Solution Overview
Problem
The market value and practicality of recycled products from out-of-season or discarded textiles are affected by their manufacturing methods, limiting their successful reuse and resource utilization.
Innovation Solution
A recycled board is manufactured using recycled fabrics, with fiber pieces of less than or equal to 10 mm diameter, mixed with an adhesive cured by temperature, pressure, or light, and molded through processes like crushing, dry stirring, mixing, rolling, and hot pressing, with adhesive content ranging from 20-50 wt %.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If recycled fabrics are used to manufacture boards, then resource recycling efficiency is improved and waste is reduced, but the market value and practicality are affected by manufacturing methods
Solution Approach 1:
The recycled fabrics are crushed into small fiber pieces with an average diameter of less than or equal to 10 mm, segmenting the material into uniform units that can be easily processed and combined with adhesive in a controlled manufacturing process
Solution Approach 2:
The invention creates a composite material by combining crushed fiber pieces (50-80 wt %) with adhesive (20-50 wt %) to form a recycled board that maintains structural integrity and practical applications while utilizing recycled materials
2Shape
If fiber pieces with smaller diameter are used, then the appearance becomes richer and market value increases, but the manufacturing process complexity increases
Solution Approach 1:
The invention specifies a parameter range for fiber piece diameter (average diameter ≤ 10 mm) that optimizes both appearance quality and manufacturability, balancing aesthetic requirements with processing feasibility
Solution Approach 2:
The crushing process is performed in advance to pre-process the recycled fabrics into uniformly sized fiber pieces before mixing with adhesive, simplifying subsequent manufacturing steps while ensuring consistent appearance quality
3Strength
If adhesive content is increased to improve board strength, then the mechanical properties improve, but the resource recycling efficiency decreases
Solution Approach 1:
The invention defines an optimal range for adhesive content (20-50 wt %) that provides sufficient structural strength while maximizing the proportion of recycled fiber material (50-80 wt %) in the final product, balancing mechanical performance with recycling efficiency
