Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems face challenges in achieving precision farming due to high production costs and resource wastage, particularly with large-scale equipment that cannot efficiently use seeds and agrochemicals, and cause soil damage, while autonomous agricultural machines lack sufficient drive power for furrow opening in conventional planting methods.
Innovation Solution
A self-propelled seeding vehicle equipped with a control system, seed tank, metering system, and seed placement unit that allows for independent seed deposition at specific locations, enabling precise planting without mechanical linkage to ground traversal, using a cam-controlled punch seeding mechanism for efficient seed placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional drill seeding method is used with large-scale equipment, then planting operation can be performed, but seed wastage increases and precision farming cannot be achieved
Solution Approach 1:
The patent replaces the conventional mechanical drill seeding system with a punch seeding mechanism that uses a punching tool to create holes and deposit seeds individually. This substitution enables precise seed placement at predetermined locations without the need for furrow opening, thereby reducing seed wastage while maintaining planting efficiency through automated control
Solution Approach 2:
The invention changes the seeding method from continuous furrow-based drilling to discrete punch-based deposition. By altering the fundamental parameter of seed placement mechanism (from mechanical drilling to punch insertion), the system achieves both precision farming (reducing seed wastage) and maintains productivity through automated vehicle traversal
2Power
If conventional drill seeding with furrow opening is used, then seeds can be planted, but drive power requirements exceed available power in autonomous vehicles
Solution Approach 1:
The patent extracts and removes the furrow opening operation from the seeding process. By eliminating the plowing or disc-based furrow creation step, the system dramatically reduces the power requirements while maintaining the essential seeding capability through direct punch-based seed deposition into the soil
Solution Approach 2:
The high-power mechanical furrow opening system is replaced with a low-power punch insertion mechanism. This substitution enables autonomous vehicles with limited power resources to perform seeding operations effectively
3Manufacturing precision
If punch seeding is used without mechanical linkage to ground traversal, then precise seed placement is achieved, but control complexity increases
Solution Approach 1:
The patent replaces mechanical linkage between the punch seeding mechanism and ground traversal wheels with an electronic control system. This substitution uses sensors, processors, and actuators to independently control punch activation timing, achieving precise seed placement at predetermined locations while managing control complexity through automated feedback loops

AI summary
A self-propelled seeding vehicle includes a seed sorting and placement unit controlled by an on-board control system. The control system further controls a motive power unit operable to cause the vehicle to controllably traverse an area of ground to be seeded. The control system is further operable to control the sequential depositing of seeds independently of the speed of traversal of the ground by the vehicle.
