Asteraceae Root Cutting for Reusable Latex Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for extracting latex from Taraxacum kok-saghyz plants of the Asteraceae family do not allow for repeated latex extraction from the same plant individuals, as the plants cannot be reused after initial latex extraction.
Innovation Solution
A method involving cutting the roots to leave a portion on the plant, followed by transpiration-suppressed cultivation, allows for repeated latex extraction by focusing on the root-tip portions and reducing water absorption, enabling the plant to be reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If roots are completely removed during latex extraction, then latex extraction efficiency is improved, but plant reuse becomes impossible
Solution Approach 1:
The root system is segmented into two functional zones: the tip portion (5-10 cm) is removed for latex extraction while the base portion remains in the plant for water absorption and regeneration. This segmentation allows simultaneous optimization of latex yield and plant reusability without requiring complete root removal or lengthy regrowth periods.
2Loss of energy
If all leaves are removed to suppress transpiration, then water loss is reduced, but photosynthesis capacity decreases
Solution Approach 1:
Leaf removal is applied selectively rather than uniformly: leaves in the lower portion of the plant are removed to suppress transpiration from areas with limited water access, while upper leaves are retained to maintain photosynthesis capacity. This localized approach optimizes the balance between water conservation and energy production.
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
This method increases latex extraction efficiency and reduces the time required for latex extraction, allowing multiple extractions from a single plant, thereby enhancing the utilization of plant resources for producing environment-friendly rubber products like pneumatic tires.
Implementation Method 1
the water absorption of the plant can be reduced because the roots have been cut in the extraction of latex... a treatment of suppressing transpiration
