Solution Overview

Problem

Existing methods for destroying data on hard drives are inefficient, as they either consume excessive energy or do not allow for the recovery of valuable rare earth elements, and there is a need for a system that can reclaim these elements while ensuring data destruction.

Innovation Solution

A system that identifies and extracts selected components from hard drives, including those containing rare earth metals, using a combination of scanning, milling, and grinding processes to separate and destroy data-containing portions, while recovering valuable materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entire hard drive is completely shredded to destroy data, then data destruction is achieved, but excessive energy is consumed and rare earth elements cannot be recovered

Engineering Contradiction:
Improvedata destructionVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The hard drive is divided into separate components: the data-containing platter is isolated and destroyed individually, while the motor assembly containing rare earth elements is separated and preserved for recycling. This segmentation allows targeted destruction of only the necessary portion without wasting energy on the entire drive.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The valuable motor assembly containing rare earth elements is extracted and removed from the hard drive before the destruction process. This extraction enables the destruction of the platter with minimal energy consumption while preserving the recoverable components for recycling.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the entire hard drive is completely shredded to destroy data, then data destruction is achieved, but rare earth elements cannot be recovered for recycling

Engineering Contradiction:
Improvedata destructionVSAvoidrare earth elements
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The hard drive is segmented into the platter (containing data) and the motor assembly (containing rare earth elements). This segmentation enables selective processing where the platter is destroyed for data security while the motor assembly is preserved intact for element recovery and recycling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The motor assembly containing rare earth elements is extracted from the hard drive before destruction. This extraction prevents loss of valuable substances by separating them from the portion that must be destroyed, enabling subsequent recycling processes to recover the rare earth elements.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If data is merely erased by computer commands, then the process is simple and fast, but the data can be recaptured and is not securely destroyed

Engineering Contradiction:
Improvedata erasure speedVSAvoiddata destruction security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The data-containing platter is extracted as a separate component from the hard drive. This physical extraction enables secure destruction of the platter through shredding or melting, ensuring data cannot be recaptured, while maintaining efficiency by processing only the necessary component rather than the entire drive.

Inventive Principle:
Principle #2Taking out (Extraction)

4Loss of substance

If the entire hard drive is processed to recover rare earth elements, then element recovery is maximized, but data destruction is not ensured and valuable materials are wasted

Engineering Contradiction:
Improverare earth elements recoveryVSAvoiddata destruction
Core Design Contradiction:
Loss of substanceVSReliability

Solution Approach 1:

The hard drive is segmented into the platter (data-containing) and motor assembly (element-containing). This segmentation enables simultaneous achievement of data destruction by processing the platter separately and element recovery by processing the motor assembly, avoiding waste of valuable materials.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The motor assembly containing rare earth elements is extracted and removed from the destruction process. This extraction ensures that while the platter is destroyed for data security, the valuable elements in the motor assembly are preserved and can be recovered through recycling processes.

Inventive Principle:
Principle #2Taking out (Extraction)
