Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual seed collection from Arabidopsis plants is time-consuming and results in significant seed loss due to inefficiencies in separating fine-sized seeds from plant debris, leading to decreased germination rates.
Innovation Solution
An apparatus comprising a hopper, crushing separator, cyclone part, and strainer filter that physically separates seeds from plant debris through a two-step process, utilizing a motor-driven gear system for crushing and cyclone flow to differentiate seed weight from non-seed plant objects, followed by a strainer filter for spatial separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual seed collection is used, then seed separation can be performed with simple tools, but the process is time-consuming and results in significant seed loss
Solution Approach 1:
The patent replaces the manual mechanical system (hand-rubbing and strainer-filtering) with an automated mechanical system consisting of a crushing separator with rotating gears and a cyclone separator. This substitution dramatically increases seed collection speed while reducing the time required for the separation process.
Solution Approach 2:
The cyclone separator utilizes the natural weight difference between seeds and plant debris to automatically separate them without requiring external intervention. The heavier seeds sink while lighter debris floats, enabling self-service separation that improves productivity without adding operational complexity.
2Productivity
If manual seed collection is used, then simple tools can be employed, but seed loss occurs due to wind and bouncing out of sieve
Solution Approach 1:
The patent replaces the open manual strainer system with a closed automated system comprising a crushing separator and cyclone separator. This closed system prevents seed loss from wind and bouncing by containing the separation process within controlled chambers, thereby improving collection efficiency while minimizing substance loss.
Solution Approach 2:
The cyclone separator acts as an intermediary device between the crushing separator and the collection container. It mediates the separation process by utilizing centrifugal force and weight differentiation to guide seeds into the collection chamber while preventing debris and lost seeds from escaping, thus reducing overall seed loss.
3Productivity
If manual seed collection is used, then no complex equipment is needed, but germination rate decreases due to prolonged collection time
Solution Approach 1:
The patent replaces manual seed collection with an automated mechanical system that rapidly separates seeds from plant material. This substitution reduces the time from plant drying to seed collection, thereby maintaining higher germination rates by minimizing the duration seeds are exposed to potentially harmful environmental conditions.
Solution Approach 2:
The automated system enables continuous operation from plant introduction through crushing, separation, and collection without interruption. This continuous useful action eliminates the delays inherent in manual processing, ensuring seeds are collected quickly while maintaining high germination rates.

Function Achieved in This Case
Enables rapid and convenient separation of fine-sized seeds with a high collection rate, reducing seed loss and maintaining germination rates by automating the seed separation process.
Implementation Method 1
a cyclone part that the seeds and non-seed plant objects, which are crushed and separated in the crushing separator, are introduced, and by cyclone flow, the heavy seeds sink whereas the light-weighted non-seed plant objects float inside, thereby separating the seeds from the rest of plant debris
Implementation Method 2
a strainer filter part that is mounted to a lower end of the cyclone part and passes the seeds through a strainer filter, thereby spatially separating the seeds from the rest of plant debris
