Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pollen activation solutions cause pollen grains to expand and become damaged or burst due to osmotic pressure, leading to rapid inactivation within 30 minutes.
Innovation Solution
A pollen activation solution containing an aqueous solution with substances that activate germination and pollen tube elongation, combined with powdered charcoal that has not been subjected to activation treatment, is used to extend the period from dispersion to inactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pollen is dispersed in an aqueous pollination agent, then pollen germination is activated, but the osmotic pressure of water causes pollen grains to expand and become damaged or burst, resulting in rapid inactivation within 30 minutes
Solution Approach 1:
The patent introduces a film-forming substance as an intermediary between the aqueous pollination agent and the pollen grains. This substance forms a protective film on the pollen grain surface, mediating the interaction between water and pollen to prevent osmotic damage while allowing germination activation. The film acts as a barrier that controls water penetration, preventing the harmful expansion and bursting caused by direct aqueous contact.
Solution Approach 2:
The patent changes the physical-chemical parameters of the pollination system by incorporating a film-forming substance that alters the surface properties of pollen grains. This modification changes the permeability and osmotic characteristics of the pollen surface, enabling the system to maintain pollen integrity in aqueous environments while still permitting necessary germination processes.
2Duration of action of moving object
If a film-forming substance is added to the pollen activation solution, then pollen activity duration is extended, but the solution composition becomes more complex
Solution Approach 1:
The film-forming substance serves multiple functions simultaneously: it forms a protective film on pollen grains, extends pollen activity duration, and maintains compatibility with the aqueous pollination agent. This multi-functionality reduces the need for multiple separate additives, thereby limiting the increase in solution composition complexity while achieving the desired extension of pollen activity.
3Reliability
If the concentration of aqueous solution is increased to enhance pollen activation, then germination rate improves, but osmotic pressure increases causing faster pollen damage
Solution Approach 1:
The film-forming substance acts as a protective intermediary that allows the system to utilize higher concentrations of aqueous solution for enhanced germination activation without suffering from increased osmotic damage. The film barrier enables the pollen to withstand higher osmotic pressures while still benefiting from the improved germination rates associated with concentrated solutions.
