knife or projecting, ground-engaging member) extends downward from or with respect to the first rear member.
