Alfalfa Pollination Machine with Recirculating Air Manifold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanical pollinators fail to effectively trip alfalfa blossoms and deposit foreign pollen on the stigma, leading to self-pollination and reduced seed production, as they cannot replicate the intricate pollination process of Alfalfa Leafcutter Bees on a large scale.
Innovation Solution
A cross-pollination machine with enclosed chambers and a vacuum and blow-back system, utilizing sealing rollers and air ducts to trip blossoms and recirculate pollen from one plant to another, ensuring foreign pollen is deposited on the stigma before self-pollen inundates it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Alfalfa Leafcutter Bees are applied in extremely large numbers for pollination, then pollination effectiveness is improved, but cost and financial risk increase significantly
Solution Approach 1:
The patent creates a mechanical copy of the bee pollination process using a machine that physically trips the keel pedals and deposits pollen, replacing the need for actual bees while replicating their pollination function. This resolves the contradiction by providing reliable pollination through mechanical means rather than relying on large numbers of expensive bees.
Solution Approach 2:
The invention substitutes a mechanical pollination system for the biological bee system. The machine uses mechanical components (rollers, tripping mechanisms, pollen dispensers) to perform pollination tasks that were previously done by bees, thereby eliminating the high cost and risk associated with maintaining large bee populations.
2Productivity
If mechanical pollinators are used to replace bees, then cost is reduced, but pollination effectiveness deteriorates because they cannot trip blossoms and deposit foreign pollen
Solution Approach 1:
The patent divides the pollination function into separate mechanical components: a tripping mechanism that collapses the keel pedals, a pollen collection system that gathers foreign pollen, and a deposition system that places pollen on the stigma. This segmentation allows each component to be optimized for its specific function, ensuring both cost efficiency and pollination effectiveness.
Solution Approach 2:
The machine performs preliminary actions by first tripping the blossom to expose the stigma and pollen, then collecting foreign pollen from other plants before depositing it on the stigma. This sequence ensures that foreign pollen is deposited before self-pollen can clog the stigma, maintaining pollination effectiveness while using a cost-effective mechanical system.
3Device complexity
If blossoms are tripped without foreign pollen deposition, then mechanical operation is simplified, but self-pollination occurs and seed production is reduced
Solution Approach 1:
The patent introduces an intermediary pollen deposition step between tripping and fertilization. The machine acts as an intermediary by collecting foreign pollen from donor plants and delivering it to the stigma, preventing self-pollination while maintaining simple mechanical operation. This intermediary function ensures seed production without complicating the overall mechanical process.

Function Achieved in This Case
The machine successfully trips each blossom and ensures cross-pollination by circulating foreign pollen, increasing alfalfa seed production on a large scale without relying on bees, while maintaining a sealed environment to prevent self-pollination.

AI summary
A pollination machine (10) with improved cross-pollination abilities may feature a plurality of pollen recirculation chambers with an air circulation manifold (130A, 131A, 133A, etc.) connecting them in a manner that air in one chamber (30A), together with associated pollen, is removed from the one chamber and redirected to a second (30B), and so on until air is returned to the first (30A). The chambers' initial roller entrances (118) will serve to trip blossoms and release both pistol and pollen but a current in the air circulation manifold contains and will deposit foreign pollen grains on the plants' stigmas before they are inundated by the blossoms' own pollen. The air current also collects the plants' pollen and carries it to other chambers so that other plants will be cross-pollinated.
