Elastomeric Fencing Accessories Resolving Temperature Brittleness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fencing accessories made from polypropylene become brittle at lower temperatures, particularly in frosty weather, leading to reduced durability and functionality during storage, transportation, and use.
Innovation Solution
Development of fencing accessories with elastomeric properties using a combination of thermoplasts, thermosets, and elastomers such as polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), and polyvinyl butyral (PVB), along with fillers like chalk, which provide improved flexibility and resistance to temperature-related brittleness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polypropylene is used for fencing accessories, then manufacturing cost and ease of processing are improved, but flexibility and resistance to temperature-related brittleness deteriorate
Solution Approach 1:
The patent applies composite materials by combining polypropylene with elastomeric additives (such as polyethylene-co-acrylic acid copolymer, polyvinylidene fluoride-co-hexafluoropropylene, or thermoplastic elastomers) to create a multi-component polymer composition. This composite structure maintains the ease of processing benefits of polypropylene while incorporating the flexibility and low-temperature resilience of elastomeric materials, thereby resolving the contradiction between manufacturing ease and temperature-related durability.
Solution Approach 2:
The patent modifies the physical and chemical parameters of polypropylene by incorporating elastomeric additives at specific weight percentages (5-50 wt% of total polymer composition). This parameter change transforms the brittle characteristics of pure polypropylene at low temperatures while preserving its processing advantages, achieving both ease of manufacture and improved temperature resistance through controlled compositional adjustment.
2Quantity of substance
If polypropylene is used for fencing accessories, then cost is reduced, but flexibility and durability in cold weather deteriorate
Solution Approach 1:
The patent creates a cost-effective composite material system where polypropylene is combined with elastomeric additives in optimized ratios. This composite approach maintains the economical advantages of polypropylene while significantly improving flexibility and cold-weather durability through the elastomeric component, achieving both cost efficiency and enhanced operational performance.
Solution Approach 2:
The patent adjusts the compositional parameters by incorporating elastomeric additives at controlled concentrations (5-50 wt%), which modifies the material's mechanical properties to include improved flexibility and cold-temperature resilience while preserving the cost-effectiveness of the base polypropylene material.
3Device complexity
If traditional polypropylene accessories are used, then simplicity of material composition is maintained, but resistance to chemical corrosion and durability deteriorate
Solution Approach 1:
The patent develops a composite material system that combines polypropylene with elastomeric additives known for their chemical resistance properties. This composite structure enhances resistance to chemical corrosion and improves overall durability while maintaining relatively simple material composition and processing requirements, thereby resolving the contradiction between compositional simplicity and corrosion resistance.
