Solution Overview

Problem

Current methods for recycling textile and leather scraps are complex and often require processing into fibers, making them difficult to reutilize effectively, especially for materials like tanned leather scraps which are typically discarded due to their processing history.

Innovation Solution

A sheet composed of a polymer matrix with embedded textile particles, where textile scraps are used as particles rather than fibers, allowing for simplified processing and inclusion of tanned leather scraps without compromising quality, using a process involving shredding, agglomeration, and extrusion to create a thermoplastic deformable material suitable for various applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If textile scraps are processed into fibers through complicated operations, then the material quality is improved, but the processing complexity increases

Engineering Contradiction:
Improvematerial qualityVSAvoidprocessing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

Instead of processing textile scraps into fibers through complicated operations, the invention inverts the approach by directly using the scraps as particles embedded in a polymer matrix. This eliminates the need for complex fiber processing while maintaining material quality through the composite structure.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention creates a composite material where textile particles are embedded in a polymer matrix. This composite approach allows the use of raw textile scraps without extensive processing, as the polymer matrix provides structural integrity and the textile particles contribute to the overall material properties.

Inventive Principle:
Principle #40Composite materials

2Productivity

If tanned leather scraps are used directly, then the recycling efficiency is improved, but the material compatibility deteriorates

Engineering Contradiction:
Improverecycling efficiencyVSAvoidmaterial compatibility
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The invention changes the physical state and size parameters of the textile scraps by converting them into particles through shredding or grinding. This parameter change allows tanned leather scraps to be directly incorporated into the polymer matrix without compromising compatibility, as the particle form facilitates uniform distribution and bonding.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The polymer matrix acts as an intermediary that accommodates the textile particles, including tanned leather scraps. The matrix provides a compatible medium that binds the particles together, resolving potential compatibility issues between different textile materials and enabling direct use of processed scraps.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If textile scraps are shredded and ground into particles, then the processing time is reduced, but the energy consumption increases

Engineering Contradiction:
Improveprocessing timeVSAvoidenergy consumption
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The invention applies partial processing to the textile scraps by shredding them into particles rather than completely processing them into fibers. This partial action reduces processing time compared to full fiberization while the energy consumption is managed by optimizing the shredding and grinding parameters to achieve sufficient particle size for composite incorporation.

Inventive Principle:
Principle #16Partial or excessive action
