Solution Overview

Problem

Current recycling methods for chip card waste result in significant material losses and inefficient recycling due to the mixture of plastics and metals, where metals contaminate plastic recycling processes and plastics are not recycled as they are incinerated, violating recycling regulations.

Innovation Solution

A machine with a cutting module, separate collectors, and a grinder that cuts and separates chip card materials into metallic, plastic, and polluting elements, ensuring effective destruction and recycling by directing each material type to specialized channels, preserving the intrinsic qualities of plastics and maintaining security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If shredded cards are processed in large volumes by type of plastic in a common flow with other waste, then plastic recycling volume is increased, but metals and impurities contaminate the plastic recycling process requiring frequent filter changes

Engineering Contradiction:
Improveplastic recycling volumeVSAvoidmetal contamination
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The invention divides the recycling stream into separate channels for different materials. A sorting system with multiple collectors separates plastic, metal, and polluting elements into distinct flows, preventing metal contamination of the plastic recycling stream while maintaining high processing volumes.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If shredded material is sent to precious metal recycling channels, then metal recovery is achieved, but plastics are incinerated instead of recycled violating recycling regulations

Engineering Contradiction:
Improvemetal recoveryVSAvoidplastic recycling loss
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The system separates plastic and metal into different collection streams. Plastic elements are directed to plastic recycling channels while metal elements go to precious metal recycling channels, allowing both materials to be recycled through their respective specialized channels without contamination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sorting system acts as an intermediary between the shredded material and the recycling channels. It mediates the separation process, directing each material type to the appropriate channel, preventing plastics from being incinerated while enabling metal recovery.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If indiscriminate shredding is performed to ensure security, then confidential information is destroyed, but material qualities are lost and recycling efficiency decreases

Engineering Contradiction:
Improvesecurity of confidential informationVSAvoidrecycling efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Instead of uniform shredding, the system uses selective cutting to remove only specific polluting elements (chip, magnetic stripe, hologram) while preserving the plastic substrate. This segmented approach maintains material qualities for recycling while ensuring security through targeted destruction of confidential elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cutting module applies localized destruction only to specific zones containing confidential information (chip area, magnetic stripe location, hologram position). The rest of the plastic card maintains its intrinsic qualities and structural integrity for efficient recycling.

Inventive Principle:
Principle #3Local quality

4Reliability

If complete shredding-grinding is performed to ensure security, then confidential elements are destroyed, but material losses increase and recycling becomes less efficient

Engineering Contradiction:
Improvedestruction of confidential elementsVSAvoidmaterial losses
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The invention extracts only the polluting and confidential elements (chip, magnetic stripe, hologram) from the plastic card through selective cutting. The plastic substrate is separated and preserved for recycling, minimizing material losses while ensuring complete destruction of confidential information in the extracted elements.

Inventive Principle:
Principle #2Taking out (Extraction)
