Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biodegradable plastics face challenges such as high production costs, incomplete degradation in landfills, and shape loss when exposed to liquids, while photodegradable plastics are ineffective in landfills without sunlight, and alternative materials like rice or starch-based substitutes lack durability and shape retention.
Innovation Solution
A curable composition comprising 20-30 wt% boiled meat slices, 1-15 wt% konjac, 30-50 wt% glue, and 5-15 wt% kelp, which can be processed through injection or extrusion molding to create structures with improved mechanical properties and rapid degradation, maintaining shape even in liquid environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If biodegradable plastics are used, then environmental friendliness is improved, but production cost increases
Solution Approach 1:
The patent uses a composite material system combining multiple natural polymers (starch, cellulose, chitosan) with plasticizers and crosslinking agents to create a biodegradable plastic alternative that maintains acceptable mechanical properties while reducing production costs compared to single-component biodegradable plastics
Solution Approach 2:
The patent adjusts formulation parameters including the ratios of starch to cellulose to chitosan, plasticizer content, and crosslinking degree to optimize both biodegradability and production cost, allowing flexible adjustment based on application requirements
2Duration of action of stationary object
If biodegradable plastics are used, then degradation capability is improved, but shape retention in liquid deteriorates
Solution Approach 1:
The patent applies crosslinking treatment to the polymer network before the material contacts liquid environments, creating a pre-stabilized structure that resists shape loss while maintaining subsequent biodegradability through controlled hydrolysis of crosslink bonds
Solution Approach 2:
The patent creates different functional zones within the material structure, with crosslinked regions providing shape stability in liquid and uncrosslinked or hydrolyzable regions enabling degradation, achieving spatial differentiation of properties
3Duration of action of stationary object
If photodegradable plastics are used, then degradation capability is improved, but effectiveness in landfill deteriorates
Solution Approach 1:
The patent replaces photodegradation mechanisms with biochemical degradation mechanisms that function independently of light exposure, using microbially degradable polymer compositions that can decompose in dark landfill environments through enzymatic and microbial action
Solution Approach 2:
The patent changes the degradation trigger parameter from light exposure to moisture and microbial presence, making the material adaptable to various environments including landfills, composting facilities, and natural ecosystems where these conditions exist
