Solution Overview

Problem

The fashion and textile industry faces challenges in resource circularity due to a lack of effective upstream waste clothing collection and recycling systems, leading to minimal recycling of single-material and simple blend fashion products, which are often reused rather than recycled, and there is a need for a system that separates and collects waste clothing by material type for high-value recycling.

Innovation Solution

A waste clothing collector equipped with an identification unit to recognize material information, an inlet to separate based on pre-input conditions, a weight measurement unit, and collection bins for physical or chemical recycling, along with a cash-back amount calculation unit to compensate users, ensuring efficient separation and recycling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If waste clothing is collected through traditional mixed collection methods, then collection simplicity is maintained, but recycling value is lost due to inability to separate materials

Engineering Contradiction:
Improverecycling valueVSAvoidcollection system complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The collection system is segmented into multiple dedicated collection bins, each designed for specific material types (e.g., cotton bin, polyester bin, wool bin). This segmentation enables automatic material separation at the collection point, preserving recycling value while maintaining operational simplicity for users who merely deposit clothing without manual sorting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An identification unit acts as an intermediary between the user and the collection bins. This mediator automatically detects material composition through RFID tags, barcodes, or image recognition, then directs clothing to the appropriate bin, eliminating the need for users to manually sort while maximizing recycling value.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If manual sorting of waste clothing by material type is implemented, then recycling effectiveness is improved, but labor intensity and operation complexity increase

Engineering Contradiction:
Improverecycling effectivenessVSAvoidcollection operation ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The collection system performs self-service through automated identification and routing mechanisms. The identification unit autonomously determines material composition and directs clothing to appropriate bins without human intervention, achieving high recycling effectiveness while maintaining ease of operation for users.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical sorting operations are replaced with automated identification systems (RFID readers, barcode scanners, or image recognition cameras) that electronically detect material composition and trigger automated routing mechanisms, eliminating labor-intensive manual sorting while improving recycling effectiveness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If dedicated collection bins for each material type are provided, then material separation quality is improved, but device complexity and space requirements increase

Engineering Contradiction:
Improvematerial separation qualityVSAvoidcollector space
Core Design Contradiction:
Manufacturing precisionVSVolume of stationary object

Solution Approach 1:

The collection system employs universal collection bins that can accommodate multiple material types through flexible compartmentalization or movable dividers. A single multi-functional bin structure replaces multiple dedicated bins, achieving high material separation quality while minimizing space requirements through adaptive configuration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The collection bins are designed with nested or stacked configurations where smaller specialized bins are placed within or upon larger general bins. This nesting arrangement enables efficient use of vertical space while maintaining dedicated separation for different material types, achieving high separation quality without proportionally increasing overall volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If user compensation systems are implemented, then user participation is improved, but system complexity increases

Engineering Contradiction:
Improveuser participationVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements immediate feedback mechanisms that provide users with real-time information about their contribution to recycling, including material identification results, weight measurements, and calculated compensation amounts. This transparent feedback loop enhances user participation by demonstrating the impact of their actions while the automated calculation process minimizes added complexity.

Inventive Principle:
Principle #23Feedback
