Vine Shoot Composite Trellising Stakes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The systematic burning of vine shoots after pruning generates significant CO2 emissions and ecological waste, and existing agricultural accessories made from wood or metal are prone to rot and rust, leading to high replacement costs.
Innovation Solution
A composite material is developed using a plastic matrix incorporating vine shoot powder, which is produced by grinding, drying, and sieving vine shoots, and mixed with polypropylene or polylactic acid to create a lightweight, rot-proof agricultural accessory such as trellising stakes, reducing material costs and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vine shoots are burned after pruning, then waste disposal is simple, but CO2 emissions increase and ecological waste is generated
Solution Approach 1:
The patent converts the harmful waste (vine shoots that would be burned) into a beneficial raw material by grinding them into powder and incorporating them into composite materials for agricultural accessories, thereby eliminating CO2 emissions from burning while creating valuable products
Solution Approach 2:
Instead of discarding vine shoots through burning, the patent recovers them by collecting, grinding, and integrating the shoot powder into composite materials, transforming waste into a useful resource for manufacturing durable agricultural products
2Ease of manufacture
If traditional wood or metal accessories are used for trellising, then initial manufacturing cost is lower, but they rot or rust quickly requiring frequent replacement
Solution Approach 1:
The patent creates a composite material combining plastic matrix with vine shoot powder, achieving both cost-effectiveness and enhanced durability. The composite resists rot and rust while maintaining low manufacturing costs, eliminating the need for frequent replacements of traditional wood or metal accessories
Solution Approach 2:
The patent changes the material parameters by incorporating vine shoot powder (at least 20% by weight) into the plastic matrix, modifying the physical and chemical properties to achieve rot-proof characteristics while maintaining structural integrity and longevity
3Quantity of substance
If high proportion of vine shoot powder is used in composite material, then petroleum matrix cost is reduced, but material strength may be compromised
Solution Approach 1:
The patent optimizes the proportion of vine shoot powder to at least 20% by weight relative to the composite material, significantly reducing petroleum matrix usage while maintaining adequate strength through proper formulation and processing
Solution Approach 2:
The composite material formulation combines plastic matrix with vine shoot powder in optimized proportions, creating a synergistic material that balances cost reduction with structural strength requirements for agricultural accessories
