Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cross-pollination in agriculture require manual detasseling and rely on natural wind for pollen distribution, which can be inefficient and result in uneven pollination, leading to reduced crop yields and increased labor costs.
Innovation Solution
A device comprising a carriage-mounted pollination system with pollen-releasing apparatuses and air nozzles that travel along rows of crop plants, blowing air to disperse pollen from pollen-bearing plants to pollen-receiving plants, ensuring consistent and efficient pollination across the field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual detasseling and natural wind pollination are used, then labor costs and time consumption increase, but the pollination uniformity and crop yield improve
Solution Approach 1:
The patent replaces manual mechanical detasseling and natural wind pollination with a mechanical pollination device that uses controlled air flow to deliver pollen. The device includes a carriage-mounted system with pollen-releasing apparatuses and air nozzles that mechanically transport pollen from pollen-bearing plants to pollen-receiving plants, eliminating the need for manual labor and unpredictable natural wind conditions.
Solution Approach 2:
The patent employs pneumatic principles by using air nozzles to generate controlled air flows that carry pollen from the pollen-releasing apparatuses to the target plants. The air flow is directed through nozzles positioned adjacent to the pollen-releasing apparatuses, creating a pneumatic transport system that efficiently delivers pollen across the field rows.
2Manufacturing precision
If natural wind is relied upon for pollen distribution, then equipment complexity is reduced, but pollination uniformity and crop yield decrease
Solution Approach 1:
The pollination device is divided into multiple pollination units, each comprising a pollen-releasing apparatus and associated air nozzles. These units are distributed along the carriage to cover multiple rows simultaneously, with each unit independently delivering pollen to specific target areas, ensuring uniform pollination across the entire field.
Solution Approach 2:
The device allows for adjustment of air flow parameters through the nozzles to optimize pollen delivery. The air flow rate, direction, and velocity can be controlled to match different pollination requirements, plant heights, and environmental conditions, enabling precise control over pollination uniformity while adapting to various field conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly increases crop yields by ensuring uniform pollination, reducing labor and time required for manual pollination, and improving the percentage of cross-pollinated plants, as demonstrated in various field trials.
Implementation Method 1
At least one nozzle adjacent the pollen-releasing apparatus is configured for discharging air along a flow path such that the discharged air delivers at least some of the released pollen to the pollen-receiving rows of crop plants.

AI summary
A pollinating device for pollinating crop plants includes a base mountable on a carriage. At least one pollination unit is mounted on the base and includes a pollen-releasing apparatus configured to release pollen from male flowers of the plants and at least one nozzle for directing fluid along a flow path for delivering at least some of the released pollen to the pollen-receiving rows of crop plants. Certain pollinating devices include multiple pollination units spaced apart along a width of the base. Some pollination units include at least two opposing nozzles. Plants are pollinated by driving the carriage along a field and directing air from the nozzles over the pollen born by some plants to deliver the pollen to female flowers of other plants in the field.
