Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If seeds are subjected to conventional moistening and aeration treatment, then germination can be induced, but the treatment homogeneity across the seed mass is insufficient
Solution Approach 1:
The patent replaces conventional mechanical spray nozzles with an ultrasonic nebulizer that generates a mist of water particles smaller than 100 micrometers. This substitution of the mechanical spraying system with an ultrasonic-based system enables much finer and more uniform water distribution across the seed mass, directly resolving the homogeneity issue while maintaining effective germination induction.
Solution Approach 2:
The patent changes the physical parameter of water particle size by using ultrasonic vibration to generate mist particles smaller than 100 micrometers, and further separates particles larger than 100 micrometers using a filter. This parameter change in particle size distribution ensures more uniform penetration and distribution of water throughout the seed mass, achieving homogeneous germination treatment.
2Productivity
If water is applied to moisten seeds during germination, then seeds can germinate, but water overflow and waste occur
Solution Approach 1:
By replacing conventional spray nozzles with an ultrasonic nebulizer, the system achieves much more efficient water utilization. The ultrasonic-generated mist particles smaller than 100 micrometers are distributed so uniformly that minimal water is needed to achieve complete coverage, eliminating the water overflow and waste problems associated with conventional mechanical spraying systems.
Solution Approach 2:
The patent changes the water application parameter from large spray droplets to fine mist particles smaller than 100 micrometers generated by ultrasonic vibration. This parameter change enables complete and uniform coverage of the seed mass with minimal water quantity, preventing both water overflow and under-moistening, thus eliminating waste while maintaining high germination yield.

AI summary
The present invention relates to a seed germination device comprising a tank (2) for receiving water to wet the seeds, and at least one housing (4) for receiving seeds. Said device is characterized in that it also includes: a nebulizer (111) for generating a water particle mist from the water contained in the tank; and a filter (3), between the nebulizer (111) and the housing (4), for retaining the water particles, the particle sizes of which are larger than 100 micrometers (preferably larger than 5 micrometers and more preferably larger than 100 nanometers). The filter (3) comprises at least one pipe (31) connected to the housing (4) such as to enable the mist particles having sizes smaller than 100 micrometers to delivered to the housing (4).
